Installation of USB drivers for Windows Operating Systems
The firmware update tool for the current generation of Didactum IT monitoring systems was tested under Microsoft Windows 7, Windows 8.1 and Windows 10. Please download the latest firmware release for your Monitoring System 50/100 II / 100 III / 500 II in Didactum`s download area .
Please do not use a virtual OS. Please unpack the packed file "WinUSB.zip".
This file contains an .exe file ("WinUSB4NuVCOM_NUC970.exe") with the necessary USB CPU drivers for the IP-based remote monitoring unit. If necessary, you have enter the admin password for the driver installation. After you installed the USB drivers, you will find a new device driver named "NuVCOMDeviceClass" under the item "device manager" in the Windows Control Panel.
After driver installation, please restart your Windows computer.
Start the firmware update tool (approx. 5 minutes duration)
Please unpack the "Writer.zip" file. In the folder you will find the firmware update tool called "NuWriter.exe". Please start this tool. If necessary, you have to enter the admin password to run this CPU tool. Disconnect your remote monitoring unit from the power supply (12). Use a ballpoint pen to change the DIP switch (8) to "Recovery" position. Then reconnect the power supply to the device. Then connect the device to your computer using a USB mini cable. The CPU tool then automatically authenticates the device type. Please check whether "NUC976DK62Y.ini" has been successfully detected.
Please verify that "Choose Type" displays "SPI". "DDR Init" must be set to "NUC976DK62Y.ini". If the USB cable has not yet been connected to the monitoring system, please plug it in and click on "Re-Connect". Under "Parameters", select the corresponding firmware file "Didactum-2.7.1-xxx.bin" (not the file with the extension .zor). The "Image Type" must be set to "Pack"!
If "SPI" and under DDR Init "NUC976DK62Y.ini" as well as the bin file have been selected correctly, please click on the button "Eraseall".
Here, the old firmware including all system settings will be deleted. This process can take several minutes. You will see a progress bar. After the tool displays "successful deletion", please click on "Burn". The new firmware (for example, "2.7.1.-b1762") is then uploaded to your IP-based remote monitoring device. The green bar indicates the progress of firmware update. The firmware tool will signal the successful microcode update.
After firmware microcode update
After the successful firmware update, disconnect the monitoring device from the power supply. Use a ballpoint pen to change the DIP switch (8) from "Recovery" to „ ormal" position again. Then reconnect the device to power supply and connect the network cable and the IP capable sensors. Your IP-based remote monitoring device has now original factory settings with default IP address "192.168.0.193".
