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 under
consideration of filter and conversion rules (Store-Forward principle).
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 to the other network which are of
interest.
The CANbridge has a powerful 16-bit microcontroller that
can process bursts at higher data rates without message loss. LEDs
show the current status of the coupled networks.
The CANbridge is
configured via serial interface with a convenient Windows program. The
configuration of the CAN-interfaces, setting of the operating modes and
the filter- and conversion tables are saved on the bridge.
The
CANbridge is available in three different versions: as an industrial
version in a top hat rail housing or in a robust metal housing and as an
automotive version in a robust metal housing.
There is also a CANbridge Adapter Developers Kit, which is described at the bottom of this page.
