Canada. Did you find the problem or still fighting it? Hopefully you found it!

Some dcss and lwcss comm timeouts and errors are normal on 411,311 and Gem controllers with imotion operators. if not equipped with the buffer board. They don't require the buffer board unless the door board it upgrade to the new board. Trust me you will know right off the bat it needs it. The comm errors will just start counting up and it probably won't open or close the doors
