Re: [sudo-discuss] pair programming station and UPSs

by "jake's co-working station" robb means "the pair-programming station" which is a desk on wheels with two monitors, two keyboards, and two computers arranged symmetrically so that two people can use the same computer. https://sudoroom.org/wiki/ there are three UPS at the pair programming station. One is the one that the station is plugged into, which does not have a USB port, just the weird DE9F socket that may have this pinout: http://www.diger-mobile.narod.ru/pic/apc_conn.gif or this: http://www.junradio.com/mid/UPS/image003.gif there's another large UPS on the floor which got rained on and stopped working, which is unfortunate because it has USB and i actually had it working on a rooftop system, protecting that system from unexpected power failures (it would safely shut down when power went out, and turned back on when power returned) but maybe it could be fixed and the third UPS is a weird 12v thing like this: https://www.amazon.com/Belkin-Battery-Backup-Supply-BU3DC000/dp/B004RRX1CG http://cache-www.belkin.com/support/dl/p75319-b-bu3dc000-12v.pdf it doesn't have any alarm outputs (unless you count the LEDs) but since it serves the DC output directly, we can monitor battery voltage the same way it's done at the front door computer - that is, it's 13.7VDC when AC is present but it will go down if the power fails. -jake On Thu, 27 Oct 2016, robb wrote: there's a working 12v ups by jake's co-working station > > is ccl onboard with locking the door? > > On Thu, Oct 27, 2016 at 3:43 AM, Marc Juul <juul(a)labitat.dk> wrote: > >> We definitely want a door.
