The terminal ports on the TX102 have RJ-45 module connectors.
Most serial computers, terminals, and printers do not have RJ-45
modular connectors. Therefore, adapters are required to convert
either DB-25 or DE-9 connectors to modular connectors. BayTech
has a complete line of RJ-45 adapters and cables that will make your
installation quick and trouble free. The TX102's terminal port use the
following signals for communication:
