Yes it does work. For me it happened instantly with no config required.
A few things to check:
- The green light on the UR93 should flash every second. If you make a change in the DT602D throttle (eg F1) then the green light will flash at a different rate for a moment.
- The YD7001 LocoNET RX light should flicker whenever it sees data - eg pressing a function key).
- I have the DT602DE throttle as it uses the European frequencies and not the USA ones. I assume you have checked the use of the UR93 with a Digitrax control unit.
