CIO-DDA06/16 User's Guide (this document) is also available on our web site at
The CIO-DDA06/16 has six channels of 16-bit analog output and 24 lines of digital I/O. The analog outputs are
from 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 by
programming the 8255's mode register. There are three possible modes. The simplest and most commonly used
mode is mode 0 — simple input and output.

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 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:

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 the
switches. 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.
ADDRESS DIP switch for setting the base address 300h (768 decimal)
J1 Jumper to select simultaneous or single channel update UPDATE position (single channel update)
S1 – S6 DIP switches to set the output range for each analog
output channel
Before installing the CIO-DDA06/16 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-DDA06/16 board.
±5V
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 factory-default base address of
300 hex.

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 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 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 simultaneously
transferred 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 to
each simultaneous transfer jumper (45, 23, and 01 from left to right). The numbers indicate which channel pair
is configured by the jumper (channels 0 and 1, 2 and 3, 4 and 5).

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-DDA06/16 addresses are read (and the jumpers are in the

position).

The analog outputs are two-wire hook-ups. Always use low-level ground (LLGND) as the ground reference for
all analog hook-ups.
All the digital outputs inputs are TTL level. Before connecting external devices, review the specifications in
this manual to avoid damage to the CIO-DDA06/16.
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 register
level for other models will not function correctly with your board.
