SerialGate User Guide
104
The problem may be the result of mismatched or duplicate IP addresses. Verify that
the IP address is correctly loaded into SerialGate (via the displayed or printed configu
ration information or through the remote console), and make sure that no other nodes
on the network have this address (duplicate addresses are the biggest cause of TCP/
IP connectivity problems). If the IP address is not correct, then check whether the lo
ading procedure was properly executed.
Also verify that the host computer and SerialGate are using the same subnet masks(f
or example, if SerialGate has a subnet mask of 255.255.255.0, the host must have th
e same subnet mask) or that the router is properly configured to pass data between
the two devices.
If the wrong IP address is loaded, check your network for DHCP server, and make s
ure that the server is not set up to load wrong IP addresses into SerialGate.
Troubleshooting Windows Problems
If you are having trouble accessing the connected serial device through Windows, ens
ure you can ping SerialGate using the command PING x.x.x.x, where x.x.x.x is the IP
address of SerialGate. If you cannot ping SerialGate, you will not be able to access
the serial device.
If you are running COM port redirector and the software reports an error, verify that t
he correct virtual COM port is being used when the application runs. Verify that your
application’s COM port settings have been changed to use the virtual COM ports.
