nce newbie programing problem

[platerman]

I programed two engines with no trouble. The next one could not read cv's.Checked all the usual stuff: wiring, decoder wiring, track. All seemed okay. Then tried my MTH and the same thing. All of these engines programed okay with my Dynamis system. Please help,anybody. Thanks

5 amp system or PowerPro?

 WHich decoder int he one that won't read?

And which MTH? The older ones have very little to control under DCC. Over time they've updated the firmware to allow more control with DCC, these updates canbe applied to an older model but need a DCS system to do it, perhaps you LHS can help.

The OP's issue his clear.  He has a decoder which cannot be read by his controller.

But everything else is unclear.  Give us more info.

What type of NCE system are you using?

Are you trying to program on the programming track or the main line?

Which decoders can you program and which decoder can you not program?

How does the Dynamis system play a role in this situation?    Have you changed from Dynamis to NCE and now you have problems reading and programming a particular decoder?

Here's a little more info: I'm using a 5 amp power procab-r. I've tried using the programing track and the main track for programing. I programed the GP9 that came with the Dynamis system, and a Bachman Shay with the tsunami decoder, no problem. My Fox Valley Hiawatha with a tsunami decoder and my five MTH engines all purchased since 2010 get a "cannot read cv" message. I had all of these engines programed into the Dynamis system at one time. I do not have the radio system hooked up yet- I'm still tethered. Any suggestions? Thanks again.

I use the NCE 5 amp PH-Pro wireless as well.

Assuming the decoder is good and wired correctly and solidly, it sure definitely program on the main track.

On my programming track, I have installed a Power Pax Programming Track Booster to read some sound decoders.

The fact that the Tsunami decoder and the five MTH engines all get the "cannot read cv" message tells us that it is probbaly not the decoders.

My guess is that the programming track needs a booster to read the sound decoders.

But, you definitely should be able t program any loco on the main track.

Probably true in this case, but bad decoders do give the "cannot read CV" error message on the ProCab.

My guess is that the programming track needs a booster to read the sound decoders.

But, you definitely should be able t program any loco on the main track.

This is my guess also.  What the OP describes is typical for attempting to deal with sound decoders on the programming track without a booster.  Assuming he knows the addresses already in the decoders, he should be able to reprogram on the main.  If he needs a read back on anything though, he'll most likely need the programming track booster.

Hey Guys.

My Power Cab doesn't have a programing outlet and has never failed to program any of my decoders.

Question, is the programing outlet on the Power Pro less powerful than my Power Cab?

I have a programing track, but I just flip a switch to throw the Power Cab output from the main to the programing track.

Thanks

Lee,

The Power Cab comes with a little extra built-in "oomph" in programming track mode for the specific purpose of programming sound decoders.  Unless it was a bad decoder, I've never had a problem programing either sound or non-sound decoders with my Power Cab.
