DS74 Weirdness

Model Railroader Electronics and DCC

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?

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.
