Hi Skip025, Yeah, potting material makes it difficult to find out what's inside, but you could just buzz out the connector for the wire jumpers between these pins if you cared to. I, too, have made many adapters to use with my KPG4 clone. Even did a King mobile with it. Now I'm trying to find the pinout on the EF Johnson Challenger to make an adapter for that. Got the schematic but the pins aren't clear as it is a double sided PC board connection.
I added an LED and a 9 volt connector to mine. The LED lets me know it's getting power and the battery supplies power when programming portables that don't have the power pin or mobiles that may have the internal resistor (fuse) blown on the +12 line. I have not wanted to try drawing power off the computer. There are just too many variables there depending on how much current individual computers can supply through the RS232 port pins. Guess, I have not noticed any RF interference from the MAX232 chip version but then I don't have any AM radios in the shop. Cheers and Merry Christmas, Art - KC7GF, Golden, CO where it's already a white Christmas. Yahoo!
