6. Corridor display and mainframe connection
7. Wireless transmitter and mainframe wiring
Wires for wireless transmitters are divided into two groups, one group is for power cord (+12V, COM), and the other
group is for data signal and power control cord (A, B, Ctr). Connect (+12V, COM) on the wireless transmitter
respectively to the positive and negative poles of the DC12V500mA; connect A, B, Ctr and COM on the wireless
transmitter respectively to A, B, Ctr and COM on the mainframe.
