10.0 Decoder Utility CVs

The decoder utility CV group handles decoder reset to factory default CV val-

ues, decoder lock for programming when multiple decoders are present in a

locomotive and decoder ID information.

10.1 Factory Reset CV: 08

CV08 is the factory reset CV for all FX

decoders.

For Series 3, 4, 5, & 6 decoders, reset all CV values to their factory default,

program CV08 to a value of 008. This will also cause sound projects to revert

to the factory installed project.

For Series 3, 4, & 5 decoders, reset all CV values except for 28 step speed

tables to their factory values set CV08 to a value of 009. For Series 6 sound

decoders, programming CV08 to 009 will also preserve the current sound proj-

ect selected by CV60.

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.

10.2 Decoder Lock CV15, CV16 & CV54

Decoder Lock lets you use more than one decoder in a locomotive and be able

to program their CVs separately. Since all decoders with the same address will

accept programming commands directed to that address, decoder lock avoids

the inconvenience of uninstalling one or more of the decoders in order to pro-

gram CVs in just one of the decoders installed in the loco. For example, if you

use a mobile decoder and a sound decoder together in your locomotive, you

can use the same mobile decoder address during operation and when program-

ming you can unlock only the one you want to program.

Note: If you are installing only one decoder in a locomotive, there is no

need to modify the default values of zero in CV15 and CV16.

Decoder Lock is a manufacturer specific CV. The instructions provided here

are for Digitrax decoders. If you are using decoders from another manufactur-

er, please consult your decoder’s instructions for how this feature works with

the decoder you have installed.

CV16 sets the ID number of each decoder installed in the locomotive.

CV16 can be programmed to a value from 0 to 7 inclusive. This value iden-

tifies a single decoder. A unique value must be assigned to each decoder

installed in a particular locomotive so that it can be selectively unlocked for

programming later.
