Chapter 1

Introducing the CIO-DDA06

Overview: CIO-DDA06 features

The CIO-DDA06 has six channels of 12-bit analog output and 24 lines of digital I/O. Analog outputs are dual­DAC AD7273s (two analog outputs per chip), with each output buffered by an OP07. Digital I/O is performed with one 82C55 chip. The CIO-DDA06 is 100% compatible with MetraByte's DDA-06.
Analog output ranges are switch-selectable for a Bipolar or Unipolar range. Bipolar ranges are ±10 V, ±5 V, ±2.5 V, and ±1.67 V. Unipolar ranges are 0 to 10 V, 0 to 5 V, 0 to 2.5 V, and 0 to 1.67 V.
Analog outputs are grouped in pairs (0/1, 2/3, and 4/5). Each analog output pair is jumper-selectable for either individual or simultaneous transfer in groups of two, four, or all six.
When a DAC pair is set for simultaneous update, the CIO-DDA06 may be set to hold new values until all channels are loaded, then update any two, four, or all six channels simultaneously.
The CIO-DDA06 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.
The power up and reset state is jumper-selectable (hardware revision 3 and later). You can also enable a wait state generator with an on-board jumper.

Unpacking the CIO-DDA06

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the CIO-DDA06 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

The CIO-DDA06 has one base address switch, one bank of gain switches for each analog output channel, a simultaneous update jumper for each DAC pair, a "power-up state" selection jumper, and one wait state 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 is shipped with the factory-default settings listed in the table below.
Factory-configured default settings

Before installing the CIO-DDA06 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 CIO­DDA06 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 factory-default base address of

When setting the base address, refer to the numbers printed in white on the printed circuit board.

Wait state jumper

The CIO-DDA06 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 the processor when the processor addresses the CIO-DDA06 board so that signals from slow devices (chips) will be valid.
This jumper is shown in configured for OFF (wait state is disabled). Figure 2
ON
Figure 2. Wait State jumper
OFF
The wait state generator on the CIO-DDA06 is only active when the CIO-DDA06 is being accessed. Your PC will not be slowed down in general by using the wait state.

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 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).

Signal connections

The CIO-DDA06 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 located just below the calibration potentiometers for that channel.
At the full rated output swing of ±10 V, each channel is capable of sinking or sourcing ±5 mA. A load of 2 K can be connected to each channel. As the load resistance rises from 2 K up to 10 M or more, the output load on the DAC decreases. Any load resistance greater than 2 k is acceptable.
