Using Keithley175 instrument support in an application

Several files need minor modifications to use Keithley175 instrument support in an application.

1. Add the full path to the Keithley175 support directory to the application configure/RELEASE file:
   Keithley175=xxxx/modules/instrument/keithley175/<release>
   Where <release> is the release number of of the Keithley175 support.
2. Add instrument support to application database definition file
   The application database definition file must include the database definition files for the Keithley175 instrument and for any needed ASYN drivers. There are two ways that this can be done:
   • If you are building your application database definition file from an xxxInclude.dbd file you include the additional database definitions in that file:
     include "base.dbd"
     include "devKeithley175.dbd"
     include "drvVxi11.dbd"    (or some other GPIB driver)
   • If you are building your application database definition file from the application Makefile your specify the aditional database definitions there:
     xxx_DBD += base.dbd
     xxx_DBD += devKeithley175.dbd
     xxx_DBD += drvVxi11.dbd    (or some other GPIB driver)
3. Add the Keithley175 support libraries to the application
   You must link the Keithley175 support library and the ASYN support library with the application. Add the following lines:
   xxx_LIBS += devKeithley175
   xxx_LIBS += asyn
   before the
   xxx_LIBS += $(EPICS_BASE_IOC_LIBS)
   in the application Makefile.
4. Load the Keithley175 support database records in the application startup script:
   cd $(Keithley175)      (cd Keithley175 if using the vxWorks shell)
   dbLoadRecords("db/devKeithley175.db,"P=<P>,R=<R>,L=<L>,A=<A>")
   You'll have to provide appropriate values for the PV name prefixes (<P> and <R>), the link number (<L>) and the device address (<A>). The link number must match the value specified in an ASYN xxxxxConfigure command.

Installation and Building

1. Create an installation directory for the module. The path name of this directory should end with modules/instrument/keithley175.
2. Place the distribution file into this directory.
3. Execute the following commands:
   cd modules/instrument/keithley175
   gunzip keithley175<release>.tar.gz
   tar xvf keithley175<release>.tar
   cd <release>
   Where <release> is the release number of of the Keithley175 support.
4. Edit the configure/RELEASE file and set the paths to your installation of EPICS base and ASYN.
5. Execute make in the top level directory.
