/me looks at post dumbfounded

OK, how's this ?

As to batteries as test voltages for IC's :

Batteries are not a good way to test the inputs : As explained above, a voltage between ground (the "negative rail") and the positive rail will not give reliable info.

Digital inputs are just that: on or off; connect them to ground or (through a resistor) to positive rail voltage, don't test them with a "bias" voltage somewhere in between.



As to powering OI's through the comp port :

I've done it - I verified it on my team's equipment. It works on other team's equipment. I connected the 9V power supply to the Comp Port. I do not recommend that you do this; be very careful if you aren't sure.



As to channel selection using the four pole DIP switch on the OI :

The then-current manual only had a chart re: channel selector postions, with ON Off and X, and when we tried to use my system for the first time, no one could get the correct positions, or their assigned channels, and we abandoned the system for the rest of the match, although we used my Comp Port connector as a dongle !?!?!.

The current manual says ON is down, up is OFF. BTW, what does the light switch on your wall do ? The switch is clearly marked in tiny raised red-on-red letters which, when eventually seen and deciphered, say OPEN.
