Functional Block Diagram

Serial to WiFi and Ethernet Converter,Functional Block Diagram



RS232 to WiFi converter/RS485 to WiFi converter TMR-WR106 has passed EFT test, when there is instantaneous high current in the circuit (such as lightning, power switch, etc.), it can ensure that the device hardware is not damaged.

Power: 2KV
Ethernet interface 232 485: 2KV





Serial to WiFi and Ethernet Converter,watchdog,hardware circuit, 24 hours stable operation


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.


https Client Mode

In this mode, serial data will be submitted to the https server via https 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

RS232 to WiFi converter/RS485 to WiFi converter TMR-WR106 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.Serial port heartbeat packet notifies the serial device that TMR-WR106 is in an active state, and takes the initiative to grab the sensor data can not be initiative to push.



Socket Distribution Protocol

TMR-WR106 suppports SDP, you can add certain header in serial data. It will send the data to differetnt socket by different header. The data received from different
socket will be added different header before they are sent to serial.


Regular Restart Function

TMR-WR106 supports timing and timeout restart function, which makes the system run more stable.
