CAN communication router SBR FX series

dataEthernetTCP/IP

CAN fiber optic router SBR FX transmits data between CAN networks using optical fiber. To achieve the connection two devices are linked back-to-back. The transmission protocol used on the optical fiber is the reliable TCP/IP protocol. The use of TCP/IP abrogates the length/datarate restrictions, the typical error handling mechanisms of CAN are preserved within the single subnets. Depending on the type of the device, extensions up to 15 km or 40 km are possible.SBR FX includes a Samsung S3C4510B (ARM7 core) with 50 Mhz clock and a Linux operating system. In addition, the device has 16 MB SDRAM and 2 MB Flash. The connection to the CAN bus is done by a CAN controller of type NXP SJA1000 which supports the CAN protocols 2.0A and 2.0B.The use of Embedded Linux as operating system allows the development of application specific software for SBR FX, an application development kit is separately available. Powerful 32 bit microcontroller Samsung S3C4510B with CAN controller SJA1000 Abrogation of the extension/datarate restrictions of the CAN bus The CAN typical error handling mechanisms are preserved Optical fiber extensions up to 15/40 km possible (2 different device types) Adaptation to higher layer protocols (e.g. SafetyBus p, CANopen) using specific firmware
