1. Inleiding en oorview
The SMARTGEN CMM366A-ET Cloud Monitoring Communication Module is an Ethernet communication protocol switch module designed to connect gensets (with SCI) to the internet. After logging into a cloud server, the module receives the corresponding genset controller communication protocol. It acquires genset data via RS485, USB, LINK, or RS232 ports and transmits this data to the cloud server via wired Ethernet. This enables real-time monitoring of running status and access to historical records through mobile applications (iOS or Android) and PC terminal devices.
Beyond genset monitoring, the CMM366A-ET module also supports digital alarm input/output signals, allowing for monitoring of generator room access, theft prevention, and fire detection facilities.

5.2 Basiese werking
Once the CMM366A-ET module is correctly installed and powered, it will automatically attempt to establish a connection with the configured cloud server via the Ethernet network. The status of this connection and other communication links can be observed through the front panel LED indicators.
- Monitering: Real-time data and operational status of the genset can be monitored remotely using the dedicated mobile application (iOS or Android) or through a PC terminal connected to the cloud server.
- Parameter aanpassing: If necessary, module parameters can be adjusted by connecting a PC to the USB port and using the appropriate PC software.
- Alarmhantering: The module will immediately upload alarm data to the server upon detection of an alarm condition from connected digital inputs or the genset controller.
6. Onderhoud
The CMM366A-ET module is designed for reliable operation with minimal maintenance. To ensure optimal performance and longevity:
- Hou die module skoon en vry van stof en puin. Gebruik 'n sagte, droë lap vir skoonmaak.
- Verseker voldoende ventilasie rondom die module om oorverhitting te voorkom.
- Periodically inspect all cable connections (power, communication, Ethernet) to ensure they are secure and free from damage.
- Avoid exposing the module to extreme temperatures or humidity outside its specified operating conditions.
- There are no user-serviceable parts inside the module. Do not attempt to open or repair the device yourself.
7. Probleemoplossing
If you encounter issues with your CMM366A-ET module, refer to the following troubleshooting guide:
- No Power / All Indicators Off:
Check the DC power supply (8~35V) connected to terminals B- and B+. Ensure the power source is active and the wiring is correct. Verify any inline fuses (3A recommended for B+). - Ethernet Communication Issues (ETHERNET LED off or blinking):
Verify the Ethernet cable connection to both the module and the router. Ensure the router is powered on and has an active internet connection. Check network settings and ensure the module is correctly configured to access the cloud server. If the ETHERNET LED is off, it indicates an unsuccessful login to the server. - Genset Communication Issues (RS485, USB, LINK, RS232 LEDs off or blinking):
Check the physical connections between the CMM366A-ET module and the genset controller for the respective communication port. Ensure the genset controller is powered and functioning correctly. If an LED is off, the corresponding port might be disabled or not communicating. - Alarm Indication (Red ALARM LED is lit):
This indicates a common alarm condition. Check the connected auxiliary digital input ports for external alarm signals. Refer to your genset controller's manual for specific alarm codes or conditions. - Module Unresponsive / Unexpected Behavior:
You can perform a reset to factory default parameters. Press and hold the Lamp test/Reset button for 10 seconds. All LEDs will blink three times to confirm the reset. WAARSKUWING: After a factory reset, all parameters will revert to their default settings and must be re-configured using PC software. Proceed with caution.
