COM Port Interface Cable

The COM port connects to either a PC or to an ASCII terminal or printer for
alarms. The COM port-to-PC cable is a 14-foot, 26 AWG, 8-conductor cable with
an 8-position modular plug keyed connector and a DB9 socket connector
(Figure C-3). The COM port connector is an 8-position keyed modular jack
(Table C-3). The data signals on this port are referenced to a DTE interface.
