光伏组件非均匀雪载荷试验-最新国标

光伏组件非均匀雪载荷试验1范围本文件定义了一种测试方法，用于确定有框光伏组件在倾斜的非均匀雪载荷影响下的机械性能。

本文件适用于有框光伏组件，其边框在预期安装后会突出于组件下边缘的前面板玻璃表面，因此对从组件表面滑落的雪形成了额外的阻碍。

本文件不适用具有其他边框结构的组件，如边框组成背面框架结构或侧边、顶边、下边缘边框不会额外阻碍积雪滑落的组件。

本文件所定义的试验方法用于确定有框光伏组件的非均匀机械载荷极限。

本文件规定的载荷试验方法仅适用于模拟自然雪载荷分布。

任何人工积雪分布模式（例如除雪或人为分配行为）需另行考虑。

本文不包括消除或缓解不均匀积雪的方法，如增大安装角度（超过60°）。

本文所假设地面积雪和组件表面积雪之间的系数关系，可能不适用于多次降雪间隔期间积雪未完全消融的情景。

本文件不考虑积雪对组件发电的影响。

虽然试验方法包括载荷测试步骤间的等待时间，但本文件没有对组件材料（如前板玻璃）的疲劳行为进行过完整评估。

由于雪载造成的光伏组件典型现场失效表现为玻璃破裂和边框弯曲，本试验方法旨在重现此类失效发生时的载荷状态。

Neil Pryde Sails Mainsail Lazy Bag MLB Installatio

I N T E R N A T I O N A L D E S I G N A N D T E C H N I C A L O F F I C E Lazy Bag Installation Guide© Neil Pryde Sails International1681 Barnum AvenueStratford, CONN. 06614Phone: 203-375-2626 • Fax: 203-376-2627Email: ************************Web: All material hereinCopyright 2006-2007 Neil Pryde Sails InternationalAll Rights ReservedOVERVIEWThe Neil Pryde Sails Mainsail Lazy Bag (MLB) is designed to be easily used and modular in design. It can conveniently be fitted and removed independently of the sail.•The MLB includes a zippered flap at the front of Array the bag that wraps around the mast to theopposite side of the bag and zippers closed. Thisis designed to reduce U.V. damage and keepbirds from nesting inside the mainsail!•The front flap can be left in place while sailing,or folded back inside the bag and secured with ahook & loop strip.•The top zipper is also provided with a flap tohelp decrease water ingress.•The MLB is attached to the boom usingslug/slides. The bag is NOT sewn between eachslide so that rain water AND reefing lines can beled from the sail through the bag to the boomattachment points.•Two adjustable webbing straps provide Fore/afttension; one strap is passed through the clew ringof the mainsail and the forward strap goesaround the mast (and inside the halyards). Thestraps are inside the bag to reduce U.V. exposure and allow the bag to be pulled aft over the sail, covering itcompletely. A third strap at the front/top can be used to tighten up the forward girth of the bag.•The battens are inserted from the forward end of the bag. The design is such, that the battens themselves become the attachment point for the lazy jacks. This reduces point loading and makes the bag smooth and taunt. Thebattens are locked in place with the internal Velcro closure system. (Identical to the mainsail batten pocketsystem)The following pictorial guide will outline the basic steps to installation.Installation ProcedureGetting Started:Assuming the sail is already in place, pull the entire sail to one side of the boom. This allows you to access the boom slot opening at the front of the boom, just behind the gooseneck.Starting with aft most end (short end) insert the furthest aft slug into the boom at the forward end of the boom just aft ofthe gooseneck and slide it aft. Add each succeeding slug until the cover is pulled aft completely. Both halves of the bag will be on the same side at this time. (Starboard in the photo)Pull one half of the bag underneath the sail and to theopposite side.The aft webbing strap is led through the clew ring of the sail and back into the buckle. The webbing should be pulled tight enough so that the bag covers the aft end of the sail. In the photo at right you can see the sail clew slug is pull out to the black band on the boom. The bag itself extends aft, past theblack band.With this preliminary adjustment made now insert each batten into the pocket. The ‘butterfly’ fitting is designed to seat with the webbing retainer. This means the unfinished batten end is inserted first. Make sure it is completely seated at the very aft end of the bag. At each opening along the sock mark the batten and remove the batten. We suggest that you make a 2” / 50mm wrap of white riggers tape at theselocations…as it will provide good friction and holding power for the lazy jack lines.Re-insert the battens. Pulling the bag tight and with a fair amount of tension on the battens, the battens should be just inside of the pocket fronts. If this is not the case, they are easily trimmed with a hacksaw.Now insert the webbing/Velcro strap folding the webbing over the butterfly end. This will lock the battens in place. This is the very same system as used on the mainsail battens and will require the ‘pusher stick’ that came with your mainsail for this operation.The jacklines are composed of three parts; the upper line that connects to the mast, the aft line that runs from the aft most connection point on the bag, to the upper ring and the forward line.Take your aft line and tie it around the rigging tape on the batten at the last most connection point on the bag. A double or triple clove hitch or fisherman’s bend are both very good knots that will resist slipping and be quite permanent.Tie the forward line in a similar fashion to the mid-attachment point on the bag.Take one turn on the forward line around the batten and pull the entire jackline system tight. The bag side should be pulled up smoothly and tightly.Later should you want, you can tie a overhand ‘shortening loop’ above the bag on the forward line and turn the rope end around the batten and back up to the loop, making a purchase system that can be secured with a couple of overhands.Do the opposite side in the same fashion.With both sides of the bag now pulled up and tight you need to check the fore/aft location of the bag. Do this by bringing the forward flap around the mast (inside the halyards) and zip it closed. If you cannot zip it or if it zips and is quite loose, the bag needs to be adjusted fore or aft depending on location.You will need to slide each slide backward or forward in small increments until the overall position is correct.Once achieved, readjust the webbing and the aft end and at the forward end take the lower strap around the mast (inside the halyards) and make it fast to the other side.The bag should be taut and smooth along the bottom as in photo at right.Both sets of reef lines can now be led down the inside of the bag and out the bottom and tied securely at the reef eye location.The forward upper webbing strap can now be fitted and is normally adjusted to be snug when the front flap is zipped closed. You can tighten it more to squeeze together the girth of the bag if you choose. This strap provides support should you choose to sail with the front flap tucked inside the bag.The aft eyelets can optionally be used to tidy up the trailingedge of the cover should you choose. Some like to tie a small line from the upper eyelets around the topping lift and back for an upward pull. In this photo we have utilized the eyelet on the rear of the boom to secure the lower eyelets. NOTE: In this picture you can clearly see that we havestretched the bag aft over the sail (which actually stops at the black band).Last Look:These final photographs illustrate the bag from a few vantage points.Forward starboard viewWith forward flap folded back inside and secured to the hookand loop strip.Forward line with shortening loop and hitch.Clove hitch at battenPortside view with front flap closed and zipped.Close up view looking aft.Top view looking forward。

MVB简介

MVB简介从70年代开始，国外许多大公司就开始了车载微机的研究，并相继制定了自己的机车总线标准，为了能有一个相对一致的标准，同时也考虑到列车车载微机的进一步发展，国际电工技术委员会IEC的第九技术委员会TC9的第二十二工作组WG22特别制定了列车通信网络的国际标准IEC61375-1,即所谓的TCN标准，在国内这一标准也被列入铁标。

在TCN标准规定的数据流中主要规定了两种用户数据流：消息数据和过程数据，目前，国内的电力机车上，主要应用的是过程数据，信息与控制研究中心的“一类网卡”正是为了适应国内电力机车工业发展的现状和需要而研发生产的。

在研发一类网卡的过程中，借鉴了国内外众多相关公司的经验，并根据用户的实际需求增加了许多新的特性，如：1)单端口地址访问：本网卡只占用主机的一个IO端口地址，方便用户集2)16位接口，数据吞吐量更大：主机访问本网卡时,本网卡自动通知主机以16位数据方式访问，相比传统的8位接口，数据吞吐量增加一倍。

按端口大小往源端口写入数据或从宿端口接收数据：目前，多数厂家网卡对端口数据进行操作时，无论是16位端口还是256位端口，均需按256位端口进行操作，浪费了系统资源。

用户使用本网卡时，可按实际端口大小往端口写入数据，如果是16位端口，仅需进行一次操作，提高了操作效率。

3)对网卡操作时不需要进行“忙等待”查询：由于MVB网卡既要处理CPU的读写操作，又要处理MVB总线上的数据，因此如何避免两方面操作的冲突是一个困难问题。

目前，多数厂家网卡均采用“MVB总线操作优先”方式，在用户对网卡进行操作时，需首先查询网卡是否处于“Busy”状态（处理MVB总线数据），因此CPU对网卡的有效操作大幅度降低，实时性也难于得到保证。

本网卡针对这一问题，在网卡内部设计了特殊的数据缓冲机制，用户对网卡进行操作不需进行“忙等待”查询，极大提高了主机的访问效率，保证了实时性。

4)中断功能：当源端口数据成功发送到MVB总线或宿端口从MVB总线接收到数据时，将向主机发送中断，通知主机可以往源端口放入新的数据，或宿端口中有新数据可供使用。

ASTM D566-2002润滑脂滴点测定法

Designation:D566–02(Reapproved2009)Designation:132/96British Standard2877Standard Test Method forDropping Point of Lubricating Grease1This standard is issued under theﬁxed designation D566;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(´)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This test method covers the determination of the drop-ping point of lubricating grease.1.2This test method is not recommended for use at bath temperatures above288°C.For higher temperatures Test Method D2265should be used.1.3The values stated in SI units are to be regarded as standard.No other units of measurement are included in this standard.1.4This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For speciﬁc hazard statements,see6.4and8.1.2.Referenced Documents2.1ASTM Standards:2D217Test Methods for Cone Penetration of Lubricating GreaseD235Speciﬁcation for Mineral Spirits(Petroleum Spirits) (Hydrocarbon Dry Cleaning Solvent)D2265Test Method for Dropping Point of Lubricating Grease Over Wide Temperature RangeE1Speciﬁcation for ASTM Liquid-in-Glass Thermometers3.Terminology3.1Deﬁnitions:3.1.1lubricating grease,n—a semi-ﬂuid to solid product ofa thickener in a liquid lubricant.3.1.1.1Discussion—The dispersion of the thickner forms a two-phase system and immobilizes the liquid lubricant by surface tension and other physical forces.Other ingredients are commonly included to impart special properties.D217 3.1.2thickener,n—in lubricating grease,a substance com-posed ofﬁnely-divided particles dispersed in a liquid to form the product’s structure.3.1.2.1Discussion—Thickeners can beﬁbers(such as vari-ous metallic soaps)or plates or spheres(such as certain non-soaps thickeners),which are insoluble or,at most,only very slightly soluble in the liquid lubricant.The general requirements are that the solid particles are extremely small, uniformly dispersed and capable of forming a relatively stable, gel-like structure with the liquid lubricant.D217 3.2Deﬁnitions of Terms Speciﬁc to This Standard:3.2.1dropping point,n—a numerical value assigned to a grease composition representing the temperature at which the ﬁrst drop of material falls from the test cup;that temperature being the average of the thermometer readings of the sample and bath.3.2.1.1Discussion—In the normal and proper operation of this test method the temperature of the interior of the grease test cup and the temperature of the oil bath are monitored simultaneously as the bath is heated.When theﬁrst drop of material falls from the cup,the temperature of the grease test cup and the bath temperature are averaged and recorded as the result of the test.4.Summary of Test Method4.1A sample of lubricating grease contained in a cup suspended in a test tube is heated in an oil bath at a prescribed rate.The temperature at which material falls from the hole in the bottom of the cup is averaged with the temperature of the oil bath and recorded as the dropping point of the grease.1This test method is under the jurisdiction of ASTM Committee D02onPetroleum Products and Lubricants and is the direct responsibility of SubcommitteeD02.G0.03on Physical Tests.Current edition approved April15,2009.Published July2009.Originallyapproved st previous edition approved in2002as D566–02.In the IP,this test method is under the jurisdiction of the StandardizationCommittee.This test method was adopted as a joint ASTM-IP standard in1964.This test method has been adopted for use by government agencies to replaceMethod1421of Federal Test Method Standard No.791b.2For referenced ASTM standards,visit the ASTM website,,orcontact ASTM Customer Service at service@.For Annual Book of ASTMStandards volume information,refer to the standard’s Document Summary page onthe ASTM website.Copyright©ASTM International,100Barr Harbor Drive,PO Box C700,West Conshohocken,PA19428-2959,United States.5.Signiﬁcance and Use5.1In general,the dropping point is the temperature at which the grease passes from a semisolid to a liquid state under the conditions of test.This change in state is typical of greases containing as thickeners soaps of conventional types.Greases containing as thickeners materials other than conventional soaps can,without change in state,separate oil.This test method is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control.The results are considered to have only limited signiﬁcance with respect to service performance as dropping point is a static test.N OTE 1—Cooperative testing indicates that in general,dropping points by Test Method D 5663and Test Method D 2265are in agreement.In cases where results differ,there is no known signiﬁcance.However,agreement between producer and consumer as to the test method used is advisable.6.Apparatus6.1Grease Cup —A chromium-plated brass cup conforming to the dimensions shown in Fig.1.6.2Test Tube —A test tube of heat-resistant glass,4with rim,100to 103mm in length and 11.1to 12.7mm in inside diameter provided with three indentations about 19mm from the bottom,equally spaced on the circumference.The depth of these indentations shall be such as to support the grease cup at about the point shown in Fig.2.6.3Thermometers ,two,having ranges as shown below and conforming to the requirements prescribed in Speciﬁcation E 1:Thermometer Number Temperature Range ASTM IP −5to +300°C2C 62C6.4Accessories —A stirred oil bath consisting of a 400-mLbeaker,a ring stand and ring for support of the oil bath,clamps for thermometers,two corks as illustrated in Fig.2,a polished metal rod 1.2to 1.6mm in diameter and 150to 152mm in length (Fig.3),a cup plug gage and thermometer depth gage,both shown in Fig.1.(Warning —The ﬂuid for the oil bath must have a ﬂash point in excess of the maximum temperature at which the bath is to be used 5and allowance must be made for thermal expansion to prevent overﬂow.Heating is prefer-ably done by an immersed electrical-resistance heater regulated by voltage control.An open ﬂame must not be used as the heating source.)(Warning —When a hot plate is used,care must be taken to avoid spilling oil on the hot surface.)7.Sampling7.1When ready to test,examine the sample for any indica-tion of non-homogeneity such as oil separation,phase changes,or gross contamination.When any abnormal conditions are noted,obtain a new sample.8.Preparation of Apparatus8.1Thoroughly clean the cup and test tube with mineral spirits conforming to Speciﬁcation D 235.(Warning —Flammable.Vapor harmful.)8.2Use only cups that are clean and free from any residue from previous runs.When the interior plating of the cup shows indications of wear,discard.8.3When new cups are to be used,check their dimensions by using the cup plug gage (Fig.1).To check the bottom opening a 2.72-mm rod should ﬁt easily while a 2.82-mm rod should not.6If the hole is undersized,ream to correct size.If too large,discard.3Supporting data have been ﬁled at ASTM International Headquarters and may be obtained by requesting Research Report RR:D02-1164.4Borosilicate glass has been found satisfactory for this purpose.5Dow Corning 710Fluid has been found satisfactory when bath temperatures as high as 288°C are required.Dow Corning is a registered trademark of the Dow Corning Corp.,Midland,MI 48686.6These are commonly available as a 7⁄64-in.drill and a No.34drill,respectively.N OTE 1—Dimensions in millimetres.FIG.1Plug Gage,Depth Gage,and GreaseCup8.4Test tube shall be clean and free of residues.Inspect the tube for evidence of chipping or cracking,particularly the points of indentation.Replace when necessary.8.5Inspect both cork ring guide and upper cork for charring or distortions in shape.Total clearance between the cork ring guide and the inside wall of the test tube is 1.5mm.When either cork is abnormal,replace.8.6Inspect the bulb end of the thermometer to be used in the test tube.Clean if there is any residue build-up.9.Procedure9.1Fill a test cup with sample by pressing the larger opening into the grease to be tested until the cup is ﬁlled.Remove excess grease with a spatula.Gently press the cup,held in a vertical position with the smaller opening at the bottom,down over the metal rod until the latter protrudes about 25mm.Press the rod against the cup in such a manner that the rod makes contact at both upper and lower peripheries of the cup.Maintain this contact,rotating the cup on the rod along the index ﬁnger to give a spiral-like motion down the rod to remove a conical section of the grease which adheres along the rod.As the cup approaches the end of the rod,carefully slip the rod out of the cup so that a smooth ﬁlm,free of air bubbles and of reproducible thickness,remains inside the cup.See Fig.4.9.2Place the corks on the thermometer to be used in the test tube as shown in Fig.2.With the thermometer depth gage in position in the test tube,adjust the position of the upper cork onthe thermometer so that the thermometer bulb bottoms snugly in the depth gage.Observe the relative position of the top edge of the upper cork to the thermometer stem as well as the relative position of the top edge of the test tube to the cork.Care must be taken to be certain that the thermometer is inserted to the same depth when the apparatus is reassembled with the grease cup in position.9.3Replace the depth gage with the grease cup as shown in Fig.2so that the thermometer is inserted to the previously gaged depth.When properly inserted,the bulb of the thermom-eter does not touch either the grease sample or the cup.9.4Suspend the test tube in the oil bath to a depth corresponding to the 76mm immersion mark on the thermom-eter.This should leave the test tube rim at least 6mm above the oil level.9.5Suspend the second thermometer in the oil bath so that its bulb is at approximately the same level as the bulb of the test tube thermometer.9.6Stir the oil bath and heat at a rate of 4to 7°C/min until the bath reaches a temperature of approximately 17°C below the expected dropping point of the grease.At this point reduce the rate of heating so that the temperature difference between the test tube and the oil bath is maintained between 1and 2°C.This condition is established when the oil bath is heated at a rate of about 1to 1.5°C/min.As the temperature increases,material will gradually protrude through the oriﬁce oftheN OTE 1—Dimensions in millimetres.FIG.2AssembledApparatusN OTE 1—Dimensions in millimetres.FIG.3Polished MetalRodgrease cup.When a drop of material falls,note the tempera-tures on the two thermometers and record their average to the nearest degree as the dropping point of the grease.N OTE 2—Certain greases form a drop with a tailing thread upon melting,which can break off or which can hold until the drop reaches the bottom of the test tube;in any case,the observed dropping point is the temperature when the drop reaches the bottom of the test tube.N OTE 3—The dropping points of some greases,particularly those containing simple aluminum soaps,are known to decrease upon aging,the change being much greater than the deviation permitted in results obtained by different laboratories.Therefore,comparative tests between laborato-ries should be made within a period of six days.9.7Two determinations can be made simultaneously in the same bath,provided both samples have approximately the same dropping points.10.Report10.1Report the result to the nearest degree as the ASTM-IP dropping point,ASTM D566.11.Precision and Bias 711.1Precision —The precision of this test method as deter-mined by statistical examination of interlaboratory results is as follows:11.1.1Repeatability —The difference between two test re-sults obtained by the same operator with the same apparatus under constant operating conditions on identical test material would,in the long run,in the normal and correct operation of the test method,exceed the following value only in one case in twenty:Repeatability 57°C(1)11.1.2Reproducibility —The difference between two single and independent results obtained by different operators work-ing in different laboratories on identical test material would,in the long run,in the normal and correct operation of the test method,exceed the following value in only one case in twenty:Reproducibility 513°C(2)N OTE 4—Although the cooperative data does show that precision varied considerably with dropping point range,a statistical analysis of the composite of the cooperative data was used to generate the precision statement.This test data is given in the article “Report of ASTM Technical Committee G on Dropping Point Methods for Lubricating Grease”by P.R.McCarthy appearing in the NLGI Spokesman,V ol 31,1967,page 76.11.1.3Bias —There is no bias in this test method because the value of the dropping point can be deﬁned only in terms of the test method.12.Keywords12.1dropping point;grease;lubricating grease7There is no research report on ﬁle because this test method was developed prior to the development of Research Report guidelines.The statistical method used to determine precision isunknown.FIG.4Procedure to FillCupASTM International takes no position respecting the validity of any patent rights asserted in connection with any item

Materials,Revisions F (23) Hardware Overview 1Hardware OverviewThe PPCMB provides control signals and audio signals to the DUT.The PPC sends the control signals to the TAS1020B device through the USB human-interface device(HID)protocol.The TAS1020B deviceconverts to I2C and sends to the appropriate I2C address.The audio signals are provided through USB audio,SPDIF,or analog signals.The aforementioned signals are converted to I2S–see Figure2.Figure1.PurePath Console Motherboard Revision D3 SLOU366B–June2013–Revised February2015TMHardware Overview Figure2shows the PPCMB Revisions D and E signal flow.For Revision F,refer to the block diagram in Section4.5.Figure2.PurePath Console Motherboard Signal Flow(Revisions D and E)1.1PurePath Console Motherboard Features•The PPC sends I2C control signals through the USB link:the initialization sequence is sent utilizing auto DUT detection reducing hardware setup time•Three I2S audio sources:USB audio,SPDIF,and ADC•Audio processing:TLV320AIC3262(mini-DSP)•Dual asynchronous sample-rate converters(ASRC)PWM modulator:TAS5548•Interface with PurePath Smart Amp and audio devices designed for use in TV,mini-component,AVR application1.2PurePath Console Motherboard FunctionsThe PPCMB is organized into two sections:control data and audio data.Control data is routed through the I2C bus and audio data is routed through the I2S bus.An analog signal can also be routed directly to and from the DUT.The control data is sent from the PPC through the TAS1020B USB to I2C commands.The MPS430™microcontroller can also be used independent of the PC host.The MSP430device is used for stand-alone demonstrations;therefore,it is configured for each application. Hardware Overview The digital audio data input is selectable from USB audio,optical SPDIF,coaxial SPDIF,and analog ADC.When a digital audio data input is selected,the PPC will automatically send appropriate scripts to thedevice in-use.When direct audio analog input is required,the PPCMB will provide this signal through a line-in connector.•TLV320AIC3262(mini-DSP)provides programmable algorithms and audio post-processing for many applications•PWM modulator with dual ASRC and post-processing capability can be used in mini-component or AVR systems.The PWM output is connected directly to TI's high-power(300W)amplifier TAS5624AEVM.•I2S audio from the DUT can be captured through the USB link or optical SPDIF for signal analysis1.3PurePath Console Motherboard Detailed OperationsThe following information can be used as a debugging guide.Upon power-on,the PPCMB uses optical SPDIF input(default).The I2S signals can be seen with anoscilloscope probe at the pin headers LRCLK,SCLK,SDIN,and MCLK.EEPROM1(EP1)is flashed with firmware that runs the TAS1020B for the USB audio(USB-miniEVM), HID,and the USB composite device.Figure3shows the Device Manager.Figure3.Device ManagerWhen the PPCMB is plugged in to a PC,the Device Manager should show all of the USB devices shown in Figure3.If one of the devices does not show up,the PPCMB will not work correctly.When the PPC is executed,the PPC uses the USB audio as the default I2S input.The PCM9211acts as the multiplexor that selects among the following I2S signal sources:optical SPDIF,coaxial SPDIF,andUSB audio.The output of the PCM9211device is routed to the TLV320AIC3262device.The signal from the TLV320AIC3262is then routed to the TAS5548device and the output connector(J1).TheTLV320AIC3262can be bypassed by switching the MUX3select control signal to high and the MUX4,MUX5,and MUX6select control signals to low by using the PPC;and adding jumpers between pins1and 2of the header LRCLK,SCLK,SDIN,and MCLK pins.5 SLOU366B–June2013–Revised February2015TMMicro USB24VDCPSU ANALOGINEXT I2SThe I 2S header pins are used for three purposes:probing I 2S signals coming out of PCM9211,bypassing I 2S signals from TLV320AIC3262and using the PCM9211I 2S signals,and bypassing I 2S signals from the TLV320AIC3262and using an external I 2S source.The TAS5548device is used for PWM input devices such as the TAS5624.The TAS5548is TI's latest 8-channel PWM modulator and has dual ASRC with audio post processing.For more information go to /product/TAS5548.The PCM3168A takes analog inputs (AIN1and AIN2)and routes them to the TLV320AIC3262.AIN1is converted to I 2S and routed to TAS5548and J1.The analog switch,MUX2,routes analog input directly to DUT through J1.The GPIO extender (TCA6424A –U8)is used for initialization of the multiplexors and discrete signals.It is controlled from the PPC through the I 2C.The MSP430is populated but is not programmed.It is used in place of a PC for specifically-designed demonstrations using a combination of TI devices on the PPCMB and a DUT evaluation board or reference boards.2PurePath Console Motherboard Setup and Software InstallationThis section describes the PPCMB setup and software installation.Since the PPCMB connects to one of the DUT EVMs,it is necessary to show the connection in this section.The TAS5760xEVM is used for this purpose.2.1PurePath Console Motherboard SetupFigure 4shows the PPCMB connection.Figure 4.PurePath Console Motherboard ConnectionThe hardware requirements are listed as:•Desktop or laptop PC running either Windows®XP or Windows7•DUT EVM such as TAS5760xEVM;It is used here as an example•Power supply24VDC•Speakers and cables•A USB micro type B cable•Audio source:this can be a DVD player with appropriate SPDIF cable or Windows Media Player from Windows XP or Windows7For hardware setup,follow these steps:Step1.Plug in the USB cable from the PC to the PPCMB;the USB Lock LED(blue)is illuminatedStep2.Connect the PPCMB to the DUT EVM,in this case the TAS5760xEVMStep3.Connect the PSU to DUT EVM and turn on the power.5-V and3.3-V LEDs are illuminatedStep4.If an optical SPDIF source is used,the blue SPDIF clock-locked LED is illuminatedStep5.Disregard the orange LED indicating the energy threshold(ET)level is exceeded.The ET value must be cleared for the orange LED to be extinguished.2.2Software InstallationDownload the PPC from the TI Web site(/tool/purepathconsole).The TI Web site has thelatest release of the GUI.Execute the GUI installation
