The Caladium telescope control and DAQ is handled by the National Instrument crate which collects data via the TLU with data producers from the telescope itself and the DUT. The DUT readout is upgraded to a simpler arrangement with just the HSIO-II controlled by the ESA-USER02 server node via a direct private ethernet link. Due to the very short ESTB bunches, there is no need for additional triggers within the bunch and the DAQ is simply driven by the bunch crossing trigger. The SWH-B061-NW01 network switch in the middle of the ESA hall support the ESA-RESTRICTED local network 127.27.104.* (port 25+) where both the NI crate and ESA-USR02 reside on. The EUDAQ console PC AR-EUDAQ in the ESA Control Room and several other nodes e.g. AR-ESAUX2 are connected to the ESATESTFAC public subnet 127.27.100.* (port 1-24) on the same switch, but can also see the local subnet 127.27.104.*. The connection from the NI crate and ESA_USER02 to the switch are routed through a the Belgen patch panel inside the tunnel near the optical table.

The beam dump monitors, Lead Glass (LGdump) dump, and Front/Read dumps are a key monitoring tool to give direct look at the beam intensity. ESTB GUI "Scope ESA" panels is particulary useful as a standard monitor for instantaneous beam status as scope pulses. "ADC Chanls"/"Histograms" panel displays the instantaneous values and distributions of energy measurements of various dumps. "HV SY403" can be used to adjust HV values for different intensity measurements.

Control (to be updated for Apr/2016 - a new strip is dedicated to Caladium+DUT DAQ rack)
The "AC Power 7" sub panel accessible from the main panel above contains the individual socket controls for the power strip sitting on the large tall bench at the entrance to the test beam tunnel next to the telescope. Most ATLAS pixel DUT setup powering are using the sockets on this strip. Clicking on individual channel channel's "Reboot" button will recycle power on that channel. Some channels may automatically flip the state to green after a brief moment, others may need deliberate push on the state button to reenable. Some relevant outlet numbers on this AC Power 7" strip (IP: sioc-esa-acsw7) for the ATLAS pixel FE-I3 test setup (Jan/2016):
