Product Description

ISM518-4D-2C is a Layer 2 100M managed embedded switch module. It supports 8 100M Ethernet ports with fiber port or copper port optional, and also provides 4 TTL UART and 2 TTL CAN interfaces to expand RS232/485 serial port and CAN bus port. The switch adopts a store-and-forward mechanism and has powerful bandwidth processing capabilities to automatically troubleshoot data packet errors, reduce transmission failures, and ensure stable, reliable, and efficient data transmission. The hardware adopts low power consumption, wide temperature, modular design, compact structure and small size. It is easy to install and maintain, and the board can be flexibly made to customize the interface connection method; selected industrial-grade components, -40℃~+ 75℃ wide temperature operation, embedded installation method, can adapt to various harsh working environments, and the communication performance is stable.

 

ISM518-4D-2C supports a range of features and network protocols, such as MW-Ringv1/v2, ERPS, STP/RSTP, VLAN, LLDP, SNMPv1/v2c/v3, QoS, IGMP Snooping, WEB access control, static aggregation, port mirroring, static multicast MAC address binding, network diagnosis, relay alarm, SNTP, system log and system online upgrade, etc., which can improve the performance, reliability and security of the network and meet the needs of requirements of various complex networks. It supports multiple network working modes such as UDP, UDP Multicast, TCP Client/Server, Modbus RTU Master/Slave, Modbus ASCII Master/Slave, RealCOM_MCP/CCP/MW, Pair Connection Master/Slave, HTTPD Client, WebSocket Client, etc., to achieve serial port to Ethernet or Modbus TCP protocol conversion. And supports network working modes such as UDP, TCP Client/Server, UDP multicast, etc., to achieve CAN terminal device networking. This product meets the requirements of complex networks and harsh industrial environments through strict testing of functions, high and low temperatures, safety regulations and EMC. It can be widely used in fields such as comprehensive energy, smart cities, rail transit, intelligent transportation, smart factories, and industrial automation.

Features and Benefits
  1. Support rate limits for broadcast, multicast, and unknown unicast messages, detect broadcast and multicast packet storms, and prevent broadcast storms
  2. Support serial port and CAN terminal device networking, extending transmission distance, and achieving centralized network management
  3. Support conversion between Modbus RTU/ASCII and Modbus TCP protocols, and support Modbus RTU/ASCII Over TCP transparent transmission
  4. Support multiple sub-packaging mechanisms to convert serial port/CAN data into Ethernet data packets to meet the real-time needs of different networks
  5. Support Modbus ID mapping, mapping the real ID of the Modbus slave to a virtual ID for data communication to avoid duplication of slave IDs
  6. Support QoS quality of service, allowing voice, video and important data to be transmitted preferentially in network equipment to solve network congestion
  7. Support 802.1Q VLAN and provides Access, Trunk, and Hybrid interfaces to easily divide multiple broadcast domains and enhance network security.
  8. Support IGMP Snooping and establishes a Layer 2 multicast forwarding table to reduce the broadcast of multicast data in the network and save network resources.
  9. Support LLDP link layer discovery protocol, obtains LLDP neighbor device information, and monitors link status to facilitate topology management and fault location.
  10. Support ERPS Ethernet multi-ring protection technology, provides multi-ring networking, performs link backup, achieves rapid convergence, and improves network stability
  11. Support link static aggregation, which can increase transmission bandwidth and improve link reliability
  12. Support RSTP (Rapid Spanning Tree Protocol) compatible with STP (Spanning Tree Protocol) to eliminate network loops and enhance network reliability
  13. Support WEB control, HTTP, HTTPS protocol access control, login IP address restriction
  14. Support SNMPv1/v2c/v3 centralized management and SNMPv1/v2c/v3 TRAP information
  15. Support alarm function, including alarms for external power supply, network storm, port disconnection, ring network status, etc.
  16. Support port statistics, count different types of data frames sent and received, and monitor port traffic
  17. Support port mirroring, which can collect port inlet and outlet data for network detection and fault management.
