16 Port Serial Server | Support SSL, MQTT | WEB and SNMP Management

View : 393
Type : Serial to Ethernet Converter
Description :

The product supports 16 RS232/RS422/RS485 to 2 100M Ethernet Comb ports, meets the requirement of dual IP and dual MAC/multi-network management or network backup.


The device is an industrial din-rail serial server with IP40 protection level. It is a serial network server that enables serial devices to have networking capabilities immediately and can centrally manage scattered serial devices and hosts by the network. The product supports 16-channel RS-232/RS-422/RS-485 to 2*100M Ethernet Comb port, it meets the requirement of dual IP and dual MAC/multi-network management or network backup, and can adopt 35mm railed and wall-mounted installation methods which can meet the needs of different application sites.


The serial port server supports a variety of network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, SSH, MQTT, and other protocols. It has complete management functions and supports access control, quick configuration, online upgrade, etc. Each serial port supports 4 TCP or UDP session connections, supports Modbus TCP, TCP Server, TCP Server, TCP Client, UDP Server, UDP Client, Modbus to MQTT, and other working modes; and supports WEB access mode. In addition, the management and configuration tool based on the Windows platform is provided, and the serial device can be connected to the Internet immediately by simple settings. The interface design of the network management system is friendly, and the operation is simple and convenient, which can bring you a good user experience.


The hardware adopts fanless, low power consumption, wide temperature, and wide pressure design, and has passed strict tests in compliance with industry standards. It can adapt to industrial field environments with strict requirements for EMC. It can be widely used in PLC control and management, building automation, medical and healthcare automation, measuring instrument and environmental power monitoring system, etc.


It can be used in many embedded network control applications:

Industrial automation production

Security access control: network access control, alarm equipment, infrared detection alarm, remote card reader

Smart home equipment: smart home gateway, smart socket, smart switch

Network IO controller: industrial remote IO input, remote relay control

Building intelligence and energy monitoring

Medical monitoring equipment
