Power up and reset jumper
The power up and reset jumper (hardware revision 3 and later) controls the state of the DAC outputs when the
CIO-DAC08 board is powered up or reset. This jumper is shown in
. Figure 4
Figure 4. Power up and reset jumper
ZERO STD
PWR UP
ƒ When set for ZERO , all DACs are cleared to 0 volts, ±32 mV on power up and reset. In addition, all DACs
are set to simultaneous update mode until first read.
ƒ When set for STD , the analog output values are undefined on power up and reset.
Analog output range switch
The analog output voltage range of each channel can be set with a set of five ganged DIP switches. The switch
blocks are located on the board below the calibration potentiometers. The switch blocks are labeled
0 to 7 , and
individual switches are labeled 1 through 5 .
Set the switches for each individual channel as shown in Figure 5.

To set a channel to a particular range, read the switch positions as UP or DN (down) from left to right in the
row beside the range you want to set.
The switch shown in Fi is configured for ±5V range (switch settings UP>DN>DN>UP>DN).
Installing the CIO-DAC08
After you configure the board's switches and jumpers, you can install the CIO-DAC08 into your computer. To
install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install
the MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on
installing the software.
