Locking decoder

[geoffwbasig]

Apologies for troubling you again but I am finding that with my DP8/SC1 combination , every so often the decoder will "forget" its settings meaning I have to go back to the NCE Power Cab programming track, reset CV 38 to 15 and then reconfigure the DP8 with the required accessory addresses.   I believe that CVs 15 and 16 can generally be used to lock decoders but would these work with your decoder?

This is happening quite frequently and is a bit of a pain.

Hi Geoffwbasig

You may well have a faulty SC1. This should not happen, and the decoder lock feature will not help. The problem appears to relate to the decoder incorrectly reading the manufacturer ID in CV8 when powered up.

One thing to try if it happens again is to disconnect the k wire on the DP8 and perform a factory reset (write 8 to CV8) before reprogramming CV38 to 15.
