  • Serial RS485 to WiFi Server Converter - USR-WIFI232-604-V2

    USR-WIFI232-604-V2 is used to transmit data between RS485 and WIFI TCPIP transparently. User can update the product to WIFI control without knowing the WIFI and TCPIP detail. All the converting work is done by the module. For users, the RS485 side is only as a serial device, the WIFI side is TCPIP Socket data. User can setup the work detail by simple settings which can setup via built-in web pages or RS485 port. The setup only needs do once, then it will save the setting forever.
