First check that the lead to the transmitter has the pins reassigned, basically you drop the 5V line and cross connect the signal and ground

Look at the instruction sheet from the download link above

When that is done, do not switch the Tx on until after you have selected the .frk file. When the Tx turns on, it should then be detected.

Good luck

"Eyes they have but they see not"

After a conversation with my colleague, (who's Tx we're trying too update) I suggested there maybe a bad connection between the FUC3 and the Frsky Smart Port cable. Or one of the leads in the Smart Port cable may be faulty.

I was later rung back to be told that the leads between the FUC3 and the Smart Port cable did not match up.

In fact I had connected the cables together as in the "photo step1". The problem was the leads were reversed on our unit and if Smart Port cable module with the diode was joined as the photo then we had "no device found" msg

If however the diode module was reversed to the photo then everything worked OK.

Moral of the story is:

Don't rely on a photo, check the actual colour of the cables match to each other.

Tx now updated and older Rx also updated.

Thankyou.

Thanks to all. I'm trying to make a start, but hitting snags as expected. I received the three cables from T9 today.

Firstly, trying to download the firmwares from the FrSky site, I either get a page of this sort of stuff (3RŠQØÚ_h¸ie¹‚?0ÇÐÚÌa²ò¿Ó0;„Y¾ä该t–Ä•c~‰Féëkƒ'•ãIj(?íy'©*tO) or in one case I was given the X4R operators manual. Nothing that looks like a file of code.

Secondly, looking at the instructions on the leaflet "How-to for TFR4SB/ TFR8SB Firmware Upgrade" I found the item labelled "FUL" is not in this package. Where can I get that from?

Thirdly, looking at the instructions on the leaflet "How to upgrade FrSky Smart Port (S.Port) enabled products " I see the leads I have received match than interface lead shown except that the X4R has a little white SPort socket rather than a servo type one - I guess I'll have to make an interface lead like I did to make my pre-2015 X4R talk to the SmartPort sensors. Job for tomorrow!

Stuart could you give me details on the interface lead you made. I am trying to down grade a new x4r reciever. I have a frusb-3 upgrade cable which will not physically attach to the xr4. what else do i need.

Stuart, forgot to say, i don't have a s.port interface cable as show in step 2 of the how tp guide.

Hi, please can someone assist me?

I bought a taranis plux with a rx before Xmas and got it working after a struggle, I've now bought a load of new rx and find they don't work - not amused. Anyway, having hopefully worked out why they don't work, I now need to try and fix it presumably by upgrading my taranis and existing rx (X6R).

I get that I need the FUC-3 cable, but what other hardware do I need?

I have seen references to an SPC cable and that I'll need to make a diy cable. So that's 3 cables just to upgrade a tx internal XJT module?!!!

The DIY cable talks of removing and swapping wires from an extension lead around and yet the photos show a PCB so it's not really an extension lead then is it. Do you have to make that PCB - if so I'm stuffed. Where does the SPC cable come into this, I don't see how you can connect the FUC-3, diy cable and SPC cable all together! Why don't the photos show the extension lead without the PCB?

I'm rather confused here.

Thanks,

Jerry

Are you running the radio firmware as delivered or have you updated it to a later version of openTx?

I've built a version of openTx 2.0.15 that includes a feature to allow updating of the internal XJT and receivers directly from the radio.

I have just successfully "downgraded" a 2015 spec X4R to the old EU version.

Just made myself an adaptor lead between RX and update unit. Female to female extension, or sockets at both ends which ever way you choose to call it.

And just to be different, I updated all my Rx's and Tx to latest EU firmware yesterday. Today I have flown the 3 planes that have upgraded Rx's/Tx so I am happy!

I just found this worrying statement on the FrSky forum.

Hi, there's only D16-eu mode in EU Taranis+, if you want to use D8 OR LR12 mode, must use Non-Europe Taranis+.

Now this begs a few questions:-

Is this purely an OpenTx difference, i.e. if a brand new EU Taranis+ is upgraded to the latest version of OpenTx, will the D8 etc options return?

Or is it fixed in the hardware, for any Taranis+ that's shipped to be sold in Europe.If it's fixed in hardware, I assume that any new FrSky Tx would never work with D series receivers?

The FrSky thread is here

I think Mike Blandford cleared this up in the thread I started ( Taranis software updates) on 6 May. He says that the Frsky firmware does indeed only allow D16 mode but installing OpenTX firmware restores full functionality, including the ability to use D8 mode.

The EU XJT (ie RF transmission) update does not affect the way the application software treats the user choices. It seems OpenTX is the way to go. It seems strange that Frsky haven't adopted the same strategy and uncharacteristically have deliberately restricted user choice. Perhaps it's an unitended feature?

I would say that D8 telemetry is a bit of a grey area as the receivers need to transmit but are there are no upgrades to make them Look-Before-Transmit. Could it be that FrSky are side-stepping the issue by promoting D16 mode only? Existing (pre 2015) D8 receivers would be ok not using LBT under grandfather rights.

Its a while since I read the document, but as I recall, LBT only applies to devices with more than 10mW output. On 2.4 GHz, I believe the legal limit is 10mW for airborne transmitters. Therefore there should be no need to update D8 receivers using telemetry as they will be limited to 10mW.

Existing D8 transmitters are still legal under "grandfather rights". However, D8 presumably no longer meets ETSI 1.8.1 for 100mW devices, and is replaced by D16. This will be why FrSky have disabled D8 in new transmitters. There are, of course, ways around this, as others have pointed out.

Brussels strikes again!

My point is, that yes - I can go back and forth between EU and None EU Tx module firmware on my old Taranis. In either case I can use D8 mode and therefore use D series Receivers.

BUT - For compliance, have frSky had to produce a 2105 Taranis EU, that cannot be made to use D8 mode, whatever we try to do to it?

As far as I can see D series receivers can be upgraded to ETSI 328 1.8.1 by the customer.

This chart refers.

Chris: As far as I'm aware, the TX ETSI upgrade ONLY upgrades the D16 protocol. It doesn't touch an existing D8 protocol. If FrSky have stopped supplying the D8 protocol altogether in new transmitters (as I suspect they are legally obliged to do), then that is a problem. However, I would have thought that flashing with non-EU firmware would re-instate D8, and that then re-flashing with the 1.8.1 firmware would ONLY upgrade the D16 bit of it, leaving the D8 untouched.

This is a bit theoretical I'm afraid, as I only have an original Mk1 Taranis, so I can't speak from experience!

Its possible that FrSky have just removed the option from the menu, in which case simply re-installing the OpenTx firmware from the usual source, rather than from FrSky, might well restore it.

I can't find any firmware upgrades for D8 receivers covering ETSI 328 1.8.1, so I would interpret the chart as being wrong in indicating that they can be upgraded.

Bob, I've not gone down the path of trying to upgrade D series Rxs, just taken the chart info on trust but I don't think there's any reason to upgrade them anyway.

Looks like Peter is right & Frsky have removed D8 option from the menu but flashing from Open Tx doesn't remove it. Ref : **LINK**

straight from the horse's mouth then Pat. It's just an FrSky initiative.

I believe putting either openTx or ersky9x on to your Taranis will restore the D8 functionality on the internal XJT module.

Has anyone checked the options available in the FrSky EU firmware for the external module?

This should still have PPM as an option, and you should be able to use an external DJT module for 'D' series receivers.

Mike.
