Power
The control head is supplied with 13.8V from an AC to DC plug pack.
The remote power switch line J5-3 (controlled by the Primary control head)
controls the 5V regulators on the Secondary heads and interface board.
Data
A separate RS-485 transmitter and receiver in each control head provide the
data communications between the radio and control heads.
Connections
Connection to the remote control heads is via the micromatch to RJ45 cable
at J5, which connects to the RJ45 Wallbox. The wallbox connects to the
multi-drop cable, which connects to the RJ45 Wallbox for each control
head and the radio.
DC Input and speaker output is via a 4 way phoenix connector at J6. The
supplied cable 219-02907-00 connects to J6. The plug pack (supplied
separately) connects to this cable assembly.
The DC input is polarity protected so that in the event of reverse polarity
being applied the head will not function, no damage will occur.
