Chapter 1
Introducing the CIO-DIO96
Overview: CIO-DIO96 features
The CIO-DIO96 is a 96-bit digital I/O board with four 82C55 parallel-interface chips. The board provides the
96 bits in 24-bit groups based on the 82C55 specification.
Each 82C55 chip controls 24 CMOS/TTL-compatible digital I/O pins. Each 24-bit group is divided into three
eight-bit ports, or two 8-bit ports and two 4-bit ports. Each port is programmable for input or output.
All I/O bits are set to input mode (high impedance) on power up and reset. Locations are available for installing
pull-up or pull-down resistors.
All signals pass through a 50-pin connector.
Software features
For information on the features of InstaCal and the other software included with your CIO-DIO96, 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.
Check www.mccdaq.com/download.htm for the latest software version.

CIO-DIO96 User's Guide Installing the CIO-DIO96
Unpacking the CIO-DIO96
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DIO96 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: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [e-mail]
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 base address switch
The CIO-DIO96 employs the PC bus for power, communications and data transfer. As such, it draws power
from the PC, monitors the address lines and control signals, responds to its I/O address, and receives and places
data on the eight data lines.
The CIO-DIO96 has one bank of base address-select switches, and one wait-state jumper. Verify their settings
before installing the board in your computer.
Base address switch
The easiest way to set the base address is to let InstaCal show you the correct settings. However, if you are
already familiar with setting ISA base addresses, you may use the base address switch description below to
guide your base address selection.
The base address is the starting location that software writes to when communicating with the CIO-DIO96. A
set of DIP switches is used to set the base address. By placing the switch down, the CIO-DIO96 address decode
logic is instructed to respond to that address bit. A complete address is constructed by calculating the HEX or
decimal number which corresponds to all the address bits the board has been instructed to respond to.
The board is shipped with the base address set to 300 hex (see ). Unless there is already a board in your
system that uses address 300 hex (768 decimal), leave the switches as they were set at the factory.

In the default configuration, 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).

You can set the base address switch to any address in the range of 000-3F8. If you are not using IBM
prototyping cards or another board which occupies these addresses, 300-31Fh are also free to use.
Addresses not specifically listed, such as 390-39Fh, are not reserved and may be available. Check your
computer for other boards which may use I/O addresses.
Wait state jumper
The CIO-DIO96 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-DIO96 board, so that signals from slow devices (chips) are valid.
The jumper is shown in configured for OFF (wait state is disabled).Figure 2

WAIT
STATE
The wait state generator is only active when the CIO-DIO96 is being accessed. Your PC will not be slowed
down in general by using the wait state.
Because all PC expansion board buses are slowed to either 8 MHz or 10 MHz, the wait state generally is not
required. If you experience sporadic failures, try enabling the wait state generator.
