GRT EFIS with SafeFly 2020 GPS App Note
The GRT EFIS exchanges Setup, Control and GPS data with the echoUAT. The
echoUAT can also send ADS-B traffic and uplink data to GRT EFIS.

GRT EFIS Settings:
General Setup:
Serial Port X* In: Safe-Fly GPS and SPC
Serial Port X* Out: Safe-Fly GPS and SPC
Serial Port X* Rate: 115,200
SAVE
*Serial port “X” refers to the serial port on the EFIS that is wired to the “Serial Control In/Out”
of the Safe-Fly GPS module.
SPC Serial Port 1 Rate: 38400
SPC Serial Port 1 Output EchoUAT/TMAP
SPC Serial Port 1 Input EchoUAT/TMAP
Serial Port Y* In ADS-B
Serial Port Y* Rate 38,400 if connected to SafeFlySPC or 115,200 if connected to EFIS
SAVE
Serial port “Y” refers to the serial port used to receive ADS-B data into the EFIS. For best
performance the ADS-B In (Pin 5) on the EchoUAT should be wired directly to a high speed port
on the EFIS and not connected to the serial combiner on the SafeFly GPS. If wiring through the
SafeFly we recommend a baud rate of 38,400. If wiring directly to the GRT EFIS we recommend
115,200.
