Communications with the IQM-233 card are through a provided 32-bit or 64-bit
DLL, placed in the Windows system directory. A description of each DLL function
is listed in

section 4.2, DLL Functions, on page 4-2

.

A LabVIEW VI sample is provided on the Thin Film Manuals CD to demonstrate the
syntax for calling the DLL. See

section 4.3, LabVIEW VI Sample, on page 4-7

.

The optional IQS-233 Codeposition software can be used as the user interface.
This software provides multi-layer processes, graphing, data logging, and digital
I/O (with external PLC). IQS-233 Codeposition software can be controlled from
customer-designed software by ASCII text commands. Contact INFICON for more
information regarding the optional IQS-233 Codeposition software.
