TMX08 IoT Wireless Device
User Manual

1 Product Introduction
This product is used to collect all sensor data from Ice Merchandiser. It can automatically provide
the location, temperature, volume and the current draw of the device, and through LTE-M
communication module the device will send data to the ice merchandiser operation platform.
2 Function
➢Location: The Ice Merchandiser operation company can check the location of the ice
merchandiser to avoid equipment missing.
➢Data Reporting: The IoT wireless device will report the collected data such as temperature,
volume and compressor current draw, then report to the backend platform, so that the
customer can monitor overall status of merchandiser.
➢Power supply alarm: If the input power supply is break, the device will automatically start
its own battery, and send alarm to backend platform to inform the situation of the power
supply is gone.
➢Over-Temp. alarm: When the temperature inside the merchandiser is over spec, alarm will
be sent to the backend platform.

3 Device Installation Guidance:
Device Installation Steps:
1) Connection the Main cable to the Device like below

2) Connection the Power Adaptor to the main cable

3) Connection the Current Draw Sensor to the main cable

4) Connection the ultrasonic/temperature sensor to the main cable

The ultrasonic/temperature sensor cable should go through the drilled hole of the
merchandiser and connect to the sensor which need to be fixed on the inner roof of the
merchandiser.

5) Connection the GPS antenna and Cellular antenna to the device.

6) Fix the bracket to the top of the merchandiser, then fasten the device with cables to the
bracket.
7) Plug the power adaptor to the power socket.
5 Function Test
After the product is installed and connected correctly, from platform side, we can read all related
data so that we can judge the overall status of the equipment is good or not.
