A ground on this pin invokes nighttime lighting mode to reduce
the brightness of the panel lighting. Lighting levels are
configurable
Grounding this pin enables the power supply in remote radios
being controlled by the RT-7000 RCDU
These pins provide an RS-485 data signal to secondary RCDU
(see Figure 7-5)
These pins provide an RS-485 data signal to the primary
RCDU (see Figure 7-5)
Remote Radio Control
1 TX+/-
These pins provide an RS-422 data signal to the RT-7000 PMR
A ground on this pin invokes NVIS lighting mode to reduce the
brightness of the panel lighting
Remote Radio Control
RX+/-
These pins receive an RS-422 data signal from the RT-7000

5 VDC/28 VDC
Backlighting, Ground
These pins provide the backlighting reference to the panel.
Selection of 5 VDC or 28 VDC is a programmable option The
RT-7000 PMR does not draw significant power from the
backlighting source, but only uses it as a reference.
