Introducing the CIO-DDA06/JR
Overview: CIO-DDA06/JR features
The CIO-DDA06/JR can have a maximum of six analog ±5Volt output channels (two are installed) and 24
digital inputs and/or outputs. The analog outputs are dual-DAC AD7237s. The CIO-DDA06/JR is 100%
register-compatible with the CIO-DDA06.
The analog outputs may be set for simultaneous update in groups of two, four or all six. Analog outputs aregrouped as 0 and 1, 2 and 3, and 4 and 5. By selecting XFER on the jumper beside the DAC, each pair can be
set for simultaneous transfer. In this way the CIO-DDA06/JR may be set to hold new values until all channels
are loaded, then update any two, any four, or all six channels simultaneously. This is a very useful feature formulti-axis motor control.
The CIO-DDA06/JR digital I/O lines are an emulation of the 82C55 chip in mode 0. The digital I/O isequivalent to a CIO-DDIO24H high drive digital I/O board. This is sufficient to switch other TTL or similar
inputs, as well as relays, LEDs or solid state relays.

Software features
For information on the features of InstaCal and the other software included with your CIO-DDA06/JR, 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/JR

Unpacking the CIO-DDA06/JR
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DDA06/JR 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/JR
The CIO-DDA06/JR has one base address switch and a simultaneous update jumper for each DAC pair. The
InstaCal calibration and test program will show you how to set the switches. Run InstaCal before you open
your computer and install the board. The CIO-DDA06/JR is shipped with the factory-default settings listed in
the table below.

Before installing the CIO-DDA06/JR 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/JR 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 default base address of 300 hex.

Guide Installing the CIO-DDA06/JR

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 are loaded with new
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 are dual DACs (two analog outputs per chip). A single jumper sets both DACs on asingle chip to be either simultaneously transferred on a read, or individually updated when the control register
is written. The jumpers are labeled J1, J2 or J3 on the board.
J1 sets the transfer mode for channels 0 and 1.
J2 sets the transfer mode for channels 2 and 3.
J3 sets the transfer mode for channels 4 and 5.

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-DDA06/JR 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.

Installing the CIO-DDA06/JR
After you configure the board's switches and jumpers, you can install the CIO-DDA06/JR 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.
1.

Turn your computer off, open it up, and insert your board into an available ISA slot.

2.

Close your computer and turn it on.

3.

To test your installation and configure your board, run the InstaCal utility you installed in the previous
section. Refer to the Quick Start Guide that came with your board www.mccdaq.com/PDFmanuals/DAQSoftware-Quick-Start.pdf for information on how to initially set up and load InstaCal.

Figure 4. I/O connector pin-out

The analog outputs of the CIO-DDA06/JR are two-wire hook-ups. Always use low-level ground (LLGND) as
the ground reference for all analog hook-ups. The output range of the CIO-DDA06/JR is ±5 volts and cannot bechanged. There are no trimming pots on the board so no hardware calibration is necessary or possible.

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