Re: 9Xtreme, FrSky DJT, no servo output

The signal should normally drive both high and low. The Assan should still work. I would put the resistor on the back board, otherwise you would need to put one in every DJT. Mike. To be complete. - The Assan module didn't work with the resistor on the back plate. So I soldered the resistor inside ...

Re: 9Xtreme, FrSky DJT, no servo output

Your a genius it seems to work.
Tomorrow I will solder it permanently in place.
Can I still use the Assan ?
I consider to solder the resistance internally in the DJT module.

Thanks,

Fred

1.
The numbers are,
cal 1.0 -0.8 -102.8 -2.8

2.
PPM Output
Self Test Failure.

Also, on the receiver, is the green LED on dimly (which it should be when working correctly) ?
When connecting battery to Rx from bright blinking RED Led to dim GREEN Led

This could be your problem.

The Red power wire was connected to the center Pin of channel 8
The Black to the ground.

Re: 9Xtreme, FrSky DJT, no servo output

However, you do see the A1 telemetry value. Do you also see RSSI and TSSI values ? Here pic's with the Rx battery not connected (lower pic) With Rx battery connected (upper pic) I am not really sure about the A1 It is internally coupled. I still have a lot to find out. A2 is not connected Yet, I or...

Re: 9Xtreme, FrSky DJT, no servo output

Did your radio have any mod done on the PPM circuit before you installed the 9xtreme board? Please post a good picture of your back board.. I did no mods on the backboard. (see pic.) What you are describing makes no sense as it points to two broken DJT modules, which is hard to believe. But it woul...

Re: 9Xtreme, FrSky DJT, no servo output

OK, while you get no servo response, are the servos holding their centre position, or are they just not being driven?
They seem not to be driven.

When I decenter them before connecting to the battery, they don't move at all.

Re: 9Xtreme, FrSky DJT, no servo output

Correct
For the RSSI and TSSI, I will comeback on that tomorrow.
(time here is 00.24 AM)

Yes, the servos are correctly connected.
Assan: signal upper pin
FrSky: Signal down pin

Re: 9Xtreme, FrSky DJT, no servo output

OK I did that. Still the same. the only problem is that the conical tap helped to align the pins, is not so easy now to put in the module. Now I took the PCB out of the case, put it in the bay, the pins are sticking out now like +_2mm. Still the same. I measured with a multimeter, al pins have conta...

Re: 9Xtreme, FrSky DJT, no servo output

Trimmed, cutting ....just semantics. :D

I CUTTED the opening on the backside of the DJT modules.
They "snap" in the module bay.
But this can not be the issue, module A, worked before, both with SmartieParts 9x Programmer and the 9Xtreme.

Re: 9Xtreme, FrSky DJT, no servo output

You said "Everything worked and I could switch to my Assan X8J Tx module", does this mean the DJT did work at that time? Yes I assume the DJT worked OK before you upgraded to the 9Xtreme Yes, and also after the upgrade to 9xtreme. I then started to bind different Rx's, and at some point I hat the s...

I don't know what to do anymore, maybe You can put me in the right direction. After successfully installing 9Xtreme, I run in some problem. (FW:V.3531-Mike ersky9x-r218) Everything worked and I could switch to my Assan X8J Tx module. So I started to play around with the different settings Then with ...
