The systems have been tested with a direct interface program named ITLGuider.  This is a LabVIEW program which calls a DLL containing the library and driver code without a server.  It operates in local mode only.

All systems will eventually use AzCamServer to control hardware.  This program contains a library of camera functions and a hardware driver for the PCI interface card.  It uses a network socket communication interface for control by a remote client.  Images may be written to disk locally or remotely as FITS files, or binary images may be sent to a remote client.  The current custom version of AzCamServer for the PEPSI guiders is not for general release at this time.

Each PC controls two guider systems simultaneously and therefore has two copies of AzCamServer running, each accessed by a different socket port (2402 and 2403 by default).  All server PCs run Windows XP SP2.

The systems have been tested with "guider.tcl", a Tcl/Tk guider client written by Dr. Gary Schmidt at Steward Observatory which is used for autoguiding at Steward telescopes.  One system was taken to the University of Arizona 61" Kuiper telescope and performed actual autoguiding over a period of several nights.

The GCAM DSP assembly code used for PEPSI guiders checkout is gcam_ccd57.asm.
