The series II Barco projectors have a short "jumper cable" with a male and female power connector joining the 208/240 line power to the projector electronics, this jumper sticks out the back of the projector. If you want to have a UPS on the electronics you remove this jumper and connect the electronics power input to a UPS. I don't understand your question. Barco doesn't provide a UPS. The projector does not require a UPS. If you add a UPS and configure your projector and (ups protected) server properly it's possible to recover from a short duration power loss very quickly. Without the projector UPS you will have to wait for the projector to reboot before restarting a show, about 2 minutes I think. A UPS is, I think, an absolute requirement for your server. A server power failure at the wrong time can scramble the RAID and rebuilding it takes hours. You may be unlucky enough to scramble the SSD system drive and that may take days to fix. The projector doesn't get screwed up by a sudden power loss, in my experience anyway. Every time you switch the Barco off you cause a sudden power loss. If you have a lot of short duration power losses where you are, a projector UPS may be worthwhile. If you have reliable power and dropouts are rare then maybe forget about it. You also have to look at how your server reacts to power dropouts. Doremi can work with APC UPS units to pause the server when line power is lost, but I don't think they will restart into "play" when power comes back on. You can set up a UPS protected projector to start the lamp as soon as line power comes back on, but this is not a great plan if the server is paused. If the server has stayed in play during the dropout, patrons will be miffed about missing more than a few seconds of the program. Plus when the emergency lights come on, in my experience, everyone goes to the lobby. That will take long enough to sort out that waiting for the projector to reboot is not your big problem.
