GRT Avionics

I have the below configuration, noting that the associated documentation (esp. the TT22 doc) is not exactly in line with the below presumption:

- TT22 is connected to EFIS1 (there are two) via the 2020, using 2020 Serial 1 on Pin 20
- 2020 Serial 1 is configured for Safe-Fly NN31 at 9600 baud
- TT22 is configured for GRT Safe-Fly NN31, GPS/TIS rate of 9600 baud, and certification level of C

Is the above correct?

I do not have this system, so check with GRT.
But, I think, it is designed to run NN33 at 38.4 K baud rate.

The tested configuration is NN33 at 38400 baud. If your TT22 has older software (2.4 or older) you can get by with 19200. You also need to set the NACv to < 10. These settings are in the Safe-Fly GPS manual.
