Serial Interface Cable RS-232C | Lexmark 249X, 248X specs

Serial Interface Cable (RS-232C)

The recommended RS-232C serial cable is 50 feet long. This cable works with the IBM PS/2 series and other compatible host systems using a 25-pin male connector. The maximum total capacitance of the cable and the connector should be less than 2500 pF, or it will delay the signal transition by more than 4%.

Following is a diagram of the serial cable (Lexmark part number 1038693 (15.24 m or 50 ft.)).
