Can someone with a Minitor VI programming cradle tell me if one of the four pins is 5V from the USB cable? I'd guess the ground pin will be the same ground as the charger, but there are three more pins. Tx, Rx, and ??? If I can get help on that fourth pin, I can figure out the rest. I made a Minitor V programmer recently and was easily able to pull up the codeplug. I'd like to do the same for my Minitor VI and add another set of call tones for it.
