You question hasn't gotten much traction. I'm pretty sure Group.io has a digitrax group that might be able to help.
Not a digitrax guy but I used to live in an area where power surges and outages were routine. I don't know if you devices are rebootable or reset to default, but that is my first thought.

Hoping to get help from the Forum before trying to escalate this to Digitrax.
I have 3 DS74s installed on the layout, controlling Tortoise machines. These are configured to switch #s 101-104, 105-108, and 109-112 respectively. All have been operating without any issues for a couple of months. Yesterday I come down to the layout and the lights on the 2nd and 3rd DS74s are blinking quickly in alterternate (red-green) fashion, and the two controllers no longer operate the machines - it does not appear that they are being recognized by the loconet, or are accessable for programming or reset via the main control (I'm using a DT400 throttle). The first DS74 is still operating just fine.
Any ideas out there as to what the problem might be and how to fix?
