RS-422 Serial Interface Connector

To configure your printer for serial data, more information is required than for some other interfaces. In particular, you must know the baud rate, the number of data bits, the type of parity checking, and the handshaking or flow control method required by your computer. Check your computer manual or contact your computer dealer for this information.

Turn the printer on and enter the interface menu as described in the “Installation and Quick Setup” section. Press the FUNCTION UP button to display “I/O: n”. Then press the VALUE UP button until “n” is “Serial”.

The factory default values for the RS-422 serial configuration are 9600 baud, 8 data bits, no parity, XON/XOFF handshake enabled, and ETX/ACK handshake disabled. If your computer requires you to change any of these parameters, please refer to “Entering the Interface Setup Menu” in the “Operation” section of this manual. Otherwise, simply press SETUP again to exit the setup mode and reset the printer. The serial interface with the above parameters is now active.
