I wanted to know because with rereading the instructional book that came with the TIU that said the DCS would operate better in a certain pattern. I had used a bus line for a long time. Does anyone out, knowing if what digital power is very much different? Please respond. I used to communicate with Jim Barrett of OGR, on any information, about DCS system. is another person out there that can talk about DCS? I'd be glad to speak with you.
