BUNCH CLOCK GENERATOR / BCG100
			   Sample IOC Application
			            1.20
				January 2005


INTRODUCTION
This application serves as a sample IOC application for the VME-based
BCG100 and the Bunch Clock Generator (BCG). It provides instructions of
how to extract the sources and build the application for a beamline IOC.

The application was created as described in 'Chapter 2: Getting Started'
from the 'EPICS Input / Output Controller Application Developer Guide.'
It is intended for VxWorks-based IOCs and is compatible with EPICS base
versions 3.14.6 and 3.14.7 and provides a reasonable application departure
point.

The application requires the sequencer and is part of this distribution.
The sequencer (seq) was taken from synApps 5.0 and is version 2-0-8. In
addition, the sequencer must be built before the application. Refer to
the instructions below.

The distribution is archived in tar format and compressed using zip. It can
be downloaded from the BCDA website (internal) or is available upon request.
The intention is for the application to reside at the same level as EPICS
base with the following structure, however it can be extracted to any
structure.

    EPICS/
        base-3.14.6/
	base-3.14.7/
	bcg/
	    bcgApp/
	        Db/
	        op/
	        src/
	    configure/
	    documentation/
	    iocBoot/
	        iocbcg/
	    seq/
	        2-0-8/


INSTALLATION
Use the below steps to extract and build the application (assuming the
above structure):
   1)  cd EPICS
   2)  gzip -cd bcgApp.tar.gz | tar -xf -
   3)  cd bcg
   4)  Modify EPICS_BASE in ./configure/RELEASE
   5)  Modify the BCG100 settings in ./iocBoot/iocbcg/st.cmd
   6)  cd seq/2-0-8
   7)  Execute make (Linux) or gnumake (Solaris)
   8)  cd ../..
   9)  Execute make (Linux) or gnumake (Solaris)
   10) Set the IOCs boot parameter startup script to the path of st.cmd
   11) Reboot the IOC
