Cant get your radio to work? General Hardware issues?

Taranis X9D schematic...

Postby citykid » Tue Oct 29, 2013 11:48 am

Sorry if this is a repeat request!

Does anyone have a circuit diagram for the Taranis TX board?

I'm looking for where the telemetry data breaks out....

Cheers!

I think frsky didn't release it and I doubt they ever will :(

No, it hasn't been released. What information exactly are you interested in?
If you look at the inbuilt XJT module, you will see on the left side a 4-pin and a 3-pin place for headers. These are the telemetry headers of the external XJT module and may well have the telemetry data available on them.

@MikeB

Are you saying that inside the Taranis X9D unit is an inbuilt XJT module, and that has the serial channel connections on it?

Please clarify...

Thanks!

@Kilrah

Thanks for that!

Any idea on the voltage level? 3v3 / 5v / +/- 12v(!)....? Also the baudrate? 9600 8N1....?

So I guess if I stick serial data in at the model end, it will come out at the X9D end....?

Thanks for you help on this!

Same as the DxT modules for the serial port, just look at the published specs and protocol on FrSky's website. Data is not transmitted transparently, some framing is added.
From users' observations the serial port on the XJT is however only active when using D type receivers. When using X receivers the telemetry data is only available on the smart port, for which no documentation is available.

@Kilrah

Sorry if I persist on this topic...

So if I connect a microcontroller to the Serial Port of the XJT module and I send some mavlink messages, these messages will be sent to the remote receiver (for example: D8R-II)? Or I simply have to convert the messages into PPM and then send them to XJT's PPM input?

Could you answer to my questions, please? Beacuse I going crazy on configuring my taranis x9d to send data from an external microcontroller (Arduino or PIC) to a remote D receiver.

Thank you in advance...

The XJT will not transmit anything that comes on the serial port, and D receivers don't support any uplink besides control data.
To upload data you would need to use X receivers, and the XJT's smart port.

FrSky are releasing "S-Port to UART" modules you can plug on each side's smart port and which make up a transparent bidirectional UART data link. BUT the data rate is very low, max. 90 bytes per second for bidirectional comms or 160 for unidirectional.

What exactly are you actually trying to achieve? With that information we may be able to suggest possibilities.

Thank for your replies...

Here you are my idea:

I bought an Hexacopter a little time ago and I've played with it using the taranis x9d radio! I've found it great!!!

After doing it I thought to implement a semi-automatic control for the hexa.
So I'd like to connect, in some way, my serial port on a PC or on a microcontroller (Arduino or PIC) to the serial port which is on the built in XJT module into the taranis x9d radio, in this way I'm going to use its antenna and send to the hexa some mavlink messages to arm it, disarm it, increase the throttle value, and so on...

(1) I don't know now if it is possible to send those messages immediately from the serial port on the XJT module and then wait them to be transmitted. (2) An other solution might be, if possible, to encode the messages into a PPM signal and then send it to the PPM input pin of the built-in XJT module (by using this solution I won't use the serial port anymore, but only a micro which will encode the messages into a PPM signal).

Is this idea possible, by using:
- a taranis x9d radio
- a D8R-II plus receiver
- a micro to encode the messages to PPM

Please?

I hope my description to clarify you and help you to give me some suggestions! :)

Thank you again for your attention and your answers....
