RS232 SERIAL INTERFACE
Female DB9 connector
J5
1 DTR
2 TX During transmission, takes the values “0” and “1” depending on data.
3 RX During reception, takes the values “0” and “1” depending on data.
4 n.c.
5 GND
6 DTR When “1”, printer is power on.
7 CTS
8 RTS When “1”, printer is ready to receive data
9 n.c.
Note: Given the presence of the RS232 standard, logic value “0” corresponds to a voltage level of between +3Vdc
and +15Vdc and logic value “1” corresponds to a voltage level of between -3Vdc and -15Vdc.
Note: KPM216HII ETH > PC connection
