Configuring SSRL's DHS

SSRL uses a DHS program which supports the following hardware:

• DMC2180 motion controller.

• ADSC Quantum 4 CCD detector.

• ADSC Quantum Q315 CCD detector.

• MAR345 detector without a base.

• MARCCD family of detectors.

• Image analysis of JPEG's obtained by AXIS 2400 servers. (for automatic crystal centering)

1. Check out the Q4 image transformation files found in the xform project. These files contain some algorithms and code which Area Detector Systems Corporation does not wish to have distributed without prior permission.

   blctlxx:~/release-4_1 > cvs checkout -r release-4_1 xform
   cvs checkout: Updating xform
   U xform/xform.c
   U xform/xform.h
   blctlxx:~/release-4_1 >
   

   If you do not have access to this project, the xformstub.c and xformstub.h (provided by SSRL) can be used to build the DHS. Create the xform directory in your 'DCS root' directory before copying and renaming the follow the files as shown in this example:

   blctlxx:~/release-4_1 > mkdir xform
   blctlxx:~/release-4_1 > cd xform
   blctlxx:~/release-4_1/xform > cp ~/release-4_1/dhs/src/xformstub.c xform.c
   blctlxx:~/release-4_1/xform > cp ~/release-4_1/dhs/src/xformstub.h xform.h
   

2. DCSS must be explicitly configured to expect the DHS' connection.

   This is done by changing DCSS' database.dat file to expect the connection from the new DHS by making a DHS entry as discussed in The DHS definition.
