1 INTRODUCTION
The CIO-DAS08/JR/16 combines analog inputs with digital input and output capability, while the CIO-DAS08/JR/16-AO version adds
two channels of analog output capability. The CIO-DAS08/JR/16 may be upgraded to a CIO-DAS08/JR/16-AO by purchasing and
installing the CIO-DUAL-DAC16 chip set.
1.1 DIGITAL OUTPUTS & INPUTS
There are eight inputs and eight outputs for sensing and controlling digital devices. They are port-addressable and are dedicated to
either input or output. The digital outputs and inputs are TTL level.
1.2 ANALOG INPUTS AND OUTPUTS
The CIO-DAS08/JR/16 provides up to eight single-ended analog inputs. In addition to the inputs, the CIO-DAS08/JR/16-AO version
can supply two analog voltage outputs. Sixteen-bit resolution is provided for analog inputs and outputs. The range is ±5V bipolar for
analog inputs (and outputs if used).
2 SOFTWARE INSTALLATION
The board has a bank of switches and a jumper to set before installing the board in your computer. By far the simplest way to configure
your board is to use the InstaCal
TM
program provided as part of your software package. InstaCal
TM
will show you all available options,
how to configure the various switches and jumpers to match your application requirements, and will create a configuration file that
your application software (and the Universal Library) will refer to so the software you use will automatically know the exact
configuration of the board.
Please refer to the Software Installation Manual regarding the installation and operation of InstaCal. The following information is
provided as a matter of completeness, and will allow you to do the hardware configuration of the board if you do not have immediate
access to InstaCal and/or your computer
.
3 HARDWARE INSTALLATION
3.1 BASE ADDRESS
The base address of either versionof the CIO-DAS08/JR/16 is set by switching
a bank of DIP switches. The bank of switches, labeled ADDRESS, is
numbered 9 to 3.
Ignore the word ON and the numbers printed on the switch
Board logic adds up the weights of individual switches to determine the base
address. A 'weight' is active when the switch is down. Shown to the right,
switches 9 and 8 are down, all others are up. Weights 200h and 100h are
active, totaling a 300h base address.
