Chapter 1
Introducing the CIO-DIO48H
Overview: CIO-DIO48H features
The CIO-DIO48H provides 48-bits of digital I/O. The I/O is organized into two 24-bit groups based on an
82C55 mode 0 emulation. Each 24-bit group is divided into three eight-bit ports labeled An, Bn and Cn, where
n is either "1" for FIRSTPORT or "2" for SECONDPORT. Port C can be split into two four-bit nibbles — Port
C-HI and Port C-LO. Each of these ports may be individually programmed as input or output.
All digital inputs are LSTTL. The output signals are buffered high output drive TTL. The digital output drivers
are 74S244 chips that can sink 64 mA and source 15 mA. The input buffers are 74LS373 chips and have
standard high input impedance of the 74LS series devices.
On power up and reset, all I/O bits are set to input mode. 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 50-pin connector.
Software features
For information on the features of InstaCal and the other software included with your CIO-DIO48H, refer to

Unpacking the CIO-DIO48H
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the CIO-DIO48H 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

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-
Configuring the base address switch
The CIO-DIO48H employs the PC bus for power, communications and data transfer. 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-DIO48H has one bank of base address-select switches. 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-DIO48H. A
set of DIP switches is used to set the base address. By placing the switch down, the CIO-DIO48H 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 Figure 1). 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.

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.
Installing the CIO-DIO48H
After you configure the base address, you can install the CIO-DIO48H 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.
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.

Figure 2. I/O connector pin-out
All the digital inputs and outputs are TTL. Under normal operating conditions, the voltages on the I/O pins
range from near 0 volts for the low state, to near 5 volts for the high state. The voltages and currents of external
devices usually exceed these values. Because of this, external relays are usually employed to handle higher
current and voltage loads.
In addition to load matching, digital signal sources often need to be filtered or "de-bounced". Refer to the Guide
to Signal Connections for information on digital interfacing. This document is available at

Functional Details
82C55 emulation
The CIO-DIO48H emulates the 82C55 chip. The 82C55 emulation 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 output, it
could be turned on or off every time the board is reset.
To establish a consistent TTL level at power-up, use resistors tied to either +5V (pull-up) or ground (pull-
down). There are open locations for pull-up and pull-down resistor packs on the board.
Whenever an 82C55 emulation is powered on or reset, all pins are set to high-impedance input. Based on
standard TTL functionality, these inputs will typically float high, and may have enough drive current to turn on
external devices.
Consequently, if you have output devices such as solid state relays, they may be switched on whenever the
computer is powered on or reset. To prevent unwanted switching, and to drive all outputs to a known state after
power on or reset, pull all pins either high or low through a 2.2 K resistor.
Signal level control
To safeguard against unwanted signal levels, the devices being controlled by the CIO-DIO48H board should be
tied low or high as required by a 2.2K Ω resistor. In a 2.2K eight-resistor SIP pack, one side of all of the
resistors is connected to a single common point and brought out to a pin. The common line, usually marked
with a dot or line, is at one end of the SIP. The remaining resistor ends are brought out to the other eight pins

I/O Lines
Figure 4. Eight-resistor SIP schematic
Figure 5 shows a schematic of an SIP installed in both the pull-up and pull-down positions. Each port provides
10 holes in a line. The end labeled HI connects to +5V. The end marked LO connects to GND. The eight holes
in the middle (n0 –n7) connect to the eight lines of the port (A, B or C).

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 LO hole. 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-DIO48H 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-DIO48H 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.
The CIO-DIO48H provides digital I/O in groups of 48 bits. Many relay and solid-state relay (SSR) racks
provide only 24-bits of digital I/O. You can configure the CIO-ERB24 relay output board and SSR-RACK24
I/O module rack in a daisy chain configuration to use all of the digital I/O bits provided by the CIO-DIO48H
board. An example of the daisy chain configuration scheme for each board is shown on page 15.

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.
Programming languages
Measurement Computing's Universal Library provides access to board functions from a variety of Windows
programming languages. If you are planning to write programs, or would like to run the example programs for
Visual Basic or any other language, refer to the Universal Library User's Guide (available on our web site at
Packaged applications programs
Many packaged application programs now have drivers for your board. If the package you own does not have
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.
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
