Configurable CAN/CAN Bridge

The CANbridge allows the coupling of two CAN networks, including networks with different bit rates. Unlike a CAN Repeater, which only translates the electric signals, the CAN messages are received completely by the CANbridge and then sent to the other CAN network in line with existing filter and conversion rules (Store-Forward pri

nciple). With the aid of conversion rules (gateway tables), CAN messages can be filtered or forwarded under another identifier. With these mechanisms, the bus load can be reduced in the individual networks by only sending messages which are of interest to the other network.

The CANbridge has a powerful 16-bit microcontroller that can process bursts at higher data rates without message loss. LEDs signal the current status of the coupled networks.

The CANbridge is available in three different versions: as an industrial version in either a DIN rail housing or in a robust metal housing, and as an automotive version in a robust metal housing.

Configuration

The configuration of the CANbridge can either be made using a configuration file, which is uploaded to the device via RS232 by an upload program included in the scope of delivery, or by using a special Windows gateway configuration tool. The Windows gateway configuration tool enables an easy and quick drag&drop configuration either free or based on CANdb bus description files.
