The CANHub-AFxSx fiber CAN converter/hub series is equipped with 1-2 fiber interfaces and 1-2 electrical isolation twisted-pair interfaces. It can receive/transmit data between 2-4 independent CANs/fiber networks with different speed, filter unnecessary CAN information to reduce the subnet load, and transmit messages between subnets as the CAN router.
The intelligent fiber CAN converter/hub can improve the topological structure of the CAN network, lengthen communication distance and increase networking nodes. The fiber CAN interfaces enable it to be applied to high-interference environments and the twisted-pair CAN channels enable it to be adapted to the Baud rate function of the corresponding network.

Networking Devices Recommended by SIEMENS Fire Monitoring System
The connection between CANHUB-AF2S2 and SIEMENS fire monitoring host is shown as follows:
1.When configuring the CAN fiber converter/hub, users only need to correctly set channel Baud rate. The filtering setting should only be used as needed. The following figure shows that a certain 50kbps bus is lengthened to 1600m from 800m and only CAN1, fiber 1 and fiber 2 are allowed to communicate each other. Since the twisted-pair cable 1/2 are used when the fiber transmission delay occurs, the CAN transmission distance can be doubled at the same Baud rate due to using the fiber.
2.The configuration software can monitor the CAN operating status, and obtain bus errors in real time to help the field operators to determine the fault cause.
