11: Troubleshooting and Contact Information Problem/Message The device server is not communicating with the serial device to which it is attached. Reason The most likely reason is the wrong serial settings were chosen. Solution The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS-232, 9600 baud, 8 character bits, no parity, 1 stop bit, no flow control. When you try to enter the setup mode on the device server using the serial port, you get no response. The issue is most likely something covered in the previous problem, or possibly, you have Caps Lock on. Double-check everything in the problem above. Confirm that Caps Lock is not on. You can ping the device server, but not Telnet to the device server on port 9999. There may be an IP address conflict on your network You are not Telneting to port 9999. The Telnet configuration port (9999) is disabled within the device server security settings. Turn the device server off and then issue the following commands at the DOS prompt of your computer: ARP -D X.X.X.X (X.X.X.X is the IP of the device server). PING X.X.X.X (X.X.X.X is the IP of the device server). If you get a response, then there is a duplicate IP address on the network. If you do not get a response, use the serial port to verify that Telnet is not disabled. With DeviceInstaller, you get the "Wrong Password" error when you try to upgrade the firmware. The file you are attempting to load is the incorrect firmware file for the UDS. Download the correct firmware file from the Lantronix website. The device server appears to be set up correctly, but you are not communicating with your device attached to the device server across the network. If you are sure that the serial port setting is correct, then you may not be connecting to the correct socket of the device server. Another possibility is that the device server is not set up correctly to make a good socket connection to the network. Use the Connect Mode option C0 for making a connection to the UDS from the network. Use Connect Mode option C1 or C5 for a connection to the network from the UDS. When connecting to the Web Manager within the device server, the "No Connection With The Device Server" message displays. Your computer is not able to connect to port 30718 (77FEh) on the device server. Make sure that port 30718 (77FEh) is not blocked with any router that you are using on the network. Also, make sure that port 77FEh is not disabled within the Security settings of the device server. UDS2100 User Guide 70
