The file GM700.llb contains the LabVIEW VISA driver VIs for the
Cryomagnetics Hall Effect Gaussmeter GM-700. 

GM700Dem.llb contains a LabVIEW interactive user interface that provides 
an example for using the lower level VIs.  Although this is a functional 
interface for remotely controlling and monitoring one or more GM-700's, no 
attempt has been made to optimize throughput or minimize overhead. To operate
two GM-700's a copy of "GM-700 Operate.vi" may be saved as "GM-700 Operate II.vi",
and both copies executed simultaneously.

These VI libraries were developed on a PC-based Windows 95 system using
LabVIEW Version 4.1, and were tested using both IEEE-488 and RS-232.  Minor 
modifications may be necessary for use on other platforms.  The libraries have
been recompiled with version 6.1 under Windows XP.

The following VIs are provided, and are categorized by function. The Application
VIs use the lower level VIs to provide a high level, multi-instance programming
interface. The Application VIs together with the Initialize and Close VIs may
provide all the functionality needed for controlling and monitoring one or more
GM-700's.
