Works fine integrating a uAvionix Ping ADS-B IN receiver or similar (eg SkyEcho) into the iEFIS.

They should be 120 ohms, not Kohms.

Pull-up resistor switched ON?
Should be OFF.

Re your fuel pressure- make sure you have the fuel pressure pull-up and pull-down switches set correctly for your fuel sensor.
Older automotive 'can' style resistive sensors- PU ON, PD OFF.
Newer 912 4-20mA style sensors- PU OFF, PD ON.
UMA style 0-5V active sensors- PU OFF, PD OFF.

it is not very clear to me where are stored the screens that you are working on, when you close the desing file a different screen is shown on the page that you are editing. Re files, simplest is to either use the SIM file manager to transfer files to the SD card, or us the script library generator...

The designed/simuator RDAC fuel level sliders don't work, but the fuel level system works fine on real hardware.
Just go for it, set up the level calibration in real life- it all works!

Simplest is to set the VOX at its upper limit- that way it will never open the intercom channel and your headset will remain quiet except when transmitting or receiving. When you press PTT the mic is always live, so the VOX setting does not affect transmission. Set your squelch and volume as require...

Select RDAC as the source for that channel- that way it will pick up the RDAC FL input.
The bits in the manual re analog channel setups mainly relate to using the direct analog inputs on the EMS2.

Best to use FL1- that is its intended use.
Routing, signal conditioning, tank linearisation and display are all available to you by default using that input.

So my understanding is that the MGL Extreme EMS will accept a signal from the fuel level sender either as ohms or as voltage depending on the RADAC switch setting. I'm debating using one of the cheaper float types versus the capacitance type MGL has on their website (which costs 10 times more) if I...
