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.
