or hardware handshaking. This cable works with any RoHS DB25 serial port. This cable works
with either an AD278A connector or an AD281A port module.
Table B-5
lists the pin-out connection between the DB25 adapter and the DB25 terminal/printer
with software or hardware handshaking.

DB-25 Modem Cable
To connect a DB-25 equipped asynchronous adapter to a modem, use a standard straight-through
cable. A straight-through cable must have a DB-25 female connector at the AD278A fan-out end
or the AD281A port module end, and a DB-25 male connector at the modem end. All 25 pins are
connected, 1 to 1, 2 to 2, 3 to 3 and so on. Use a shielded cable, and connect pin 1 of each connector
to the cable shield.
RS-232 Asynchronous: RJ-45
This section provides the pin diagram for RJ-45 cable.
