Chapter 1

Introducing the CIO-DDA06/16
Overview: CIO-DDA06/16 features
The CIO-DDA06/16 has six channels of 16-bit analog output and 24 lines of digital I/O. The analog outputs arefrom AD660 DACs, with each output buffered by an OP27. Digital I/O is performed with one 82C55 chip.
Analog output ranges are switch-selectable for a Bipolar or Unipolar range. Bipolar ranges are ±10 V and ±5 V.
Unipolar ranges are 0 to 10 V and 0 to 5 V.
The analog outputs are jumper-selectable for either individual or simultaneous transfer. When a DAC pair is set
for simultaneous update, writing new digital values to the DAC's control register does not update the DAC's
voltage output. In this way, the CIO-DDA06/16 may be set to hold new values until all channels are loaded,then update all six channels simultaneously. This is a very useful feature for multi-axis motor control.
The CIO-DDA06/16 digital I/O lines are a direct interface to an 82C55. The 82C55 is a CMOS chip with TTL
level inputs and outputs. The 8255 can source or sink about 2.5 mA. This is adequate to switch other TTL or
similar inputs, but is inadequate to drive relays, LEDs or solid state relays. The digital I/O is controlled byprogramming the 8255's mode register. There are three possible modes. The simplest and most commonly used
mode is mode 0 — simple input and output.

Software features
For information on the features of InstaCal and the other software included with your CIO-DDA06/16, refer tothe Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.

Installing the CIO-DDA06/16

Unpacking the CIO-DDA06/16
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DDA06/16 from its packaging, ground yourself using a wrist strap or bysimply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately byphone, 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

Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-SoftwareQuick-Start.pdf.

Configuring the CIO-DDA06/16
The CIO-DDA06/16 has one base address switch, one bank of gain switches for each analog output channel,
and one simultaneous update jumper. The InstaCal calibration and test program will show you how to set theswitches. Run InstaCal before you open your computer and install the board.
The CIO-DDA06/16 is shipped with the factory-default settings listed in the table below.

Before installing the CIO-DDA06/16 in the computer, verify that the board is configured with the settings thatyou want. Review the following information to change the default configuration of a jumper or switch on the
CIO-DDA06/16 board.

Base address switch
Set the base address with the dip switch labeled ADDRESS located on the board. The easiest way to set the baseaddress switch is to let InstaCal show you the correct settings. However, if are already familiar with setting ISAbase addresses, you may use the base address switch description below to guide your base address selection.
Unless there is already another board in your system using address 300 hex (768 decimal), leave the switches as
they are set at the factory. Figure 2 shows the base address switch set to its factory-default base address of
300 hex.

Figure 2. Base address switch

In the default configuration shown in Figure 2, addresses 9 and 8 are DOWN, and all others are UP.
Address 9 = 200 hex (512 decimal), and address 8 = 100 hex (256 decimal). When added together they equal
300 hex (768 decimal).
Disregard the numbers printed on the switch
When setting the base address, refer to the numbers printed in white on the printed circuit board.

Individual / simultaneous transfer jumper
The analog outputs can be jumpered so that new output data is held until several DACs have been loaded withnew digital data. Then, as a group, the data for each DAC is simultaneously transferred and the DAC voltage
outputs are updated when any of the addresses BASE + 0 to BASE + B are read.
The analog output chips on the CIO-DDA06/16 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 simultaneouslytransferred on a read, or individually updated when the control register is written.
Figure 3 shows the jumper block configured for each update mode. Two numbers are listed on the board next toeach simultaneous transfer jumper (45, 23, and 01 from left to right). The numbers indicate which channel pairis configured by the jumper (channels 0 and 1, 2 and 3, 4 and 5).

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-DDA06/16 addresses are read (and the jumpers are in the XFER
position).
When the jumpers are in the UPDATE ## position, the DAC channel pair is individually updated when thecontrol register is written.

Analog output range switch
The analog output voltage range of each channel can be set with a set of five-position DIP switches. The switch
blocks are located on the board below the calibration potentiometers. The switch blocks are labeled S1 to S6,
and individual switches are labeled 1 through 5. Set the switches for each individual channel as shown in
Figure 4.

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 CIODDA06/16. This document is available on our website at www.mccdaq.com/registermaps/RegMapCIODDA06-16.pdf.
