Portbase User Guide
43
Portbase’s IP address can change. Either configure your DHCP server to give Portbase a
permanent lease, or configure Portbase to be on a STATIC IP address outside the scope of the
DHCP addresses.
z The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP
address is correctly loaded into Portbase (via the displayed or printed configuration 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 loading procedure was properly executed.
z Also verify that the host computer and Portbase are using the same subnet masks(for example, if
Portbase has a subnet mask of 255.255.255.0, the host must have the same subnet mask) or that
the router is properly configured to pass data between the two devices.
z If the wrong IP address is loaded, check your network for DHCP server, and make sure that the
server is not set up to load wrong IP addresses into Portbase.
ƒ Troubleshooting Windows Problems
z If you are having trouble accessing the connected serial device through Windows, ensure you
can ping Portbase using the command PING x.x.x.x, where x.x.x.x is the IP address of Portbase.
If you cannot ping Portbase, you will not be able to access the serial device.
z If you are running COM port redirector and the software reports an error, verify that the 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.
