Chapter 1
Introducing the CIO-DIO24
Overview: CIO-DIO24 features
The CIO-DIO24 has 24 digital I/O connections, and one 82C55 parallel-interface chip.
Each 82C55 chip controls 24 CMOS/TTL-compatible digital I/O pins. The 82C55 is configured as 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. If you are using the board to control
items that must be OFF on reset, install pull-down resistors. The board is equipped with open locations where
you can install SIP resistor networks for either pull-up or pull-down.
All signals pass through a 37-pin connector.
Software features
For information on the features of InstaCal and the other software included with your CIO-DIO24, 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

Unpacking the CIO-DIO24
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DIO24 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.

Configuring the CIO-DIO24
The CIO-DIO24 has a bank of base address-select switches, an interrupt level select jumper, and a wait-state
jumper. The InstaCal calibration and test program included with the CIO-DIO24 will show you how to
configure the board. Run InstaCal to verify or change their settings before installing the board in your
computer.
The location of each switch and jumper on the CIO-DIO24 is shown in Figure 1.

interference with other installed boards, each board must use unique addresses. The base address is the board’s
starting location that software writes to when communicating with the CIO-DIO24. A set of DIP switches is
used to set the base address. By placing the switch down, the CIO-DIO24 address decode logic is instructed to
respond to that address bit. A complete address is constructed by calculating the HEX or decimal number whi
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 Figure 2

Wait state
The CIO-DIO24 board has a wait state jumper which you can set to enable an on-board wait state generator
(see Figure 4). 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-DIO24 board, so that signals from slow devices
(chips) will be accepted. The wait state generator is only active when the CIO-DIO24 is being accessed. Your
PC will not be slowed down in general by using the wait state.

Because all PC expansion board busses are slowed to either 8 MHz or 10 MHz, the wait state will generally not
be required. If you experience sporadic errors from the 82C55 digital I/O chip (reset, port direction swaps), try
enabling the wait state generator.
Installing the CIO-DIO24
After you configure the base address, you can install the CIO-DIO24 into your computer. 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.

Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections. This document is available on our web site at www.mccdaq.com/signals/signals.pdf.

Chapter 3
Functional Details
All of the digital outputs and inputs are CMOS TTL (Transistor-Transistor Logic). TTL is an industry term that
describes a standard for digital signals which are either at 0 V or 5 V (nominal).
The voltages and currents associated with external devices range from less than a hundred mA at a few volts for
lamps etc., to 50 Amps at 220 volts for electric heaters or other high-load equipment. Attempting to connect
such loads directly to the CIO-DIO24 will damage the I/O chip. Heavy loads such as these require external
relays.
Digital Interfacing
In addition to load matching, digital signal sources often need to be filtered or "de-bounced". Refer to the Guide
to Signal Connections at www.mccdaq.com/signals/signals.pdf for information on digital interfacing.
Signal level control
The 82C55 digital I/O chip initializes all ports as inputs on power- up and reset. A TTL input is a high
impedance input. If you connect another TTL input device to the 82C55 it could be turned ON or OFF every
time the 82C55 is reset.
To prevent unwanted signal levels, and to drive all inputs on the device you are controlling to a known state
after power up or reset, install pull-up or pull-down resistors. If you are using the board to control items that
must be OFF on reset, install pull-down resistors.
A pull-up resistor pulls all digital pins up to +5 V (high logic level). A pull-down resistor pulls all digital pins
down to 0 V (low logic level).
The CIO-DIO24 has open locations where you can install a single inline package (SIP) resistor network for
each port. When installed, the SIP establishes either a high or low logic level at each of the I/O lines on the
port.
The SIP is made up of eight 2.2 KΩ resistors. One side of each resistor is connected to a single common point
and brought out to a pin. The common line is marked with a dot or line at one end of the SIP. The remaining
resistor ends are brought out to the other eight pins (see Figure 8).

To pull-up lines, orient the SIP with the common pin (dot) toward the HI end; to pull-down, install the resistor
with the common pin in the

When installing pull-up and pull-down resistor SIP packs, we recommend using 2.2K, eight-resistor Single
Inline Packages (MCC part number SP-K2.29C). Use a different value only if necessary.
Unconnected inputs float
Unconnected inputs typically float high, but not reliably. If you are using a CIO-DIO24 for input and have
unconnected inputs, ignore the data from those lines. You do not have to terminate input lines. Unconnected
lines will not affect the performance of connected lines. Mask out any unconnected bits in software.
Digital I/O Isolation
To provide external signal conditioning and isolation, you can connect the CIO-DIO24 to a CIO-ERB24 or
SSR-RACK24. The CIO-ERB24 provides 24 Form C electromechanical relays. The SSR-RACK24 is a
mounting rack for 24 solid-state relays.

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 register
level for other models will not function correctly with your board.

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.
or any other language, refer to the Universal Library User's Guide (available on our web site at

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 our
Universal Library and drivers. Please contact us by phone, fax or e-mail:

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
