2.2.3 Attaching a Customer-Supplied COM Module to the OMU1-S-RF
A fully isolated external communications board (i.e. Wireless or PLC module) may be attached to the
OMU1-S-RF’s UART cable without using the UART-ISO daughter board. The OMU1-S-RF UART cable
supplies 100 ma max at +3.3 V.
The OMU1-S-RF UART cable pin assignments are as follows:
The OMU1-S-RF UART cable does not support 1.8V signal levels.
