Re: Resistor for block detection, best size?

You will see that the block detection (i.e. when current is drawn) appears slightly before the Railcom ID is displayed. This is because it is faster being almost the instant a loco enter the block. The Railcom ID is then obtained from the loco and sent via Loconet to the command station. It is a sequential process and will always be sequential. ? The current is drawn by the decoder, even if the loco is stationary, and without a decoder you cannot get a Railcom ID. ? ?

? FYI Railcom has nothing to do with occupancy, it is simply reporting the details from the decoder. The actual occupation comes from the current draw by the locomotive (or wagon).
? So let me ask a dumb question, as I’ve only set up sample blocks with DR5088RC and have seen the RC ids show up in my blocks but don’t actually detect any current. Why do I care about he occupancy current? ?If the RC id is showing its obviously in the block. ?It won’t show an id for the block if it’s not in the block. ?I get the technical difference, but functionally, it is detecting occupancy. ?Because, as I said, the existence of the id shows its occupying the block. My question is one of understanding as my current “layout” is a simple oval to test my software as I get set back up in our new home over time and start a bigger and more complicated test layout and then a “real layout” to keep me going until I die :)
