Activating reverse thrust with Airbus TCA

Bought one of the above to add some realism to flying my Fenix A320-200. Since the hardware is for the Airbus simulation and has latches and markings relating to the use of reverse thrust, I assume Thrustmaster intended it should be possible to use their throttle levers per the real aircraft. Indeed, Jonathan Becket has a YouTube video showing how to set up this function for the FBW A320, using the aircraft tablet. Trouble is my FBW tablet shows a white dot against ‘Reverser on Axis’ rather than a blue one, and accordingly there is no facility offered on the indents page for anything position lower than forward idle. Since the throttle latches don’t activate any buttons, virtual or otherwise, I assume there has to be some other way of the Sim knowing where the throttles are, and thus that reverse thrust should be applied. But what? Is there a way of setting the axis zero at the lower end of the full travel of the throttle levers, ie below the latch point? At present, my zero is just above the latch point, and it remains at that when the latches are released and the levers moved on to the bottom end of their travel. I’d appreciate advice from someone who has the reverse thrust working as intended ( ie not the workaround of a separate reverse switch followed by pushing the throttles forward again), and can tell me the secret.

PS I know I am not the first to raise this, and I will trawl again through the other similar threads on this forum, but so far I haven’t spotted the answer to my difficulty.

Have you calibrated your throttles?

Thanks for the reply. I had already found your Fenix calibrating post a few days ago and followed it. But it did not sort the problem I described. And I see you did not include any movement of the levers to the reverse thrust positions in your instructions.

Does your TCA work in the real life fashion? That is to say, when you bring the thrust levers back to the latch stop, the engines are at idle, and when you lift the latches, and you pull the levers back for the rest of their travel, they actuate reverse idle followed by max reverse thrust? If so, can you tell me how you achieved that?

In my Thrustmaster game controller box (reached through Windows search/joy.cpl) my TCA shows the green bar reducing to nothing when the levers reach the latch guarded position (ie forward idle), and remaining blank when the latches are lifted and the levers brought back further.

It’s woking as it should.also in reverse.
The tric is that you had to follow my description as from step 1 until step 12. Mark that the last mechanical position is IDLE (on not idle reverse!) AND check the settings of the trhottle axis in the sim NOT being 0-100%.
After this hardware setting (=windows) you proceed with the calibration with the mcdu. Atthe end of the day you can check th evalues in the file calibration.xml located in “C:\ProgramData\Fenix\FenixSim A320\calibration.xml”.
