- Links the PLC-3/10 processor to remote 1771 I/O chassis through assigned scanner channels
- Allows one channel to serve RS-232-C communications when the remaining channels are reserved for I/O
- Requires the original channel mode, rack assignments, backup path, and peer-communication layout to be restored
