Omega CNiS8DH, CNiS16 Wiring Outputs, RS-232 Output Wiring Hookup b RS-485 Output Wiring Hookup

2.3.5 Wiring Outputs (continued)

This device may also have a programmable communication output. The RS-232 and RS-485 Output Connection are shown below.

If your meter has the communication option, the internal excitation is not available. Use external excitation for strain gauge meter.

External RS-232 connections are not available with -EI or C4EI options.
