Chapter 1
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 are
grouped 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 for
multi-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 is
equivalent 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 to
the 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

CIO-DDA06/JR User's Guide 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 by
simply 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 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
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-Software-
Quick-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.
Factory-configured default settings
Board label Switch/jumper description Default setting
ADDRESS
J1, J2, or J3
DIP switch for setting the base address 300h (768 decimal)
Jumpers to select simultaneous or single channel update
for each DAC channel pair
UPDATE position (single channel update)
Before installing the CIO-DDA06/JR in the computer, verify that the board is configured with the settings that
you 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 base
address switch is to let InstaCal show you the correct settings. However, if are already familiar with setting ISA
base 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. shows the base address switch set to its default base address of 300 hex. Figure 2

CIO-DDA06/JR User's Guide Installing the CIO-DDA06/JR
In the default configuration shown in Fi , 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
gure 2
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 a
single 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 simultaneous
transfers 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 the
control 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/DAQ-
Software-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 be
changed. There are no trimming pots on the board so no hardware calibration is necessary or possible.
