#1 – ESR90x ONLYPair mode with client in data arrival and clientHB/no HB setting connects on power and shouldnot. This happens only if the COM portsconnected to client and server are left open.If you hit <Update> in Vlinx, it powers up anddoes not connect as expected. For ESR901 only,the terminal block passes and the DB9 fails.

Note ESP90x does not have this bug.

#2Pair mode with client in data arrival, client HB/noHB, client & server serial timeout = 0, and client& server TCP timeout = 0 settings does not receivedata consistantly in terms of sizes of data sent(see tables below). This was tested on and off thenetwork for ESR901 with same results. ESR902and ESR904 tested off the network. Work around – For ALL ESR901/902/904Setting server or client serial/TCP timeout = xxseems to help. First initial attempt will fail, thensubsequential try after timeouts has expire will besuccessful. Up to 20K bytes was tested successfully.

#3Windows NT – SHLWAPI.dll files are found to bemissing in some service packs. The installation will gothrough fine. The error will occur when you run theVlinx software and do not have this file in the properdirectory.Work around – Copy this file from somewhere into theproper directory.

#4Fresh factory unit or when set to "default“ONLY in Vlinx (web, Telnet, console defaulting isok), port 1displays "RS-232", but actually isoperating at console mode.

Work around – hit <Update> in Vlinx or <Save> in web,telnet or console, everything will be okay. Anotheralternative is to use default in web, Telnet or consoleonly. Note that hitting reset on the unit does not fix it.

ESP90x Common Q/AV1.00

Same as last training, left for reference only. No training required.

Basic Troubleshooting1. Find the device with Vlinx software2. Setup an appropriate IP address for user’s LAN3. Create a virtual COM port4. Ping the device on the LAN5. Telnet to the device via the IP address setup and port 236. Access the VCOM from a terminal emulation program(Comtest, hyperterminal, etc).Loopback data through thedevice using VCOM or Telnet (IP & port number)

Q/A #1 Can’t find device with Vlinx software1. May be in different subnet2. May be going through router between the PC and ESP90x/ESR90x3. Check LED status (Power LED solid, Link LED solid, Ready LED blinking)4. Disconnect all DB9 port(s)5. Check network cables6. Reset the device by pushing the indented button with pencil/pen7. Repower the device by removing power and reapplying8. Try connecting directly to the Vlinx with a network cross-over cable

Q/A #2 Setup an appropriate IP address for the device1. The assigned IP address must conform to the user’s local network2. If 255.255.255.0 is used for Netmask, the first 3 sets of digits must match for the PC and ESP90x/ESR90x device3. Be sure the user click on the <Upgrade> button or <Save> in the config screen to save the IP address changes

Q/A #3 Creating VCOM1. If Vlinx software can find the device, the user should be able to setup VCOM2. The created VCOM port should show up in Window’s device manager3. Check the port number used (default is 4000, DO NOT USE 5300, 8888, 8889, or 8890 as these are used by the unit for monitor and control)

Q/A #4 Pinging the device1. If there is no ping, check the IP address again2. Check the IP address of the sending PC (go to DOS prompt and type in “ipconfig” for Win 2K/XP)3. Check the Link LED (should be solid)

Q/A #5 Telnet to the device1. Make sure the dipswitches are DOWN or OFF so that it is NOT in console mode2. Be sure also that the software selected mode is also NOT in console mode

Q/A #6 Access the COM port1. Should be able to open the COM port using Hyperterminal, Comtest, etc2. If no connection, check the remote IP and be sure it is “255.255.255.255” for full access by any IP address

Q/A #7 Loopback using VCOM or Telnet1. If no loopback, check the flow control (NONE for loopback test)2. Check baudrate used3. Try loopback using telnet (IP and port number) or Hyperterminal Winsock (IP and port number)

Q/A #8 LEDSPower LEDSolid ON when power apply

Link LEDSolid ON when Ethernet LAN connected (blinking with data)-green = 100Mbpsyellow = 10Mbps flashing = error

Ready LEDBlinking for normal operation (failure otherwise)

Q/A #9 DipswitchesUnit Dipswitches Operation

ESP901 3 All ON or up = console mode (9600 8-N-1)All OFF or down = run or normal mode

ESP902 3 All ON or up = console mode (9600 8-N-1)All OFF or down = run or normal mode

ESP904 0 Fully software selectable

ESR901 2 #1 ON or up = console mode (9600 8-N-1)#1 OFF or down = run or normal mode#2 ON or up = terminal block mode#2 OFF or down = DB9 mode

ESR902 1 ON or up = console mode (9600 8-N-1)OFF or down = run or normal mode

ESR904 1 ON or up = console mode (9600 8-N-1)OFF or down = run or normal mode

Q/A #10 Port Information – They must be open inthe firewall for correct operations.

Port Use/Control

5300 Heartbeat & configuration setting in TCP mode (i.e. pair tunneling mode)

8888 Vlinx update

8889 Configuration setting in UDP mode

8890 Vlinx monitor

Q/A #11 Keep loosing connection to the ESP90x.Keeps dropping off the network.

If we can ping or Telnet to the unit, the unit is not dead. If ping fails, check ESP90x menu to seeif the unit is setup in a communication mode of RS-232, RS-422 or RS-485. If working withESP901 or ESP902, all switches on the unit should be in the down position. If working withESR90x, the console dipswitch should be in the down position.

Please use Vlinx management software to search for ESP90x units. Note that the search featureuses UDP broadcast packets which confines the search to the local LAN or on 1 side of arouter/gateway. If the unit is located outside the LAN, he should use specified IP address to reachthe unit.

If the IP address conflict with other device in the LAN, it will fail to reach the unit. To check forduplicate IP addresses, remove the ESP90x from the LAN and ping the ESP90x address. If youreceive a response, there is another unit on the LAN with the same IP address.

A software reset from the Telnet session should make the unit available for a new client connection. If the unit neither can be pinged nor Telnet, the unit maybe dead (if the green READY LED is notblinking) or the network is broken (if the LINK LED is not ON). A hard power cycle will be necessary.Please fill out “ESP ESR Support Template Vx.xx” to capture the customer’s setup for further support.

Q/A #12 How do I access the device from outside thelocal LAN.

There are many exceptions to this procedure. Normally, the ESP90x needs tohave what is called a public IP address. By public, this means that no once elsein the world can use this. For example, at B&B, a governing organization hasassigned us public IP addresses using 12.32.1xx.xxx IP address.

From the outside location, first ping the unit’s IP address, then Telnet to themenu. If both failed, there is a good chance the Network Administrator hasthe firewall blocking communications.

At this point, please talk to the Network Administrator to inform him of yourlack of communications. He should be able to help open TCP IP address, port#, Telnet port #23, and the ping port #.

It is very important that the user puts in the correct IP address for the Gatewayunder configuration pertaining to the their LAN.

Q/A #13 VCOM has been installed and hyperterminalor similar serial program has confirmed that loopbackworks. However, the customer’s software still does notsee this VCOM.

Please check that their software can access as high ofCOM number as the VCOM has been setup (i.e. VCOM20 or whatever). Otherwise, we may have to lower thisVCOM number to a range the software can handle.

Note that Hyperterminal can ONLY access limited portnumber ranges.

When should it be used?

1. Try basic troubleshooting.2. Try the Common Q/A.3. Verbal conversation and troubleshooting.4. Use support template and turn over to engineering.
