(4) Communication

POINT

Refer to Chapter 15 for the communication function.

Signal	Signal	Connector	Functions/Applications
	symbol	pin No.
RS-422 I/F	SDP	CN3-9	RS-422 and RS-232C functions cannot be used together.
	SDN	CN3-19	Choose either one in parameter No. 16.
	RDP	CN3-5
	RDN	CN3-15
RS-422 termination	TRE	CN3-10	Termination resistor connection terminal of RS-422 interface.
