How do I .... ? (This links to specific trouble-shooting pages)


A step-by-step tutorial:

This page and its linked pages will allow you to walk through the 12.2.2 control system step-by-step, similarly as you would be taught at the beamline by a staff scientist or engineer.


As a user you will sit in front of 3 monitors and 2 sets of keyboard and mice.



Monitors 1 concerns the beamline operation, monitor 2 is a monitor extension of #1. It should facilitate cleaner LabView window arrangement during complex experiments. Monitor 3 (plus it's separate keyboard & mouse) concerns the control of the Mar345 image plate reader.

The mar terminal (#3) is separate for historic and trouble-shooting purposes, and will be explained separately. In general, all remote actions will be controlled by the experimenter from within one single PC, namely BL1222ACQ through monitor and keyboad & mouse 1.

3 other PC's are running in the background and will be accessed by the experimenter via VNC from within BL1222ACQ.

These are: 

  • BL1222BCS:
    This machine controls beamline-specific elements (BCS = Beamline Control System).
  • BL1222ES
    This 32 bit machine runs most of the motor drivers (which are often not compatible with the 64 bit BL1222ACQ). It runs in the background and you should only in exceptional cases have to restart something on it)
  • DEC2038
    This is a UNIX machine controlling the Pilatus detector. It is rarely needed except for sanity check to make sure the LabView - Dectris communication is still active.


Normally, when you enter the BL1222 control area, all control software will be started and set-up to start experiments.

If for some reason this is not the case, or you need to restart LabView on one of the three Windows machines (ACQ, BCS, ES), follow this link:


To connect from BL1222ACQ to BL1222BCS, BL1222ES or DEC2038 via VNC, follow these instructions
