Walthers Mainline GE ES44 Evolution Series GEVO Diesel Locomotive With Digitrax DCS52
A reader posted this question on our YouTube Channel. Please add your suggestions below using the COMMENTS tag.
“I recently purchased a Walthers Mainline GE ES44 Evolution Series GEVO diesel locomotive with DCC and sound. I am currently facing an issue when attempting to change the short address (*CV1*) from the default value of 3 to another number. I am using a Digitrax DCS52 (Zephyr Express). When I attempt to write a new value to CV1, the system shows the operation as “Done,” but the locomotive still responds only to address 3. Additionally, when I use the CV programmer menu, it successfully reads CV values, but when I attempt to write, it shows ‘no pulse acknowledge.’ I’ve confirmed proper track and wheel contact, and the other decoders program is fine using the same system. Could you please advise if there is a known issue with CV writing on this unit or if any special programming method is required for this model?”

CV Programming Issue on New WalthersMainline GE ES44AC – Assistance Required
I recently purchased a WalthersMainline GE ES44AC UP #2540 (DCC and Sound) unit. I’m facing a persistent issue while trying to change the decoder address (CV1) from the default value of 3 using a Digitrax DCS52 (Zephyr Express). Although the system shows the operation as “Done,” the loco still responds only to address 3.
I’ve also tried programming using JMRI Decoder Pro, and while it reads CVs, it fails to write – showing “no pulse acknowledgment.” I purchased this new loco specifically to test this issue further.
Please note I am using an entirely new DCC setup, which includes:
1. Kato Unitrack
2. DCC Concepts Circuit Breaker
3. Digitrax DCS52 (Zephyr Express)
Locos tested:
1. WalthersMainline GE ES44AC UP #2540 – DCC & Sound (main issue)
2. Fleischmann #74106 DB BR03 111-2 – DCC Sound
3. Hornby R3392TTS Class 40 – TTS DCC Sound
The same issue appears across all models, but I’m especially concerned with the Walthers unit since it’s brand new.
what number are you trying to change it to? The short address can only be between 0 and 127.
And, usually, it’s the long address that people change. (And it must be 128 or higher)
Also, I’ve read that you can usually only change CV1 if you are in “program track” mode.
And if you are “programming on main” the system can tell you it’s done but in fact it isn’t. I’ve had that that experience.
