Reply to "DCS Acting Wierd"

My layout is also wired with a very large common ground system and does not use the “star” wiring system and I also have no problems. The entire layout is 25 by 40. The are many isolated blocks, each with its own power feed running back to a power strip near the TIUs. The star system was recommended by MTH because alot of people were using a common ground with only one or two power connections and one or two ground connections with only one block on a medium to large layout, thus they saw signal loss problems. If you have isolated block of 20 to 30 feet with one power drop and  ground drops for each block,  you are just fine. Not sure how big the OP layout is and how it is blocked. The “star” system tends to improve the signal but requires isolated blocks also. MTH says the power feed and the ground feed should be the same length for best results, mine probably aren’t but I get good results. MTH definition of “star” wiring is a paired wire with one carrying positive and the other carrying ground. You and I are calling “star” wiring for only the positive feeds.
