Insert the upper end of theDIN-Rail clip into the back ofthe DIN-Rail track from itsupper side2. Lightly push the bottom of theDIN-Rail clip into the track.3. Check if the DIN-Rail clip istightly attached to the track.4. To remove the JetCon3701GP-U from the track,reverse the steps above.4. System ConfigurationThe JetCon 3701GP-U provides Ethernet signal transfer function fromelectrical to optical and various packet handling and cable diagnostic features.In this chapter, we will introduce how to configure those functions and benefits as following topics.4-1. Quality of Service (QoS)4-2. Packet filtering4-2. Link Loss Forwarding (LLF)4-3. Event Alarm Relay Configuration4-1. Quality of ServiceThe JetCon 3701GP-U supports 2 types of priority mechanisms - IEEE802.1Q priority tag based CoS and ToS of IPv4. All the packets will be examined andforwarding into high or low priority queues. The Quality of Service function is pre-configured as enabled.The weight round robin (WRR) ratio of high/low queue is 8:1. After 8 high priority packets were progressed then 1 low priority packets.IEEE 802.1Q tag-based CoSThe JetCon 3701GP-U will examine the 3 bits of priority field carried by a VLAN tag and map it to the corresponding priority. A packet with priority field ranging from 0 to 3 will be treated as a low priority packet and will be stored in low priority queue. A packet with priority field ranging from 4 to 7 will be treated as a high priority packet, and will be stored in high priority queryIEEE 802.1Q Type of Service for IPv4 /IPv6 packetJetCon 3701GP-U provides the IP layer ToS function by recognizing the priority octet and mapping it to the corresponding priority. For an IPv4 packet, it is embedded in the TOS (type of Service) Octet. For an IPv6 data packet, the Traffic Class Octet is used to differentiate the Class of Service. When this function is enabled, the JetCon 3701GP-U will automatically recognize the IP version and capture the either the TOS field (IPv4) or Traffic Class field (IPv6).4-2. Packet FilteringTo prevent broadcast packet flooding on the network, the JetCon 3701GP-U have implemented broadcast packet control function. The port begins to drop incoming broadcast packets if the received broadcast packet counts reach the threshold as different link speed – 25Mbps at link speed 1000Mbps, 10Mbps at link speed100Mbps and 1Mbps at link speed 10Mbps.4-3. Link Loss Forwarding (L.L.F.)The Link Loss Forwarding provides a real time hardware-based network activated diagnostics mechanism. In usually, the Gigabit Media Converter on the end offiber cable should be equipped LLF function to provide better networkperformance and reduce the maintenance cost.The JetCon 3701GP-U provides 2-way Link Loss Forwarding function. Aboutthe Link Loss Forwarding behaviors are described in following, please refer it.Gigabit FiberGigabit Copper Gigabit Copper Node A Node BIn the above diagram includes node A, B and converter A,B. Both of converters linked with Gigabit fiber. In traditional fiber network architecture; if the Gigabitcopper of node A link down, the node B will not have any information, just packet can’t forward between A and B.With the Link Loss Forwarding feature, the link down event of node A will forward to converter A and B. Therefore, converter A will turn off the fiber signal andconverter B will turn off Gigabit copper signal to inform node B that port link down event occurred until the node A port recovery. In some application, you also can obtain an event alarm signal by enable the port event alarm function. Please refer to the section 4-4.The following procedures will introduce how to configure LLF function.Step 1: power on the device A, B and connect the fiber and copper ports.Step 2: Ensure the port link LEDs is working exactly.Step 3: if the port link event occurred, the other port will be trigger and turn off by the LLF mechanism.Step 4: To start the transmission and retrieve the L.L.F. function, the LLFDipswitch should be reset again.4-4. Event Alarm Relay ConfigurationThe connection of Event Alarm Relay already described in section 2-5 Connect the Dry Relay output and this section will introduce how to enable it5. System Installation.5-1. Installation and Testing1. Take out your JetCon 3701GP-U Industrial Gigabit Media Converterfrom the package box.2. Check if the DIN-Rail clip is attached to the JetCon 3701GP-U. If the DIN-Railclip is not attached to the JetCon 3701GP-U, refer to DIN-Rail Mounting section for DIN-Rail installation.3. To place the JetCon 3701GP-U on the DIN-Rail track or wall, refer to theMounting Installation section.4. Pull the terminal blocks off the JetCon 3701GP-U and wire the power lines.Refer to the Wiring the DC Power Inputs section for how to wire the power inputs.5. PWR1 and PWR2 dual power inputs can be connected to power sourcessimultaneously. When the primary power source fails (the default setting is PWR1), the system will automatically switch to the secondary power source (PWR2), preventing any power interruption.Both of Power 1 and Power 2 support positive electricity electricity powersystem. Please notice the power system for power 1 and power 2 only acceptpositive electricity power system at one time6. Check the LEDs of PWR1 and PWR2 to make sure that JetCon 3710GP-U isoperating normally.7. Use Category 5e straight through Ethernet cables with RJ-45 connectors toconnect network devices.8. Connect one side of an Ethernet cable with a RJ-45 connector to the JetCon3701GP-U’s Ethernet port (RJ-45 port), and the other side of the fiber cable to the n etwork device’s Gigabit fiber port.If you want to connect with Gigabit Fiber, please install appropriate SFP fiber transceiver and fiber cable. To ensure the connection is working, please notice the type of fiber transceiver of JetCon 3701GP-U’s and the other end ofdevice.9. Check the LED indicator of port status (blinking green) on the JetCon 3701GP-U to see if the network connection is successfully established. Power on the PC host, activate the Command Line mode, and ping the connected Ethernet device to see if it responds.9.1 To enable the “Command Line mode”, click Run in the Start menu, typeCommand, and click OK to continue.10.10.1 T ype ping 192.168.1.1 command to check the connection. Here we use IPaddress 192.168.1.1 as an example. Before the testing, be sure your PChost and target device are in the same subnet.11. Power on the host, activate the Command Line mode, and ping the connectedEthernet device by typing “ping –t 192.168.1.1” command to see if it willrespond.12. The parameter-”t” allow you to continue to ping the network device, as shownin the figure below.Before you continue, make sure that both PWR1 and PWR2 are successfullyconnected to power sources. When PWR1 fails, the LED for PWR1 will go out. At that moment, if the ping command is still replying, then it proves that redundant power input function works normally.13. Exit the Command Line mode, and connect PWR1 power input. At this stage,your JetCon 3701GP-U has been tested and the installation is completed.6. Troubles shooting⏹Make sure you are using the correct DC power suppliers (DC44~57 V) orpower adapters.⏹Select Ethernet cables with specifications suitable for your applications to setup your systems. Ethernet cables a re categorized into unshielded twisted-pair(UTP) and shielded twisted-pair (STP) cables. Category 3, 4, 5 Ethernet cablesare suitable for systems with 10 Mbps transmission speed. For systems with100/1000 Mbps transmission speed, Category 5, 5e, 6 Ethernet cables are thesuitable specifications for this environment. Also make sure that the distancebetween each node cannot be longer than 100 meters (328 feet).⏹If the power LEDs goes off as the power cord plugged in, a power failure mightoccur.

Prevents electromagnetic interference problems, this is useful for applications in electromagnetically noisy environments such as processes involving powergenerators, motors, arc furnaces, induction heaters etc. Correctly wired grounds help cut down on electromagnetic interference. The 5 pin terminals allow a ground on the 5th pin of each block and a Functional earth connectionto the DIN rail.ES-571 Factory Floor ApplicationFactory floors can be harsh environments. Extreme temperatures can be gen-erated in the manufacturing process, machinery can be noisy and generateelectromagnetic interference and space is a premium. But engineers still needto be able to access and maintain equipment safely and without downtime. Asfactories expand and modernise older equipment and remote devices need tobe networked, but cabling can be expensive and impractical, especially overlarger areas.The ES-571 with total galvanic isolation has 1 serial port that is softwareselectable as either RS232, RS422 or RS485 and 2 Ethernet ports. The ‘EasyWire’ removable colour coded Screw T erminals Blocks are individually numberedfor simple fast, error free wiring. The slim ‘end on’ case with integral mount clipsstraight on to a DIN Rail. The ES-571 has an operating temperature range of-40ºC to +80ºC and +5VDC to +30VDC Dual input reverse polarity protectedpower supply.

To achieve good long distance noise immunity, 2 wires are used to carry each signal, configured as a twisted pair of cables. The TXD pair and RXD pair are used to carry the data whilst the RTS pair and CTS pair lines are used for handshaking. Thus 2 twisted pairs are used without handshaking and 4 twisted pair cable is used with handshaking both these schemes allow full duplex data communications.RS485 Standard: RS485, based on the RS422 standard allows up to 32 driver/receivers pairs on a standard load or 128 low load devices per port can be connected. Whilst only one of these should be transmitting data at any time, the rest can all simultaneously listen to the data. Handshaking is performed by software protocol. Two twisted pairs form a full duplex system. Often only one twisted pair cable is used as the TXD and RXD lines are tied together; this is known as half duplex mode. Brainboxes RS422/485 products implement a state of the art hardware autogating circuit ensuring error free communications in half duplex configurations.Industrial Ethernet to Serial RS485: recievers are 1/8th load allowing upto 256 nodes on the bus. Fail safe open circuit and short circuit protection, protects the Industrial Ethernet to Serial against wiring faults.Line Terminating Resistor: On board RS485 line termination resistor can be enabled by a user selectable jumper. The RS422/485 line terminating resister prevents signal reflections when the ES device is at the end of transmission line.Bias Resistors: On board RS485 Half Duplex fail safe bias resistors enabled by user selectable jumpers.
