Help! I have a Gaugemaster DCC30 Accessory Decoder. I'm told it's a "rebadged" MRC Prodigy module. If you send basic commands via Decoder Pro and a Sprog II, it works. It also works with a Lenz DCC controller. It does not work with DCC++ on an Arduino Uno using the DCC++ Controller. It does not work with a z21 Start system. I know the z21 systems have a glitch with addresses but I've done the recommended upgrade to the firmware and ticked the requisite box for the "fix" and successfully saved it to the z21 start. I have a couple of simple layouts configured on an iPad using the Z21 App. Everything seems to work "on screen" but the decoder does not switch anything and it's indicator LED does not light. Anyone have any experience with the DCC30, please?
