is a combination of 3 different software programs intended to configure and monitor Sentera products or to update the firmware. and can be used to update the firmware of your Sentera device. The
software allows you to configure and monitor your Sentera device.
Sentera devices exchange information via a network, called Modbus RTU. The parameters of the device can be adjusted via Modbus RTU. To facilitate the configuration and monitoring of Sentera devices, we have developed the free software suite 3SM Center which can be downloaded from Sentera’s website.
Just download the ‘3SM Center’ software suite via the website and start the ‘3S Modbus’ software. Via the USB converter (
CNVT-USB-RS485 ) the software will immediately recognise and visualise the connected Sentera product(s).
To connect a Sentera device to the computer, you need Sentera’s self-powered Modbus RTU to USB converter CNVT-USB-RS485 , which converts Modbus RTU communication to serial information on a USB virtual COM port.
How to connect a device to your computer using the CNVT-USB-RS485 converter:
1. Before you start using the CNVT-USB-RS485 converter, you need to download the free 3SM Center application from Sentera’s website and install it on your computer.
2. Connect the Modbus RTU A signal of the Sentera device(s) to the A terminal of CNVT-USB-RS485.
3. Connect the Modbus RTU /B signal of the Sentera device(s) to the /B terminal of CNVT-USB-RS485.
4. The GND terminal should NOT be used! Connecting equipment with a GND that is not common with your computer’s GND will damage your USB port.
5. Therefore it is highly recommended that you do NOT use the GND terminal.
6. Plug the converter into the USB port of your computer. It will be recognised and installed automatically once the connections are complete
Connect the Modbus device(s) which will be monitored and / or configured to the power supply network.
Start the 3SM Center Software Suite and click on the 3SModbus application button . Once you start the application, the computer will scan and automatically recognize the connected device(s).
Click the product and configure the parameters. Define set points, adjust ranges, change working modes, load and save parameters and get alerts where measurements exceed the range you set up.
To stop searching for connected devices either click on the button or press the space bar, otherwise the software will process until all connected devices have been recognised (a total of 247 possible). Once the device is recognised and the processing is complete, you can right-click on the icon of the device to check its current status.
Zoom in on your parameters by consulting the overview of live measurements. Here, you can also adjust the set points and ranges to optimise your comfort and air quality.
For detailed monitoring and configuration purposes, you should double-click on the icon of the relevant device and thus enter its parameters and settings. Every device featuring Modbus RTU communication has two types of registers:
Input registersThe input registers are read-only. They are used for monitoring purposes, i.e. indicate the current device status and the user cannot modify them. However, you can select the list of parameters you want to be displayed in the initial screen for fast right-click viewing via the button on the right of the input registers menu.
Holding registersThe holding registers are read / write registers. You can modify the device setting via the set button . The registers that are read-only do not have the set button, they just display the unmodifiable device parameters and are intended for information purposes only.
User interfaceTable view: The default display setting is the complete list of Modbus registers as displayed . This is the so called “Table view” and contains the complete monitoring and configuration data of a device. However, you can change this view to the basic parameters only i.e. the ones most important to the user via clicking on the button in the top right corner.
