Installation and Quick Setup
Enter the interface menu as described above. Then press the FUNCTION UP button to
display the “I/O:” function. Now press the VALUE UP button until “Parallel” is displayed
(or CX/TX if that option is installed). Now press the FUNCTION UP button again to display
the “Data Bits:” function. Use the VALUE UP button to select either 7 or 8 data bits as
required by your computer and/or software. This will normally be set to 8.
Finally, press the SETUP button to exit the setup mode and reset the printer. The printer is
now ready to receive parallel data.
RS-232C Serial Interface
A 25-pin female “D” type connector is located on the rear of the printer immediately to the
right of the 36-pin parallel connector (or above it if the coaxial/twinaxial interface is
installed). Connect a shielded cable between your computer and this connector. The pin-out
for this connector is shown below.

RS-232C Serial Interface Connector.
To configure the printer for serial data, more information is required than for some of the
other interfaces. In particular, you must know the baud rate, number of data bits, type of
parity checking, and flow control method required by your computer. Check your computer
manual or contact your computer dealer for this information.
Enter the interface menu as described above. Then press the FUNCTION UP button to
display the “I/O:” function. Now press the VALUE UP button until “Serial” is displayed.
Before proceeding, the factory default values for the RS-232C serial configuration are 9600
baud, 8-data bits, no parity, busy-polarity low, and XON/XOFF and ETX/ACK handshakes
off. 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.
