Configuring the CIO-DAC08
The CIO-DAC08 has one base address switch, one bank of gain switches for each analog output channel, a
simultaneous update jumper for each DAC pair, a "power-up state" selection jumper, and one wait state jumper
which you must set before installing the board in your computer. The InstaCal calibration and test program
included with the CIO-DAC08 will show you how to set the switches. Run InstaCal before you open your
computer and install the board.
