How can you change the configuration of the Momentum CPU Serial port 1 from RS485 to RS232?
When I try to change the Serial Port on the Momentum CPU from RS485 to RS232, the configuration is grayed out in Control Expert (Unity Pro).
Control Expert v14
Unity Pro XL V13
The serial port can not be changed from RS485 to RS232.
Serial Channel 1 on the Momentum CPU modules 171 CBU 78090, 171 CBU 98090 and 171 CBU 98091 is a static RS485 port.
It is not configurable to be used with RS232.
