High-speed Multifunction Boards

1. Introduction

The PCIe-862x User Manual contains information about using the ICP DAS PCIe-862x Series data
acquisition (DAQ) boards with UniDAQ. PCIe-862x Series boards feature up to 16 Analog Input (AI)
channels, up to two Analog Output (AO) channels, up to 24 lines of digital input/output (DIO), and
two counters. This chapter provides basic information you need to get started using your PCIe-862x
Series boards.

1.1 Overview

The PCIe-8620/8622 is a powerful
multifunction board based on the PCI
Express. With a FIFO of 2048 samples, the
maximum sampling rate of PCIe-862x
Series is up to 200 kS/s with 8/16 16-bit A/D
converters simultaneously sampling on
each channel. The PCIe-862x Series has two
16-bit voltage output (D/A) channels, 4/12
digital input channels, 4/12 digital output
channels, and two PWM output channels.
PCIe-8620/8622 supports more kinds of trigger modes for A/D conversion: software trigger, internal
pacer trigger and external pacer trigger. The software trigger can acquire a sample whenever
needed, while the internal pacer saves CPU loading by triggering the sampling at pre-programmed
frequency. An external pacer can be used for triggering by external frequency source.
The PCIe-8620/8622 also includes an onboard Card ID switch that can be used to set a unique ID for
each board so that they can be instantly recognized if two or more boards are installed in the same
computer.
