Wire the Connector for the Remote I/O Network
To wire the connector for the remote I/O network, refer to the Cabling and
Termination table and follow these steps.
1.
Connect Line 1 (blue) of the remote I/O cable to the lower pin on the
1756-RIO module.
2.
Connect the shield to the middle pin.
3.
Connect Line 2 (clear) of the remote I/O cable to the upper pin on the
1756-RIO module.
4.
Terminate both ends of a remote I/O network by using external resistors
attached to the physical ends of the network.
There should be two terminators at the ends network. The terminator is
connected between Line 1 (blue) and line 2 (clear).
