3 SETTINGS
3.1 Overview
The TRT800 has the contingency of storing the following information
(For model differences refer to 1.3 Survey of Variants.):
• error logging
• one entry/eight entries for
o ICAO 24-Bit Aircraft Address (AA)
o Aircraft Category identification code (AC)
o Flight Identification (FID)
o ground switch availability
o interface configuration
AA, AC and FID are stored in a memory device inside the housing of the
D-SUB connector (included in delivery).
The cable with this connector shall remain in the aircraft even if the unit
is removed, to ensure that the ICAO aircraft address is fixed to the
aircraft.
3.1.1 Error Logging
Errors are counted and ordered in the sequence of their occurrence.
The error list can be displayed as described in chapter 3.2 Configuration
3.1.2 ICAO 24-Bit Aircraft Address (AA)
Ask your national aviation authority (e. g. in Germany: LBA, department
“Verkehrszulassung”) how to obtain the AA.
The assigned AA must not be modified at any time, because a duplicate
address would jeopardize the data surveillance and integrity figures of
Mode S.
If no AA is stored, after power on the display shows
“CRADLE OFF” and the transponder operates in Mode A/C.
