Chapter 1

Introducing the PCI-DAS4020/12

Overview: PCI-DAS4020/12 features

This manual explains how to install and use the PCI-DAS4020/12 board.

The PCI-DAS4020/12 is a multi-function high-speed data acquisition I/O board that is designed for the PCI bus. It provides the following features:

 Four high-speed 12-bit analog input channels

The input range for each channel is software-configurable for ±1 V or ±5 V. The sample rate is from 10 to 20 MHz, depending on the number of channels accessed. Triggering sources and A/D gating are via hardware or software, and can be internal or external. Four different modes are software selectable. Analog input connectors are standard BNC types.

 Two 12-bit analog output channels

Each analog output channel can be configured by software for an output range of ±10 V or ±5 V. Throughput is system-dependent. Triggering mode is software gate. D/A pacing is software paced. The analog output channels terminate at a 40-pin auxiliary connector.

 24 digital I/O channels

An on-board industry standard 82C55A I/O chip provides 24 digital I/O channels configured as two banks of eight and two banks of four. You can configure each bank independently as input or output. Signal levels are TTL. The digital I/O channels terminate at a 40-pin auxiliary connector.

Software features

For information on the features of InstaCal and the other software included with your PCI-DAS4020/12, refer to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
