Product Review (submitted on October 12, 2013):

With most RS-232 test jigs you see one color for positive, another for negative, and no light for no signal. The lights on this adapter are only on when the signal is "active" - you don't get any indication if the signal is driven from the other side. So it works, so I still need to carry an RS-232 tester with full lights when I want to diagnose a balky connection
