John Burrows Posted August 30, 2018 Share Posted August 30, 2018 Hello, I am returning to model flying (again) after a 5 year break, started out with single channel push button in the late 60's.....Skyleader 6 channel in the 70's (remember those??) etc... I had a lot of fun with my JR PCM9X a few years ago and now would like to move on to 2.4 Ghz, BUT.. what a nightmare!! Nothing seems to work together and I am begining to wonder if it is really worth the hassle. I don't feel inclined to spend a huge amount of money on a new system, and I like the sticks on my JR. My boss has lent me a Futaba but I really don't like the feel of it and want to use my JR by changing the TX module to a 2.4 Ghz. Got me a FR-Sky module that seems to be OK but I can't get it to bind with the RX. (also FR-Sky and on paper should work) Whatever happened to plug and play?

john stones 1 - Moderator Posted September 2, 2018 Share Posted September 2, 2018 Hello John. I have the frsky module in a JR 9x, works fine, you've probably missed or not understood something in the bumf, post what you're using n someone will sort it.

Robert Parker Posted September 2, 2018 Share Posted September 2, 2018 Hi John, Welcome back to our hobby. I have recently moved from a JR PCM9X which had a 2.4 module which worked on Spektrum DSM2 and DSMX receivers. However, I was concerned about it after losing a few models and went over to a Spektrum DX9 which only works with DSMX receivers not had any issues since. I'm affriad the days of mix and match with receivers anf TX's has gone. Al's hobbies still sells them I believe. Regards Robert Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted September 2, 2018 Share Posted September 2, 2018 hello and welcome from me john,don't be put off by the current tech...its much more easier nower days than times past. Have a look at what other people are using for TX/RX's, the equip today is really easy to use and set up as is the selection of models. Regards your FR-Sky gear I don't use or know much about -but there are lots of users on the forum here who will advise you...have fun. ken anderson...ne...1.... welcome dept.

john stones 1 - Moderator Posted September 2, 2018 Share Posted September 2, 2018 I disagree, the frsky Jr module and the accst rx's are fine. It's not mix and match once modules replaced.

I'm in a similar situation to you, but I'm learning fast, thanks to the help from the internet and especially this forum. I've had exactly the sort of problems that you've described. 2.4ghz is extremely complicated compared with the old 35 mhz. There's loads of compatibility issues waiting to bite you. The best is to buy a transmitter and receiver as a set, then you know that they're going to work together. I'll take a guess that your issue is that you bought the non-Euro transmitter module and a Euro receiver. You can probably adjust either of them by flashing the firmware. If you show us exactly what you have and where you got them from, we can probably help. PS. You need to be an FMR because you're going to be burried under acronyms.

Bob Cotsford Posted September 2, 2018 Share Posted September 2, 2018 It would help to know which version of module and receiver won't bind, and how old each of the FrSky elements are. How are you confirming that the module is working ok? If you post which part of the country you are in it may be that there is someone local with FrSky experience who could help you.

john stones 1 - Moderator Posted September 2, 2018 Share Posted September 2, 2018 Could be a number of things, I sat scratching my head when I first bought mine, not understood bind procedure, not got the switch on back of module set correct for the rx, more info will get it sorted.

John Burrows Posted September 2, 2018 Author Share Posted September 2, 2018 Hi All, Many thanks for your replies, I am using a FR-Sky XJT module with EU LBT firmware, and at this time have a V8FR-II Rx, all ACCST, all new. (got a D4R-II coming next week as that was the FR-Sky suggestion. Switches are set correctly on the Tx module, Tx is set to PPM, The LED on the TX module comes on OK and it Seems to be doing what it supposed to.... I am in Redditch in Worcestershire, any more suggestions?? Edited By John Burrows on 02/09/2018 11:22:41 Quote Link to comment Share on other sites More sharing options...
Mike Blandford Posted September 2, 2018 Share Posted September 2, 2018 You need to link the channel 1 and 2 outputs of the Rx, then power it on. I think the LEDs should not be flashing at this stage. With the module on the Tx with SW1 on and SW2 off, power on while holding the bind button pressed. The red led should be flashing and the module beeping. The bind to the Rx should then take place, and the Rx LED(s) should then flash to indicate this has happened. Now power both Tx and Rx off, then back on, you should then have control.

john stones 1 - Moderator Posted September 2, 2018 Share Posted September 2, 2018 XJT..can support can support V+D rx's If flashed with non EU firmware, is it this problem ? Bumf, receiver compatibilities Quote Link to comment Share on other sites More sharing options...
John Burrows Posted September 2, 2018 Author Share Posted September 2, 2018 Hi All, Just tried it again, with the jumper in place and it has worked, not sure why as I haven't done anything different, switches in the same position etc.... But it seems OK. Will try a range check to confirm it but the Rx is showing a green LED (for the first time) and it works OK on the bench.. Result!! Thanks everybody, for your support.

I think that is incorrect. The XJT supports 'D' and V-II" receivers whether it has EU LBT firmware or international firmware, I just double checked by binding a LBT XJT to a D8R-II. Where there may be a confusion is on FrSky transmitters running openTx (and possibly FrOS), if the Tx itself (not the module) has EU firmware, then the 'D' option is not available for selection in the menus.

Bob Cotsford Posted September 2, 2018 Share Posted September 2, 2018 John, the V series receiver that you have defaults to an older FrSky protocol, binding with the jumper sets it to the D8 protocol that can talk to your module. It's really down to the rapid rate of development of 2.4GHz systems which means that even within any one manufacturers products there can be compatability issues between different generations. If you stick with D or X series receivers you should be ok. Mike, doesn't LBT only affect D16 protocol use?

Yes, but as I said, you may find you cannot select the D8 protocol, particularly on an internal module in a FrSky transmitter. Mike Quote Link to comment Share on other sites More sharing options...

Martin Harris - Moderator Posted September 2, 2018 Share Posted September 2, 2018 I'm so glad that my system just wants a shorting plug applied before power up to any of the various receivers I've bought (or could have bought) since adopting it in 2009, to bind them. All these receivers have worked seamlessly with a transmitter module and then with a dedicated transmitter through various evolutions of software to both improve its capabilities and comply with changing standards. I can only look at some of the efforts by other manufacturers to tie their users into knots with a little detached amusement. Posted by Dave Hess on 02/09/2018 09:38:30: PS. You need to be an FMR because you're going to be burried under acronyms. BTW, WTH is an FMR? These TLAs are a real pain at times. Possibilities I could find in a Google search included Friends of the Molalla River which seemed as close as any of the other 36 suggestions shown: Copyright 1988-2018 AcronymFinder.com, All rights reserved.
