Connecting the Peripheral RS485 Communications Cable
Connect peripheral RS485 communications cables to JX01. All RS485 communications cables
are connected in the same way. This section describes how to connect two RS485
communications cables.

Do not connect a peripheral RS485 communications cable to the RS485-1 port (ports 1 and 2
⚫
on the JX01), because the PID module communications cable has connected to this port.
For the smart array controller that supports the access of two PLC routes, do not connect a
⚫
peripheral RS485 communications cable to the RS485-2 port (ports 3 and 4 on the JX01),
because the PLC CCO module communications cable has connected to this port.
1. Prepare a communications cable.
2. Connect the communications cable to the JX01 terminal block.
3. Crimp an OT terminal for the shield layer and connect the shield layer to the ground point in the
cabinet.
4. Bind the communications cable.
