The I-2534 is a CAN switch used to establish a connection among four CAN bus sub-networks. In order to solve the problem of the star topology within the CAN network, the I-2534 is specially designed for integrating four CAN networks or solving the star topology. Not just like general CAN repeater, the I-2534 has three more important features.
(1) Extending CAN bus working distance.
(2) Connecting four CAN sub-networks with different baud rate.
(3) Support Star or Tree topology.

The transmission distance limitation of the CAN bus system on each port of the I-2534 is independent, which means the total CAN network distance can be extended by routing mechanism as the figure below.

The I-2534 could transfer CAN messages among four independent CAN networks. When the CAN bus system on one port of the I-2534 has some error (e.g. bus short), the system on the other three ports still work on correctly. Besides, the I-2534 provides message filter to avoid the influence of the network with low baud. The baud rate of four CAN ports can be different for highly flexibility as shown in the following figure.

In general, users use the daisy-chain method to connect all CAN devices in their applications. In some cases, the Star or Tree topology may be needed. The I-2534 which has four independent CAN ports could solve the topology problem of the CAN network. The following two figures show the CAN network with Star topology and Tree topology.

Besides, I-2534 provides the friendly utility tool for user-defined baud rateBroute path and filter configuration. When users use the I-2534 on two or more CAN networks which have different CAN baud rate, the route path and CAN filter may be useful to reduce the bus loading on the network with lower baud rate.
