CAN communication router EtherCAN FX

point-to-pointdataRS232

EtherCAN 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. EtherCAN 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 EtherCAN FX, an application development kit is separately available. Safety-related applications with SafetyBUS p are supported by the version SBR FX. Powerful 32 bit microcontroller Samsung S3C4510B with CAN controller SJA1000 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 EtherCAN FX includes a CAN segment connected by a D-Sub9 male plug. The power supply of the device is achieved by plugable terminals with four contacts. For configuration purposes a RS232 interface is provided. A pair of single mode optical fibers (9 µm) are connected by LC plugs.
