Installation of the USB Drivers for MS-Windows Operating Systems 

Please do not use a virtual Windows operating system. Please extract the compressed file “WinUSB.zip”. In this file, you will find an .exe file (“WinUSB4NuVCOM_NUC970.exe”) containing the required USB drivers for the monitoring system. You may need to enter the administrator password for the required driver installation. After successfully installing the USB drivers, you will find a new device driver called “NuVCOMDeviceClass” in the Windows Control Panel under Device Manager. After successfully installing the drivers, please restart your Windows computer.

Note:

In rare cases, the USB driver may not be recognized by the Windows operating system. In this case, please use a computer with a different CPU & chipset.

Starting the Firmware Update Tool

Please extract the compressed file “Writer.zip”. In the folder, you will find the firmware update tool called “NuWriter.exe”. Run this tool. You may need to enter your computer’s admin password to execute this tool. Disconnect your monitoring system from the power supply (12). Use the tip of a ballpoint pen to set the DIP switch (8) to the “Recovery” position. Then reconnect the power supply to the device. Next, connect the device to your computer using a USB cable. The tool will automatically identify the monitoring system.

Important:

Check that “SPI” is displayed under “Choose Type”. Under “DDR Init”, “NUC976DK62Y.ini” must be shown. If the USB cable has not yet been connected to the monitoring system, please plug it in now and click on “Re-Connect”.

Under “Parameters”, please select the appropriate firmware file “Didactum-2.7.x-xxx.bin” (do not select the file ending with .zor). The “Image Type” must be set to “Pack”!

If “SPI” and under DDR Init “NUC976DK62Y.ini” as well as the .bin file are correctly displayed in the firmware update tool, then click on the “Eraseall” button. This will irretrievably erase the old firmware including all system settings! This process may take several minutes.

A progress bar will appear. After the tool indicates that the erasure was successful, simply click on “Burn”. The new firmware (e.g., “2.7.3.-b012”) will then be uploaded to your Didactum monitoring system. The green bar indicates the progress of the firmware update. The tool will confirm when the firmware update has been successfully completed.

Important note: 

Please do not change the settings under “Image Type” in the CPU tool! Only “Pack” is allowed here! Changing this to “Data”, “Environment” or “uBoot” may damage your monitoring system!

After the Firmware Update

After the firmware update, please disconnect the IT monitoring system from the power supply. Use the tip of a ballpoint pen to set the DIP switch from “Recovery” back to “Normal”. Then reconnect the device to the power supply and connect the network cable and sensors. Your monitoring system now has the original factory settings again with the default IP address 192.168.0.193.

Important information:

In the factory default state, the “Guest” account of your Didactum monitoring system has full access / admin rights.

Please log in as “guest” (without quotation marks) and then configure the users and their permissions.
