Controller Area Network (CAN) is applied as an embedded communication system for intelligent devices in factories, medical equipment and even as an internal bus. So transmitting high-speed CAN data into a desktop PC is sometimes necessary for programmers, project engineers and diagnostic technicians.
The CANPCI adapter, both cost-effective and versatile, is designed for either 5 V or 3.3 V bus operation for PCI compatible computers. The CANPCI adapter supports 8-bit transfers and takes advantage of the high-speed PCI bus for high data transfer speed.
This design is based on the ever-popular Philips SJA1000 CAN stand-alone controller chip, which is employed in both automotive and industrial applications. The SJA1000 affords more benefits than its predecessor, the 82C200. It can operate in the BasicCAN mode-or PeliCAN mode, which supports the cAN 2.0B specification with 29-bit identifiers. The SJA1000 operates from a 16 MHz clock and features a larger receive buffer and better acceptance-filtering. Data rates are possible up to 1 Mbps.
The newer PeliCAN mode is equipped with various features: error counters with read/write access; programmable error warning limit; last error register; error interrupt for each CAN-bus error; arbitration lost interrupt with detailed bit position; single-shot transmission (no retransmission); listen-only mode (no acknowledge, no active error flags); acceptance-filter extension (4-byte mask); and reception of "own" messages (self-reception request).
The CANPCI is available in two models: the CANPCI-DN incorporates the DeviceNet physical layer, whereas the CANPCI-CO provides a CANopen physical layer.
Optically-isolated transceivers offer reverse-voltage and short-circuit protection for both the CANPCI-DN (implementing the DeviceNet 5-position, open-style connector) and the CANPCI-CO (implementing the CANopen DB-9 connector).
