Thank you both for your quick response. Ben, the mirror mode you described is EXACTLY what I had in mind. This is essentially the layout of the Gillig Coach, (SLK processor, power supply, scanner, and I/O’s) as manufactured in 1999 up in Hayward, CA . I am proposing (WAS proposing) a 16ga twisted pair shielded cable running the spine of the coach and meeting up with a MicroLogix controller and other paraphernalia like fuse blocks, relays, and other harnessing. My nephew put me onto the Opto-22 system and he recommended the CAT 5 approach too. Eliminating the fuse and relay middleman seems more efficient so now I am just reconfiguring my brain as to what is needed in your system
“Do you ever cruise through Southern California in one of those coaches?”
No, but the VL-100 and the Clipper are well represented in that part of the world. I am East Coast bound unfortunately (not that I won’t ever get there) but we just had our bi-annual rally in Loudonville, OH (Flxible was in continuous operation there from 1913 thru 1996) http://youtu.be/4P-20l6-EdE. We will hold our bi-annual rally for the West Coast in July of next year, probably at Quartzite, AZ. As you can see the coaches are in various stages of restoration. The smooth fronted coaches are the Vl-100’s, Flxliners, Hi-Levels and the bug-eyed coaches are Clippers, Visa-Coaches and Starliners. The FLAT fronted coaches are the more modern ones called Model 870’s and METRO’s. Even an aficionado like me needs a scorecard to keep up with them.
Thank you for the invitation, information and the links. I have a lot to absorb here but I am motivated.
