It seems you are trying to install firmware to a device - not updating the EFIS. To update the EFIS you merely copy the file (EXP2.BIN) for a G2 iEFIS to the root folder of the SD card, insert and switch on. If the EFIS is happy with your file the update happens automatically and you will see messag...

Your RDAC should show a double flash every second - if it is a single flash it confirms what your EFIS is telling you - there is no data communication between the two. How did you wire your resistors and CAN bus and what are the resistor values ?

From your description I must assume that your audio wiring to your headset (sockets) is highly suspect - did you insulate your headset and microphone sockets from your panel or mounting location (if metal) ? Did you use shielded wiring as shown in the diagrams and are the shields NOT used as signal ...

The T16 provides an input for a squat switch (switch to ground - closed when on the ground). You can also do this via iBOX or iEFIS Extender (and then choose the selected input as squat switch) but I would assume in the T16 case you would simply wire the switch into the T16. Note: Transponder checks...

Is your LED on the RDAC flashing ?

Sadly I do not have the circuit diagram of the V6 - while it was based on a early prototype radio I designed around 2004 but never put into production it has changed a bit. The design was taken over by another company that then created the V10 and later the V6 and we sold it as a MGL radio for a whi...

It's a fully featured transponder - at minimum and if used with our EFIS systems you need the CAN bus and power/ground. That's it. It will in this case use the EFIS GPS for the ADS-B out (or the SP-12 GPS if one is connected). In other words - it's the same as if you were to use the Trig with our li...

Well, in the meantime I have managed to get some certainty around the certification issue. Transponders designed to TSO-C112F do not need to be formally certified is installed in experimentals or similar or can be fitted via the STC route in other aircraft. It's actually the same as for the VHF tran...

Just a bit of further information on this issue. The SP-12 contains NexNav Micro-I GPS module which is a FAA approved device (it is used in practically all of the approved or certified GPS receivers compliant to TSO-C199 class B). This device transmits GPS altitude relative to the ellipsoid which is...

There has not been an update to the A16 since release - same hardware. Yes 123Mhz is a bit too high for the switch mode power supplies - not impossible but we on purpose use quite ancient switch mode chips - the L5973 which is a low frequency chip and quite bullet proof. I can't tie 123Mhz to anythi...
