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.
