First of all I’m new to the forums as a poster, but had got a great deal of knowledge so far. However a little problem has presented itself. I recently have change era’s and have got a zephyr for y command station and it works great. I also have a Heavy Mtn from bachmann and it works great on the factory progrmmed 03 address, however when I follow the instructions to change the address the Z reads back that no decoder is detected. But it does have one and works great on 03. Any suggestions on how to fix the issue? I also have a utility throttle at my disposal. I also know its not operator error as I have changed all of my other loco’s addresses.
Thanks, Rick.
The bottom-end Lenz decoder does not support CV read back, and the Zephyr is telling you this.
Unfortunately, you will have to program CV17, 18 then 29 in OPs mode to get this decoder to change addy to 4 digit. Lenz decoders do NOT like Page mode programming (unless you are using a DB150).
Note that the Zephyr will program CV29 then CV17,18 when you use the console address change feature. When it changes CV29 first, then the system will be talking to the wrong decoder in OPs mode.

The cheapy low end decoders also don;t seem to put enough of a load onthe program track for the command station to see the acknowledgement pulses (they must pulse the function instead of themotor or something), so it sometimes helps to put a 1K resistor across the rails of the program track when trying to program such decoders.
