3.16 PANEL BACKLIGHTING – J1 PIN 25
Connect to aircraft panel dimming bus. The transceiver is capable of supporting 28 VAC/DC
or 5 VAC/DC backlighting circuits. Select 28 volts or 5 volts via the configuration menu
(see section 2.17). No damage will occur if the wrong setting is made.
3.17 POWER
JUMPER
The radio must be turned on manually each time the avionics bus is switched on. If it is
desired that the radio comes on with the radio master in the aircraft, remove the right side
panel from the radio and install the supplied 0.1” jumper across JP1 (two pins) near the rear
of the radio on the right side of the MCU board. The radio is shipped with the jumper on
only one of the two pins. If you attempt to turn off the radio with the jumper installed, it
will just come back on again in 5 seconds. Turning the avionics bus or battery master
switch off will now be required to de-energize the radio.
