KB696 Decimal and Hexadecimal Notation

As technology has advanced so have Digitrax throttles.  In the early days, it was not possible for the throttles to display decimal notation so hexadecimal was used.  The downside to hex notation is that you need to use a conversion table or a formula to determine the hex value to use for CV programming.  As better components and CPUs became available, we were able to move to the more user friendly decimal notation that you see in today's Digitrax throttles.  The move to decimal notation made DCC much easier to understand for everyone.  All current Digitrax throttles use only decimal notation for ...

KB670 Configuration Variables and Factory Default Values Used By Digitrax Decoders

This is a list of all configuration variables (CVs) and their factory default values in decimal and hexadecimal notation used by Digitrax mobile decoders.  Simpler decoders access only a few of these CVs, while advanced decoders access many, if not all, of these CVs.  

KB237 CV29 - Configuration Register - The Addition Method

CV29 sets the characteristics for 5 different decoder behaviors. The table below shows each characteristic and its value if it is on or off. Notice that if the switch is off the value is zero. Click here to go to the automated CV29 value calculatorTo determine the value to program for your decoder just go down the list and add up the numbers for all the switches you want to set as ON. If you need to convert the decimal valueCV29 Examples of CV Values: The factory default value for CV29 is 06. Switch # Characteristic if OFF Value if ...

KB182 Speed Value Percentages - Decimal and Hexadecimal

Since 255 can't be divided evenly, the some of the numbers in the range 0 - 100% have been rounded.

KB557 CV29 - Configuration Register Look Up Table Method

CV29 is called the configuration register. It controls the following decoder characteristics: 1.  Whether the decoder uses 14 speed steps, 28/128 speed steps or loadable speed tables.  This affects how smoothly the loco will move and how it responds to throttle controls.2.  Whether the decoder automatically converts to analog mode when no DCC signal is present.  This allows the decoder to operate on a DC layout even though it is DCC equipped.3.  Defines the normal direction of travel for the locomotive. Normal Direction of Travel or NDOT can be changed when the motor connections of decoder have not been connected so that the locomotive runs ...
