Rolph,

In the SRICAT at the APS, we have a number of cameras which use a program I
wrote which uses Jeff's PCAS to interface to EPICS.

Currently, we're capable of controling nearly the entire line of Roper
Scientific cameras (both the PVCam interface used by the "Photometrics"
cameras and the easydll interface used by the "Princeton Instruments"
cameras), cameras from Andor Technologies and the MicroImagerII camera system
from QImaging Systems.  Also, it's reletively simple to add support for new
camera systems provided a device driver API is availiable.

This program currently only works on Win95/98/NT (it's never been tested under
2K) although I have considered porting it to Linux.  The major problem here is
that none of the camera systems we use have robust Linux drivers availiable.

It's not as full featured as one would like, but we've been using it on a
number of camera systems for almost two years now with reletively few
headaches.  One of the headaches is the 16KB array size limit of CA.  If R3.14
does indeed address this limit for the PCAS it would be much simpler to move
images over CA.

If anyone is interested in more specifics, I do have a user guide in MS Word
format I can send on request.
