Diagnostic screens
The following screens are used for diagnostic purposes only and usually do not require any
input from the installer.
GPS week number rollovers
The GPS week number rollovers screen tracks the number of GPS rollovers, which occur every
1024 weeks (19.7 years). The screen should display the following values, depending on the
year:
Dates
Rollover number
August 22, 1999 – April 6, 2019
1
April 7, 2019 – November 20, 2038
2
If the value shown on the screen is incorrect, edit the configuration and select the correct
rollover number.
Altitude input diagnostic
The altitude input diagnostic screen shows the current gray code altitude input from the parallel
altitude encoder and also displays the current altitude. You can use this screen to verify that a
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.
