Example 3: Configuring a Bridge Chain

Configuring a bridge chain is possible because every Slave can serve as Master for another
Slave.

To connect a third CAN bus by using an additional CANblue II to the CAN buses that are
configured in example 1 and 2, two options are possible:

•

connecting the Slave to the new device (Slave serves as Master for the new device)

•

connecting the new device to the Master (Master serves as Slave for the new device)

Fig. 14

Bridge chain configuration

Each additional CAN bus increases the rate of CAN messages on the Bluetooth connections and
reduces the maximum possible data rate of all connections.
