Interface
- No connection to serial port
Altitude Altitude, Airspeed, and Vertical Rate data input. Format for
Input air data sensors using the protocol in Section 4.2.
Altitude Altitude data. Format for air data sensors using the
Input protocol in Section 4.1.
GPS Input GPS position, velocity, time, and integrity data input and
output. Selects use of the internal GPS (models with GPS
only). Baud rate must be set to 19200. Internal GPS is
only valid for serial port 1. The internal GPS data is used
by the FDL-DB Dual Band Series and GPS data is
automatically output at 19200 baud on serial output
port 1 using the FFS/Chelton Protocol. The output is
TSO-C145c Class Beta 1 certified and can be used as
an ADS-B position source or navigation source.
GPS Input GPS position, velocity, time, and integrity data input.
Format for the FFS 1201 or other sensors that support the
FFS/Chelton Protocol. Typically configured on port 1.
GPS Input GPS position, velocity, time, and integrity data input.
Format for the Garmin Series 400/500 ADS-B Plus GPS
Protocol.
Control Squawk Code, IDENT, Call Sign, mode (standby/alt
(2)
Input inhibit), and altitude data input. Format for the GSL-71
controller or SL70/R transponder.
Control Squawk Code, IDENT, and mode (standby/alt inhibit)
(2)
Input control input format from GTX 330/33/327/32
transponders.
Control Squawk Code, IDENT, Call Sign, and mode (standby/alt
(3)
Input inhibit). Enables display control from an MX-20, GMX-200,
or other displays using the GDL/FDL protocol. The
corresponding serial output port must be configured to
TIS-FIS or MX-20 at the same baud rate to enable display
control input.
