Running Backups

The data can be backup by running the following script periodically. The data can be backed up to the remote RAL webdav server or a local USB exteranl drive.


  1. See Trigger_Distribution_fanout_cables.pdf for how to connect USBDAQ to the Trigger Distribution Board. You willo need to connect up the 7-way IDc cable to teh 6-way socket on the Trigger Board and the 4-way + 1-way sockets on the USBDAQ (don't ask, see the diagram below).
  2. Start an xterm/terminal session 

    Make sure trigger board is powered up and USB cable connected to computer
  3. Load FrontPanel in FrontPanel directory. The Front Panel loads as pop up.

    Code Block
    > cd FrontPanel
    > ./FrontPanel.bin &
  4.    Download  configuration firmware by clicking on left icon on Front Panel (Arrow over single file). This will be greyed out if you have not plugged in the USB cable.
    1.   Open file testbeam.bit      [caliceon directory]
    2.    [N.B Do not open old firmware misleadingly titled testbeam_new.bit]
    3. Check FPGA is complete at the bottom of Front Panel window ("FPGA configuration complete").

  5. Load Front Panel profile by clicking right icon on Front Panel. (Arrow over two files)
    1. Open file testbeam.xfp      [caliceon directory]
    2. The old panel will display some lines and a new panel will pop up
  6. Select positions the trigger should act on by making the corresponding mask Busy.
    1. The USBDAQS are connected to the trigger board by coloured IDC cables. They plug into the trigger board into sockets numbererd 1 to 8.
    2. [Busy 1, Not Busy 0]. There are two 'Busy' lines on the Front Panel; the top represents the masks (1=allowed,0=blocked), the bottom the sensors.
    3. Numbers 8-1 at the bottom of the window control the masks.
    4.  Select the masks for the connected USBDAQS. For the 3 sensor mode shown below they would be 1, 2, 3.
    5. Line 2 is reported to be dodgy and should be avoided.
    6. In the 4-port dip switch labelled "MODE", the two centre dip switches (nos. 1 and 2) should be in the down position and the others in the up position. The FrontPanel window will show the "Trig Mode" as green for numbers 1 and 2.
    7. The counter can be set by clicking on "Count". To clear count click "CLR CN" and click again to restart.

  7. Start the data acquisition software in Tests/src tab.
