Best way would be a scope if you had one. Is there any way you can connect the LED to the parallel port side of the BOB, that would let you see if the BOB is passing the signal correctly.

I was thinking a scope would be quite nice as well...
As far as testing the bob parallel output, I just unplugeed the cable from the pc, and turned on the control box to test with an led on the homeswitch pin (pin11) and the other end to ground. However, when I turn on the power, the motors start going crazy. So, I am guessing I need to test the pins
while its plugged into the computer which makes it kind of difficult to access the pins.
Is there another way to test this?
