The I-2534 / I-5534-M is one kind of CAN bus switch. There are four independent CAN channels which offer a flexible design of the start or tree network topology. This new topology could resolve the complex CAN bus application, like industrial machinery, building automation, vehicle automation, and etc. Furthermore the I-2534 / I-5534-M integrates and exchanges data between different CAN network which has different baud rate. It helps users to extend the CAN network system. The I-2534 / I-5534-M could increase the maximum CAN node count in a CAN network by splitting the CAN network into several subnets. In additional, the user-defined CAN baud rate and CAN filter configuration are also supported.
