I'm not 100% sure (Rob could confirm) but I don't think that was there when he asked. I looked for it and didn't see it, nor did any of us have our "has been thanked X times".

Thanks New to forums.
Need to find out if possible to change the names on the custom telem pages . roll on a updated manual :)

XJT module Telemetry:
The radio decides whether the telemetry baudrate is 57600 or 9600 depending on the protocol, 57600 for PXX and 9600 for PPM.

When XJT module sends telemetry S.Port, 57600 baud using X-series receivers, connect the TX wire (Black) to Pin 5 or the
external S.Port Pin and radio setting are then set to Protocol: PXX and Sub-Protocol: D16 with both dip switches OFF (down).

When using telemetry baudrate 57600 for D-series receivers, connect the TX wire (Black) to 5 Pin or the external S.Port Pin
and the radio setting are set to Protocol: PXX (XJT name change) and Sub-Protocol: D8 with both dip switches OFF (down).

To have the TSSI signal reporting using D-series receivers: connect the telemetry TX wire (Black) to the external Txd Pin
and the telemetry RX wire (White) to the external Rxd Pin,
then set radio setting Protocol to PPM (baudrate 9600) and Sub-Protocol: D8
with the XJT module's dip switch 1: ON (up) and dip switch 2: OFF (down).
These dip switch settings changes the XJT module into a DJT module.

using:
- Taranis Mavlink APM Pixhawk Telemetry adapter or APM MavLink to FrSky SmartPort Converter (Airborne Projects)
- XJT
- X8R
- Pixhawk
-9Xtreme
-Turnigy 9X

and Assuming that all is configured and connected the right way. (as I have try all ,all , all combinations)

There is no way to see the same telemetry data that I get on my tablet ?

What do you mean by "the same"?
Wrong values, or just not everything?

You can't have everything when using the adapters and going through FrSky modules, only the subset of things that is supported in FrSky telemetry.

Hi, Iam using the Teensy 3.2 connected to the minim osd and the telemetry port on the ARM 2.6.
I can receive, Sat’s, hdop, Lipo batt, amps, armed, revs, Alt, heading in degrees properly more. It’s just the labels in custom pages are not correct i.e. T1= sats. T2 = Armed. Fuel = HDOP.
Still you probably have no time to look at them and fly. Trying to find time to match up the sounds correctly. It may be couple of weeks before the weather may get better or the wind at least dies down.

One way of changing the names in the custom telemetry display is to use Scalers. These are available (in the GLOBALS menu), partly to be able to scale telemetry values, but they also include the option of defining a custom name.
Just set the source to the telemetry value, set the custom name, then use SC1 (or SC2 etc.) in the custom telemetry display.

Re: 9Xtreme Connecting XJT Module

Post by Paulusdw » Sat Dec 12, 2015 7:33 am

Can I confirm - because I'm stupid and after reading all the posts I am becoming more confused as I continue reading.

I would like to be able to use a FrSky DJT module in my 9Xtreme modified FS-TH9X. I would like to be able to swap modules depending on the model I am using, sometimes using the 2.4Ghz module that came with the FS-TH9X and sometimes using the FrSky. I would like to be able to take advantage of the telemetry on the FrSky.

Obviously an internal mod with no external wires would be ideal but would that allow me to swap back and fourth? In other words would soldering the wire onto the pin connector inside the transmitter affect the standard module?

Or should I have the wires hanging out the back?

It's probably very clear to nearly everyone else - but not to me.

Thank you for helping and if I need to do ANYTHING else to get the modules to work properly, please let me know.

Paul

Hi Paul,
My understanding is you can do the internal DJT mod and still use your stock 9X transmitter that came with your FS-TH9X radio.
The Danger is, if you use your modified DJT transmitter in a non-modified radio (like a Taranis) it will smoke it!

Because there are many 9x radio's and a lot of swapping around of transmitter in my RC Group
we use the Telemetry Cable through the 9x back-case so prevent Smoke happening :cry: .

If you are the only one using your equipment, its OK to do the internal DJT mod.

If you mod your DJT internally as shown here: viewtopic.php?f=95&t=3868&p=58136&hilit ... tky#p57047, then it is safe to use in a Taranis, as well as working on a 9Xtreme.

I will bring the cable through the case - I guess it's the easiest method.

Could you please confirm where the cable is connected to the 9Xtreme board and where on the DJT - it's just so I am certain what to do - there seems so many conflicting bits of information around.

Sorry to be a pest.

Hi Paul,
You may find the the Black and White telemetry wire is to short.
So you may need to add more wire to these telemetry wires.
I added about 2 inches to mine.

Just make a short Jst male 2 pin to pigtail solder adapter. The JST will plug into the B&W cable connector end connecting to the black wire connection. That way you can just unplug it if you want to separate the case halves.

Using both JST pins and the 2 wires, this could also be used as a way to use the through the case hole to the xjt rear data connector. Then again, a good way to disconnect the case halves. No reason to home run the B&W wires to the xjt or djt rear data connector from the 9XT board.
Just make a short make pin JST to a female 2 pin servo connector. If you use a 3 pin servo connector, just insert 2 pins. That or sand off one pin she'll to make a 2 pin.
Make the case hole just big enough to clear the 2 wires your using. I crimp on my own servo connectors so I pass one wire with pin at a time through a hole and then put the shell on. No reason to make a big hole to pass a connector through.
When I wire up anything with case halves and interconnect wiring, I try and use disconnects. So nice to work on.

This picture show some more supporting 9Xtreme Expansion Grid Pad connections.
Made edit to the wording in this picture Dec. 18 ,2015.
9Xtreme Ex Grid pads_c.jpg
Added note: pin 11 "Battery Voltage" is switched power, which including the "soft power" switch.
This Voltage is then also switched to the Internal and External modules by transistors controlled by the processor.
Pin 9: (PPM/PXX) is the Internal module connection, Pin 7: + power and Pin 8: GND connection.

Just to say that the picture above is not my original picture that you can find on "my 9XT installation" thread. This one has the TX and RX swapped.
The black wire is the 9XT RX and connect to the RF module's TX pin. The white wire is the 9XT TX and connects to the RF module's RX pin if a D series, or left unconnected if the module is a XJT.

Hi João,
You are technically correct and we are saying the same thing, but in a different way.
To the why I say it this way is because Steven (s_mack) has in the past and is with his 9Xtreme board, indicates the telemetry wires
as they come from the module's Rxd and Txd pins.
I believe he is doing it this way so to help remove some of the confusion that has and can happen when installing the telemetry wires.
When Steven finished designing the 9Xtreme board, the TX and RX connection are on the opposite side from each other compared to his
discontinued TelemetrEZ board, which he has labeled his telemetry wires as they come from the modules, not as they really are from his
TelemetrEZ and the 9Xtreme boards.
To be consistent with Steven, to help keep confusion down, I have been describing as the wires connect to the module pins.
Note also that the telemetry wire colors are also opposite between the discontinued TelemetrEZ and the new 9Xtreme board.
So take note, the older photos of the discontinued TelemetrEZ Colored Wires to the modules (external DJT and XJT) are
opposite compared to the new 9Xtreme board to the external DJT and XJT modules.
We can not use the same photos for both boards, we have to use new photos with the new 9Xtreme boards.
When I discovered the difference, Steven and I had a lively discussion about this and when I understood from an engineering perspective why
the RX and TX had to be swapped, it made sense.
I was looking at it from a consumer point of view, as it was going to cause confusion and it has, but it has to be this way.

Here is a picture of how Steven labels the 9Xtreme board telemetry connections as the wires come labeled from the module's Rxd and Txd pins.

Re: 9Xtreme Connecting XJT Module

Post by jhsa » Fri Dec 18, 2015 3:02 am

It's still wrong.. That will confuse people as well ;)
Then you must say that the black wire must connect to the module's TX pin, instead of calling the wire itself TX. That will confuse people that are a bit more technical. For example, as far as I remember FRSKY did the same mistake on their serial adapter. I couldn't for the life of me update the D4R-II receiver until I have found that they named the pins wrong..

In this concrete case of the 9XT, you/we should not even mention what the wires are.. Just say that the black wire connects to the module's TX pin, and the white wire connects to the Module's RX pin should be enough and very clear. Like this you avoid confusion.. It doesn't matter what the wires are as long as the color is consistent. This would avoid confusion, because the ones that don't know, have the information they need to connect things right, and the ones who are more technical will assume that if the black wire connects to the TX pin, then must be RX. What I think confuses people is calling things the wrong name, as in the future, when people now a bit more, they will face contradictions because of the wrong information it was given to them in the past. And this happened to me. That is why I always try to provide the most correct information..
Just my 2 cents

Hi João,
I agree with you.
My Sky9x radio was the first radio which I connected the telemetry wires and it dose technically describes
the correct way to make the telemetry wire connections.
When I installed my first TelemetrEZ board in one of my 9x radio's, I found it did not work the same way
and when following Steven's instruction, then the telemetry work properly.
If Steven, when he adds to his 9Xtreme installation instructions for the telemetry wire connections,
to reflects the proper technical description, then I will be happy to change the wording.
I may have to change my 9Xtreme photos to match also, if when Steven writes his telemetry wire connection
instructions and if technically proper, then I can work on making the proper changes.
I am trying to have thing technically proper and avoid conflict and confusion, but also bend when I have to,
to help make thing come out correctly.
Steven may be on holiday until next year maybe ?

The sentence you wrote doesn't translate into an electronic standard, no. Logic falls apart too, because it depends on perspective. I feel like we've been through this before.

We're talking about the 2-wire connector on the 9Xtreme labelled as "FrSky". There's a pin 1 and a pin 2 (which is which is academic for now). One is "tx", one is "rx"... but which is which? That depends. It is a connector, not a chip. The 9Xtreme chip's "tx" is connected to (let's say) pin 1. That same pin, however, connects ultimately to the transmitter's "rx", right? The connector is merely a conduit, so it is simultaneously both a "tx" and "rx" depending on the perspective. How should it be labelled? It is clear YOU think it should be labeled from the perspective of the chip. And that's perfectly understandable since the connector is on the same board as the chip. But is that "standard"? Hardly. Let's think about old school computers (pre-usb) that had a "mouse" input. Clearly the label of the connector is talking about the thing on the other end of the wire, not whatever is inside the PC. There's no "mouse" inside there. Same with "keyboard". in fact, most electronics label connectors based on what is being plugged in, not what's going on in the device itself. From that perspective, it makes more sense to call that pin "rx" based on what is being plugged into that pin. That's how I did it with the TelemetrEZ.

I accept that it is fairly conventional for a device's pins to be labelled from the perspective of itself... however, I don't think it is at all standard that it extends to connectors downstream. That pin is, in fact, connected just as much to an "rx" as it is to a "tx". Another analogy: When a phone call is happening and Joe is talking and Sally is listening, you can call Joe the "tx" and Sally the "rx" but the phone wire is... what?

I'm not saying you're wrong. I'm just saying it IS ambiguous no matter which way you label it. Which is why I didn't.

Thankfully, unlike a battery connection there is no catastrophic harm in getting it "wrong".
