Thanks for a poster confirming that 4 output wires are available.
Apologies for giving the impression that I may be attempting to rip-off BK products. I can see why you may have thought that and after posting I did sort of think that the information I want is far too proprietary.
I wanted this information for electronic circuit design purposes, but can't really say anything, otherwise that would be advertising on your forum. So, I won't talk about it anymore as even this is advertising probably.
I'll talk about other things instead
