Chapter 1
Introducing the PCI-DIO48H
Overview: PCI-DIO48H features
This manual explains how to install and use the PCI-DIO48H board. The PCI-DIO48H is a logic-level digital
I/O board designed for the PCI-bus.
The PCI-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 —PORT A, B, and C. PORT C
can be split into two four-bit nibbles —C-HI and 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 74ABT244 chips that can sink 64 mA and source 15 mA. The input buffers are 74LS373 chips and have the
standard high input impedance of the 74LS series devices.
Digital I/O lines are accessible through a 50-pin header connector. The board has a slow blow fuse rated at
1 amp that protects the +5 V User Output on the connector. One spare fuse is provided.
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. Each board is equipped with open locations where you can install SIP
resistor networks for either pull-up or pull-down.
The PCI-DIO48H board is completely plug-and-play, with no jumpers or switches to set. All board addresses
are set by the board's plug-and-play software. Board configuration is controlled by your system's BIOS.
Software features
For information on the features of InstaCal and the other software included with your PCI-DIO48H, 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 or versions of the software supported
under less commonly used operating systems.

PCI-DIO48H board
Additional documentation
In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of
the software you received with your MCC Hardware and information regarding installation of that software.
Please read this booklet completely before installing any software or hardware.
Optional components

Signal termination and conditioning accessories
MCC provides signal termination products for use with the PCI-DIO48H. Refer to Field wiring, signal
termination and conditioning on page 12 for a complete list of compatible accessory products.
Unpacking the board
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-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
phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [email protected]
For international customers, contact your local distributor where you purchased the PCI-DIO48H. Click on this
link www.measurementcomputing.com/sales.asp to locate your distributor.
Installing the software
Install the software included with your board before you install the hardware. Installing the software first
ensures that the information required for proper board detection is installed and available at boot up.
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.
Installing the hardware
The PCI-DIO48H board is completely plug-and-play. There are no switches or jumpers to set on the board.
Configuration is controlled by your system's BIOS. To install your board, 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 PCI slot.
2. Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or
Windows XP), a dialog box opens as the system loads, indicating that new hardware has been detected. The
information file for this board should have already been loaded onto your PC when you installed the
Measurement Computing Data Acquisition Software CD supplied with your board, and should be detected
automatically by Windows. If you have not installed this software, cancel the dialog and install it now.
3. To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up and
load InstaCal.
