Overview #
- The device operates within an input voltage range of 2.7-12Vdc.
- JST connectors are employed for power & communication ports.
- Screw connectors are utilized for the NTC1B/NTC2R sensors.
- LED status indicators provide a visual representation of the device’s operational status.

Figure 1 displays all the ports on the TMU (Temperature Monitor Unit). The NTC1B/NTC2R sensors are labeled from 1 to 4 as shown. During normal operation, the temperature reading from the sensor with the highest temperature will be shown on the GTMSUI (General Temperature Monitoring System User Interface). Users have the option to connect sensors 1 to 4 based on their specific monitoring needs or requirements.
LED Status Indicators #
Figure 2. #
LED status indicators provide a visual representation of the device’s operational status. These indicators include different colored lights, green and red for activity or communication. LED status indicators offer users a quick and easy way to monitor the device’s functioning without needing to access a screen or interface.
When the monitor is powered up, the green LED will blink five times before entering standby mode. In this state, both the green and red LEDs will remain illuminated. The monitor is now in standby mode and ready to be registered on the network. Once the monitor is successfully registered in the network by the GTCU (General Temperature Control Unit), it will commence temperature monitoring. The red LED will turn off, and the green LED will begin blinking to indicate that monitoring is in progress.
