Sandel Avionics Tech Note on Garmin GTN-6xx/7xx Interfaced with Sandel ST3400.

G’Day, Charlie here:

First, in case you are not aware, we have a NEW ST3400 installation manual in our online resource center. Download it here.

Recently we added the Garmin GTN-6xx/7xx interface for the ST3400. The interface includes ARINC 429 and RS-232 for the GPS Position, Flight Plan, GPS Altitude, and NAV/ILS information. Please refer to sheet 23 in the Sandel ST3400 PN: 82002 IM-K Installation Manual. Sheet 23 shows the interface as a Class B operation. For a Class A operation, Pressure Altitude needs to be added to the ST3400 for sudden loss of altitude.

Sandel Tech Note on GTN Software

From Sandel Product Support: Charlie here, I have found a problem with the current software level 5.0 on the Garmin GTN 750/650 series units when interfaced to Sandel displays. The problem is when you have to configure any GAMA output port.
