RS-485 communication equipment
One-pair wiring and two-pair wiring (for RS-422) are applicable for RS-485 communication. Wire according to the counterpart
equipment.
The wiring that can be used is limited by the control line setting in the communication settings (Page 136 Communication
Settings).

Class-D grounding
*1 Make sure to perform Class-D grounding on the shield of the twisted pair cable to be connected.
*2 Make sure to provide a termination resistor at both ends of the wire. The built-in RS-485 port, FX5-485-BD and FX5-485ADP have built-
in termination resistors. Set the termination resistor selector switch to 110 .
Precautions
When the control line is set to [Bidirectional Full Duplex], the built-in RS-485 port, FX-485-BD and FX5-485ADP become a
full-duplex interface, and echo will occur.
