can光纤路由器CAN-LWL-Router EtherCAN FX，认证测试用
Optical fibre based Ethernet/CAN router for the connection of CAN subnetworks
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 fibre extensions up to 15/40 km possible (2 different device types)
Adaptation to higher layer protocols (e.g. SafetyBus p, CANopen) using specific firmware
Rail mountable
EtherCAN FX transmits data between CAN networks using optical fibre. To achieve the connection two devices are linked back-to-back. The transmission protocol used on the optical fibre 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 15km or 40km are possible. EtherCAN FX includes a Samsung S3C4510B (ARM7 core) with 50Mhz clock and a Linux operating system. In addition, the device has 16MB SDRAM and 2MB 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.
EtherCAN FX includes a CAN segment connected by a D-Sub 9 male plug. The power supply of the device is achieved by plugable terminals with 4 contacts. For configuration purposes a RS232 interface is provided. A pair of single mode optical fibres (9µm) are connected by LC plugs
| Parameter | Minimal | Maximal | Unit |
| Storage temperature | -25 | +70 | °C |
| Operating temperature | 0 | +50 | °C |
| Supply voltage | -100 | +36 | V |
| Voltage on bus connections | -30 | +30 | V |
Any (also temporary) stress in excess of the limiting values may cause permanent damage on EtherCAN FX and other connected devices. Exposure to limiting conditions for extended periods may affect the reliability and shorten the life cycle of the device.
