Chapter 1
Introducing the PCI-DUAL-AC5
Overview: PCI-DUAL-AC5 features
The PCI-DUAL-AC5 is a 48-bit, high output, digital I/O board for PCI-compatible computers. Primarily
designed as a direct interface to the industry-standard SSR-PB24 rack, the board is also highly useful as a
general purpose digital I/O board.
The 48-bits of digital I/O are organized into two 24-bit groups based on an 82C55 mode 0 emulation (no
strobed I/O or bi-directional I/O bits). Each 24-bit group is divided into three eight-bit ports labeled PORTA,
PORTB and PORTC. PORTC 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 inputs and outputs are TTL compatible. 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. All I/O is brought out to a 100-pin connector, which also allows connection to the PC’s +5 Volt
and Ground.
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-DUAL-AC5 board is completely plug-and-play, with no jumpers or switches to set. All board
addresses and interrupt sources 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-DUAL-AC5, 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.

Unpacking the board
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DUAL-AC5 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]
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.
Installing the PCI-DUAL-AC5
The PCI-DUAL-AC5 board is completely plug-and-play. There are no switches or jumpers to set.
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 pops up as the system loads indicating that new hardware has been detected. If the
information file for this board is not already loaded onto your PC, you will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software CD and click OK.
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.
