Ports
There are 3 different types of ports of interest to us on the main control board
There are 3 ports, pin5 selects which is active on the shared RS485 bus at any given time
These are only 6 pin and can only be used for dedicated feature buttons. One of the pins is 9.7V but function of others unknown as no activity while idle and I have no buttons to test with

This port connects to the ADCM Hub, which then allows for collecting an additional main top panel or the wireless adapter to use with the hand-held controller or software via adapter for a PC
- Pin 1 is 15V
- Pins 3,5,8 & 9 all carry constant 5V while idle
