Introduction
PISO-CAN/PEX-CAN/PCM-CAN Series User’s Manual (v2.6 Dec/2013) -------

The CAN (Controller Area Network) is a serial communication protocol,
which efficiently supports distributed real-time control with a very high level of
security. It is especially suited for networking "intelligent" devices as well as
sensors and actuators within a system or sub-system. In CAN networks, there
is no addressing of subscribers or stations in the conventional sense, but
instead prioritized messages are transmitted. As a stand-alone CAN controller,
PISO-CAN, PEX-CAN, and PCM-CAN represents an economic solution within
which an active CAN board can have two or four independent CAN bus
communication ports with either a 5-pin screw terminal connector or a 9-pin
D-sub connector. It can be a master/slave interface, and be applied in various
CAN applications. In addition, these CAN cards use the new NXP SJA1000T
and transceiver 82C250/251, which provide the bus arbitration and error
detection. The differences between these CAN cards are the interface of PC.
Some are for PCI interface, some are for PCI Express interface, and some are
for PCI-104 interface. To get the detail information for the features and the
specification of these CAN cards, please refer to the section 1.2 and 1.3.
