  • RS232 / RS485 Serial to WiFi Server - USR-WIFI232-630

    USR-WIFI232-630 wifi serial server is a wireless networking server, which is used for project of RS232/RS485 serial equipment to WIFI or Ethernet networking. and It has 2 channel RJ45 port.

    Feature of RS232 / RS485 Serial Wireless Servers

    • HTTP Client: serial data submitted to server by HTTP (GET/POST)
    • Websocket: support bidirectional transparent transmission between built-in web page and serial
    • DNS/DHCP: support dynamically to acquire domain and IP
    • Username/Password Verification
    • Modbus: support mutual conversion between Modbus TCP and Modbus RTU
    • TCPB Function: support 2 network links and send data to 2 targets
    • Customised MAC: users can define the MAC address by themselves
    • Built-in Webpage
    • Firmware Upgrade through Webpage
    • ID Registration: send ID package when TCP establishes connection, or each data automatically increases ID packet header
    • Virtual Serial Software (USR-VCOM) automatically connect devices
    • Baud Rate Sync: network protocol dynamically sets serial parameter
