tractor_37260 Posted March 30, 2021 Share Posted March 30, 2021 Anyone know how to put a new 4 digit address on a Hornby R8249 8pin decoder using a Lenz Set 100 ? No matter what I try I keep getting error 2 ! Can't read/write anything on it ! TIA Ken Link to post Share on other sites More sharing options...
johnd Posted March 30, 2021 Share Posted March 30, 2021 Have you changed CV29 to allow a long address? Link to post Share on other sites More sharing options...

Is the loco on the programming track? 35 minutes ago, johnd said: Have you changed CV29 to allow a long address? You don't need to do this manually. When you set the address, the command station knows whether it's a short or long address and sets CV 29 automatically.

tractor_37260 Posted March 30, 2021 Author Share Posted March 30, 2021 (edited) Thanks for the replies. Can't access CV29..or any other CV's ? AFAIK bit 5 in CV29 requires changing from 0 to 1 to enable long addresses. Tried both the programming track and on the main. With other decoders the Lenz normally auto sets a long address once it's entered on the throttle. I seem to recall there was some sort of conflict when trying to program Hornby decoders with a Lenz ?

RMweb Gold RFS Posted March 30, 2021 RMweb Gold Share Posted March 30, 2021 I have the Lenz DCC system too and never had a problem programming R8249s although I don't have these decoders any more. As I said above, CV 29 will be set automatically according to the address you are using. Does the loco run OK on default address 3 which would prove the decoder is OK? Error code 2 usually means the decoder cannot be found, or your programming track isn't wired up correctly. Link to post Share on other sites More sharing options...

Error code 2 usually means the decoder cannot be found, or your programming track isn't wired up correctly. Loco runs just fine and lights work OK on address 03. Programming track works fine with Loksound/Lenz and Hatton's decoders but not this R8429.....just constant error 2's.....

RMweb Premium New Haven Neil Posted March 30, 2021 RMweb Premium Share Posted March 30, 2021 Odd. I have a Lenz 100 and do have some R8249's, I find them OK in diesels with flywheel drives Never had the Err02 with them. Duff decoder? Link to post Share on other sites More sharing options...

As a above decoder works OK on address 03, but can't read or write an address on the programming track. I don't normally use Hornby decoders, but it's the only 8 pin one I have small enough to fit into the chassis slot in a new Hornby 87. Did try other decoders on top of the circuit board but body would not fit back on. Also looking at perhaps fitting a different decoder where the recess for a speaker is cut and extending the wiring.

long island jack Posted March 31, 2021 Share Posted March 31, 2021 Try page mode on the lenz 100 Link to post Share on other sites More sharing options...
Dieselbob Posted March 31, 2021 Share Posted March 31, 2021 Have you tried resetting the decoder to factory settings. Change the value of CV8 to 08. if that doesn't work then there are plenty of small decoders around, Digitrax DZ126PS is but one. Just seems to be a problem getting stuff at the moment probably covid's to blame. cheers Bob Link to post Share on other sites More sharing options...
RMweb Premium newbryford Posted March 31, 2021 RMweb Premium Share Posted March 31, 2021 I've had some Hornby TTS decoders that wouldn't address on the program track - I had to use Program on the Main. Which is not good as I can't read the address on the program track! Link to post Share on other sites More sharing options...

You can do POM address changing as long as you know the address........ Which you need to know when doing any POM anyway. Although some systems/decoders may not allow address changing via POM.

I'm not near my Lenz set and can't remember the exact key press, but using +/- keys will cycle through the basic cvs - accel/decel/address etc. Then enter the new value. As I said - I'm not too sure if the Lenz may allow this - it may have been altered on the last update of the set100.. but you can alter CVs - so may be able to calculate the long address for Cv17/18 and alter Cv29 to use a long address. I know I can change the address POM on a NCE Powercab. 1 Link to post Share on other sites More sharing options...
long island jack Posted March 31, 2021 Share Posted March 31, 2021 (edited) I'm taking it, by all the question you don't have a manual for the lenz 100. use page mode same as cv mode page 55 https://www.dccconcepts.com/manual/lenz-owners-manual-lh100-throttle-handset/ Edited March 31, 2021 by long island jack Link to post Share on other sites More sharing options...
smokebox Posted March 31, 2021 Share Posted March 31, 2021 Is the op absolutely certain that it an R8249 decoder and not the earlier R8215 decoder which didn't support long addresses? The two decoders look identical apart from (possibly) different colour paint blobs on the main chip. Link to post Share on other sites More sharing options...

Yep definitely an R8249 with a BLUE spot. 1 Link to post Share on other sites More sharing options...
long island jack Posted March 31, 2021 Share Posted March 31, 2021 think your going to have to do cv29,then cv17,18,if that's how i read the instruction, cv1 only excepts #1-127,try putting a 2 digit number ie 87,if it works you'll have to go down the cv29 route file:///C:/Users/Ray/Downloads/R8249-Locomotive-Decoder-Leaflet%20(2).pdf Link to post Share on other sites More sharing options...
RAF96 Posted March 31, 2021 Share Posted March 31, 2021 If your controller supports it try REG mode. R8249 supports programming in all modes. Blue spot is definitely an R8249. Link to post Share on other sites More sharing options...

long island jack Posted March 31, 2021 Share Posted March 31, 2021 just tried my Peckett which i think has a R8249 in, on Programme track ,f8, DIR,ADR PUT #8720 in, worked, but when i came to change it back to #4,error 02, only way i could change number was a factory reset, try a reset then add your number Link to post Share on other sites More sharing options...
