HENRY GELSTHORPE Posted January 13 Share Posted January 13 Trying to set up my RM TX16S to work with the GR6, this is for a KK Chief converted to e power.Now I have fitted a XJT frsky external module to the TX16s and disabled the internal MPM module in model setup menu. I have set both switches to off on the XJT module to put it in D16 mode, then still in model setup set external RF to XJT D16. What I am unsure about is the channel range setting "CH-CH16" (18ms) or should it be "CH-CH6"(9ms) and does it have any bearing on analog ver digital servos connected to the receiver?

John Wagg Posted January 13 Share Posted January 13 (edited) My logic is to set the lower number of channels which allows the channels to be repeated quicker ? Edited January 13 by John Wagg Quote Link to comment Share on other sites More sharing options...
HENRY GELSTHORPE Posted January 13 Author Share Posted January 13 Thanks John, yes that makes sense, re the 18ms ver the 9ms figure, less channels transmitted = quicker servo update. Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted January 13 Share Posted January 13 Does the Archer receiver not require LBT? It may be that your external module does not have LBT unless the firmware has been updated to include it. If not, use the internal module which certainly can be updated to LBT.

RottenRow Posted January 13 Share Posted January 13 The 9ms servo update rate should not be used with analogue servos. As you are also using an ESC, unless the manual for that states that a 9ms servo frame rate is acceptable I would set the bind to CH1 - 16 18ms. You won’t need the high update rate on the Chief. The GR6 rx has what is described as ‘smart matching’ of the protocol during the bind process. This presumably means that it will automatically detect the version of ACCST transmission (EU LBT or FCC, probably either V1 or V2). What exactly isn’t happening with the bind process here? Brian.

GrumpyGnome Posted January 14 Share Posted January 14 Yes, as long as the internal MPM has up to date firmware, it will bind to Archer plus rxs- I have this combo in one of my models. Quote Link to comment Share on other sites More sharing options...
John Wagg Posted January 14 Share Posted January 14 A query please - Why use the XJT external module ? Quote Link to comment Share on other sites More sharing options...
HENRY GELSTHORPE Posted January 14 Author Share Posted January 14 Thanks for the replies guys, using the XJT module as no tuning required, have successfully bound my Archer plus gr6 to the XJT module.I have a problem however trying to bind a G-RX8 that resides in my Graupner Cirrus glider, I think Rotten Rows post gives me a clue. The only way I can bind the G-RX8 is by using the internal MPM module, the XJT module has a LBT sticker on it. So does this mean that the G-RX8 is in need of some software update? 15 hours ago, RottenRow said: The 9ms servo update rate should not be used with analogue servos.

RottenRow Posted January 14 Share Posted January 14 Yes, sounds like the G-RX8 is on a different ACCST protocol to your XJT module. I run my D16 FrSky receivers on the excellent UNI firmware, which will bind to any of the four possible combinations that there are for ACCST. If there is a UNI firmware download available for the G-RX8 then loading that will solve this issue. I can look into that when I’m back later. Brian.

HENRY GELSTHORPE Posted January 14 Author Share Posted January 14 The XJT module was bought fairly recently so would have the latest LBT firmware, the Archer Gr6 was also a recent purchase so presumably has the latest firmware.The G-RX8 is a least 2 yrs old and maybe fcc firmware, however no marking on the receiver to support this possibility.

Mike Blandford Posted January 14 Share Posted January 14 I can confirm UNI firmware is available for the G-RX8. Using the XJT is a very good idea for FrSky protocols, rather than the MPM. All Tx modules have a "Unique ID", that is used when binding so that the bound Rx only responds to that Tx module. FrSky modules have a "Unique ID" that is allocated by FrSky, so all FrSky modules are unique. The MPM has a "Unique ID" (for FrSky protocols) that is derived from an ID in the processor. So, while this ID is probably different from the ID of other MPMs, it is NOT guaranteed to be different from official FrSky IDs. This means that if you use a FrSky protocol on the MPM and operate at the same time as a user of a FrSky module, it is possible both will have the same ID. Archer Plus receivers only work with the V2 version of ACCST. Mike 3 Quote Link to comment Share on other sites More sharing options...
RottenRow Posted January 14 Share Posted January 14 1 hour ago, Mike Blandford said: Archer Plus receivers only work with the V2 version of ACCST. That's useful information Mike, thank you. There is no mention of it in the 'manual' for the receivers nor the specifications. Not that I can see anyway. If Henry's G-RX8 doesn't have the little round EU LBT label on it then it's probably FCC and won't bind to his LBT tx without changing its firmware. The MPP module has different versions of ACCST-compatible firmware (FrSkyX2 is V2), both FCC and EU LBT, so the rx would bind with it in one of these modes. If you don't want to load the UNI firmware yourself, you can send the RX to T9 who will do it for a small fee plus return postage (or order something else at the same time and save the postage). As you have a genuine XJT module, it makes sense to use that wherever possible. Brian. Quote Link to comment Share on other sites More sharing options...
HENRY GELSTHORPE Posted January 14 Author Share Posted January 14 Just found a painless 360 video, going to give it a go, what could possibly go wrong !!!! Quote Link to comment Share on other sites More sharing options...
HENRY GELSTHORPE Posted January 14 Author Share Posted January 14 Managed to update the receiver using the Painless 360 video, I was lucky that I kept the s port lead and only needed to reverse the + & - wires . Bound now to the XJT module, so I have learned something new today. Thanks for all the help and suggestions. Henry 3 Quote Link to comment Share on other sites More sharing options...
