Digitrax UT4 R Throttle
Herman asks readers:
“I am using a Digitrax UT4 R throttle on a DCC power railroad, can you control a switch machine when having an opt session?”
Include your comments below.















If the switch machine is wired to a stationary decoder you should be able to control it with your UT4R throttle. I’m not familiar with that particular throttle, but the Digitrax book that comes with it (download it from the Digitrax site if you don’t have it) will tell you how to go about doing it.
