RS-232 Connections

Refer to the “Hardware Reference” chapter for the ION 7500 and ION 7600 meters’

RS-232 specifications.

An RS-232 connection is made at the male DB9 connector (COM1) at the back of the meter. The meter acts as a DTE device in all RS-232 connections. Use a null modem cable for connecting a meter to a workstation or use a standard straight- through RS-232 cable for connecting to an external modem. In either case, one end of the cable must be equipped with DB9 female connector for mating with the DB9 male connector on the meter. The maximum cable length is 50 feet (15.2 m).
