Introduction<br />
The DM6425HR 32-channel, 12-bit, 500 kHz PC/104 dataModule turns your IBM AT-compatible cpuModule or<br />
other PC/104 computer into a high-speed, high performance data acquisition and control system.<br />
This manual is intended to help you install your new module and get it running quickly, while also providing<br />
enough detail about the module and its functions so that you can enjoy maximum use of its features even in the<br />
most complex applications. <strong>RTD</strong> assumes that you already have an understanding of data acquisition principles<br />
and that you can customize the example software or write your own application programs.<br />
