E N-R4-IM

• States of RS-422A/485 changeover switch and terminating

resistance switch

* The factory setting is RS-485 communication mode and terminating

resistance OFF.

■ When connecting RS-422A or RS-485 (1:1 connection)

■ RS-485 connection (multi-drop connection)

* At the end of the RS-485 trunk line, set the terminator to ON.

■ Connecting the code reader

Connect the code reader to the head port of the N-R4.

Pin layout of the head port

■ Connecting the power supply

Connect the 24 VDC power supply to the power terminal of the N-R4.

The dimensions of crimp contacts used for wiring should be as follows:
