Offering silent mode, error frame detection and an on-board buffer, the small form factor board fits any embedded data acquisition systems, but is particularly suitable for fleet management to monitor key parameters such as fuel economy, engine speed, braking and accelerator pressure, and gearshift patterns. The board supports a bit rate from 40 to 1000 kbit/s and a CAN transfer rate up to 20000 messages/s. Time stamp accuracy is 25 µs. It has a low profile connector that complies with the mini PCI Express standard, which connects via a cable to a DSUB connector (or other type) at the computer housing.
With just the CAN communication link itself exposed, this arrangement protects total system EMC performance because all the electronics remain inside the computer housing. This add-on board complies with EN 61000-6-2:2005, specifying EMC immunity for industrial environments and also operates over the industrial temperature range of -40 to +85°C. Kvaser’s free of charge CANLIB SDK can be used to develop software for the Mini PCI Express HS board. Support for Linux, in the form of drivers and a dedicated SDK, are available as a separate download.
