Transponder for MGL XTreme
We have just completed final testing of the remote transponder interface for the MGL XTreme EFIS and will be releasing as first installment the interface to the new Sandia Aerospace STX165R remote transponder box with the Garrecht transponder following soon.

This makes the XTreme a viable and easy to use control head for a transponder, saving panel space and overall system cost as the Sandia is very well priced. An additional advantage is that the transponder itself can now be mounted in a convenient location.

Do you have any plans to support remote mode S (ADSB-out) transponders? I think the STX165(R) units are only mode-C. We're putting a V6 and an Extreme into a Onex here at KDVO but want to future-proof for ADSB it so we're using a Trig TT22 and will wait for that magic TSO'd GPS in puck. Any plans to interface to Trig's remote units?

See our website.
In particular we support the Garrecht/MGL transponder VT0102 in both class 1 and class 2. This is connected via a single CAN interface to the EFIS and only needs power and antenna.
Extended squitter (ADSB-OUT) is also supported via the same interface (nothing more to do, no additional GPS or NMEA feed required).

You control the transponder using the "radio stack" component. There is a separate configuration menu for the transponder (here you enter aircraft particulars such as the ICAO code, tail number etc).

On the IEFIS you control the transponder using the touch screen (just tap on the transponder status display and a "big" transponder pops up).

Regardless of transponder type (mode-c or mode-s), if you have a separate ADSB transceiver you can also elect to have them synchronized automatically - in other words if you enter a squawk code on the transponder or ADSB the other follows automatically.

In case of our iEFIS system which supports multiple, simultaneous GPS sources you can configure to have ADSB-OUT source data from a certified GPS connected to the iBOX NMEA port or alternatively from a Garmin 430 or compatible via ARINC.

The built in GPS of the iBOX supports WAAS and RAIM with satellite fault exclusion down to precision approach limits with appropriate warnings if limits are reached.
