The above software drivers are shipped with the card. Please refer to the
“Software Installation Guide” in the package to installthese drivers.
In addition, ADLINK supplies ActiveX control software DAQBench.
DAQBench is a collection of ActiveX controls for measurement or auto-
mation applications. WithDAQBench, you can easily develop custom user
interfaces to display your data, analyze data you acquired or received from
other sources, or integrate with popular applications or other data sources.
For more detailed information about DAQBench, please refer to the user's
guide in the CD.
(\Manual_PDF\Software\DAQBench\DAQBenchManual.PDF)
You can also get a free 4-hour evaluation version of DAQBench from the
CD.
