Analog inputs diagnostic
The analog inputs diagnostic screen shows the current reading of the lighting bus and ambient
light sensor to the nearest percentage, and the current reading of the internal temperature
sensor to the nearest degree Celsius.
GPS receive diagnostic
The GPS receive diagnostic screen shows the current reading of the GPS latitude, GPS
longitude, and Navigation Integrity Category (NIC).
GPS CN0 diagnostic
The GPS CN0 diagnostic screen shows the current value of GPS CN0 for all 12 channels.
Software versions diagnostic
The software versions diagnostic screen shows the DSC part number, version number, and
flash checksum.
Complex hardware versions diagnostic
The complex hardware versions diagnostic screen shows the FPGA part number, version
number, and flash checksum.
BIT diagnostic
The BIT diagnostic screen displays any Built In Test failure codes. If the screen displays all
zeros, no BIT failure has been detected. Otherwise, a “1” will display. Each number corresponds
with a specific failure, depending on its position in the string of numbers on the screen—failure
position 1 being the leftmost space, and failure position 19 being the rightmost space.
Reference the table below to determine which BIT has failed. Once all BIT failures have been
resolved, press
ENT
to clear all codes.
