IEM618-4D-2C is 8-port 100M layer 2 managed embedded industrial Ethernet switch module with 4 serial ports and 2 CAN ports featuring high integration level, small size, rich functions, easy and convenient usage. This series have 3 types of products. It provides 4 serial ports, 2 CAN ports, and 8 100M ports which could be configured to fiber port or copper port as needed. It also adopts embedded mounting that user can custom the specification of PCB motherboard and freely choose Ethernet interface type through module pin to meet the requirements of different scenes.

Network management system supports various network protocols and industrial standards, such as STP/RSTP, 802.1Q VLAN, QoS, IGMP Static Multicast, Port Trunking, Port Mirroring, etc. It also possesses complete management functions, including Port Configuration, Port Statistics, Access Control, Network Diagnosis, Rapid Configuration, Online Upgrading and so on. It has integrated functions of serial port server and CAN server. Each serial port and CAN port support 4 TCP or UDP session connections and multiple operating modes including TCP Server, TCP Client and UDP, etc. CLI, WEB, Telnet, SNMP and other access methods are also supported. The network management system can provide users with good experience with friendly design of network management system interface, simple and convenient operation.

Hardware adopts fanless, low power consumption, wide temperature design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in smart grid, railway transportation, smart city, safe city, new energy, aerospace, intelligent manufacturing, military project and other industrial fields.


Features and Benefits


 SNMPv1/v2c is used for network management of various levels

 Port mirroring can conduct data analysis and monitoring, which is convenient for online debugging

 QoS supports real-time traffic classification and priority setting

 File management is convenient for rapid configuration and online upgrade of the device

 Bandwidth management can reasonably distribute network bandwidth, preventing unpredictable network status

 Port statistics can be used for the port real time traffic statistics

 User password can conduct user hierarchical management to improve the device administrative security

 Relay alarm is convenient for troubleshooting of construction site

 Storm suppression can restrain broadcast, unknown multicast and unknown unicast

 VLAN can simplify the network planning

 Port trunking can increase network bandwidth and the reliability of network connection to achieve optimal bandwidth utilization

 IGMP-Snooping and static multicast can be used for filtering multicast traffic to save the network bandwidth

 SW-Ring and STP/RSTP can achieve network redundancy, preventing network storm

 Supports multiple serial port operating modes: TCP Server, TCP Client, UDP, TCP auto, Realcom, advanced TCP Server and advanced UDP

 Supports multiple CAN port operating modes: TCP Server, TCP Client, UDP, TCP auto, Realcom, advanced TCP Server and advanced UDP
