G4LC32ISA-LT User’s Guide

Wiring to a Modem (A DCE Device)

Refer to your modem documentation for detailed wiring information, possible jumper configuration,
and initialization setup. You may also wish to refer to Opto 22’s communication application notes,
available through Opto 22’s Bulletin Board Service (see Appendix E for details).

Most standard external PC modems can be usd with the G4LC32ISA-LT. However, a custom (or
special) communications cable must be used between the modem and the G4LC32ISA-LT. Wiring
diagrams for this cable are shown below:
