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.
Procedure
Step 1
Prepare communications cables.

Stripped length
Step 2
Connect the communications cables to the JX01 terminal block.
Step 3
Crimp an OT terminal on the shield layer, and then connect the shield layer to the cabinet
ground point.
Step 4
Bind the communications cables.
