UDS2100 Device Server User Guide
72
This chapter discusses how you can diagnose and fix errors quickly without
having to contact a dealer or Lantronix. It helps to connect a terminal to the serial
port while diagnosing an error to view summary messages that may display.
When troubleshooting, always ensure that the physical connections (power
cable, network cable, and serial cable) are secure.
Note:
Some unexplained errors might be caused by duplicate IP addresses on
the network. Make sure that your unit's IP address is unique.
When troubleshooting the following problems, make sure that the UDS2100 is
powered up. Confirm that you are using a good network connection.
