(3) RT-5000 Connector J101
(a) Aux Audio In (Pin A)
This input will take audio from an external source unit and add to the normal
transceiver audio.
(b) Aux Sidetone (Pin B)
This input will take alert tone audio from an external source and produce headset
sidetone.
(c) Key (Pin C)
This input is used to input MTM information.
(d) Control Gnd (Pin D)
This ground goes to the control head. Loss of this ground may disable the RT-5000
or cause intermittent function.
(e) Ant RX H (Pin E)
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) Ant RX L (Pin F)
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) ANT TX L (Pin G)
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) ANT TX H (Pin H)
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.
(i) CONTROL RX H (Pin J)
This output is the active high sense serial data output, meets EIA RS-485 voltage
levels, and is tri-stated when the TAKE CONTROL line is grounded.
(j) CONTROL RX L (Pin K)
This output is the active low sense serial data output, meets EIA RS-485 voltage
levels, and is tri-stated when the TAKE CONTROL line is grounded.
