PCI Board Supports Four Controller Area Network (CAN) Channels
esd electronics, Inc. announces the release of the CAN-PCI/405-2 interface board providing access to up to four independent CAN channels.

The majority of industrial control applications based on CAN will require the use of higher layer protocols such as CANopen or DeviceNet, basically a protocol extension through additional software.
The board supports application requiring more than the usual single CAN channel, in this case up to four channels. The four channels can be assigned to support different baud rates for applications where, for instance, it is important to separate low-speed, low-priority signals (switches, etc.) from high-speed, high-priority signals (emergency services, etc.). Other application may require the monitoring of several independent CAN/CANopen networks.
The CAN - PCI/405 is a PC board designed with a PCI bus for the AMCC PowerPC 405 that operates at 200 MHz. This board is equipped with 32 Mbyte SDRAM and 2 Mbyte Flash. The CAN - PCI/405 uses PCI bus mastering to achieve high throughput and to relieve the main CPU.
esd electronics has designed the CAN - PCI/405 to provide two fully ISO 11898 compliant CAN interfaces based on SJA1000 CAN controllers, and high resolution hardware timestamps. Optionally, the CAN - PCI/405 offers an adapter board that accesses two additional CAN interfaces. The CAN interfaces allow a data transfer rate of 1 Mbit/s and are electrically isolated.
Software drivers are available for Windows, Linux, SGIIRIX6.5 and esd electronics, Inc. will make drivers for other operating systems available upon request. Higher Layer protocols such as CANopen and DeviceNet are available.
esd electronics, Inc. is a premier supplier of CAN modules including interfaces to systems such as PCI, CompactPCI, PMC, PCI Express, VME, USB, Ethernet, WLAN, Bluetooth and Profibus. Higher layer CAN protocols CANopen, DeviceNet, and SAE J1939 are supported for almost all interface boards. Moreover, almost any combination is available as a stand-alone gateway, especially for Ethernet.
Our hardware components are designed according to the highest industrial standards, and backed by a 2 year warranty.
All of our CAN components include complete opto-isolation (high-speed opto-couplers plus DC/DC converters) as a standard and they are 100% compliant to the CAN 2.0 A/B standard.
