That is absolutely correct.  The Dave Rat/Sound Tools XLR sniffer can't detect that either when used with ordinary phantom power.  However, it can if you use the battery powered sender unit with it as it puts two different voltages on pins 2 and 3.  I could also do that with mine but decided not to as in reality, as you point out, cables don't re-wire themselves, they just short out or go open circuit. The swapped connections it does indicate are just extras which might be useful sometimes.

I have a couple of the RAT sender/receivers.
At the show, I don't really care what's wrong, just that the cable is "bad"
If I don't see 3 green, a knot get's tied at the end of the cable, and it is put aside for some shop time.
I always wondered what was in the RAT tool.
Thanks for sharing.
Simple, but brilliant all at the same time.

Just to be clear, this isn't a copy of the Sound Tools device (I wouldn't do that).  Mine is different.  You can find the Sound Tools circuit by doing a patent search.

I actually think mine is more logical.  The error codes can be remembered quite easily.

Hi Steve.
Sorry, I didn't mean to imply anything.
YOUR design is simple, and brilliant.
I can't imagine the business end of the RAT tester is a lot different.

No problem. I wasn’t presuming that you might have thought that. I just thought I should generally point out that it wasn’t a copy.
