Basic Function

  • Modbus to Ethernet Converters USR-TCP232-410S can realize bi-directional transparent transmission between RS232/RS485 and Ethernet RS232/RS485 ports can work at same time, not affect each other.
  • Industrial Solution
    • Based on TI Cortex M4 Solution, signal processing more efficient and reliable.
    • Equipped with optimized TCP/IP protocol stack, stable and reliable, Modbus to Ethernet converters USR-TCP232-410S.
    • Can realize bi-directional transparent transmission efficiency.
    • Work Temp: -40 ~85C, Supports hardware watchdog to keep it work stable.
  • Multiple Working Modes – Modbus to Ethernet converters USR-TCP232-410S support 5 work modes: TCP Server, TCP Client, UDP Client, UDP Server and httpsD Client. Configure simply and it can realize data transmission.
    • TCP Client
    • TCP Server
    • UDP Client
    • UDP Server
    • https D Client

Characteristics Function

  • Virtual COM – Solve the problem that PC software cannot communicate with network and equipment as a serial port.
  • Identification of broken network, automatically wired – Solve the identification of dead links easily, automatic reconnection, prevent data loss due to power outages, disconnection.
  • Modbus gateway – Polling mechanism can solve the problem of sticky congestion effectively, which is caused by data concurrency.
  • Customize built-in webpage for users Web to Serial – Design built-in webpages according to project requirements and realize webpage control, web page data acquisition and other functions.


    • Electrical Fire Network Monitoring
