I have a KRC2 using the AUX bus which works OK , switching the RATPAK 5 6 remote box and showing the LED indicators of the RATPAK switch box.
I would like to be able to turn off the KRC2 to allow manual switching of the antennas - I am feeding 12vdc to the SOURCE driver terminal strip J5 in the KRC2 and if I turn off that supply , there is a diode D4 that feeds 12 vdc from the normal DC input jack on the KRC2 to the SOURCE driver Vbb so even if I turn the other 12v supply off , it stays latched on the last band . If I remove the 12 vdc feeding the microprocessor , but leave the AUX BUSS on ACC connected , the K3 freezes and will not reboot .If I remove the conection between the KRC2 and the ACC connector , then it will reboot and is normal. Is this normal AUX bus behaviour ? If so looks like I will either clip D4 - or ressurect my relay switch box to completely isolate the 7 wires from either KRC2 or the RATPAK manual switch to the remote switch box.
