CIO-DAS08 User's Guide Installing the CIO-DAS08
Configuring the CIO-DAS08
The CIO-DAS08 has two sets of switches and two jumpers that should be set before installing the board in the
PC. Mounted on the board is a bank of DIP switches for setting the base address, a jumper for setting the
interrupt level and a jumper for setting the pacer source to either the internal PC Clock source or an external
clock. A bank of four switches on the connector bracket is used for setting the analog input range.
The InstaCal calibration and test program included with the CIO-DAS08 will show you how to configure the
board. Run InstaCal before you open your computer and install the board.
The location of each switch and jumper on the CIO-DAS08 is shown in . Figure 1
