KB460 DT402 & DT400 - Operations Mode Programming

Ops Mode programming, also known as "Programming on the Main" lets you change the configuration of an individual decoder while the locomotive is on your railroad without having to move it to the programming track.Operations mode programming lets you program CVs in DCC locomotives equipped with Ops mode capable decoders while they are on the mainline. A typical use for Ops mode programming would be to change the acceleration rate (CV03) or the deceleration rate (CV04) of your locomotives to simulate the weight and braking capability of the train to compensate for changing the number of cars or power units on a ...

KB845 Zephyr - Operations Mode Programming

Programming On The Mainline: Operations Mode ProgrammingOperations Mode Programming [Ops Mode] lets you program CVs in DCC locomotives equipped with Extended Packet Format decoders while they are on the mainline.  This is handy for situations where you want to make an adjustment to a specific locomotive while it is in service.  There are also situations where mobile decoders from other manufacturers can only be programmed in this manner. A typical use for Ops mode programming would be to change the acceleration rate (CV03) or the deceleration rate (CV04) of your locomotives to simulate the weight and braking capability of the ...

KB878 14, 28 or 128 Speed Steps-Why?

This article was originally posted on this site in 2006, but the source material dates back much further than that, probably back to the early 1990's, when DCC was an emerging control system. The article discusses non-sound mobile decoder programming operations. Many of the issues discussed in this article are less relevant when using recently produced decoders, but this text still does cover some questions which may be raised when you are using mobile decoders which were manufactured by other companies. These decoders will operate in the Digitrax environment, but you may need to make some adjustments.The earliest Digitrax mobile ...

KB720 Trouble reading CV values with SFX064D

If you have trouble reading back CV's on the programming track, this may be due to insufficient current draw on the SFX064D function leads. You can always just re-program the CV value into a CV to get the desired results, even though reading CVs does not work. OPs mode is recommended for programming all CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses). If a second DCC decoder is present that is not Sound FX compatible then correct readback of CV data is not possible, since the NMRA CV readback was not designed for multiple decoder readback.

KB475 DT400 Series Throttle - Operations Mode Read-Write

  Q:  How can I write and read the Configuration Variables of Mobile Decoder on the mainline using the DT40x Throttle? A:  Operations Mode Programming, also known as Ops Mode, lets you program a locomotive decoder's CVs while it is on the main line. With the addition of transponding in Ops Mode, you can write and read back CVs in DCC locomotives equipped with most modern decoders while they are on the mainline. Some older decoders before Extended Packet Format was used are not able to do this.For example: A typical use for Ops mode programming would be to adjust an engines ...

KB476 Operations Mode Read Back - Minimum Transponding Hardware Configuration

Operations mode (OPs mode) programming allows you to program decoders on the layout instead of having to move them to a separate programming track.  This is a write only programming method.  If you want to be able to read back the values written to a particular decoder using Ops Mode programming, you will need to install transponding on the layout.  If transponding is not active on the layout, you must use an isolated programming track for reading back CV values.The extent of the area with OPs Mode readback available depends on how muchof the layout is instrumented for transponding. The ...
