Hornby P2 will no longer program

[RAF96]

We'd just need the instructions from Hornby.

What instructions would you expect. Reset CV8 to value 8 a few times to make sure it sticks. Check it works, then readdress it to suit.

if you have access to a suitable PC you could do worse than get hold of an Arduino Mega, a generic motor shield and a USB lead, then install JMRI - this will give you something able to fully edit and interrogate DCC decoders, as well as drive them.

assembling it sounds scary but its not, DCC-EX has an installer than will configure the software on the arduino, JMRI is... interesting.. but Decoder Pro isn't that hard to use and there are plenty of videos

the hardware is also decently cheap on eBay. not hard if the PC is nowhere near the layout to have one of these beasties on a desk connected to a length of set track straight either

This is a fun idea. I watched a few videos and don't have a 100 percent grasp on the steps of assembley/ installing software but could be an interesting project. Im going to look further at this.

Buckambool Trains down south sell Zimo decoders. If an MX600 would fit, you could try one of those in there. These ain't the cheapest, but really good value. If one of these works then you could take it up with Hornby.

A bit of a trek from Browns Plains to us, but a nice day out too. We're in England at the moment, but coming home soon. I have a Lenz system that can do all the reading/writing that you want. We'd just need the instructions from Hornby.

Let us know if you fancy a drive.

I don't want to impose but if you're comfortable when you're back I'd be pleased to come for a drive up.
I looked up the Zimo decoders through Buckambool trains and they dont seem expensive. I may well purchase these to get a few of the DCC ready locos I've got converted over.
Ultimately if the P2 decoder can be reset, saving the sound, it would be a win.

Thats info I was yet to confirm so thank you!

I was meaning other CV's for any other adjustments there might be.

CV8 to a value of 8 is the "reset to defaults" value, a few times and then the thing should eventually respond to address 3 and you should be able to re-programme as normal

quick check, because I have learned the hard way to not assume anything - you are doing this on a programming track and not on the main track? asking as not all decoders support "programming on the main"
