The Caladium telescope control and DAQ is handled by the National Instrument (NI) 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 ESADUTDAQ1 server node (replacing ESA-USER02) 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 beam trigger. The SWH-B061-NW01 network switch in the middle of the ESA hall support the ESA-RESTRICTED local network 172.27.104.* (port 25-48) where both the NI crate and ESADUTDAQ1 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 172.27.100.* (port 1-24) on the same switch, but can also see the local ESA-RESTRICTED subnet. The connection from the NI crate and ESADUTDAQ1 to the switch are routed through the Belgen patch panel inside the tunnel near the optical table.        

The current version of EUDAQ on the DESY/CERN telescopes is 1.7 so we have updated the version at SLAC in May 2018.  v1.5 is still on the machine and can be run instead of v1.7, but you need to physically change the USB cable going from the TLU to the TLUproducer computer to instead connect to the NI crate.   (-BPN 6/1/2018)

Telescope operation (EUDAQ v1.7)

0. In ESA:

- Start chiller: 18 Celsius
- Switch on power supply: 8V constant --> check 2.0 A
- Switch on NI crate and TLU 
  
1. Start sensors
  
- Remote access to NI crate: 
-- Open Terminal 
-- source access_NI_crate.sh
-- Login: telescope PWD: telescope+
  
- Start MI26.exe (upper icon on the NI crate Desktop)
-- Open .mcf threshold file, typically 6 (CALADIUM config files are in C:\opt\mimosas\config_files)
-- Press "Reset" --> 2.0 Amps
-- Press "All" --> 2.8 Amps
-- Press "Read" --> 2.8 Amps
-- Press "Start" --> check 3.6 Amps
  
2. Open Labview FPGA interface on NI crate, if not already open
- Double click MimosaDAQ (second upper icon on the Desktop)
  
3. Start EUDAQ on AR-EUDAQ:
  
- Open a second Terminal 
- cd /opt/install/eudaq/eudaq-1.7 (need to make a shortcut -BPN 6/1/2018)

- ./STARTRUN
- wait approx. 20 sec. until all Connections ping (unitialized)
  
4. Open TLUproducer on TLUproducer computer.  N.B. this is currently the YARR computer but we need to change this when the YARR folks are not at SLAC! (-BPN 6/1/2018)

- (if not done already: ssh -Y pixel@172.27.104.52; there is an ssh key so no password should be needed. Just in case, you can ask any LBNL person)

- cd /local/pixel/eudaq/eudaq-1.7/bin

- ./TLUProducer.exe -r 172.27.100.8:44000

--> check in eudaq Run Control, that Produce TLU is connected
  
5. Start DUT data producer(s) if not running telescope by itself. 
   For standard RCE based DUT readout, this should be just starting rceOfflineProducer on esadutdaq1.    

6. Configure EUDAQ in eudaq Run Control
- select init file (can use the example) and init; then select Config file  (Caladium only exercise config: no-beam: ni_autotrig; beam: ni_coins)  
- Press Config
- wait till all Connections are green (OK)
  
7. Start Run
- Press Start (wait till all green)
--> check, that Trigger and Event Built numbers are increasing
--> check OnlineMonitor, and reset (upper left x-button)
  
8. Stop
- Re-configure (5.) and Re-Run (6.)
OR
- Terminate and press "Reset" in MI26.exe at NI crate to stop sensors --> check 2.0 Amps
