This section contains information on the cable and pin assignments for the
ProLinx module's serial ports (RS-232/422/485) and the application port.
The ProLinx module will come with one to five serial ports, depending on the
configuration purchased. In all cases, the protocol serial ports will have the same
pin-outs.
Example: The 5602-RIO-MCM4 module contains five serial communication ports: four
configurable Modbus ports and a Configuration/ Debug port.
The 5601-RIO-MCM module contains two serial communication ports: one configurable Modbus
port and a Configuration/Debug port.
Each serial port is a Mini-DIN physical connection. A 6-inch "Mini-DIN to DB-9M"
cable is provided for each active protocol port. The DB-9M provides connections
for RS-232, RS-422 and RS-485. The diagrams in the following topics detail the
pin assignments for several possible physical connections.
