Need a tip on Consists with diff. decoders.
Posted by Gerome on Wednesday, March 12, 2008 1:10 AM

How difficult is it to get the decoders from two different manufacturers to run smoothly together? I hoped to use a Soundtraxx LC and a NCE D13SR together in a consist

Is is just a case of observation and trial and error with the CVs for acceleration and deceleration, V start etc.?

Many decoder instructions mention having the loco just begin crawling at Speed Step 1.  I use a Digitrax Zephyr.  Is Speed Step 1 the Position 1 throttle setting on any given controller, or is it someting more sophisticated?  I suppose if I get the various decoders just starting at the same setting, accelerating and decelerating at the same rate I am getting close to my answer?

Would be grateful for any tips, links to advice etc.

Yep, trial and error.

But with DecoderPro, it's very easy to speed match locos, even when using different decoders.

I have a Digitrax DCC system, but use a mix of NEC and Digitrax decoders.  Sometimes you need to speed match locomotives with the same decoder if you are going to run them in a consist.

1.  Purchase an electronic system that measure the scale speed of the locomotive.  There are a few available.

2.  Use a throttle that allows you to read specific speed steps or %age of throttle.

Thank you for the specific info, David.

A couple of questions: 

How expensive are these electronic systems in Point 1 above?

I take it that a Digitrax Zephyr is not sophisticated enough to complete Point 2 above as there is no way of reckoning percentage of speed with the simple throttle pointer?

(anyway, my Zephyr just packed it in/went haywire.  I'll see how they do fixing it under warranty.  I may have to switch to another throttle if I am not satisfied.)
