Backup Power

When a single fixture loses power, it would normally break the chain of digital communication. Using the backup power output of the next fixture in the chain, the communications part of the controller can be kept powered to keep relaying digital signals.

During this mode, all power-consuming components, including the backup power output and display,, are powered down.

Note that analog signals are always relayed, because these are simply direct connections from the IN plug to the OUT plugs.
