NAV Super Flag Output: | Output capable of driving positive logic NAV Super |
(Pin 10) | Flag by sourcing up to 500mA for flag out of view (NAV |
| valid). |
RS422 input: | Input capable of receiving serial OBS data from |
(Pins 11 & 27) | Collins Pro Line 2 EFIS DSP unit. |
GPS approach arm low: | Input, when grounded, controls approach mode. |
(Pin 9) |
|
GPS OBS: | Capable of interfacing with a standard OBS resolver. |
(Pins 4,14,35 and 37) |
|
ARINC 429 Input A & B: | Input capable of receiving data from ARINC 429 (low |
(Pins 32 & 33) | speed) devices as listed in Section 4. |
Battery
1.2.3.2 26 PIN CONNECTOR (J102)
MIC Audio Hi and Lo:: | Input requiring 275mV RMS into 470 ohm load. |
(Pins 2 and 3) | (Standard carbon or dynamic MIC containing |
| transistorized |
MIC Key: | Input, when grounded, keys the transmitter. |
(Pin4) |
|
COMM Audio Hi and Lo: | Output capable of driving a 500 ohm load with |
(Pins 5 and 6) | 100mW. |
MIC Intercomm: | Input requiring 125mV RMS into 470 ohm load. |
(Pin 8) | (Standard carbon or dynamic MIC containing |
| transistorized |
Remote Transfer: | Input, when grounded, swaps the active and |
(Pin 10) | standby COMM frequencies. |
TX Interlock: | Input, when grounded, reduces receiver sensitivity |
(Pin 12) | so squelch will not break when another transceiver is |
| keyed. |
Altimeter input: | Capable of receiving encoded output data from any |
(Pins | parallel altimeter device. |
Remote Enter: | Input, when ground, functions the same as the enter |
(Pin 26) | key on the GNC 300 front panel. |
