Altitude input diagnostic
The altitude input diagnostic screen shows the current gray code altitude input from the parallel

parallel altitude encoder is properly connected. If a serial altitude encoder is connected, or there
is no altitude encoder connected,
the altitude input will display all 0’s.
External inputs diagnostic
The external digital inputs diagnostic screen shows if the IDENT and standby modes are active
or inactive. It also shows if the squat switch is indicating that the aircraft is ground, airborne, or
unknown. You can use this screen to verify that the squat switch settings are properly
configured.
