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 G for details).
Most standard external PC modems can be usd with the M4RTU/M4 I/O. However, a custom (or special)
communications cable must be used between the modem and the M4RTU/M4 I/O. Wiring diagrams for this
cable are shown below:
