KB900 DZ121 - Short Address Programming Notes

Short Address Programming Note When programming the short address (CV01) in your DZ121, the decoder will automatically set CV19 to 0, CV29 to 0, CV 55 to 80, CV56 to 30 & CV57 to 0. This is done to insure compatibility with DCC systems that only recognize short addressing (2 digit mode). When using long addressing (4 digit addressing) these CV's are not affected.After changing the short address (CV01), you will probably want to change CV29 to 06 or another appropriate value based on your operations. You can do this on the programming track or, if you forget, you can ...

KB932 CV29 - Configuration Register - Overview

CV29 is also called the Configuration Register.  It is a special CV that handles several different aspects of locomotive behavior.Characteristics Controlled by CV29:1.     Speed Step Control:  Advanced Mode (28/128 speed steps) or Standard Mode (14 speed steps).2.     Speed Tables: On or Off3.     Analog mode conversion: On or Off4.     Normal Direction of Travel (NDOT)5.     2 or 4 Digit Address selectionDetermining CV Value To Program Into CV29The numerical value value you will program into CV29 will affect many important decoder characteristics.  Each of these characteristics is controlled by a "software switch." This switch is either on or off depending on the CV ...

KB236 CV29 - 2-digit or 4-digit Addressing

  CV29 is assigned a single value which chooses a combination of specific effects: 1. Speed step control. 2. Speed table On or Off. 3. Analog mode conversion On or Off. 4. Normal Direction of Travel (NDOT). 5. 2 digit addressing or 4 digit addressing. 2-digit or 4-digit Addressing The decoder's address is the identification number programmed into specific decoder that lets that decoder recognize commands sent to it by the command station. Once you program the decoder's address, it will be remembered in the decoder until you re-program it. All Digitrax current production decoders can be set up with ...

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 ...
