Well I've fixed the problem, more or less. I did some bench testing and discovered that the JR module would accept a PPM signal from the PCTx with no problem. My challenge then was to force the transmitter to send the PPM from the trainer port to the module, while overriding the PPM from the transmi...

Yes I'm using the original firmware. I don't have the USB adapter to flash new firmware. I tried 2 4K7s in a series in place of the 150K still nothing. I took apart the entire circuit and rebuilt it, and found that I had wired the circuit incorrectly the first time, I had transposed the pins on the ...

Well i tried both PPSIM ON and OFF just to be sure. Neither worked. Here's my SETUP pages: SETUP 2/11 Name Airplane Timer 10:00 Trigger OFF TriggerB --- Timer Count Up T-Trim ON T-Expo ON Trim Inc Medium Trim Sw --- Beep Cnt RETA123 Proto PPM 8CH 300uSec PPM FrLen 21.5mSec Shift Sel POS E.

According to that diagram I'm trying to get "Existing Master".

Take PPM from the Jack Socket, and sent it to the TX Module, that's what I want to do.

MikeB wrote: the 9X will actually be using the trainer input to send a PPM signal out.

Just to clarify: are you saying the 9XR will take the PPM signal from the trainer port and sent it to the module bay pin?

I think that's what you're saying, but I just want to be sure.

I reviewed another hack from the PCTx site found HERE and they had the PPM from the PCTx on the Base leg of the transistor, while the PPM signal going to the buddy port was on the Collector leg. I tried their circuit (and it didn't work either) and then I tried the Gruvin hack with the PPM from the ...

So I went ahead and plugged the JR trainer cord with the boosted signal into the 9XR's trainer port and got nothing. The 9xr still failed to detect the signal. While the 9XR was powered on and had the trainer cord plugged in and the PCTx was sending a signal, I measured the AC voltage of the PPM and...

I've built the circuit and attached it in-line between the PCTx and the JR cord. I'm getting 0.00 voltage from it. I've got a good ppm voltage to the "buffer" board (0.46v) but nothing after it. It's possible my circuit is screwed up, how would I test my circuit to see where the problem is...

PCTx AC Voltage changes from 0.40 to 0.75 depending on servo position.

No, I don't have an oscilloscope, but I have a multimeter and a "can-do" attitude.

I did some more testing today after making my own JR trainer cord and soldering it to the PCTx. I can now send PPM info to the JR F400 from the PCTX and it's 100% functional. Control surfaces function appropriately. If I take that cord and plug it into the 9XR there is no response from the 9XR. The ...

I followed your steps and the CAL numbers move (once calibrated) normally without the TRN switch held down. If I hold the TRN switch down, the CAL numbers don't change. Is that normal? If I reattach the module, the CAL numbers move normally again without a trainer cord. I don't understand what's goi...

Is there any way to test that the trainer port is operating properly?

Hello everybody. I'm having problems getting my 9XR to receive inputs from the trainer port. I just purchased my 9XR about a month ago. I haven't modded it in any way. I have the EZUHF JR module installed in the module bay. In RADIO SETUP page 1/5 Enable PPMSIM is ON In SETUP page 2/11 I have "...
