I recently purchased a set of ABC units to be used in stations for realistic stopping in front of a red signal. My problem is that the loksound 4 sou d decoders will not accept a change of cv 27. All non sound decoders from various brands work fine. Any suggestions.?

You should be able to change CV27.  Are you using the LokProgrammer?  If you are, go to "decoder" "brake settings" and select the appropriate boxes and settings.

Hi Steve, no I use a digikeijs 5000 control unit linked to my laptop. I can change all other cv's like sound level, accelaration and braking. All other decoders accept either cv27 or cv51 to set ABC and all work fine. Do you need to change these cv's with a lokprogrammer in loksound decoders? Lokpilot 4 decoders acept cv27 wthout a problem. So I keep looking on the net. Next step contact ESU

It seems odd that you can't just write to the CV using any capable system, which the DR5000 undoubtedly is.  The Loksound manual certainly discusses changing CV27, and as it's a simple change the fact I can accomplish this on a Loksound V4 with both the LokProgrammer and ECoS shouldn't be a surprise.

Presumably you can read the CV27?  What value are you trying to write to the CV?  Are you doing this on a programming track?

We can certainly change CV27 in an LSv4 here with no problem.... we did it during testing many times.

Hi Steve, It is possible to read the cv27 = 0on a few decoders.
I have checked all esu decoders and noted the following
Roco BR01 ESU lokpilot can change cv27 to either 3 or 6 and the engine slows down when entering the ABC track section.
Roco BR18 ESU lokpilot read cv27=0 but will not be able to change The digikeijs software comes up with fail.
Roco BRE008 ESU lokpilot can change cv27 and engine slows down.
Roco railbus ESU loksound can read cv27=0 but will not change.
Roco BR52 ESU Loksound can read cv27=0 but not able to change.
engines with either a Zimo or Lenz decoders work fine.
May be there is a cv which needs to be changed to accept cv27 changes, but I cannot find it.
This is a challenge for me as it looks great when an engine correctly slows down for a red signal.
It seems to be a bit of a mistery for me
Kind regards, Frits

Hi Ahjay, some decoders will accept the change in cv27 and perfom as it should and some just come up with fail and remain at 0. May be there is another cv which needs to be changed.
I also will contact ESU and may be they can help. If I receive an answer, I will advise you of that. Kind regards, Frits

Its is not logical that two lokpilot V4 behave differently. (ie BR18 and BR01 instalaltion)

Have you tried simply doing the change on the main? Sometimes things that are in the install make programming track response reluctant on the programming track (permanently on Smoke units ir incandescent bulbs are often the cause) - but the decoder can / will respond OK to a POM Change.

Hi Ahjay,
 thanks for the prompt reply, but I may have to eat some humble pie. It could be that the decoders are the old v3.5 and after some further investigation on the net, these old ones do not work with a ABC unit.
The booklets however, which came with the engines are V4 booklets. I don't know how to find the difference between the two by just looking at them.   So it looks like some investments in later models sound decoders.
Kind regards, and thanks again for your help so far, Frits

Easy done... And its good that you have an answer!

All the best for the Christmas season

Ahjay

PS: Our current Zen Black has the best and most adjustable ABC operation available... far more accurate in stopping and slowing than any EU brand!

Thanks Ahjay, do you sell zen black sound decoders or just zen black standard decoders?. I have bought one zen black decoder and will install it in the br18.
