Connecting the Printer to Your Host
1. You can connect the printer with any standard Centronics cable to the parallel port of the
host computer.
2. Or, 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.)
Note: Using Centronics allows for a much higher communication speed
than serial.

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 the same between printer
and host.
Caution: Pin 9 on the serial port is directly connected to +5volts DC. It
is suggested that this pin be not connected in your cable, unless
required.
To change the Baud Rate:
FM4402: Send the <STX>KI8n command to the printer. See the System
Setting Commands section for more details.
FM4602/4603: The switches on the back control Baud Rate. See the Back
Panel Switches section for more details
