Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Try doing the setup for the remote device that the 200 was connecting to, in the garage, as if you were setting up the system for the first time, with the original instructions.
The configuration on each device or on either device if not on both, may have been lost, or changed spontaneously to non-working values. So setting up from scratch as if new from the store, would help with that sort of problem.
After that... it might depend upon several factors, as to what to do next. What's the age of each adapter? Was there a lightning storm or thunderstorm nearby at the time they seem to have failed to work?
