This article was last updated on Jan. 10, 2012, 9:41 a.m. | Print Article | Leave Feedback

CV08 is the factory reset CV for all FX3 decoders and also the Manufacturer ID CV for all decoders.

This procedure is performed on a programming track.

To reset all CV values to their factory default, program CV08 to a value of 008/x08 while the locomotive is on the programming track.

To reset all CV values except for 28 step speed tables to their factory values set CV08 to a value of 009/x09.

Earlier Digitrax decoders must be reset manually, CV by CV.

This procedure may or may not work with other manufacturer's decoders.

When you "read" the value of CV08, Digitrax decoders report back "129".

This number is unique to Digitrax, and other manufacturer's decoders report back other values.

Note
: Performing a factory reset will not affect the manufacturer ID and will reset the decoder's address to the factory default of 03, a 2 digit address.
