1 Introduction
The PCI/cPCI/PM-7841 is a Controller Area Network (CAN) interface 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 controller provides bus arbitration and error detection with auto correction 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 originally developed by Bosch for use in automobiles, is increasing
being used in industry automation. It multi-master protocol, realtime 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

following features:
X Two independent CAN network operation
X Bridge function supports
X Compatible with CAN specification 2.0 parts A and B
X Optically isolated CAN interface up to 2500 Vrms isolation
protection
X Direct memory mapping to the CAN controllers
X Powerful master interface for CANopen, DeviceNet and
SDS application layer protocol
X Up to 1Mbps programmable transfer rate
X Supports standard DeviceNet data rates 125, 250 and 500
Kbps
X PCI bus plug and play
X DOS library and examples included

2 Installation
This chapter describes how to install the PCI/cPCI/PM-7841. At
first, the contents in the package and unpacking information that
you should be careful are described.
2.1 Before Installing the PCI/cPCI/PM-7841
Your PCI/cPCI/PM-7841 card contains sensitive electronic components that can be easily damaged by static electricity.
The card should be done on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the
same point as the anti-static mat.
Inspect the card module carton for obvious damage. Shipping and
handling may cause damage to your module. Be sure there are no
shipping and handing damages on the module before processing.
After opening the card module carton, exact the system module
and place it only on a grounded anti-static surface component side
up.
Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your PCI/cPCI/PM-7841.
2.2 Installing PCI-7841
What you have:
In addition to this User's Manual, the package includes the following items:
X PCI-7841 Dual Port PCI Isolated CAN Interface Card
X ADLINK CD-ROM
If any of these items is missing or damaged, contact the dealer
from whom you purchased the product. Save the shipping materials and carton in case you want to ship or store the product in the
future.
