To connect remote I/O cable, do the following:

1. Run the cable (1770-CD) 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 signal conductor with clear insulation to the 3-pin connector terminal labeled 2.

4. Connect the shield drain wire to the 3-pin terminal labeled SH. 5. Tie wrap the remote I/O network cable to the chassis to relieve strain on the cable.

   Once you connect the programming device through a local DH+ link to one processor, the device can communicate with any PLC-5/VME processor on the link. You can also communicate with PLC-2, PLC-3, and PLC-5/250 processors connected to the link provided you have the appropriate programming software installed. The processor has electrically parallel DH+ connectors.

   PLC-5/V40B

   PLC-5/V80B

• 8-pin connector for each of channel 1A and 2A

• 3-pin connector on each of channel 1A and 2A

• Channels 1A and 2A must be configured to support DH+ communication to use the connectors described above. Note that Channel 1A's default configuration is DH+ communication.

• Channels 1B and 2B can also support DH+ communication if properly configured, but they do not have parallel connectors.
