Chapter 1

Introducing the PCI-DIO96H

Overview: PCI-DIO96H features

This manual explains how to install and use the PCI-DIO96H board. The PCI-DIO96H is a high-density, logiclevel digital I/O board designed for the PCI-bus.

The PCI-DIO96H provides 96-bits of digital I/O. The I/O is organized into four 24-bit groups based on an 82C55 mode 0 emulation. 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 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. Each board is equipped with open locations where you can install SIP resistor networks for either pull-up or pull-down.

The PCI-DIO96H 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-DIO96H, 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.
