Pin - Signal Name
A - AUX AUDIO IN
This input will take audio from an external source unit and add to the normal
transceiver audio. Not used in normal installations.
B - AUX SIDETONE
This input will take alert tone audio from an external source and produce
headset sidetone. Not used in normal installations.
C - RESERVED SPARE A
D - CONTROL GROUND
This ground goes to the control head. Loss of this ground may disable the RT-
5000 or cause intermittent function.
E - RS-422 ANTENNA TRANSMIT HI
This output is the active high sense serial data output and meets EIA RS-485
voltage levels. The data from this output controls the RT-5000 antenna.
F - RS-422 ANTENNA TRANSMIT LO
This output is the active low sense serial data output and meets EIA RS-485
voltage levels. The data from this output controls the RT-5000 antenna.
G - RS-422 ANTENNA RECEIVE LO
This input is the active low sense serial data output and meets EIA RS-485
voltage levels. The data from this input comes from the RT-5000 antenna.
H - RS-422 ANTENNA RECEIVE HI
This input is the active high sense serial data output and meets EIA RS-485
voltage levels. The data from this input comes from the RT-5000 antenna.
J - RS-422 CONTROL TRANSMIT HI
This output is the active high sense serial data output, meets EIA RS-485 voltage
levels.
K - RS-422 CONTROL TRANSMIT LO
This output is the active low sense serial data output, meets EIA RS-485 voltage
levels.
L - RS-422 CONTROL RECEIVE LO
This input is the active low sense serial data input and meets EIA RS-485 voltage
levels. The data from this input comes from the C-5000.
M - RS-422 CONTROL RECEIVE HI
This input is the active high sense serial data input and meets EIA RS-485
voltage levels. The data from this input comes from the C-5000.
