Inc Sound Module Decoder - Manual

www.digitrax.com- 29 -

Operations mode programming allows programming of decoders while the

locomotive is on the mainline without having to use the programming track.

The decoder address can be programmed with Ops mode programming with

Digitrax DT300 & DT4xx series throttles. Some DCC systems allow operation

mode programming only for CVs other than address.

Physical register mode is a very basic mode for programming decoders. With

“register mode” you can program CVs 01, 02, 03, 04 & 29 only. This is only

used with older decoders that require this method.

All of these programming modes may or may not be supported by your non-

Digitrax command station or programmer. For the specifics and mechanics of

programming with your system, please check your command station or pro-

grammer manual.

5.4 DCC Outputs: Programming & Layout Operation

The DB150 Command Station/Booster, has one DCC output that is used both

to run the trains and to program decoders. For this kind of command station,

you will have to shutdown layout operations to program in service mode.

The DCS100/DCS200 Command Station/Boosters and the DCS50/DCS51

Command Station/Booster/Throttle Combos have two DCC outputs. This

means that you can program in service mode and read back decoders without

having to shut down the layout. Both single and dual DCC output systems

require a service mode programming track unless you are using operations

mode programming on the main.

5.5 Reading & Writing CVs

The DB150 Command Station/Booster has a “write only programmer,” it will

program CVs to the values you choose. DB150 will not read back CVs and

their values programmed into your decoders.

The DCS100/DCS200 & DCS50/DCS51 Command Stations are “read/write

programmers,” they can program decoders and read back their CVs and values.

Another programming option is to use a PR3 Xtra programmer and your com-

puter to program and read back decoders. Other DCC compatible programmers

are able to program Digitrax decoders as well. Consult the manual for the sys-

tem you are using for complete programming instructions.

Digitrax FX

decoders have operations mode read back capabilities when used

on layouts instrumented for this feature.

Note: Some DCC systems use a low power setting for all decoder program-

ming. Digitrax recommends that you use low power programming for initial

decoder tests prior to installation in the locomotive. We do not feel that it is
