I have four systems and they all have froze up at different times in the last 2 months.
Is there anything we can do so they don't freeze up . The last time they froze even doing an IRC to take the one off line that was causing problems it said I had only the one left on line., and that was the one I did the IRC on. I would go to another system and do an IRC and it would say that one was the only communicating.
Any suggestions?

Battery Backup UPS!

Uniwell kit is awful with power. I have seen so many Uniwell systems have problems with dropping comms but when you add a battery backup UPS onto each bit of equipment inc printers 90% of all problems go away. Fridges turning on and off, extension leads etc all cause problems and the only thing that stops it is this.

Its even worce on the newer Uniwell kit that can use the table plan.
