Chapter 1 Introduction

1.1 Description

PCI-1680U is special purpose communication card that offers connectiv-

ity to Controller Area Networks (CAN) on your PC. With its built-in

CAN controllers, the PCI-1680U provides bus arbitration and error detec-

tion with an automatic transmission repetition function. This drastically

reduces the chance of data loss and ensures system reliability. You can

run both CAN controllers independently at the same time. The PCI-

1680U operates at baud rates up to 1 Mbps and can be installed in a PC

expansion slot.

1.1.1 Controller Area Network

The CAN (Controller Area Network) is a serial bus system especially

suited for networking "intelligent" I/O devices as well as sensors and

actuators within a machine or plant. Characterized by its multi-master

protocol, real-time capability, error correction, high noise immunity, and

the existence of many different silicon components, the CAN serial bus

system, originally developed by Bosch for use in automobiles, is increas-

ingly being used in industrial automation.

1.1.2 Universal PCI

PCI-1680U provides truly universal connectivity, enabling a single prod-

uct to be used to implement systems with dramatically different resource

requirements. This makes PCI-1680U the most robust, most flexible, and

most economical choice for any application requiring isolation. PCI-

1680U uses a universal PCI connector compatible with both new 3.3 V

signaling support required for plug-in boards by the PCI 2.2 specification

and the 5 V signaling still used by many systems.

1.1.3 Optical Isolation Protection

On-board optical isolators protect your PC and equipment against dam-

age from ground loops, increasing system reliability in harsh environ-

ments.
