I apologize if this runs a bit long. We have an APX7500 connected to our APCO25 trunk and we are trying to configure it to activate VIP1 on Accessory 2 (Pins 3 & 4) when a private call or call alert comes in. Instead of tell you all what I've done already, if I have a radio correctly configured to operate on the trunk, what steps do I need to take to activate the VIP1 so we can fire a relay off of that connector. It looks simple, but we can't seem to make it work. multimeter testing shows us having proper +13.2v coming from pin 4 when sent to ground, but we also see that coming from pin 3 to ground as well while not activated. Not sure if that is important to anyone, but we were grabbing at straws toward the end. I guess this didn't run as long as I thought it would.
