1 Introduction

The PCI/cPCI/PM-7841 is a Controller Area Network (CAN) inter-

face card used for industrial PC with PCI, Compact-PCI, and

PC104 bus. It supports dual ports CAN’s interface that can run

independently or bridged at the same time. The built-in CAN con-

troller provides bus arbitration and error detection with auto cor-

rection and re-transmission function. The PCI cards are plug and

play therefore it is not necessary to set any jumper for matching

the PC environment.

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

nally developed by Bosch for use in automobiles, is increasing

being used in industry automation. It multi-master protocol, real-

time capability, error correction and high noise immunity make it

especially suited for intelligent I/O devices control network.

The PCI/cPCI/PM-7841 is programmed by using the ADLINK‘s

software library. The programming of this PCI card is as easy as

AT bus add-on cards.

1.1 PCI/cPCI/PM-7841 Features

The PCI-7841 is a Dual-Port Isolated CAN Interface Card with the

following features:

XTwo independent CAN network operation

XBridge function supports

XCompatible with CAN specification 2.0 parts A and B

XOptically isolated CAN interface up to 2500 Vrms isolation

protection

XDirect memory mapping to the CAN controllers

XPowerful master interface for CANopen, DeviceNet and

SDS application layer protocol

XUp to 1Mbps programmable transfer rate

XSupports standard DeviceNet data rates 125, 250 and 500

Kbps

XPCI bus plug and play

XDOS library and examples included
