Serial to Ethernet Converter, Modbus RTU to TCP

Industrial Serial RS232 RS485 to Ethernet Converter

  • RS232/RS485 ports can work simultaneously
  • Modbus RTU to Modbus TCP, Modbus Polling
  • Flow Control: CTS/RTS, XON/XOFF

Industrial Solution

Based on TI Cortex M4 Solution, signal processing more efficient and reliable.
Equipped with optimized TCP/IP protocol stack, stable and reliable, which can realize bi-directional transparent transmission efficiency.
Work Temp: -40 ~85C, Supports hardware watchdog to keep it work stable.

Multiple Working Modes

USR-TCP232-410s supports 5 work modes: TCP Server, TCP Client, UDP Client, UDP Server and HTTPD Client.
Configure simply and it can realize data transmission.
