Double Serial Device RS232 RS485 RS422 Ethernet Server Modbus to MQTT lot Gateway Multi-Host Polling USR-N520 H7 Version

Description

• The USR-N520 Supports Modbus RTU Master for retrieving field site data from serial meters. After collecting data, users can convert serial data to MQTT json format data, allowing users to get field site data while save space and time.
• New Solution: New ARM core, Cortex-M7 solution, which has a main frequency up to 400MHz, compatible with TCP/lP protocol stack. lt has low latency and strong scalability, stable and reliable.
• USR-N520 compatible with TCP Client, TCP Server, UDP Client, UDP Server and HTTPD Client working modes, achieves data transparent transmission via simple configuration. Supports 2 serial ports working independently.
• Modbus Gateway: It compatible with Modbus TCP and Modbus RTU protocol mutual conversion, multi-host poling function.
• Dual Sockets: Each serial port supports connecting to two different servers at the same time. Two sockets are mutually backed up, providing higher reliability and better flexibility.

USR-N520 is 2-port serial to Ethernet converter. lt adopts Cortex-M7 solution,which has a main frequency up to 400MHz, powerful performance , fast transmission speed, and high reliability. compatible with TCP/P stack, built in hardware and sofware watchdog and a variety of keepalive mechanisms,USR-N520 keeps online all the time.
