they do not appear to be communicating

are configured or automatically obtained
2 Ensure the Local Port setting on each unit
matches the Remote Port on the other unit
I’m trying to connect my serial device to
my PC over the LAN/WAN
You need to use Com Port Redirector software on
your PC and the ComPort Control Connection Con-
trol setting for the Precidia unit.
What are the pinouts for the unit? See “Cables” on page E-1.
The unit is not connecting to the net-
work
Ensure the IP Address, Subnet Mask, and Gateway
are correctly configured. This can be done manu-
ally, or through a DHCP server.
The unit is not communicating with the
serial device
1 Ensure all cables are properly connected
2 Ensure the proper cable is used. Modems and
some POS terminals require a specialized null
modem cable. See “Specialized Null Modem
Serial Cable” on page E-1.
3 Ensure you have a configured a Protocol for the
Serial Port and any other necessary settings
I lost the Console Password and I cannot
