Started removing serial data leads from each switch until the DZ-2001 LED went out, I replaced that switch machine. Reprogrammed the new switch machine and we were back in business.
John,
This is my biggest concern. You stated you first Disconnected all the serial data feeds, then after re-powering them, you disconnected them again. Did you re-connect them first before disconnecting them again (one at a time?)
I have a feeling I will be doing this too.
Thanks.
