2-Port Serial to Ethernet Servers USR-N520-H7-6 with RS232/485 Interface (USR-N520-H7-6 * 1 Set)

USR-N520 is 2-port serial to Ethernet converter. It adopts Cortex-M7 solution,which has a mainfrequencyupto 400MHz, powerful performance, fast transmission speed, and high reliability. Equipped withadeeplyoptimized TCP/IP stack, built in hardware and software watchdog and a variety of keepalivemechanisms,USR-N520 keeps online all the time. It supports TCP Client, TCP Server, UDPClient, UDPServerand HTTPD Client working modes, achieves data transparent transmission via simple configuration
The USR-N520 supports Modbus RTU Master for retrieving field site data from serial meters. After collectingdata, users can convert serial data to MQTT json format data, allowing users to get field sitedata. Thistwo-in-one design reduces system complexity and the amount of space required in the network topology, aswell as overall installation time
Supports SSL/TLS encryption in TCP client, HTTP client and MQTT operation modes, supports two-way certificates authentication.
ETransfer between Modbus RTU and Modbus TCP protocol, support Modbus multi-host polling. Support up to 128 data points for data collection and Modbus address mapping.
