Parallel Port (on Video Adapter) Check

Use this option to test the operation of an additional parallel port on a video adapter. To perform the test, you must insert the special loop-back connector into the parallel port on the video adapter so that the computer can check individual pins of the port.

This test is similar to the Parallel Port Check. For more details, see the description of the Parallel Port (Printer Interface) Check.

Serial Port (RS-232C Port) Check

Use this option to test the functions of the primary serial communications (RS-232C) port. To perform the test, you must insert a special loop-back connector into the RS-232C port so that the computer can check individual pins of the port. Contact your dealer if you need a loop-back connector. Note that a different connector is required to test the parallel port.

When you select option 11 from the Device List, you see these prompts:

Attach loop-back connector to serial port before starting the check.
