Connecting the Printer to Your Host
1. You can connect the printer with any standard Centronics Parallel cable to the parallel port of
the host computer.
2. Alternatively you can connect the printer with a serial cable to the RS-232C port of your
computer or terminal. (For PC compatibles, the RS-232C port is COM1, COM2 or COM3.)

3. If you use the serial port with your own cable, refer to the Appendix A and check the pin
connection. Be sure that the speed (baud rate) and protocol are consistent between printer
and host.
Caution: Pin 9 on the serial port is directly connected to +5volts DC. It is
suggested that this pin is not connected in your cable, unless required.
The factory default parameters of serial port are:
Speed (baud rate) 9600
Data format 1 start bit,
8 data bits and
1 stop bit.
Parity None
Handshaking
(Flow control) XON/XOFF as well as
RTS/CTS
Note: It is not necessary to set a switch or send a command for the parallel
and serial port selection. The printer automatically detects the active
port.
