BASIC PROGRAMMING NOTES
DCC & SOUND EQUIPPED MODELS
Customizing the programming in your DCC & Sound Equipped model
is yet another way to get more enjoyment from your investment. With
a few basic guidelines, customizing can be easily done. You may also
wish to have the manual for your DCC system handy as well in case a
refresher is necessary.
It is recommended that you use Paged Mode programming to adjust
CV settings on your DCC system’s programming track. While this is
the recommended mode, Direct Mode may also be used and in many
cases, except a decoder reset, some adjustments can be made with
Programming on the Main (i.e. address programming, master volume
change, horn or bell choice, etc). An auxilliary programming track
booster is not necessary to program an ESU decoder and can interfere
with programming in some instances. DCC CVs cannot be adjusted
if you are operating your DCC & Sound Equipped model on a DC
powered track.
If you will operate your AC4400 on DCC, it is recommended that you
download, read and understand the appropriate Loksound decoder
manual for the decoder in use in your model. The V5 manual is
document # 51989 on the ESU download webpage at www.LokSound.
com and is correct for all DCC & Sound Equipped models produced
after January 2019.
DIGITRAX CV PROGRAMMING FOR CVs OVER 255
Some older Digitrax DCC systems do not allow programming of CVs
above 255. In order to make full programming possible, we have
implemented an assistance tool. This helps to write the number of
the CVs desired temporarily into two assisting CVs (so-called address
registers), since the usual CVs cannot be reached. Afterwards, the value
of the CV desired will be programmed into another assisting CV (value
register). When the value register is written, the content will be copied
to the actual desired position and the assisting CV will be set back.
Consequently, 3 CVs have to be programmed to write one CV. These
three CVs are described in the following text:
CV96 - Name Offset CV - Saves the CV number that should be
actually programmed in hundreds. Value Range: 0 to 9.
CV97 - Address CV - Saves the CV number that should be actually
programmed in units of tens. Value Range: 0 to 99.
CV99 - Value CV - Saves the value of the CV that should be actually
programmed. Value Range: 0 to 255.
Example: Need to program CV317 to value of 120.
Program the value of the CV number in hundreds into CV96.
In this example: CV96 = 3
Program the value of the CV number in tens and ones into CV97.
In this example: CV97 = 17
Program the desired value of the target CV into CV99.
In this example: CV99 = 120
