USR-N520
is 2-port serial to Ethernet converter. It adopts Cortex-M7 solution,which has
a main frequency up to 400MHz, powerful performance, fast transmission speed,
and high reliability. Equipped with a deeply optimized TCP/IP stack, built in
hardware and software watchdog and a variety of keepalive mechanisms,USR-N520
keeps online all the time. It supports TCP Client, TCP Server, UDP Client, UDP
Server and 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 collecting data, users can convert serial data to MQTT json
format data, allowing users to get field site data. This two-in-one design
reduces system complexity and the amount of space required in the network
topology, as well as overall installation time.
² New Solution
New ARM core, Cortex-M7 solution, equipped with deeply
optimized TCP/IP protocol stack. It has low latency and strong scalability,
stable and reliable.
² Modbus Gateway
It supports Modbus TCP and Modbus RTU protocol mutual
conversion, multi-host polling function. Industrial Grade
Design
The device conforms to industrial design standards.
Reliable EMC protection and -40~85℃ operating temperature
make it endure various complex industrial scenarios.
² Dual Sockets
