Description :

This serial server module can enable serial devices to have networking capability and manage scattered serial devices and hosts through the network.

Overview

This industrial serial server module can enable serial devices to have networking capability immediately, and can centrally manage scattered serial devices and hosts through the network. This product supports 1 channel of TTL to 1 channel of 100M Ethernet, can be connected with RS232/422/485 interface, and the interface type can be set on the WEB interface.

The serial port server supports a variety of network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, and SNMP protocols; it has complete management functions, supports access control, quick configuration, online upgrade, etc.; each serial port supports 4 channels of TCP Or UDP session connection, support Modbus TCP, TCP Server, TCP Client, UDP Server, UDP Client, and other working modes; support WEB access mode. In addition, the management and configuration tool based on the Windows platform provided can guide users to manage and configure the device step by step, and realize the immediate networking of serial devices through 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 has passed strict tests in line with industry standards, and can adapt to the industrial field environment with strict requirements on EMC, and can be used in many embedded network control application products;
