Zero 88 Demux 48

[medina]

Hi All,

During yesterdays Panto we started to get a few channels flickering, we put this down to our old dimmers so repatched a few channels and all was good. 20 minutes in a call from the LX op says that "its gone weird". we look at the desk, all seems to be working but the states look wrong. I went to check the dimmers and the demux to see if any error lights are on and discover that the address on the demux is now reading 23 instead of 7. I change it back during a cue. 10 mins later it goes again, I check and this time it says 12 and whilst waiting to reset, it changes to 27 on its own. Has anybody else ever known this to happen? or any idea what could cause such an event?

I am confused!

Thanks

Check the internal battery, this is often the cause of strange happenings on a Demux 48.
