PatMc Posted January 31, 2018 Share Posted January 31, 2018 I know that the manual says D8 mode isn't accessible with the Horus X12S (EU version) using the internal RF module. Is this strictly true when using OpenTx ? Can D8 be accessed in the same manner as the Taranis with EU firmware ? Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted January 31, 2018 Share Posted January 31, 2018 It is accessible, but of course you'd be Euro set rule breaking, so would not do it, would not even think about it, never, no way, absolutely not, we all know this. Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted January 31, 2018 Share Posted January 31, 2018 It doesn't matter if you're on OpenTX or FrOS - if you flash the RF section with the rest-of-world firmware (which will have to be done with FrOS), you can transmit in D8 mode in either operating system.

Andy Meade Posted January 31, 2018 Share Posted January 31, 2018 Yes, just bind in D8 mode, but I know for sure that option is not there on FrOS EU version. I can't see how "illegal" it is, seeing as no one has come round to my house asking for my old DFT modules, but understand legislation is there to stop people selling new items without the "LBT" firmware. LBT is listen before transmit, which means non-euro and older kit will transmit on a frequency when turned on without checking to see if that specific frequency is clear or not. A particular problem in modern frequency-hopping systems. Edited By Andy Meade on 31/01/2018 15:11:17 Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted January 31, 2018 Share Posted January 31, 2018 I think you need to just clear the 'EU' checkbox in Companion radio settings before downloading and installing OpenTX to make D8 mode available. I'm pretty sure that was all I did. Quote Link to comment Share on other sites More sharing options...

PatMc Posted January 31, 2018 Author Share Posted January 31, 2018 Bob, I'm thinking of getting a Horus X12S [or possibly a X10s] so just to be clear - are you saying that you have a Horus using EU firmware and with D8 mode capability ?

PatMc Posted January 31, 2018 Author Share Posted January 31, 2018 Thanks Bob. Can I ask which Horus you have ? I'm unclear if the EU firmware on different versions of the Horus will make any difference to the D8 mode capability. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted January 31, 2018 Share Posted January 31, 2018 I've got an X12, I understand that they all use the same iXJT module so the rf side of things should be the same. Quote Link to comment Share on other sites More sharing options...

Like Bob I've also got an X12, but its certainly my understanding that the module is the same, only the X10 has twin internal aerials (want one!!!). I've just checked the X10/X10S on the Companion and simulator, and without the EU box ticked you can select D8 mode. As I have read before, it appears FrSky do not lock their internal iXJT module, so OpenTX can access the D8 mode. To be fully certain, why not ring T9 Hobbysport.

PatMc Posted January 31, 2018 Author Share Posted January 31, 2018 Thanks Bob & Andy, more questions - I'm using OpenTx 2.1.9 on the Taranis, there's no option for any version of Horus in the Settings of Companion. Am I right in assuming that I need to download the 2.2.0 or 2.2.1 to play with a virtual Horus [Ooo missus!] & that I can run both versions of Companion in parallel? Quote Link to comment Share on other sites More sharing options...
Andy48 Posted January 31, 2018 Share Posted January 31, 2018 Yes you need to be on 2.2. This is the first implementation for the Horus. Yes you can run both versions, however, set up a different file location for 2.2 as you will need to download the 2.2 SD card for the Companion. 2.2 has a number of changes. The first is eepe files have gone, now they are otx. The Companion will convert all your models, though you will need to check them. It gets the odd minor thing wrong. I'm still converting my models, and actually is a good time to have a clean-up and standardise. Some of my early model settings certainly needed a bit of tweaking.

Geoff S Posted January 31, 2018 Share Posted January 31, 2018 Someone had a Horus at the indoor flying session this evening so I asked him if he could use D8 mode even though he was on the EU (LBT) RF s/w and he confirmed that he could because he'd adjusted the s/w. So it's certainly possible. I really wish you'd not mentioned it Pat. They do look very desirable but I'm on the second transmitter (Taranis) that would last me forever (the first was my Multiplex 3030).

PatMc Posted April 14, 2018 Author Share Posted April 14, 2018 I'm about to flash my X12S it to OpenTx & a little nervous about the proccess so please bear with me if the answers to my questions are a obvious. The FrOS installed is version 1.2.25 latest version seems to be 1.5.04, is it advisable to upgrade the FrOS to this before begining the change over to OpenTx ? If so can I assume that I can jump straight to 1.5.04 & don't need to upgrade to any of the other versions first ? Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted April 14, 2018 Share Posted April 14, 2018 Apparently anything over 1.2.23 is good to go Pat. As far as I can make out there no iXJT rf module changes in later versions. Quote Link to comment Share on other sites More sharing options...
PatMc Posted April 14, 2018 Author Share Posted April 14, 2018 Bob, the reason I asked if the FrOS should be updated is due to the fiollowing quote from the final page of Martin's (Andy48 's) Horus documentation : Re-installing FrOS As the FrOS firmware contains the transmitting module firmware, if this ever needs updating, it is necessary to return to FrOS, upload the latest version then reinstall OpenTX. My reasoning is quite possibly (probably) flawed but I thought that by installing the latest FrOS firmware available before changing to OpenTx it might be more straightforward & could make the need to re-install it less likely at a later date.

Bob Cotsford Posted April 14, 2018 Share Posted April 14, 2018 Pat, as I said, as far as I'm aware 1.2.23 contains the last update to the tx rf module firmware. I don't think there is a problem with skipping FrOS versions should there be a need to update the rf firmware, if there is I'm in trouble as I have missed all update from 1.2.23 to 1.5.xx! If in doubt updating is probably the best policy. Martin/Andy, where are you when we need you Quote Link to comment Share on other sites More sharing options...
