How to I find the correct serial number for my SDR Play RSP1? There is a label on the bottom of my unit with its supposed serial number. But I am trying to use it with DSDPlus Fastlane, and the FMPP.cfg file expects a 10 digit serial number, which mine isn't. Mine has "RSP", hashtags (#) and decimal points mixed in, which FMPP.cfg doesn't accept.
