3.5.4.13.2 ADS-B Transmit Settings

This section describes configuration settings mainly for transmitting ADS-B messages. Some of
these settings are relevant for receiver only units as well.
3.5.4.13.2.1

"set addr" Command

This command is used to set the ICAO address of the aircraft. For example, to set the ICAO
address to ABCD12, enter "set addr ABCD12." The ICAO address must be entered as a hex
value. The FDL-978 Series requires the ICAO to be set to the aircraft's registered ICAO
address. This should be set for receivers and transceivers.
3.5.4.13.2.2

"set call sign" Command

This command sets the default call sign of the aircraft and is typically the aircraft tail number.
For example, to set the call sign to ABCD1234, enter "set call sign ABCD1234." The default call
sign is transmitted by a Transceiver if a call sign setting is not received from a configured
transmit controller (transponder, TC978, etc.). In a receiver the default call sign is for
informational purposes only.
3.5.4.13.2.3

"set gps" Command

This command sets the system design assurance level for the GPS input. Internal GPS should
be set to Level C. For external GPS units refer to the GPS manufacturer's data for setting
system design assurance level. This should be set for both receivers and transceivers.
