Connection between the Host (PC) and the Terminal (ECR)

Note: If the connector of the Host PC is “9 PIN D-SUB,” the PIN num-ber is the same as that of the ECR.

5. SETTING OF RS232 PORT

The signal of 9-pin for RS232 port can be changed to “RI” or “+5V” bypositioning the short pin of “SP3” on the main PWB. However the factory-shipped location of the short pin varies dependingon the models.

Specifications of RS232 port

Usage: For Standard RS232 port

Connector: D-SUB 9pin

Data rate: max. 38,400 bps.
