Support custom heartbeat packet, distributing socket protocol, MODBUS polling function. Support timeout reset function, timing reset function. Support remote upgrade. Add hardware watch dog, makes more stable. Supports free framing and automatic framing on the serial port, for higher forwarding efficiency.
Support websocket and realize the timing communication for serial port and web page. Support web page, serial/network AT command to conFigure parameters. Support one key (press the reload button for more than 5 seconds) to restore factory settings. Long distance communication: two serial server can transport for 150m (Test conditions: open line of sight, two WIFI serial servers self-networking, 57600 baud rate, no packet loss during transmission)
Rail-mount Serial Server: Industrial Rail-mount Support, Easy to Install, Compact Size, Cost-effective. Support Transparent Transmission Mode: Supports TCP Server / TCP Client / UDP Server / UDP Client. Serial Command Mode: The user sends data to the server according to the protocol. Send data to different servers without restarting.
Support HTTPD Client Mode: After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server. Modbus Gateway support: Support Modbus TCP and Modbus RTU interconversion mode. AT command mode: The user can query the current status of the module, or set related parameters, by sending AT commands.
Support MQTT function: Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms.
