Chapter 1

Introducing the CIO-DAC08
Overview: CIO-DAC08 features
The CIO-DAC08 has 8 channels of 12-bit analog output (one D/A per channel). Analog outputs are dual-DAC
AD7273s (two analog outputs per chip), with each output buffered by an OP07. The CIO-DAC08 is compatible
with MetraByte's DDA-06 but lacks digital outputs. Software designed for the DDA-06 will operate the analog
outputs.
Analog output ranges are switch-selectable for a Bipolar or Unipolar range. Bipolar ranges are ±10 V, ±5 V,
and ±2.5 V. Unipolar ranges are 0 to 10 V, 0 to 5 V, and 0 to 2.5 V.
The analog outputs are controlled by writing a digital control word as two bytes to the DAC's control register.
The control register is double buffered so the DAC's output is not updated until the second byte (the high byte)
is written.
Each analog output pair is jumper-selectable for either individual or simultaneous update. When a DAC pair isset for simultaneous update, writing new digital values to the DAC's control register does not update the DAC's
voltage output. Update of the output occurs only after a READ from the board's addresses.
The board also features a wait state generator that you enable with an on-board jumper.

Software features
For information on the features of InstaCal and the other software included with your CIO-DAC08, refer to the
Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

Installing the CIO-DAC08

Wait state jumper
The CIO-DAC08 board has a wait state jumper which you can set to enable an on-board wait state generator.
A wait state is an extra delay injected into the processor's clock via the bus. This delay slows down theprocessor when the processor addresses the CIO-DAC08 board so that signals from slow devices (chips) will
be valid.
This jumper is shown in Figure 2 configured for OFF (wait state is disabled).

ON

OFF

Figure 2. Wait State jumper

The wait state generator on the CIO-DAC08 is only active when the CIO-DAC08 is being accessed. Your PC
will not be slowed down in general by using the wait state.

Individual / simultaneous update jumper
The analog output chips on the CIO-DAC08 are dual DACs (two analog outputs per chip). Each DAC channel
pair has an associated jumper that sets both DACs on a single chip to be either simultaneously transferred on aread (XFER), or individually updated when the MSB register is written.
The top of each jumper on the CIO-DAC08 board is labeled XFER. Below each jumper are two numbers thatindicate the pair of channels that the jumper selects (12, 34, 56, or 78). For example, "12" indicates channels
one and two.
Figure 3 shows the jumper block configured for each update mode.

Figure 3. Individual / simultaneous update jumperWhen the jumpers are in the XFER position, new output data is held until one or more DACs have been
loaded with new digital data. The new data transfers to the voltage outputs as a group. The simultaneoustransfers occur when any of the CIO-DAC08 addresses are read (and the jumpers are in the XFER
position).
Whenjumpered to the channel numbers, the DAC channel pair is individually updated.

CIO-DAC08 User's Guide

Installing the CIO-DAC08

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.

PWR UPZERO

STD

Figure 4. Power up and reset jumper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.
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, andindividual switches are labeled 1 through 5.
Set the switches for each individual channel as shown in Figure 5.

Programming and Developing Applications
After following the installation instructions in Chapter 2, your board should now be installed and ready for use.
In general there may be no correspondence among registers for different boards. Software written at the registerlevel for other models will not function correctly with your board.

Programming languages
Measurement Computing’s Universal Library provides access to board functions from a variety of Windows
programming languages. If you are planning to write programs, or would like to run the example programs for
Visual Basic or any other language, please refer to the Universal Library User's Guide (available on our website at www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf).

Packaged applications programs
Many packaged application programs now have drivers for your board. If the package you own does not have
drivers for your board, please fax or e-mail the package name and the revision number from the install disks.
We will research the package for you and advise how to obtain drivers.
Some application drivers are included with the Universal Library package, but not with the application package.
If you have purchased an application package directly from the software vendor, you may need to purchase ourUniversal Library and drivers. Please contact us by phone, fax or e-mail:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.
Fax: 508-946-9500 to the attention of Tech Support
Email: techsupport@mccdaq.com

Register-level programming
You should use the Universal Library or one of the packaged application programs mentioned above to control
your board. Only experienced programmers should try register-level programming.
If you need to program at the register level in your application, refer to the Register Map for the CIO-DAC08
and CIO-DAC16. This document is available on our website at www.mccdaq.com/registermaps/RegMapCIODAC08_16.pdf.

Chapter 4

Functional Details
Signal connections
Each of the CIO-DAC08 outputs are individually buffered through an OP07 operational amplifier (OP-AMP).
The OP07s are socketed so that if one fails it can be replaced in the field. The OP07 for each channel is locatedjust below the calibration potentiometers for that channel.
At the full rated output swing of ±10V, each channel is capable of sinking or sourcing ±5 mA. That means aload of 2K Ohms can be connected to each channel.
As the load resistance is raised from 2 K up to 10 MΩ or more, the output load on the DAC decreases. Anyload resistance greater than 2K is fine.
As the load resistance decreases, the output load increases. The OP07 responds by producing a lower output
voltage. If your CIO-DAC08 will not produce the output voltage specified by the code & range combination, it
is a good idea to check the load with an ohm meter.
Under normal circumstances you will not damage the OP07 by connecting the output to ground. If yourconnection results in a failure of the OP07, chances are good that there was some potential at the connecting
point in addition to a load at ground or between 0 and 2 K Ω. Explore the point with a DVM before
reconnecting the CIO-DAC08 (and after replacing the OP07 of course). Connect the negative lead of the DVM
to any LLGND pin of the CIO-DAC08.
