Work Mode
Transparent Transmission Mode
In this mode, all transmitted/received data is not parsed between the serial port and the WiFi interface. It minimizes the complexity of user usage.
HTTP Client Mode
In this mode, serial data will be submitted to the HTTP server via HTTP GET/POST/PUT requesting method.
AT Command Mode
In this mode, user can query/set parameters via serial AT commands or network AT commands.
Special Features
Modbus Polling Mode
In this mode, it supports Modbus TCP and Modbus RTU mutual conversion.
Heartbeat Packet Function
USR-W610 supports network heartbeat packet and serial heartbeat packet. The network heartbeat packet notifies the server that it is in an active state, and it maintains the normal connection with the server by continuously sending the heartbeat packet.
