0 should be used. An additional card would use a value of 1.
NumRepeats: (optional)
This defines how many times the test is run. The default (if not entered) is 1 time. A value of 0 runs the test
infinitely. Pressing any key exits the loop.

960L Troubleshooting Tools:

As outlined in the sections on Functional Diagnostic Test Scripts and in the Functional Diagnostic
Descriptions custom test scripts can be implemented and individual tests can be performed to troubleshoot
defective 960Ls. In order to perform these actions a PS/2 keyboard must be connected to the LARC2 prior
to powering on the 960L. See these sections for information on how to use the keyboard to perform these
functions.
