Using the Smart Sensor Simulator 2 Interface Application

Downloading and Installing

The SSS2 Interface App is written for Windows 7 and 10. It uses a serial over USB connection to interface with the SSS2 unit.

You can download the latest version of the Interface App from the Smart Sensor Simulator 2 product page.

Once downloaded, you can run the executable to install it. Some computers will not recognize the application and ask you to block it. If this happens, you may need to over ride those settings. For example, on Windows 10 with the Windows Defender, a blue box may come up saying “Windows protected your PC.” If this happens, then press on the link that says More info. From there you can press Run Anyway.

The install process will install the Application and its support files. It will also create a new directory in your documents called SSS2. This new directory will contain all the SSS2 settings files. Finally, the virtual serial driver will be installed. On Windows 10, this step is skipped because the drivers are native to the operating system.

Plugging in the SSS2

A power source must be plugged into the SSS2 using the a +12V supply. The internal USB power is not connected to the microprocessor inside the SSS2. The order of plugging in the USB and Power for the SSS2 does not matter. However, if there are issues with the serial connection, it is best to cycle power to the SSS2 instead of unplugging and replugging in the USB cable.

The order of opening the SSS2 Interface App and plugging in the USB does not matter. The SSS2 Interface app is programmed to detect the last SSS2 it was plugged into. If the USB connection is present, then it will automatically connect.

Successful connection between the SSS2 and the Interface App is indicated by seeing the FIRMWARE version in the upper right hand entry box shortly after connection. If the USB/Serial Monitor box is red, then there is no communication between the App and the SSS2.

To select a COM port, select the menu item in the Connection menu. The dialog box to connect to the SSS2 automatically refreshes with possible COM ports that would have the SSS2 attached. Usually, the highest number COM port is the correct one, which is selected by default. However, you can select other com ports. If the refresh takes place, which is every 4 seconds or so, then the select COM port will be changed back to the default. If this happens, try selecting the desired port again and press OK before the refresh takes place. You can tell if the SSS2 is connected to the COM port in the dialog box if you unplug the USB cable and the COM port number goes away. You may have to cycle power on the SSS2 to reset it and clear the red box.
