5.3 RJ45 Wallbox
Wall boxes are connected in a multi drop arrangement (i.e. all wiresare
connected in parallel), with one wallbox for each control head and one
wallbox for the radio. View below of the RJ45 Wallbox terminals is from
the top.
The following pins should be paired:
■ Power Switch line and Ground
■ Audio
■ Data 1A & 1B
■ Data 2A & 2B
Note Polarity of the data pairs is important. Earthing of the cable screen
should only occur at the radio interface wallbox.
Note Some Cat 5 cable installations (normally used for network or
PABX connection) have pin reversal on some or all pins. Check
connection polarities if control heads do not function as expected.
