Thanks Mike, I'll give that a go tomorrow.

TVM, Luke

Ok, i just checked hobbyking's website. Takes 6v to 13v, I never realised that. I'm using a 9.9v LiFE so I'll connect from the battery voltage on the 9xtreme pad. I might be learning something here

Thanks again, Luke

Ah, you're right again. I had been trying the different settings (baudrate, com port etc) to see if i could get telemetry working. I literally tried all different settings and i remember changing that internal/external setting. if i dud manage to set it up with repaired or new internal module, what ...

Hi Joao.
the +, -, and ppm were all taken from rear of the 5 pins that protrude through the back to connect an external module

Hi Joao,

No LED at the front where the bind switch is, and no beeping etc.
OK, did a bit more probing. Only 1.3v going from the back board (5v and gnd) to the module. Took 5v and Ground from the 9xtreme board, and I have it working again??

Hi all, Back again. Did the soldering and checked for continuity, all OK. I connected the black and white wires as above, but the module seems to be dead now. Before I buy another, I found this http://smartieparts.com/shop/index.php?main_page=page&id=21 which suggests there's still mods to be do...

Again, Thanks to all for all the effort and time you've put in on my behalf

Mike.

To the pins at the side of the module (Tx and Rx), correct?

TVM, Luke

Mike.

Thanks Mike and everyone.

One last question, I did manage to solder those cut lines on the module board, so it's black and white wires to TX and RX - not TX and RX to 14 and 15?

Thanks All, Luke

OK Thanks to all. You've put enormous effort into fixing this for me but I haven't a clue at this stage how to go about installing for telemetry, so easier just to buy a new module :?: Am I right in thinking that if I buy the external module to plug in to the rear bay, I can just route the black and...

OK, I'll have a go.

No need to rejoin the board at the cut points, solder connections between ports 14 and 15 on 9xtreme and the rx and tx on the module?

Yes the two pins of COM2 are 5 volt tolerant. The absolute max rating is actually VDD+4.0V, so 7.3V, so normally OK to 6.0V. They do NOT like negative voltages though, still VSS(ground)-0.3V. Mike. When I said I needed the idiots guide to doing this I meant it :D . What does that answer mean? :oops:

Klaus and João,

Many thanks. I'll post the outcome as I can't be the first to go from that telemetry mod to the 9xtreme.

Luke

Oops, see another track(s) cut on front. Repair those too,

or

Just buy another module, fix the cut tracks on the mainboard, and connect black and white to tx and rx?

Hi Klaus Looks ok to me. I remeber i cut one track on the module and soldered a wire to the end points of it. Didnt touch the other side of the board 20151213_190828.jpg 20151213_190800.jpg 20151213_190727.jpg So, is it repair that track and the one on the mainboard, then connect the black and white...

What's the "via" and I'll check

Oh, you're right, that track is cut, I knew I had to do 2 cuts with that mod, thought both were on the mainboard, but it was one on each board.

Sorry, was on a 250km drive there. 20151213_181647.jpg You can see the scorch type marks where the wires were soldered. I'm confused again. Essentially, I have an unmodified frsky module (becaused everything is removed to make it stock), and a 9xtreme board. Is it not just a case of finding where th...

I just remembered, as part of that mod, i had to cut tracks on the 9x mainboard. Ive taken a pic of it

Thanks. My mistake, it appears it was modified so. So, i disconnect the red, yellow and black wires from thd 9x backboard, connect them to the 9xtreme module as you described above, and set to com 2. But where do i connect the black and white cables from the 9xtreme board, to the tx and rx side pins...

Did you use a level converter? This is important.. Can you post a picture of the module and how it was connected? was it connected as in the picture below? with the level converter? João Definitely didn't use a level converter or the two resistors. I can't find where i copied my hack from, but the ...

Was the DHT modified? or is it stock? João Hi joao, to my rescue again... Stock, i'd say. its connected to the FS TH9 BACK, using the red, yellow and black wires. I then soldered two cables to the back of the diy module, and ghese went to the 9x mainboard. The mainboard had been converted with the ...

I have the DHT DIY kit with Telemetry fitted . I have the black and white wire fitted to board in the frsky port so what is each wire? The black wire is data from the module (TX) to the 9Xtreme (SPort for an XJT). The white wire is data from the 9Xtreme to the module (RX). If using a DIY DHT module...

I know this is old but did you manage to hook a BT to the original 9X?

Rgds, Luke

The module IS powered from the battery voltage, not the 5V, so it is correct to have battery voltage on the middle pin of the module connector. Mike. I can only laugh at myself. I'm all day looking at this. I wonder would knitting be better for me :lol: I followed a few guides and they all said it ...

Any help here would be much appreciated. I was upgrading my 9x to a DHT internal module. Did all the soldering to the chip etc BUT on soldering the module to the backboard, I reversed the + and - :oops: :oops: :oops: I found on the Front board (the one with the on off switch) that I had fried a trac...

I just got Fatshark base. Really good. Electronicarc.com and fast delivery. The cable that comes with them is nice and neat really. Nice crisp pic in them and no light comes in through the sides etc. I'm thinking of getting the Dragon OSD+ v2. It needs a ppm channel on the receiver to operate. Am I ...

Hi again, another question. I'm looking to buy an OSD with RTH (return to home) function for FPV flying. I'm thinking of the Dragon OSD+ v2 (http://dragonlabseu.bigcartel.com/product/dragon-osd-v2-gps-and-current-sensor). It works using a channel on the receiver that receives PPM (not even sure what...

Gotcha,

Thanks again,

Luke

Brand new here so... I have read through any ER9X manual that I can find but cannot find a reference to what the safety switches do. My interest in this is I am wondering if they are related to failsafes. I know that the failsafe on Channel 3 (throttle) works when range becomes an issue but am wonde...
