Product Description

ISM515-2D-2C is a Layer 2 100M managed embedded switch module. It supports 5 100M Ethernet ports with fiber port or copper port optional, and also provides 2 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~+ 85 wide temperature operation, embedded installation method, can adapt to various harsh working environments, and the communication performance is stable.


ISM515-2D-2C supports a range of features and network protocols, such as MW-Ringv1/v2, STP/RSTP, VLAN, QoS, port mirroring, static multicast MAC address binding, network diagnosis, alarm 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 various network transmission modes such as UDP, TCP Client, TCP Server, UDP multicast, etc., to realize networking of serial/CAN terminal devices. 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 broadcast, multicast and unknown unicast packet export and inlet rate limits
  2. Support unknown unicast, unknown multicast, known multicast and broadcast packet rate limiting to suppress network storms
  3. Support QoS quality of service, allowing voice, video and important data to be transmitted preferentially in network equipment to solve network congestion
  4. Support 802.1Q VLAN and provides Access, Trunk, and Hybrid interfaces to easily divide multiple broadcast domains and enhance network security.
  5. Support static multicast MAC address binding, reducing the broadcast of multicast data in the network and saving network resources.
  6. Support RSTP (Rapid Spanning Tree Protocol) compatible with STP (Spanning Tree Protocol) to eliminate network loops and enhance network reliability
  7. The serial/CAN support UDP or UDP multicast mode. Point-to-point, point-to-multi point or multi point-to-multi point communication can be achieved through the UDP protocol, which is fast and efficient.
  8. The serial/CAN support TCP Client/Server mode, establishing connections through the TCP protocol, providing reliable data transmission. TCP Client can establish 1 connection, and TCP Server can establish up to 4 connections.
  9. Support multiple sub-packaging mechanisms to convert serial port/CAN data into Ethernet data packets to meet the real-time needs of different networks
  10. The CAN supports normal mode, loopback mode and listening mode, which can be used for normal communication, bus testing and troubleshooting respectively.
  11. Support CAN ID filtering, allowing transmission of standard frames or extended frames within a specified ID range
  12. Support port statistics, counts different types of data frames sent and received, and monitors port traffic.
  13. Support visitors and administrators, and hierarchical management of users with different permissions
  14. Support device online restart, factory reset and system upgrade
