Using an Xdriver on comm4 of a CX 9200 may not work

Issue

CX 9200 comm4 has 5 wires instead of 3, so the wires have to be jumpered to work with RS-485

Environment

CX 9200

Xdriver

Cause

The issue with comm4 is that it is a 4 wire RS-485 interface and the xdriver ends up attempting to decode its own messages

Resolution

Sometimes this scenario will work, but other times values do not come across properly. Alternatives for this would be: 

  1. Use a media converter which may do a better job of jumpering the signal
  2. Move the xdriver to a different port
