Hi John,
No, we don't have a UPS in place just yet. The single scanner feed up right now is just the beginning. Will be throwing one of those on later. Possibly would have prevented the issue that arose yesterday. The ISP-supplied router was doling out an IP, but the connectivity was not there. We had the final LAN configuration that finally worked set up the exact same way several times but there was no connectivity. Dave graciously helped us in the final stages of angst, after we could get nothing, and suddenly the Pi was showing up for him. So it's back up for now. There will be a small interruption or two as the site gets straightened up today.
...good call on the UPS.
