3.3.3 Connector P-3 Pinout Descriptions
P3-1 &
P3-9:
Display Primary Power Input
(22-33Vdc). Connection to both pins is required using two 20AWG wires and
a 5 ampere circuit breaker. Maximum power required is 35 watts. Connection
to the avionics bus is recommended to reduce voltage fluctuations during
engine start.
P3-3 &
P3-11: Display Power Return Input
Pins 3 and 11 are the aircraft ground input connections. Connection to both
pins is required using two 20 AWG wires. Either pin should also be used for
the digital signal ground (shields) return, as required. The number of shields
will vary depending upon the functions wired to Connector P3.
P3-2:
GPS OBS- or HOLD- Command Discrete Output or TACAN Relay Out
Open Drain active-low output used to operate the OBS function of Bendix/King
KLN-90 GPS receivers or the HOLD function of the II Morrow and Garmin
GPS receivers. Accessible during normal use from the pilots GPS MODE soft
key.
