config file that has the most motors, as you will have to add motors from theother geometries to the remaining config file.(3) Set up hard links in all the geometry directories so that the config and settingsin all the geometry directories refer to the same file. For example, if thefiles already exist in the fourc directory,use the commandsln fourc/config surf/configln fourc/settings surf/settingsto create hard links in the surf directory. Don’tuse symbolic links.(4) Edit the config file by hand to add new control lines that assign numbers tothe different geometries. These control lines must be before the lines thatassign motor information. The format of the geometry control lines is as follows:GEO0 = commonGEO1 = fourcGEO2 = surfGEO3 = fivecetc.The parameter GEO0 always refers to the motors that are common to all thegeometries. Subsequent lines assign consecutive numbers to the other geometries.(5) Now run edconf. The motor screen will have a new field that lets you assign aspectrometer geometry to each motor or to make the motor in common withall the spectrometers. Youcan do the same for each scaler on the scalerscreen (as of release 4.03.12).The hard links must be maintained for the shared config and settings file scheme towork. You can safely use vi and cp to manipulate the files. However, using mv willdestroy the links. Also, the editor ned will destroy the links.When running edconf with a geometry directory as an argument or when invokingthe config macro from spec, use the G command to toggle between displaying all themotors and scalers in the config file and just those motors and scalers used by thegiven geometry.INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION ADMINISTRATOR’S GUIDE 209
