Hi everyone,

I have experienced a rather odd scenario perhaps someone understands.

I use Lenz LS150 DCC decoders with 6 outputs for controlling Marklin solenoid motors. They come factory address 1-6 and you change address by pressing the button and then when you next activate a turnout on the address you want, the decoder accepts it is the first address.

Ie. press LS150 button, LED on, activate turnout on address 449 and the decoder takes 449 -454 as its 6 addresses and LED goes out.

Nice and easy.

Now I've bought 2 more of these for additional turnouts in my storage, first decoder I set address 449-454 straight away, all working.

However for the second decoder, I press the LED to change address but the LED does not go out after activating address 455. I try many different addresses at random but no matter what I try it does not accept any change.
I power cycle, decoder still activates on default address 1-6. I note however that on address 1 it sometimes does not respond to the command and takes a few presses.

I try factory reset, setting individual address for turnouts etc. but nothing works. You're thinking the decoder is faulty right? Me too!

I have experienced weird issues like this before with CS2 so decided last test I will try my ESU lokprogrammer.

I fire it up and just go to turnout control panel, activate programming mode and hey presto! Immediately accepts 455 as address. Always responds to all commands on 455-460.

I need to test the LS150 tonight with my CS2 but I am confident it will work without problem.

So the question is, which is to blame? The CS2 which does have a lot of decoders interacting with it - and yet the first LS150 programmed and worked instantly in the same scenario without problems.
The decoder then? Yet the LS150 worked flawlessly with the ESU lokprogrammer.

I wondered at issues with DCC primary/secondary addressing but note that the second LS150 would not accept any address in programming mode, including the same address that worked fine for the first LS150.

At least I have saved myself shipping a working decoder back to Germany.

Hi Eric,

Just a suggestion: You're in the middle of a block of 4 addresses, with value 455;
Maybe the CS2 has been designed referring to K83, which addresses block of 4 consecutive addresses ? and it is possible the CS considers 455 and 456 are also reserved...

Try address 457 with the CS2...

Cheers
