Original MRC Prodigy Question

[Dan Bowman]

I'm in the process of wiring up my layout for DCC.  I'll be using the original MRC Prodigy system.  I want to add extension plates (AD492) on a daisy chain.  There are several places I need to make longer runs than the supplied 12 ft. cables.  MRC says they don't recommend going "much" longer than 12 ft. if using custom cables.  I assume this is because of voltage drop on the longer cables.  Has anyone used a MRC Prodigy and installed extension plates on longer than 12 ft. cables?  If so what has been your experience?
