Product Description
    This series of products using industrial redundant ring network design each device has two for the composition of the ring network fiber port through the hand-held cascade way to form a ring network topology industrial redundant ring network (FC-Ring) Designed to achieve the stability reliability and real-time nature of data transmission in harsh environments. Its working principle is the physical connection into a ring structure the work of the network signal into a chain structure once the transmission cable somewhere node break the device in a very short time automatically switch to the backup line transmission. Redundant ring network structure not only reduces the risk of data transmission but also simplifies the installation of the project reducing the cost of the project.
    This product provides: 2 Gigabit SFP Ethernet port; 4*FE+4*100base-FX; 2*RS232/422/485 serial port. 2 serial port for the independent design each serial port from the main design one is the main control node the other is from the node.
Functional Properties
◆ Industrial rail design designed for harsh and harsh industrial environments;
◆ Provide two fiber lines in the line failure can automatically switch to ensure that communication is normal.
◆ Support a variety of fiber network structure: point to point star chain ring network redundancy and can be combined for more complex network topology to support a variety of fiber network structure;
◆ Equipment to provide 4*FE 4*100base-FX 2*Gigabit optical Ethernet interface the total transmission bandwidth of the ring network for the wire speed 1000M;
◆ Switch built-in 1Mbit MP-SSRAM high-speed memory non-blocking design the largest backplane bandwidth 32GBit / S;
◆ based on FPGA + ARM design the time of self - healing loopback is shortened quickly and the "FC - Ring" redundant ring network (self - healing time <20ms) is supported.
◆ Support VLAN long packet transmission can support IEEE802.1Q protocol with the switch to use the product to support up to 10K bytes of Ethernet packets;
◆ With broadcast storm protection balance flow isolation conflict and detection errors and other functions;
◆ 10 / 100Mbps adaptive electrical port MDI / MDI-X adaptive without manual adjustment
◆ Ethernet interface with serial data with lightning protection lightning protection to GB / T17626.5 (IEC61000-4-5) short circuit current wave 10/700μs open peak output voltage 6KV standard;
◆ Provide 2 RS232 / 485/422 optional interface three data interface optional
◆ RS232 / 485/422 channel can transmit asynchronous serial data from 0-115200 baud rate;
◆ Equipment with Console (CLI) network management and WEB management platform you can online software upgrades the host side can manage the working status of each slave device;
◆ Support a wide range of AC and DC input (9V-48V) support for internal isolation redundant dual power input power support overload protection anti-reverse protection;
◆ Meet the requirements of industrial four electromagnetic compatibility;
◆ Super lightning protection function: anti-lightning anti-sensor high pressure anti-surge etc. no fan efficient cooling reduce the repair time;
◆ Anodized aluminum alloy housing IP40 protection class able to withstand the harsh environment of the test to provide rail or wall mounted;
◆ Wide temperature type: Operating temperature -40 ℃ ~ +85 ℃;
