DCC function mapping
Posted by The Crown Valley Railroad on Tuesday, February 18, 2014 2:04 AM

My MRC Prodigy Express handset does not have a shift key. How do I access functions 16-28 on my sound decoders? I've heard about function mapping but don't know how it works. Any help would be appreciated...

Function mapping is when you can reassign throttle buttons to do things differently than what they were set up for. As an example: F0 usually turns the light on and off. You can remap it so the light turns on and off using F5 instead. doing it manually is a complicated process (I think). I have never done it manually. I always use JMRI's Decoder Pro and a computer, which is hooked to my DCC system.

Since you have MRC, you can't use JMRI because MRC won't give out the specs to their system. Because of this, most serious modelers don't buy MRC DCC systems. MRC does have their own computer program, and it MAY do function mapping, but I don't know. Contact MRC to find out.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

Function mapping is a process within the decoder. You will need to know what type of decoder is in your engine and download the manual for it. The manual will have a section for function re-mapping. Follow the parameters in the manual and change the appropriate CV's using your program track just like any other changes.

If you are referring to a soundtraxx or MRC sound decoder, it's not too bad of a job to absorb the information. If you have a Loksound decoder, you're in for a heap of learning to do it manually.

 Just remember that it does not magically give you more functions - if you remap what's on F25 to be on F5, then what's currently on F5 has to be disable or moved to a different function. You can have more than one function activate with the same key, but for sounds that's generally not what you want.

Even though you have an MRC system, if you're satisfied with it, there is no need to upgrade, unless you're going for the full acsess another system can give you.

What you can do is;

1. Download and install on your computer JMRI.

2. Buy a Digitrax Pr3, a Locobuffer, or a SPROG. If you get a Pr3, get a wallwart transformer of 12-15V 1A capacity.

3. Buy a PTB-100, and get another wall wart to power it.

4. Load the Pr3 software. Plug it into your computer. Set up JMRI.

Start the easiest programming you've ever done!.

Hi,

I’m with Cary, if you have a small layout stick with your Pro and get a Sprog, a length of flexi and a couple out croc clips.

I use Gaugemaster (MRC) Prod 2□ x 4 on the layout which is a few miles from home, so I do most of my programming at home at me desk; any matching is done on an isolated branch at the club which can get busy on running nights.

Hope this helps. 

Oh ye if you get into retro fitting decoders I’d get hold of an NEC Decoder Checker and program on that, then mount them on the locos.

Be in touch.

Pick.
