The Stairwell displays are run from the Ubuntu machine, auscope-screens at 131.217.62.142. User auscope, password the usual.
Please power-down the stairwell monitors using the switches under the main desk labelled Screen 1, Screen 2, … when finishing an experiment or after hours to save power. Please power them up at 8-9am weekdays if you are in the control room. The display computers (Raspberry Pi's) are shutdown automatically at 4pm each day.
The switch labeled Screen 4 also powers the Raspberry Pi's.
There are instructions for controlling the displays on the Desktop of auscope-screens. You can ssh or vnc the Raspberry Pi's after first logging into the auscope-screens machine. The Pi's are on a subnet, quarantined from the uni network, routed through auscope-screens. The Pi's can display video, pdf's, slide shows in pdf format, and can access web pages and resources.
Instructions
Turn off/on power switches for screens under desk in Auscope room (north west corner).
[1][2]

The four pi (and network switch) are connected to switch [4] power.
A cron job on auscope-screens will shut the pi down at 3:55 pm daily (shutdownpi.sh).
If communication is lost, power cycle with power switch [4] under desk.
On boot the pi should start looping through randomly selected movies.
(play.sh called in /etc/rc.local on pi)
You can ssh each pi[1-4], user is pi, e.g.
ssh pi@pi2
SSH keys are all in place. Passwords are all the usual.
You can also vnc each pi[1-4], e.g.
vncviewer pi3
For remote access first ssh into auscope@131.217.62.142, then ssh the pi
