To connect remote I/O cable:
1. Run the 1770CD cable from the processor to
each remote I/O adapter module or processor in
the remote I/O system.
2. Connect the signal conductor with blue insulation
to the 3pin connector terminal labeled 1 on the
processor and to each remote I/O adapter module
(or PLC5 adapter) in the remote I/O system.
3. Connect the shield drain wire to the center
terminal of the 3pin connector.
4. Connect the signal conductor with clear insulation
to the 3pin connector terminal labeled 2.
5. Tie wrap the remote I/O network cable to the
chassis to relieve strain on the cable.
6. Terminate the remote I/O link by connecting an
external terminator resistor between the remote
I/O terminals labeled 1 and 2.

You can install a remote I/O link two ways:
• trunk cable / drop cablefrom the drop cable to the connector screw terminals on the remote I/O connectors of the processor
• daisy chainto the connector screw terminals on the remote I/O connectors of the processor and then to the remote I/O screw
terminals of the next remote I/O device
