![]() ![]() It can read the entire decoder's CVs very quickly. Then "Is Bit 2 set?" Instead of making up to 256 inquires to determine the value of a CV, it can do it with eight. Faster Readback of CVs Instead of asking "Is it 1?, Is it 2?", Direct Mode takes a different approach. The NMRA would like to replace Paged Mode programming with Direct Mode. Direct Mode The popularity of Direct Mode is increasing all the time. Every CV will be tested sequentially in this manner. Reading the complete CV set of a decoder will take a long time. If the response is negative, the number is incremented by one, and the process repeats until a positive response is received from the decoder. To read a CV, a number is sent to the decoder. It is very slow when reading back the CVs. Paged Mode Paged Mode introduced the term "CV" (Configuration Variable). ![]() ![]() ![]() Use typically Direct Byte or Paged Your Locomotive Roster Roster Photo OPS mode programming requires accessing the locomotive /mobile decoder via the decoder’s ADDRESS.ġ7 Some recommendations Test Track – setup a loop of track 22” minimum radius if you do not have a layout higher if needed Separate / Isolated Programming Track – use this section of track for PAGE mode and DIRECT mode programming Locomotive Roster Database ? USE JMRI DecoderPro! – DecoderPro’s database makes a great roster database (we’ll show how) Purchase a decoder tester – test and configure your decoder before you install it in your locomotive or rolling stock Join DCC Yahoo Groups – lots of help and documents on DCC and Programming This is address- independent OPS Mode Programming: programming on the MAIN LINE track no feedback is available to the programming software / hardware. This is done on a isolated programming track. To access the locomotive /mobile decoder, you enter the address in the DCC throttle / system Service Mode Programming: programming with feedback / acknowledgement from the decoder. JMRI is an open source program for model railroad hobbyists JMRI is a Program Suite, consisting of: DecoderPro® - A better tool for programming decoders, simplifying the job of configuring DCC decoders from your computer PanelPro™ - Design and Operate CRT based CTC control panels that reflect the real-time state of your railroad and let you control it DispatcherPro - A system for Dispatching, grouping your Roster and Throttles OperationsPro™ - Build Trains from your Roster and print Train Manifests that detail the work your train crews will perform AudioPro - A set of tools for using Audio with JMRIĪ computer running Windows, or Linux (various types are supported) Java A DCC System or a SPROG ( A computer interface for your DCC systemĬV – Configuration Variable: DCC Decoder settings for motor control, lighting effects, consisting controls and sound effects (a cv is something you can adjust – a setting) Address: the DCC decoder’s ID number.
