I have an NCE Power Pro-R System and it cannot read the CVs on the programming track of this one decoder and I cannot reset it either on the PT or main. Suggestions?
I get sounds and lights but the loco won’t move.
As always, thanks.
Could you possibly have F9 on? Drive hold. When you try to move does the engine notch up? Can you clear CV19 consist address? To reset is CV8=8 then cycle the power.
Pete.
Thanks, Pete, I tried all of the above. Horn, bell, and light work, I have sound, the engine sound does not notch up when I throttle up. I get "cannot read CVs when on the programming track.
You will have to check the motor connections. The decoder needs a motor load in order to read/write CVs.
Pete.
Hello All,
This might be slightly [#offtopic] but…
I bought a Roco EDK 750 Slewing Railway Crane.
This unit uses a ZIMO MX659N18 decoder for crane operation, sound, and independent propulsion functions.
With this decoder; to perform a full reset, not only does CV8=V8 but CV908=V8.
Using JMRI DecoderPro I added to my roster an entry of “Raw CVs 1-1024” decoder family.
This provides direct-to-CV programming and does access CV908.
I understand you are working with a LokSound V5 decoder but there might be a second CV that needs to be re-valued.
Short of purchasing a LokProgrammer, I would suggest contacting ESU directly and posing the question to them.
Hope this helps.
Post Script: The EDK 750 is an expensive item but worth every penny!
*H.T.H.- -*J.J.D.I.
Loksound 5 only needs the CV8 for a reset. I suspect a motor wire has come loose. The OP stated he could not read or write CVs. The decoder needs a motor draw or resistance across the orange and grey wires for read/write capability.
Pete.
I seem to be able to write CVs on the programming track and main. On the programming track, the first thing it says is it cannot read CVs, I then hit enter and the programming line appears at which time I can change CVs. The thing will not move. I must have inadvertently changed a CV along the way.
Does the locomotive jiggle when writing CVs? Do you have decoder Pro? Try reading all sheets and see if it walks down the track. Is it difficult to check the motor connections?
I’ve seen lots of my Digitrax, Soundtraxx and QSI/Paragon decoders do this on the programming track but I don’t recall any of my ESU decoders doing the “dance” during read or write operations. Maybe I just missed it.
Good Luck, Ed

The Loksound does it but not nearly as much as some other decoders. I did a WOW sound in a brass 2-8-0 a month ago and it rolled down the whole yard long program track. I ended up putting it the rollers. The Loksound 5 just wiggles a tiny bit. If you can take the shell off you can see the motor armature go round. I’m doing a Loksound 5 micro right now in an older P2K Alco S-1. I downloaded the sound file through the programmer and set up lights, horn, bell, and others using the programmer. Now I’m creating a roster file in decoder Pro. It takes about a half hour to read all sheets. This is the 12th sound decoder in six months. All that’s left is one E8 and a half dozen Alco RS units. Then I will have nothing but noisy locomotives.
Pete.
It does wiggle ever so slightly, does this mean anything? I thought I was seeing things as I thought it was not supposed to be able to move on the program track. I don’t have a programmer and I will try and get the shell off for a peek inside tomorrow.
I appreciate the help.
Had the engine been working normally at one time, or is this a new engine (or new decoder install)? If it worked at one time, I wonder if the engine was at some point a trailing unit in a consist set up through your DCC system (i.e. not through a CV setting). That might explain why it seems to respond up to a point, but won’t move.
Perhaps try changing the engine ID, like add one number to the current ID or just change the short address to 03 and long to 0003 and see if the engine responds to that. (As mentioned, you can change CVs even if you can’t read them back.)
If the locomotive is jiggling now then that would indicate the motor IS connected. Try what Stix posted above. If you have it on the roster of decoder Pro from the beginning then you could try the write all sheets to reload what was in before. Why it won’t read is a mystery.
Pete.
BTW quick and easy way to test for a loose motor connection without taking the engine apart is to try it on DC. Since it’s a dual-mode decoder it should run on DC but due to being a sound decoder may require maybe 9-10 volts before moving. It it moves even slowly in DC, then it’s a problem with a CV setting or (I suspect more likely) the engine is still set by your DCC system (not the decoder) to be part of a consist.
Well, it runs on DC, I have no consist in the system.
Even if the system has been purged of consist?
It is a Rapido F7B and was working and then it wasn’t. Horn, bell, and light still work so that tells me the addressing is OK.
Onward and upward, please keep the suggestions coming
ESU recommends using the program track (service mode) and Direct Mode to reset the decoder.
Writing a value of 8 to CV8 should work. If you have JMRI, it has a specific button for resetting an ESU decoder. You will have to determine the decoder model using New Loco - Read Type from Decoder.
Remember, a LokSound’s default address is not necessarily “3”. It could be any acceptable value.
ESU decoders are pretty complex and a bit different than other decoders, so maybe the best bet would be to find a friend or hobby shop that has an ESU LokProgrammer and review the settings using that.
This is a less basic thing to check on.
Did you change CV 31 or CV 32? CV 31 = 16 and CV 32 =0 if accessing CVs 1-255. Reference the Quick Start Guide.
The DCC Wiki page lead me to this. I wonder as my system was purchased in 2009. The letter is dated 2010.

Lee, I will take a look at CVs 31 and 32.
Perhaps I need one of these?

I feel like I am getting somewhere.
