They are designed to install in the Dell OptiPlex 7040 and 7050 Micro PCs and the Wyse 7000 Series thin clients.M.2 is known as the “next generation form factor” and is a specification for internally mounted computer expansion cards and associated connectors. Desktop PCs are being replaced by smaller computing devices (such as Thin Clients, Micro PCs, Ultrabooks, and Tablets) which typically have internal M.2 interfaces but do not have PCI or PCIe slots. Many users still need fiber Ethernet access, and without the external PCIe slot, there is no standard fiber interface on these devices.See the Dell OptiPlex 7040M Owner's Manual for important notes, cautions, and warnings. Read the section “Before working inside your computer” before proceeding.Transition Networks M.2 Gigabit Ethernet Fiber Network Interface Card (NIC) provides a fiber optic interface for the Dell OptiPlex™ 7040 and 7050 Micro PCs and the Wyse 7000 Series thin clients. The NM2-GXE-2230-xx-01 or NM2-GXE-2230-xx-01-D consist of a M.2 NIC that installs into the OptiPlex Micro PC’s M.2 “E key” interface, a fiber optic adapter that installs into the OptiPlex Micro PC’s Option port, and a 20-pin Flat Flex Cable (FFC) with right-angle bend that connects the NIC to the fiber adapter.

1When multiple routing protocols have a route to the same destination network, what determines route is installed in the routing table?best metriclowest hop countgreatest available bandwidthlowest administrative distancelowest cost2A growing medium-sized manufacturing company recently began to have routing instability issue company uses static routes and has a mixture of over 30 Cisco and non-Cisco routers. The netw administrator has decided to convert the network to dynamic routing. What characteristics of pro should be considered in this selection process?Distance vector routing protocols, such as RIP, converge more quickly than do link-state rou protocols.EIGRP can be used on all of the routers in the company.OSPF can be used between the routers.An exterior routing protocol, such as BGP, is recommended for growing companies.3An engineer creates a static route by entering the Router(config)# ip route 10.0.0.0 255.255.25 192.168.1.2 command. What can be concluded about this route?The administrative distance of this route is 1.192.168.1.2 is the address of an interface on this router.This route will display as a directly connected network in the routing table.Packets with a destination IP address of 192.168.1.2 will be forwarded to the 10.0.0.0/24 ne 4W hat is the purpose of a routing protocol?It is used to build and maintain ARP tables.It provides a method for segmenting and reassembling data packets.It allows an administrator to devise an addressing scheme for the network.It allows a router to share information about known networks with other routers.It provides a procedure for encoding and decoding data into bits for packet forwarding.5Which two conditions would create a setting where the use of a distance-vector routing protocol efficient? (Choose two.)the network requires a special hierarchical designfast convergence of the network is crucialthe network is using a hub and spoke topologythe network is using a flat designthere are more than 15 hops between the most distant routers6Which command would the network administrator issue to determine if load balancing is in effect on a router?show ip protocolsshow ip routeshow ip interface briefshow ip interface7W hich of the following best describes the operation of distance vector routing protocols?They use hop count as their only metric.They only send out updates when a new network is added.They send their routing tables to directly connected neighbors.They flood the entire network with routing updates.8Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)Administrative distance refers to the trustworthiness of a particular route.A router first installs routes with higher administrative distances.The value of the administrative distance can not be altered by the network administrator.Routes with the smallest metric to a destination indicate the best path.The metric is always determined based on hop count.The metric varies depending which Layer 3 protocol is being routed, such as IP or IPX.9T he following line of code is present in the routing table:O 10.16.1.0/27 [110/129] via 192.168.1.5, 00:00:05, Serial0/0/1What does the number 129 indicate in this output?The cost for this link has a value of 129.The clock rate on this serial interface is set to 129,000.The next-hop router is 129 hops away from this router.This route has been updated 129 times in this routing table.10Which of the following conditions must be met in order for a network to have converged?The routers in the network are operating with dynamic routing protocols.The routers in the network are operating with compatible versions of IOS.The routers in the network are operating with the same routing tables.The routers in the network are operating with consistent routing knowledge.11Refer to the exhibit. Router1 and Router2 are running EIGRP. All interfaces are operational and packets can be forwarde networks. What information will be found in the routing table for Router1?Router1 will have 6 directly connected networks.The administrative distance of the route to network 172.16.0.0 will be 90.The metric for routes to 172.16.0.0 will be 1.The interface that is used to forward packets to 172.16.0.0 will always be the S0/1 interface.12W hich two statements are true regarding the advantages of the use of static routes? (Choose two).increased securityreduced effort in configuring routesthe administrator maintains control over routingeasier to implement in a growing networkreduces the chance of routing errorsincreased router resource usage13The following line of code is displayed in a routing table:R 209.165.201.0/24 [120/2] via 192.168.252.2, 00:00:16, S0/0/0What can be concluded from this output?A packet destined for host 192.168.252.2 will be forwarded out the interface connected to network 209.165.201.0/24The value, 120, is used to determine the best path when a router has more than one routing protocol configured for t destination network.This route was manually configured using the ip route command.192.168.252.2 is an interface on the router that produced this output.14W hat will be the result of the following commands?ORL(config)# interface fastethernet 0/0ORL(config-if)# ip address 172.16.3.1 255.255.255.0ORL(config-if)# no shutdownThe 172.16.3.0 network will be routed by any dynamic routing protocol automatically.A routing table entry is made to the 172.16.3.0 network with a code of "C".A static route is required to route traffic to the 172.16.3.0 network.The commands will be saved to the startup-configuration automatically.15Which two statements are true regarding classless routing protocols? (Choose two.)sends subnet mask information in routing updatessends complete routing table update to all neighborsis supported by RIP version 1allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topologyreduces the amount of address space available in an organization16Which two statements are true regarding metrics? (Choose two.)RIP uses bandwidth as a metric.OSPF uses delay as a metric.EIGRP uses bandwidth as a metric.OSPF uses cost based on bandwidth as a metric.RIP uses delay as a metric.EIGRP uses hop count only as a metric.17W hy is fast convergence desirable in networks that use dynamic routing protocols?Routers will not allow packets to be forwarded until the network has converged.Hosts are unable to access their gateway until the network has converged.Routers may make incorrect forwarding decisions until the network has converged.Routers will not allow configuration changes to be made until the network has converged.18Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?R1 will install a RIP route using network A in its routing table because the administrative distance of RIP is higher thaR1 will install a RIP route using network A in its routing table because the path cost from RIP is lower than EIGRP.R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is loR1 will install an EIGRP route using network B in its routing table because the path cost from EIGRP is lower than RR1 will install an EIGRP route and a RIP route in its routing table and load balance between them.19Refer to the exhibit. If RIP is the routing protocol, what is the value of the metric from router A to network 192.168.5.0/24?345662472420 A router learns two paths with equal metrics to a destination network via the RIP routing protocol. How will the router handlthe destination network?The router will install the first route it learned into the routing table.The router will install both routes in the routing table and load balance between the two.The router will put the first route in the routing table, and denote the second route as a backup route.The router will pick the path with the higher bandwidth and will place it in the routing table.。

THE NATIONAL EDUCATION SERVICEB:The Chief Whip and Party Chairman to see you.PM:Take a seat, I’ll be right with you.Bernard, take a seat. I want you here for this meeting.B: But, isn’t this a party matter?PM: It’s also a government matter. It’s about our education policy.B: The government’s or the party’s?PM: It’s the same thing.A1: With respect, PM, they’re not the same thing.A2: That’s why we want the meeting.B: Well, it seems to be a party…PM: Bernard, sit! Stay!Now, what’s the problem?A1: Education.PM: Now, what do you think I can do about it?A2: You’re the PM.PM: Yes, I know, and I have no direct control over education, as such, I mean I don’t control the curriculum, I don’t control the exams, Idon’t control the choice of head teacher, nothing.A1: But the voters are holding you responsible for everything was going wrong, you do have influence.PM: And I’m absolutely fled up with it. When I became PM, I thought Iwas had get power. What have I got? I’ve got influence, that’s all. I’ve got no power over the police, the rates, EEC directives, European courts, our courts, the judges, NATO.What have I got the power to do?A1: Have the power to lose us the next election.A2:Which you will if you don’t do something about education.A1:The voters want something done about low academic attainment, none competitivelythought, sex education.PM:I’m not against sex education.A1: Oh I’m not against children being taught the facts of life in the classroom, but not homosexual technique. Or heterosexual technique comes to that.PM: Well where should they learn it then?A1: Behind the bike sheds like we did!PM: Did you?A2: Never mind sexual technique. Some of our schools are teaching more Hindi than English.PM: I know the English is more important than Hindi, but Idaren’t say so in public, I’d be accused of racism.A2: Yeah, but I…PM: Last week when I met the Ethnic Awareness Council, I happened to glance at my watch when a black woman delegate was speaking, I was immediately accused of racist body language.B: And sexist body language.PM: Anyway I get the message. What do you want me to do?A1: We want to you get a grip on education.A2: Get Henry to do something about the Department of Education and Science. PM: He won’t. They’ve got him completely house-trained.A2: Then sack him.PM: I can’t have another Cabinet convulsion, not yet.A1: Then invite the leader of the opposition’s wife here.PM: What can she do?A1: Start measuring up for carpets and curtains.B: Yes, right, fine. This afternoon?H: Bernard, I believe the Prime Minister wants to see me.B: Yes, Sir Humphrey.H: What’s his problem?B: Education.H: Well, i t’s a bit late to do anything about that now.B: No, no, the education system.H: I see. Well it’s be late to do anything about that either.B: Well he thinks he’s going to lose the next election.H: Well worse things could befall the nation.B: He can’t ignore facts.H: If he can’t ignore facts, he’s got no business being a politician. Anyway, Bernard, he’s got nothing to worry about. The education system does all the most parents require of it, keeps children out of mischief while they’re at work.B:Yes, but that paper the Party Chairman showed the PM suggests the whole the comprehensive system is break down, isn’t it?H: Bernard, I never thought to hear such language from a loyal member of the Civil Service! Have you got at by the enemy?B: You mean the Russians?H: No, Bernard, Idon’t. I mean the Prime Minister’s political advisor, that Wainwright female.B: But comprehensive education was an experiment, sure it ought to be validated. H: Yes, of course, but not invalidated.B: But if it was introduced to improve educational standards.H: Whatever gave you that idea?B: You mean it was to get rid of class distinction?H: Precisely!B: So that all children…H: Children? Who mentioned children?B: But I just thought...H: The Department of Education never mentions children! No, no, no, no, Bernard. It was to get rid of class distinction in the teaching profession. Improve the living standard of teachers, not the educational standards of children. Bring the NUT teachers in the primary and secondary mountains up to the salary level of theirrivals in the National Association of Schoolmasters in the grammar schools.B: But the Department…H: Bernard, when there is a Labour government, the Education Department says the comprehensives abolish the class system, and when there’s the Tory government, they say that it’s the cheapest way providing message education. To Labour, we explain that selective education is divisive, and to the Tories we explain that it is expensive. That way, we have a happy relationship with the NUT, and we educate our own children privately.B: But if the government wants change…H: The teaching unions don’t.B: But isn’t it our job to persuade unions to accept government policy?H: No, Bernard, it is our job to get the government to accept union policy, and since government change policy all the time, and unions never change their policy at all, in practice common century require that it is the government who must be brought in line with the unions.B: Yes, PM? Oh, fine. He can see you now.Sir Humphrey, he’s very worried that he seems responsible for something he can’t change.H:Yes, I’m sure. Responsibility without power-the prerogative of the eunuch throughout the ages.Good morning, PM.PM: Good morning, Humphrey. What there were you say?H:Oh, nothing, PM. I understand that you’re worried about the local education authority.PM: No, Humphrey, I’m worried about the Department of Education and Science. H: Indeed? In my opinion, the DES does a splendid job.PM:Look, what happened to education in this country. This is a question from a Religious Studies paper, “Which do you prefer-atom bombs or charity? ”Evenmath become politicized. “If it costs 5 billion pounds a year to maintain Britain’s nuclear defences and 75 pound a year to feed a starving African child, how many African children could be saved from starvation if the Minister of Defence abandoned nuclear weapons?”H: That’s easy, none. They’d spend it all on conventional weapons. In any case, it’s just a sum. Five billion divided by 75.PM: But the children aren’t learning how to do the sums.H: No, indeed. But the local education authorities might argue that they don’t need to know how it’s done.PM:Look, we were all thought basic arithmetic, weren’t we?H: Were we? What’s 3,947 divided by 73?PM: Err… Oh, I’d need a pencil and paper to do that.No, never mind. I could do it when I left school.H: But now you’d use a calculator.PM: That’s not the point. I mean, look at Latin. Hardly anybody knows that now.H: “Tempora mutantur, nor et mutanur in illis.”PM: What?H: Time change and we change with the times.PM: Oh, precisely.H: Si tacuisses, philosophus manisses.PM: What does that mean?H:“If you kept your mouth shout, we might thought you were clever.”PM: I beg your pardon?H: Oh, not you, PM. No, that’s the translation.B: No one would ever have thought Sir Humphrey was saying that about you.H: Go away, Bernard, please.PM: I don’t believe it, Humphrey. You had a conventional strict academic upbringing.Are you denying the value of it?H: But what’s the use of it? I can’t even call upon it in conversation with the PM of Great Britain.PM: Education in this country is a disaster. We supposed to be preparing children for working life, three quarters of the time they’re bored stiff.H: Well, I should thought being bored stiff for the three quarters of the time was an excellent preparation for working life.PM: The school leaving age was raised to 16, so they could learn more, now they’re learning less.H: We didn’t raise it to they’d able to learn more. We raised it to keep teenagers off the job market, and hold down the unemployment figures.PM: Are you saying there’s nothing wrong with education in this country?H: No, of course not, PM. It’s a joke. It’s always been a joke, and as long as you leave it in the hands of local councillors, it will remain a joke. I mean half of them are your enemies anyway and the other half of sort of friends make you prefer your enemies.PM: What are you saying?H:I’m saying that education will never get any better as long as it’s subject to all that tomfoolery in the town halls. I mean just imagine what will happen Iyou put defence in their hands of local authorities.PM: Defence?H: Yes, give the local councils 100 million each and ask them to defence themselves, we would never to worried about the Russians, we’d have a civil war in three weeks!PM:You just being silly.H:Am I? PM, well, that’s what happen to education, and why? Because nobody thinks education is serious the way defence is serious.PM: You mean that’s why civil defence left the hand of local authorities?H:Of course. Because everybody knows it’s a joke. You just don't have important matters in the hand of those clowns. And as you’ve left education to them, you have attached little importance to it.PM: I think it’s extremely important. It could lose me the next election.H: In my naivety, I thought you were concerned about the future of our children.PM: Yes, that too. After all, they get the vote at 18.H: Well, then, PM, then centralise. Take it away from the local councils. Put it under the Department of Education and Science, you could actually do something about it.PM: Do you think I could? Grasp the nettle, take the bull by the horns?B: PM, you can’t take the bull by the horns if you’re grasping the nettle.PM: Oh, really, Bernard?B: Oh, I mean was if you grasp the nettle with one hand, you could take the bull by one horn with the other hand, but not both horns because your hand isn’t big enough, and if you did take the bully by one horn, it would be rather dangerous because… well, it was just mixed metaphors, since we were discussing education, I…I do…Thank god! Yes, oh, it’s your, your political advisor outside.PM: Send her in, would you, Bernard? Humphrey, thank you.H: Thank you, PM.PM: You’ve given one much food for thought.H: in that case, PM, bon appetit.Dear lady.PM: Yes, Dorothy?D: My notes from the program to your tour of the north-west.B: PM, only this is to hospital and factories, PM.PM: Hmm, yeah, drumming up notes in marginal constituencies.B: No, PM.PM: Why not?B: Well, I’m coming with you if it’s a government tour. But if it’s canvassing marginal, it’s a party event. I can’t come and the Treasury can’t pay.D:It’s a government visit, Bernard. It’s pure coincidence that all the stop-offs are in marginal.B: Oh, well, that’s all right, then.PM: That’s OK. Dorothy, what can I do about education? Quickly.D: You mean do or appear to do?PM: Oh, appear to do, I can’t do, obviously.D:Well, oh, in the short term, we could get you on TV associated with something good and successful in education.PM: Good, is there something?D: Well, I had thought of this for your schedule. You could fit it in.PM: St Margaret’s School Young Enterprise Scheme.D: Yes, the school is set up its own manufacturing and trading company. They make cheeseboards, paperweights, toast racks, and so on. Mark and sell them and track the operation in their math and business-study classes. They involved local businessmen. Parents help too.PM: Sounds great, does it cost a lot?D: No, they give the money to local charity.PM: Fine, I’ll do it. Make sure the TV crews have plenty of time to cover me… oh, cover the event, probably. Write me a speech with a snappy, 20 second piece for the news polities. That should win back a few seats.B: PM.PM:Give a lead to those responsible for the nation’s education, Bernard.B:Of course, PM.NEWSREADER: And finally this morning, the PM visited St Margaret’s School on his north-western tour. The school has set up it only a little manufacturing business where the children make a variety of goods in the school carpentry shop for sellingthe local community. The children do their own sales and marketing, and use the experiences they gain from the enterprise as a basis for their math and business studies. The PM was presented with an example of the school’s output. PM: And in conclusion, I must congratulate you on all the hard work, the discipline and the success of your enterprise. You’ve set an example in British education which other schools would do well to follow. We need more schools like StMargaret’s, and I shall always treasure your present. No PM ever lost a sear if he could help it!NEWSREADER: And that was the six o’clock news from the BBC.PM: I thought that was OK, didn’t you?D: Fine.PM:My joke went down well.D: My joke!PM: Better than Channel 4 coverage anyway. They didn’t describe it as the PM’s tour of the north-west. They said,”Jim Hacker touring the marginal constituencies.”A: That’s true, isn’t it?PM: Yeah, but they shouldn't say it like that. That’s biased reporting!A: Reporting the facts?PM: Anyway, there’s nothing wrong with visiting the marginal.A: But what they said was still true.PM: But it was still biased to say it!A: Oh, darling, I’m not interested your paranoia, I was interested in that school.D: Yes, parents queue up to get their children into it.A: What a pity they can’t all get in.More coffee?PM: Hmm.D: Lovely.A: Why can’t more parents send their children there?PM: No room.D: There is room. Actually, school numbers are falling.PM: Yeah, but that mean poaching the other schools.A: So what’s wrong with that?PM: Well, the other schools wouldn’t have enough people so they have to close.A: Great! St Margaret’s could take over their buildings.PM: Oh, darling, couldn't do that, wouldn't be fair.A: Who to?PM: The teachers in the schools that had to close.A: But the good teachers will be taken on by the popular school. They’ll be needed. PM: What about the bad teachers? It wouldn't be fair on them.A:What about being fair on the children or rather bad teacher’s jobs more important?PM: Darling, it’s… it’s no good, no way. Who’s to say who are the bad teachers? It just wouldn't work.A: Why not?PM: Well… it wouldn't work.D: Why not?PM: What do you mean?D: Well, suppose schools were like doctors. I mean after all, under the National Health Service you can choose whichever doctor you like to go to, can't you?PM: Yes.D: And he gets paid per patient. Well, why don’t we do the same with schools? Havea National Education Service. The parents could choose the schools they want,and the school get paid per people.A: Exactly!PM: There’d be an outcry.D: From the parents?PM: Well, not from the parents, from the Department of Education.D: Well, I see. And who has the most votes?PM: No, the DES would block it.D: Fine, get rid of them.PM: What?D: Get rid of the Department of Education.PM: I don’t understand you.D: Get rid of it abolish it, remove it, expunge it, eliminate it, eradicate it, exterminate it!Get rid of it!PM: Get rid of it?D: Yes.PM: I couldn't do that.D: Why not? What does it do?PM: I could do that. Local government could administer the lot. We could have a National Board of School Inspectors. I could send that house-trained idiot Henry to the House of Lords. Golly, I wonder what Humphrey will say.D: Whatever he says, I want to be there when you tell him.PM: To witness the clash between the political will and the administrative will?D:I think it will be the clash between the political will and the administrative won’t.H: You sent for me, PM?PM: Oh, Humphrey, come in. sit down. I just want to bounce an idea off. I’ve realised how to reform the educational system.H: Excellent, PM.PM: I’m going to let parents move their children to school they want.H:Well, you mean, after application, scrutiny, tribunal hearing and appeals procedures?PM: No, just move them whenever they want to.H: I’m sorry, I don’t quite follow.D: This government will let parents decide which school to send their children to. H: PM, you can’t be serious!PM: I am.H: But it’s preposterous!D: Why?H: You can’t expect parents to make these choices. I mean how on earth would parents know which schools are best?PM: Which school did you go to, Humphrey?H: Winchester.PM: Was it good?H: Oh, excellent, of course.PM: Who chose it?H:My parents, naturally. Now, that’s different, PM. My parents were discerning people. You can’t expect ordinary people to know where to send their children. D: Why not?H: Well, how could they tell?D:They tell if their kids could read, write and do sums, they could tell their neighbours what happen about school, and they could tell if the exam results were good.H: Exam results aren’t everything, PM.D:That’s true, and those parents who don’t want to academic education for their children can choose progressive schools.H:But parents have no qualifications to make these choices. I mean teachers are professionals. Parents are the worst people to bring up children. They’ve no qualifications, no training. You don’t expect untrained teachers to teach. The same should apply to parents.PM: You mean, before being have children, they should be trained?H: No, that’s no problem. They've all been trained to have kids. Sex-education classes have been standard for some years.PM: See, well, perhaps we could do better. Before people relived have children, we should make them sit exams, written and practical, perhaps both. And then they could be issued with breeding licences.H: Oh, very droll, PM. No but I’m being serious. It’s looking after children that parents are not qualified for. That’s why they have no idea which schools to choose. It couldn't work.D:Then how does the Health Service work? People choose their family doctor without having medical qualifications.H: Ah, yes, well, that's different.D: How?H: Well, doctors are… The patients aren’t parents, dear lady.D: Oh, really? What makes you think that, Humpy?H: Not as such. In any case, as a matter of fact, I think letting people choose doctors isa very bad idea, very messily. Much tidier to allocate people to GPs, much fairer.Then everyone has an equal chance of getting the bad doctors.PM: I see.H: In any case, we’re not talking about hospital, we’re talking education. And with respect, PM, I think that the DES will react with some caution to your rather novel proposals.PM: You mean they'll block it.H:I mean they will give it more serious urgent consideration, and insist on a thorough and rigorous examination of all the proposals, allied to a detailed feasibility study and budget analysis, perform producing a consultative document for consideration, and seeking comments and recommendations to be included ina brief for a series of working parties, who will produce individual studies whichwill provide the background for a more wide-ranging document, considering whether or not the proposal should be taken forward the next stage.PM: You mean they'll block it.H: Yeah.PM: No problem.D: We thought you’d say that.PM: We have a solution.H: Oh, yes?PM: We’ll abolish the DES.H:I’m sorry?PM: We’ll abolish it.H: Abolish it?D: Why not?H: Abolish Education and Science?! That’d be the end of civilisation as we know it!PM: We only abolish the department. Education and Science will flourish.H: Without government department? Impossible!D: Humphrey, government departments are tombstones. The Department of Industry marks the grave of industry, the Department of Employment marks the grave of employment, the Department of Environment marks the grave of environment.And the Department of Education marks where the corpse of British education is buried.PM: What does the DES do? What’s it for? What’s its role?H:I hardly know where to begin! PM. It lays down guidelines, it centralises and channels money into local education authorities and University Grants Committee.It sets standards!PM: Does it lay down the curriculum?H: No, but it would like to!D: Does it select and change head teachers?H: No…PM: Does it maintain school building?H: No…D: Does it set exam?H: No…PM: Does it choose the children?H: No, but…PM: Well how does it affect what my child does at school?H: He supplies 60% of the cash.D: Why can’t the cash go straight from the Treasury to the schools or the University Grants Committee? I mean do we really need 2,000 civil servants to funnel money from A to B?H: The DES also creates a legislative framework for education.PM: There’s not much legislation, surely. Environment could do that. They deal with other local authority matters.H:PM, you can’t be serious! Who would assess forward planning and staffingvariations, variations in people population, density of schooling required in urban and rural areas? Who would make sure everything ran properly?D: 2,500 private schools seem to solve these planning problems everyday for week, Humphrey, without any help from the DES. They simply respond to changing circumstances, supply and demand. It’s easy.H: Who would plan for the future?PM: Are you saying the education in British today is what the department planned? H: Well, of… No, of course not!PM: Is there anything else that the DES does?H: Well, it… it…PM: Well, we don’t need it, then, do we? QED.H: But…PM: Quod erat demonstrandum.A:I really… quite unthinkable. Once they start abolishing departments, the civilisation crumble.H: Barbarians at the gates.A: The return of the Dark Ages.H: Ah… Did anything like this crop up when you were Cabinet Secretary out?A: No, we let them amalgamate departments, but that worked very well.H:Yes, quite. You keep the existing staff, put an extra layer of coordinating management at the top.A:Exactly. But you have to stop the liquidation of the Department of Education, Humphrey. Have you tried discrediting the person who proposed it?H: Well, no point. It was the Wainwright female, so he’s passing it off as his own idea. A: Discrediting the facts behind it?H: Well, it’s a political idea, so obviously facts don’t come into it.A: Massaging the figures?H: No figures are involved. But it’s hard to get the PM to see that it’s a bad idea.A: Of course. It’s actually a very good idea. It just mustn’t happen.H: I wonder whether we oughtn’t to play along with it-in the interests of the nation’s children.A: Never mind the nation’s children. What about our colleagues at the Department of Education?H: Yes, of course. Sorry.A: Humphrey, let’s be clear about this. The only people who’ll like this idea are the parents and the children. Everyone who counts will be against it.H: Teachers’ unions.A: Local authorities.H: Educational press.A:And, of course, the DES. So, what’s the strategy?H: Well, unions can be counted on to disrupt the schools.A: And go on TV saying it’s the government who are causing the disruption.H: Good, yes, and local councils will threaten to turn the constituency parties against the government.A: Fine, the Department of Education will delay every stage of the process, and leak anything that embarrasses the government. We can help you with that at the Campaign for Freedom of Information.H: Oh, thank you, Arnold.A: Ah, thanks.H: But what are we actually going to do… Thank you, Billy. What’s our argument? A: Well, obviously, this new proposal will destroy our educational system.H: Well everybody knows it’s destroyed already.A: Well, we will say… Sorry, the press will say, that it’s government interference in the Department of Education that destroyed it, and this new plan will make things even worse.H: Will that do the trick?A: It always has in the past.H: Yes, but this time the political pressure is stronger.A: Then you must find a political weapon to fight it with.H: What political weapon did you have in mind, Arnold?A: I? That is your concern, Humphrey. Your chance to prove yourself worthy of the high office to which you’ve been called.B: Well, Sir Humphrey. The PM’s ready to see you.H: What’s it about.B: The abolition of the DES, I’m afraid so.H: This is going to be bloody.B:Oh, yes. Just before you going, there’s a one another minor matter I need your advice…H: Is it important, Bernard?B: Well, it’s not important but it’s urgent.H: What is it?B: Well, you know that enterprise school the PM visited…H: Yes, yes.B: When they gave him that stool?H: The stool, yes.B: Well, it’s just come to light that the wood they were using was stolen.H: Bernard, this is hardly… Stolen?B: Yes, it was government property stolen from one of the YTS workshop from pupils who was working at last year.H: How shocking.B: Well, it was inferred to the DES employment, because the theft came to light at a school. They don’t know whether to prosecute. I’m, I’m sorry to bother you with this…H: Don’t mention it, Bernard. Show me in.PM:Oh, come in, Humphrey. Come in, come in! Sit down. Only one item on the agenda today, the abolition of the DES.H: Actually, if there’s only one item, it’s an agendum.B: I don’t think the PM’s got as far as the second declension.PM:I don’t mind your scoring cheap debating points, since you’ve already lost the battle of the DES.H: The DES will be very upset, PM.PM: Does it matter, since they’ll cease to exist?H: Well, the process will take a year or two. They’ll fight tooth and nail.PM: What can they do to me?H: They’re a formidable department.PM: I am a formidable PM.H: Indeed you are, PM. But you might still need their cooperation.PM: Cooperation? From the Department of Education? Don’t make me laugh!H: Fine, fine. I’ll tell them to go ahead with the prosecution, then.PM: Prosecution? What prosecution?H:Oh, it’s hardly worth bothering you with, PM. But that enterprise school where you were televised last week.PM: Yes?H: Yes, well, the profits you see… A model for other schools…PM: Yes, yes, go on.H: Yes, yes, yes. The profits were apparently the proceeds of theft.PM: Theft? What do you mean theft?H: I mean removing goods without the knowledgeor concerned of the owner…PM: Yes, I know the theft means, Humphrey. What do you mean?H: Well, the stool that they gave to you was made from wood appropriated from the local YTS workshops.PM: What do you mean?H: It was nicked. By two of last year’s pupils.B: A pair of nickers.H:Thank you, Bernard. Well, the YTS want to prosecute. Now, the Department of Education could stop them. You know, return the wood and hush it up.PM: Humphrey, millions of people saw me on TV saying that school was an example to Britain!H: Well, it is a sort of example.PM: Humphrey, they mustn’t prosecute!H:Well, I do hope the Department of Education won’t leak the fact that you’re covering up for crooks.PM: You must tell them not to prosecute.H:Well, that would need their cooperation. I can just see the newspaper “Jim’s enterprising crooks”, “The PM has sat on the fence for so long that now he’s become one.”PM: You must persuade them not to prosecute.H: Well, it’s very difficult to persuade people to cooperate if they are actually under a death sentence.PM: Death sentence?H: If you’re thinking of abolishing the department.PM:Oh, oh, that! No, that was just…a vague idea…of Dorothy’s. An idle thought.Nothing serious.H: You’re sure?PM: Positive.H: That’s splendid, PM. Shall we now continue with agendum?PM: Agendum? Oh, yes! We have no agendum.B: We have no agendum today!PM: Business concluded. Alright, Humphrey?H:Yes, PM.。

UCINET 6快速指南说明书

UCINET 6快速指南说明书

UCINET Quick Start GuideThis guide provides a quick introduction to UCINET. It assumes that the software has been installed with the data in the folder C:\Program Files\Analytic Technologies\Ucinet 6\DataFiles and this has been left as the default directory.When UCINET is started the following window appears.Change default directory button Current default directoryThe submenu buttons give access to all of the routines in UCINET and these are grouped into File, Data, Transform, Tools, Network, Visualize, Options and Help. Note that the buttons located below these are simply fast ways of calling routines in the submenus. The default directory given at the bottom is where UCINET picks up any data and stores any files (unless otherwise specified) this directory can be changed by clicking on the button to the right.Running a routineTo run a UCINET routine we usually need to specify a UCINET dataset and give some parameters. Where possible UCINET selects some default parameters which the user can change if required. Note that UCINET comes with a number of standard datasets and these will be located in the default directory. When a routine has been run there is some textual output which appears on the screen and usually a UCINET datafile contain the results that again will be stored in the default directory.We shall run the degree centrality routine to calculate the centralities of all the actors in a standard UCINET dataset called TARO. First we highlight Network>Centrality>Degree and then clickThis will bring up a box as followsIf you click on the help button then a help screen will open which looks like this. The help file gives a detailed description of the routine, explains the parameters and describes the output that will appear in the log file and on the screen.Close the help file and either by clicking on the pickfile button or by typing the name select the TARO data for analysis as follows.Now click OK to run the routine to obtain the following.This is a text file giving the results of the routine. Note you can scroll down to see more of the file. This file can be saved or copied and pasted into a word processing package. When UCINET is closed this file will be deleted. Close this file.Note when the program was run we also created a new UCINET file called FreemanDegree. We can look at the new UCINET file using the Display dataset button. This is the D button that appears just below the Tools submenu (see the first diagram). Clicking on the D goes straight to the open file menu and bypasses some of the display options that are available if you used Data>Display. Click on display and select FreemanDegree. You should get the followingNote that this file has all the measures of centrality (but not sorted as in the text output) but does not have the descriptive statistics produced in the log file.Using the spreadsheet editorThe spreadsheet editor can be used to amend any data or enter new data. It is also very useful for transferring UCINET data (such as centrality scores) to Microsoft Excel or SPSS. Note that the dl format provides a more sophisticated and flexible way of entering data and this is not covered in this introductory guide. If you click the spreadsheet button or under data run the data editors and click on matrix editor you will open up the spreadsheet editor and obtain the following. Note we have annotated the important buttons and areas of the editor below.To see what a dataset looks like in the editor click file then open and select PADGETT. This is a non-symmetric binary data set with two relations and labels. Once open it will look like this. Symmetric mode copies cell values into other half Set the network or matrix size hereWe see the two relations PADGM and PADGB in the bottom left, clicking on the tabs changes sheet and we are viewing different relations. The labels are repeated along the rows and columns and are in the shaded area. We see the data has 16 actors as shown by the dimensions box on the right. This data can be edited and saved from the spreadsheet.Running NetdrawClick on the Netdraw button to launch Netdraw. This results in a new window which looks likeTo use Netdraw it is important to load in a network first. We shall load in a standard UCINET dataset collected by Dave Krackhardt. Click on the load a file button and type or select the file Krack-High-TecThen click OK and you should see something like this. Click on the Rels tab indicated here.You will now see this data has three relations Advice, Friendship and Reports to. If a relation is ticked then the edges relating to it are displayed. We shall now bring in an attribute file associated with this data called High-Tec-Attributes. Click on the load a file button again load the file but also click the radio button for node attributes under Type of Data so you haveNote you can also click the button just to the right of the load button (with an A) and this will open up the same box but with the attribute button selected. Click on Transform> Node attribute editor and you will see the node attribute editor open up as follows.You can use this editor to change or add in new attributes.We are going to size the nodes by age, colour them by department and shape them according to level. Close the attribute editor and click on the colour node button. This will open the color box click the select attribute button and select department as followsThis will give 5 colours for the five departments. Now click on the change shape of nodes button and go through the same process but selecting level and clicking on the tick at the bottom of the box. This will produce three shapes. To size the nodes according to age you need to selectProperties>Nodes>Symbols>Size>Attribute-Based and then select Age leaving the other values as defaults. This should result in the following.To export the diagram for use in a publication or to read into a word processing package useFile>Save Diagram As>Metafile. To save the diagram as a file you can see again in Netdraw you need to use File>Save Data As>Vna.Using the dl editor in UCINETThe UCINET spreadsheet editor is useful for making changes or for constructing small networks but is not well suited for importing larger datasets in which the data is not typically arranged in an adjacency matrix format. UCINET supports a variety of data formats that are accessed through an editor called the dl editor which is launched by pressing the button to the right of the spreadsheet editor in UCINET which looks like thisLaunch dl editorby clicking thisbutton10When the editor is launched it will contain a small help screen this relates to the info tab. You should click the data tab to obtain the following.Click the data tab to revealthe spreadsheetData format selectionThere are a number of data formats supported but we will just look at two. The data formats can be selected from a pull down list by clicking the arrow to the right of the data format selection box. The full matrix is the same as using the normal spreadsheet editor. Our first format is called nodelist (1mode), this format lists each node followed by the nodes it is adjacent to. The following is an example note we have clicked the force symmetry box in the output options.The first number in each row gives the starting node of an edge the numbers that follow in the same row are a list of end nodes. Hence the first row 1 3 4 5 states that actor 1 is connected to actors 3, 4 and 5. The second row states that actor 5 is connected to actor 6 and so on. Note that there is no order amongst the rows nor within the rows. Actor 2 has no end nodes listed and hence is an isolate. The network corresponding to this linked list is given below.Note that the entries in the spreadsheet are labels and so we can use names rather than numbers. If the data is directed then the arc goes from the start node to the end node. The following is an example showing a directed network with labels.If the data is valued then we cannot use the nodelist (1 mode) format; an alternative is the edgelist (1-mode) format. This format has three entries per line and is of the form start node, end node , value. The following is an example.In this example we see that Martin has a connection to Steve with a value of 5. It should be noted that the data in the spreadsheet cannot be saved except as a UCINET file and hence it is a good ideato construct these in an excel spreadsheet and copy and paste or import them. Once the entry is complete the file can be saved in UCINET by clicking the File button and selecting Save UCINETdataset. To clear the spreadsheet click the on the top left hand side.There are many features of UCINET and Netdraw that we have not mentioned but hopefully this guide will get you started.。

MASCHINE!MASCHINE is a groove production studio that implements the familiar working style of classi-cal groove boxes along with the advantages of a computer based system. MASCHINE is ideal for making music live, as well as in the studio. It’s the hands-on aspect of a dedicated instru-ment, the MASCHINE hardware controller, united with the advanced editing features of the MASCHINE software.Creating beats is often not very intuitive with a computer, but using the MASCHINE hardware controller to do it makes it easy and fun. You can tap in freely with the pads or use Note Re-peat to jam along. Alternatively, build your beats using the step sequencer just as in classic drum machines.Patterns can be intuitively combined and rearranged on the fly to form larger ideas. You can try out several different versions of a song without ever having to stop the music.Since you can integrate it into any sequencer that supports VST, AU, or AAX plug-ins, you can reap the benefits in almost any software setup, or use it as a stand-alone application. You can sample your own material, slice loops and rearrange them easily.However, MASCHINE is a lot more than an ordinary groovebox or sampler: it comes with an inspiring 7-gigabyte library, and a sophisticated, yet easy to use tag-based Browser to give you instant access to the sounds you are looking for.What’s more, MASCHINE provides lots of options for manipulating your sounds via internal ef-fects and other sound-shaping possibilities. You can also control external MIDI hardware and 3rd-party software with the MASCHINE hardware controller, while customizing the functions of the pads, knobs and buttons according to your needs utilizing the included Controller Editor application. We hope you enjoy this fantastic instrument as much as we do. Now let’s get go-ing!—The MASCHINE team at Native Instruments.MASCHINE Documentation1.1MASCHINE DocumentationNative Instruments provide many information sources regarding MASCHINE. The main docu-ments should be read in the following sequence:1.MASCHINE MIKRO Quick Start Guide: This animated online guide provides a practical ap-proach to help you learn the basic of MASCHINE MIKRO. The guide is available from theNative Instruments website: https:///maschine-mikro-quick-start/2.MASCHINE Manual (this document): The MASCHINE Manual provides you with a compre-hensive description of all MASCHINE software and hardware features.Additional documentation sources provide you with details on more specific topics:►Online Support Videos: You can find a number of support videos on The Official Native In-struments Support Channel under the following URL: https:///NIsupport-EN. We recommend that you follow along with these instructions while the respective ap-plication is running on your computer.Other Online Resources:If you are experiencing problems related to your Native Instruments product that the supplied documentation does not cover, there are several ways of getting help:▪Knowledge Base▪User Forum▪Technical Support▪Registration SupportYou will find more information on these subjects in the chapter Troubleshooting.Document Conventions1.2Document ConventionsThis section introduces you to the signage and text highlighting used in this manual. This man-ual uses particular formatting to point out special facts and to warn you of potential issues.The icons introducing these notes let you see what kind of information is to be expected:This document uses particular formatting to point out special facts and to warn you of poten-tial issues. The icons introducing the following notes let you see what kind of information canbe expected:Furthermore, the following formatting is used:▪Text appearing in (drop-down) menus (such as Open…, Save as… etc.) in the software andpaths to locations on your hard disk or other storage devices is printed in italics.▪Text appearing elsewhere (labels of buttons, controls, text next to checkboxes etc.) in thesoftware is printed in blue. Whenever you see this formatting applied, you will find thesame text appearing somewhere on the screen.▪Text appearing on the displays of the controller is printed in light grey. Whenever you seethis formatting applied, you will find the same text on a controller display.▪Text appearing on labels of the hardware controller is printed in orange. Whenever you seethis formatting applied, you will find the same text on the controller.▪Important names and concepts are printed in bold.▪References to keys on your computer’s keyboard you’ll find put in square brackets (e.g.,“Press [Shift] + [Enter]”).►Single instructions are introduced by this play button type arrow.→Results of actions are introduced by this smaller arrow.Naming ConventionThroughout the documentation we will refer to MASCHINE controller (or just controller) as the hardware controller and MASCHINE software as the software installed on your computer.The term “effect” will sometimes be abbreviated as “FX” when referring to elements in the MA-SCHINE software and hardware. These terms have the same meaning.Button Combinations and Shortcuts on Your ControllerMost instructions will use the “+” sign to indicate buttons (or buttons and pads) that must be pressed simultaneously, starting with the button indicated first. E.g., an instruction such as:“Press SHIFT + PLAY”means:1.Press and hold SHIFT.2.While holding SHIFT, press PLAY and release it.3.Release SHIFT.1.3New Features in MASCHINE2.8The following new features have been added to MASCHINE: Integration▪Browse on , create your own collections of loops and one-shots and send them directly to the MASCHINE browser.Improvements to the Browser▪Samples are now cataloged in separate Loops and One-shots tabs in the Browser.▪Previews of loops selected in the Browser will be played in sync with the current project.When a loop is selected with Prehear turned on, it will begin playing immediately in-sync with the project if transport is running. If a loop preview starts part-way through the loop, the loop will play once more for its full length to ensure you get to hear the entire loop once in context with your project.▪Filters and product selections will be remembered when switching between content types and Factory/User Libraries in the Browser.▪Browser content synchronization between multiple running instances. When running multi-ple instances of MASCHINE, either as Standalone and/or as a plug-in, updates to the Li-brary will be synced across the instances. For example, if you delete a sample from your User Library in one instance, the sample will no longer be present in the other instances.Similarly, if you save a preset in one instance, that preset will then be available in the oth-er instances, too.▪Edits made to samples in the Factory Libraries will be saved to the Standard User Directo-ry.For more information on these new features, refer to the following chapter ↑4, Browser. Improvements to the MASCHINE MIKRO MK3 Controller▪You can now set sample Start and End points using the controller. For more information refer to ↑17.3.1, Using the Edit Page.Improved Support for A-Series Keyboards▪When Browsing with A-Series keyboards, you can now jump quickly to the results list by holding SHIFT and pushing right on the 4D Encoder.▪When Browsing with A-Series keyboards, you can fast scroll through the Browser results list by holding SHIFT and twisting the 4D Encoder.▪Mute and Solo Sounds and Groups from A-Series keyboards.

Progammable Items3Cont./Peak CurrentMotor Type200A / 1080ASensored / Sensorless Brushless MotorsMode XERUN XR8 PRO G304Specifications06ESC Setup01DisclaimerNote: If the forward and backward is reverse after installing the motor, please modify “no. 1J” parameters “Motor Rotation” to change the direction.If the 1K parameter item "Phase-AC Swap" is set to "Enabled", then the # A of the esc needs to be connected to the # C of the motor.B. Sensorless Motor Wiring:Users do not need to be worried in r egards to the connectivity with the A/B/C(ESC and motor) as ther e is no polarity. You may find it necessary to swap two wir es if the motor runs in reverse.2. Receiver Wiring:Insert the throttle control flat cable of ESC into the throttle channel (i.e. THROTTLE channel) of the receiver. Since the red line in the flat cable outputs BEC voltage to the receiver andsteering servo. Please do not supply additional power to the receiver, otherwise the electric adjustment may be damaged. If additional power is required, disconnect the redwire on the throttle plug from the ESC.3. Battery Wiring:Please make sure that the (+) pole of the ESC is connected to the (+) of the battery, and the (-) pole is connected to the (-). If connect reversely, the ESC cannot start up. (Add the picture ofconnecting battery here.)4. External Capacitor Module (also called Cappack )Wiring (Optional):Generally, for 1/8 Buggy and 1/10 vehicles, there is no need for external capacitor pack; But for 1/8 on-road racing, due to the high load current, it is necessary to solder the standardcapacitor pack to the input end of the esc (which can be soldered together with the input wires to the gold plug of the esc), as shown in the figure above.Warning! Make sure that the red/positive (+) of the capacitor pack is connected to the red/positive (+) of the esc, and the black/negative (-) is connected to the black /negative (-). Do not connect them incorrectly, otherwise the capacitor pack will be damaged.Warning! This is an extremely powerful system. For your safety and the safety of those around you, we strongly recommend removing the pinion gear attached to the motorbefore calibrating and setting this system. It is also advisable to keep the wheels in the air when you turn on the ESC.1) Illustration of power on/off: Short press the ON/OFF key to turn on the ESC in the off state, and long press the ON/OFF key to turn off the ESC.2) Beep illustration when turn on the ESC: When turn on ESC under normal conditions (i.e. it is started without pressing the SET key), the motor will emit several Beeps to indicate the LiPocells. For example, “Beep, Beep, Beep” means 3S, “Beep, Beep, Beep, Beep” means 4S.Power on/off and Beep illustration208Trouble ShootingIn order to make one firmware applicable to all different racing conditions, there are 3 groups of preset modes in the ESC. Users are able to change the settings of the modes provided andmatch suitable gear ratio. Plug-and -screw. Users can change the settings as per the control feel, track, and rename the setting mode. For example, the name can be changed from “1/8Off-Road” to “NC2020-1900” to indicate the NC2020 uses 1900KV. This can be saved for future reference as well.07Explanation for LED status1. During the Start-up Process• The red light flashes quickly while the motor beeps: the esc has not detect the neutral of the throttle. (the neutral of the throttle does not match the transmitter)• The GREEN LED flashes “N” times indicating the number of LiPo cells you have connected to the ESC.2. In Operation• The throttle triggle is at the neutral:1) In the normal mode(Non blinky mode),the RED LED turns on soild.2) In the blinky mode(Non RPM limit mode), the boost timing and turbo timing are 0, the RED LED will blink.• Forward: The RED LED dies out and the GREEN LED blinks when your vehicle runs forward. The GREEN LED turns solid when pulling the throttle trigger to the full (100%) throttle endpoint.• Brake: The RED LED dies out and the GREEN LED blinks when you brake your vehicle. The GREEN LED turns solid when pushing the throttle trigger to the full brake endpoint and settingthe ”Max. Brake Force” to 100%.• Backward: The RED LED dies out, the GREEN LED blinks when you reverse your vehicle. The GREEN LED turns solid when pushing the throttle trigger to the full brake endpoint and settingthe ”reverse force” to 100%.3. When Some Protection is Activated• The RED LED flashes a short, single flash and repeats “☆, ☆, ☆” indicating the low voltage cutoff protection is activated.• The GREEN LED flashes a short, single flash and repeats “☆, ☆, ☆” indicating the ESC thermal protection is activated.• The GREEN LED flashes a short, double flash and repeats “☆☆, ☆☆, ☆☆” indicating the motor thermal protection is activated.• The GREEN LEDS flash a short, single flash and repeats “☆☆☆, ☆☆☆, ☆☆☆” indicating that the load of ESC is heavy, the Over-Current protection is activated.• The GREEN LEDS flash a short, single flash and repeats “☆☆☆☆☆,☆☆☆☆☆,☆☆☆☆☆” indicating that the temperature of ESC and capacitor is too high, the thermal protectionof capacitor is activated.Preset Modes for Different Racing:Here is the method of setting parameters of ESC:1) LCD G2 programming box set the parameters: (Please refer to the instructions of LCD G2 programming box for detailes)parameters. You can adjust the setting via “ITEM” & “VALUE” buttons, and press the “OK (R/P)” button to save new settings to your ESC.2) Use OTA Programmer to set parameters (Please refer to instructions of OTA Programmer for details)This ESC allows OTA Programmer connecting to the computer, that is, plug the programming wire of OTA Programmer to theprogramming port. Then use mobile phone to install HOBBYWING HW LINK App to set parameters.3) The OTA Bluetooth module:1) The ESC is able to record the Maximum Temperature of ESC and Motor, Minimum Battery Voltage and Maximum Motor RPM in running.It automatically saves the recorded data to the designated area when you turn off the ESC after a run. You can check those data via a multifunction LCD G2 program box. Users need to switchon the ESC after the esc is connected with the program box. Long Press the “OK(R/P)” button on any “item” page, then press the “ITEM” button, the following 5 item pages will be displayed:Mode → ESC Temperature→ Motor Temperature → Min Voltage→ Max RPM2) The ESC running data is read through the OTA Bluetooth module.After connecting the OTA Bluetooth module to the esc and establishing communication, you can view not only the four extreme value data recorded above, but also the real-time runningdata and historical record data (graph) in the [Data Log] menu in HW link app.Programming:5Here is the method of restore factory reset:1) Restore the default values with a multifunction LCD G2 program boxAfter connecting the program box to the ESC, continue to press the “ITEM” button on the program box until you see the “RESTORE DEFAULT” item, and press “OK(R/P)” to factory reset your ESC.2) Restore the default values with a OTA Programmer (Use HW Link mobile phone App)Connect OTA Programmer to the ESC, enter into 【Parameters】, click “reset” to factory reset your ESC.Factory reset6Preset modes41A: Running ModOption 1: Forward with BrakeRacing mode. It has only forward and brake functions.Option 2: Forward/ Reverse with BrakeThis option is known to be the “training”mode with “Forward/Reverse with Brake” function. The vehicle only brakes on the first time you push the throttle trigger to the reverse/brake zone.Ifthe motor stops when the throttle trigger return to the neutral zone and then re-push the trigger to reverse zone, the vehicle will reverse, if the motor does not completely stop, then yourvehicle won’t reverse but still brake, you need to return the throttle trigger to the neutral zone and push it to reverse zone again. This method is for preventing vehicle from being accidentallyreversed.Option 3: Forward and ReverseThis mode is often used by special vehicles. The vehicle will reverse immediately when you push the throttle triggle to the reverse zone.1B: Max. Reverse Force:The reverse force of the value will determine its speed. For the safety of your vehicle, we recommend using a low amount.1C: Lipo Cells:Auto Calculation is the default setting. If Lipo batteries are often used with the same cell count,we would recommend setting the Lipo cells manually to avoid the incorrect “Calculation”(Forexample,the esc may take a not fully charged 3S Lipo as a fully 2S Lipo) ,which may cause the low-voltage cutoff protection to not function ideally.1D: Cutoff Voltage:The ESC will monitor the battery voltage all the time, once the voltage is lower than the threshold value, the ESC will reduce the power to 50% instantly and cutoff the power output in 40seconds. When enters into voltage protection, the RED LED will single flash that repeats (☆, ☆, ☆, ☆…….). Please set the “Cutoff Voltage” to “Disabled” or customized protection thresholdvalue if you are using NiMH batteries.Option 1: DisabledThe ESC does not cut the power off due to low voltage. We do not recommend using this option when you use any LiPo battery as you will irreversibly damage the product. It is suggested toset to “Disabled”(But the battery would be damaged due to overcharged)Option 2: AutoThe ESC calculates the corresponding cutoff voltage as per the number of LiPo cells it detects and the “3.5V/cell” rule. For example, if the ESC detects a 4S, the cutoff voltage protectionthreshold value is 3.5x4=14.0V.Option 3: CustomizedThe customized cutoff threshold is a voltage for the whole battery pack (adjustable from 5.0V to 13.6V). Please calculate the value as per the number of LiPo cells you are using. For example,when you use a 4S and you want the cutoff voltage for each cell is 3.0V, you will need to set this item to 12V(3.0*4)1E: ESC Thermal Protection:The output from the ESC will be cut off with the value you have preset. The GREEN LED flashes (☆, ☆, ☆) when the ESC temperature reaches to the preset value. The output will not resumeuntil the ESC temperature gets down.Warning! Please do not disable this function unless you’re in a competition. Otherwise the high temperature may damage your ESC and even your motor.1F: Motor Thermal Protection:The GREEN LED flashes (☆☆, ☆☆, ☆☆) when the motor temperature reaches to the preset value. The output will not resume until the motor temperature gets down.Warning! Please do not disable this function unless you’re in a competition. Otherwise the high temperature may damage your motor and even your ESC. For non-Hobbywingmotor, the ESC may get this protection activated too early/late because of the different temperature sensor inside the motor. In this case, please disable this function andmonitor the motor temperature manually.1G: BEC Voltage:It supports 6.0V/7.4V adjustable. 6.0V is applicable to common servo. If use high-voltage servo, set to higher voltage according to voltage marking of servo.Note: 1. Do not set the BEC voltage above the maximum operating voltage of the servo, as this may damage the servo or even the ESC.2. Due to the characteristics of the BEC circuit, there is a voltage difference between the BEC output voltage and the input voltage,when the BEC voltage is set to 7.4Vand 2S Lipo is used,the BEC cannot stably output 7.4V (will decrease as the battery voltage decreases) .Therefore,it is recommended to use 7.4V BEC when matchingwith 3S Lipo and above.1H: Sensor Mode:Option 1: Full SensoredIf use XERUN 4268/74-G2/G3 motor, it can set to full sensor mode. The power system will work in the “sensored” mode at all times. The efficiency and drivability of this mode is at the highest.And Boost、Turbo timing can be used and get erupting power.Option 2: Sensored/Sensorless HybridThis is universal driving mode of current 1:8 power system. The ESC operates the motor in sensored mode during the low-speed start-up process, followed by switching to operating the motorin the “sensorless” mode when the RPM is increased.1I: Motor Rotation:With the motor shaft faces you (the rear end of the motor is away from you), increase the throttle input, the motor (shaft) will rotate in the CCW/CW direction if the “Motor Rotation/Direction”set to “CCW/CW”. Generally, the vehicle runs forward when the motor (shaft) rotates in the CCW direction. However, some vehicles only run forward when the motor rotates in the CW directiondue to the different chassis design. In that case, you only need to set the “Motor Rotation/Direction” to “CW”.1J: Phase-AC Swap:If the A/C wire of ESC connect to A/C wire of motor with crossed way (A wire of ESC connects to C wire of motor, C wire of ESC connects to A wire), set this item as Enable.Warning! When #A/#B/#C wire of ESC connect to #A/#B/#C wire of motor correspondingly, do not Set to Enable. Otherwise it will damage the ESC and motor.2A: Throttle Rate Control:This item is used to control the throttle response. It can be adjustable from 1 to 30 (step: 1), the lower the throttle rate, the more the limit will be on the throttle response. A suitable rate canhelp driver to control his vehicle properly during the starting-up process. Generally, you can set it to a high value to have a quick throttle response if you are proficient at throttle control.2B: Throttle Curve:, the throttle output at the early stage will be higher (than the output when the curve is linear); if it is adjusted to –EXP, the throttleNote: The rpm limit value here is the rpm corresponding to the 2 pole motor,when using a 4 pole motor (such as 4268 motor), the corresponding rpm shall be divided by 2.3C: Brake Rate ControlIt’s adjustable from 1 to 20 (step: 1), the lower the brake rate, the more limit on the brake response. A suitable rate can aid the driver to brake his vehicle correctly. Generally, you can setit to a high value to have a quick brake response.3D: Brake ControlOption 1: TraditionalThis mode is the braking method under conventional square wave drive, which is the same as the previous version of esc. The traditional braking method, due to its brakingforce being affected by the motor speed, can cause the braking not being linear/smooth.Option 2: Disc BrakeThis mode is the braking method under FOC drive, the braking force is not affected by the motor speed, with better braking linearity and stronger braking force.3E: ABS ForceThis parameter is used to adjust the braking force maintained after the motor stops rotating. The larger the value, the greater the braking force. Setting this value appropriately accordingto the traction can help improve the situation of wheel lockup and sliding, as well as help control the off-road vehicle's attitude on the hill.Note: This parameter only takes effect when the "Brake Control" is set to "Disc Brake".3F: Disc Brake CurvatureThis parameter is used to set the braking curve in disc brake mode. The higher the curvature, the greater the braking force in the front section;The smaller the curvature, the smaller the braking force in the front section. It can be set according to personal control habits.Note: This parameter only takes effect when the "Brake Control" is set to "Disc Brake".3G: Brake FrequencyThe brake force will be larger if the frequency is low; you will get a smoother brake force when the value is higher, please choose the frequenciesas per the actual test results of your vehicles.Note: This parameter only takes effect when the "Brake Control" is set to "Traditional".4A: Boost Timing:It is effective within the whole throttle range; it directly affects the car speed on straightaway and winding course. The ESC adjusts the timingdynamically as per the throttle amount in the operation. The Boost Timing is not constant but variable.5A: Turbo Timing:This item is adjustable from 0 degree to 48 degrees, the corresponding turbo timing (you set) will initiate at full throttle. It’s usually activated on long straightaway and makes the motorunleash its maximum potential.5B: Turbo Delay:When “TURBO DELAY” is set to “INSTANT”, the Turbo Timing will be activated right after the throttle trigger is moved to the full throttle position. When other value(s) is applied, you willneed to hold the throttle trigger at the full throttle position (as you set) till the Turbo Timing initiates.5C: Turbo Increase Rate (deg / 0.1sec):This item is used to define the “speed” at which Turbo Timing is released when the trigger condition is met. For example, “6 degs / 0.1sec” refers to the Turbo Timing of 6 degrees thatwill be released in 0.1 second. Both the acceleration and heat is higher when the “Turbo increase rate” is of a larger value.5D: Turbo Decrease Rate (deg/0.1sec):After the Turbo Timing is activated and the trigger condition turns to not be met (i.e. vehicle slows down at the end of the straightaway and gets into a corner, full throttle turns to partialthrottle, the trigger condition for Turbo Timing turns to be not met), if you disable all the Turbo Timing in a moment, an obvious slow-down like braking will be felt and cause the controlof vehicle to become bad. If the ESC can disable the Turbo Timing at some “speed”, the slow-down will be linear and the control will be improved.Warning! Boost Timing & Turbo Timing can effectively improve the motor efficiency; they are usually used in competitions. Please take some time to read this manual andthen set these two items carefully, monitor the ESC & motor temperatures when you have a trial run and then adjust the Timing and FDR accordingly as aggressive Timingsand FDR may cause your ESC or motor to be burnt.Note: Only when paired with the Hobbywing matching motor (such as XERUN 4268 G3), Boost and Turbo can achieve a maximum 48 degree effect.Parameters 5A-5D only has function when you set the “Drive Mode” to “Full Sensored”.Diagram of Disc Brake Curvature XERUN XR8 PRO G3USER MANUALBrushless Electronic Speed Controller• Built-in 3 common profiles, suitable for all 1/8 Racing, select and use instantly.
