4. SIGNAL CONNECTION DIAGRAM
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” by
positioning the short pin of “SP3” on the main PWB. 
However the factory-shipped location of the short pin varies depending
on the models.
Specifications of RS232 port
Usage: For Standard RS232 port
Connector: D-SUB 9pin
Data rate: max. 38,400 bps.
Power Supply: 5V/400mA (*)
