Interfaces

When using the serial interface, your printer has the following differences from the serial interface on some other printers:

•

•

The printer returns XON/XOFF with 2 stop bits in all cases.

The printer does not support DTR inversion.

Using the RS-232C Serial Interface

This section describes how to use the RS-232C serial interface. If you are using RS-422, see “Using the RS-422 Serial Interface” on page 8-36.

How to Connect the RS-232C Serial Interface

Use Lexmark serial cable P/N 1038693 (15.24 m or 50 ft) to connect the serial interface.

RS-232C Serial Cable Pin Assignments

The RS-232C serial cable appears as follows:

		25-Pin	25-Pin
13	25	D-Shell	D-Shell	13	25
		(Male)	(Female)

1	14	1	14
	Printer	Computer
	Side	Side
