OpenTx 2.1.0 and later


The JR module that we sell can be set to output XJT D16 protocol necessary for the Taranis, Horus, and other transmitters that can run the OpenTx firmware.

When OpenTx v2.1.0 firmware was released, it no longer worked with our original JR module in XJT D16 mode. That has been fixed with firmware update (v4.3) for our JR modules. Please note that none of our transmitter modules (except the A9) are officially in-field flashable using our XDP programmer (or the Serial w/Nano or RFU, which can emulate the XDP). If your module does not have a flashable CPU, or you don't have what's necessary to flash our modules, it would have to be returned to us to be disassembled, reprogrammed, and re-assembled. There is a cost associated with this, but it is a reduced cost compared to our normal firmware update (where you can send in any number of pieces to be upgraded for $39.95 + shipping). The cost for the JR module (only) upgrade is $9.95 + shipping.

To use our JR module with an OpenTx based transmitter you need to change the module's input mode to 2. To do that, put the module into push button programming mode (like for setting the power, hopping, and input mode). Red=power, green=hopping mode, orange = input mode. The default input mode is 1 flash (PPM). Set it to 2 flashes (XJT).

To use our JR module with OpenTx you must set the OpenTx based transmitter with these settings:
  • Set the Internal RF to OFF
  • Set the External RF to XJT D16
  • Set the failsafe to RECEIVER

Hi Jim,

I just purchased a Horus X10, with Open Tx 2.2.1 .
If I purchase a new Jr Tx module from you today, will it have the new firmware that will work with the Open TX?

Yes! I have updated this thread!

Okay, can someone please walk me through all the changes that need to be made to make the new JR module work with the Horus X10? In the Horus settings, I have the internal module set to off, External set to XJT 16 and failsafe to Receiver. I can't find details on how to set the XPS module to XJT mode. The manuals don't mention modulation mode, only that it will be added in the future. The RX and TX will not bind despite being set into binding mode. Please make a sticky of all of the settings in the Open TX as well as the XPS module that need to be set and how to do it.

See first post of this thread. I tested the modules we sent to you. I almost left them in input mode 2, but I was not sure what Tx you were going to be using so I set them back to input mode 1 before they were shipped.

Flashing JR Module firmware for Horus transmitter


I am confused and that's not hard, In another post here you say not to update Open tx 2.1.0 and later as it will not work with the Horus X12s firmware in Open TX.
So are things resolved with the Horus X12s now and if I update the JR module with V4.3 it will work?
I had a look at the firmware down loads for XPS and V4.3 does not mention Frsky (taranis) at all only V4.6 to V5.8 mention taranis.
Can you please tell me what Version of XPS firmware I should flash to the JR module for the HorusX12s using open TX 2.1.0 and later.
I bound to the XPS JR module with XPD and it is flashable V4.2 and the option to upgrade firmware tab is there.
Do I down load the upgrade and save it on my hard drive then search for it through XDP ?

v4.3 is the firmware version for the XtremeLink module. The v4.6 to v5.8 you see is the version of the updater program itself!

You must have firmware version 4.3 flashed on your JR XtremeLink module in order to use OpenTx 2.1.1 or later.

The updater program is what you download and run. It contains the latest firmware for every product we make. When you run the updater program it will tell you what XtremeLink device it found, what the current firmware version is and what firmware version you can update it to.

My TX module is flashable and has V4.2, how do I update the firmware on it via XPD.
Is there a tutorial on this. Which version updater do I use?
I am completely confused with this updater version, am I correct that I can update with updater v5.8 which has the 4.3 firmware required for open TX 2.1.1

Firmware upgrade


I downloaded updaterV5.7 and put module in programming mode orange led and the updater found the TX and updated to V4.3 cool!
Not as hard as I thought.
The updater version and the firmware version numbers were a bit confusing to me but all good.

I am glad you got it sorted out! Every product we make has a different firmware version. The updater program contains the latest version of firmware for each of those products. The download page has info about each revision of the updater, showing what version of firmware the updater will update each product to.
