Important:

Please ensure that you save the configuration of your network-enabled monitoring system as well as the syslog and the sensor data before updating. This firmware will restore the device to factory delivery state! Please follow the instructions very carefully. If you have any questions, please contact the support via e-mail to support@didactum.com

The firmware update of the Didactum monitoring device can be done in two ways

  • Firmware Update Tool
  • Firmware update via the web interface (from installed firmware version "2.7.1.-b1762" or later)

Please use the firmware update tool (1), if an earlier firmware than the release "2.7.1.-b1762" is installed. With the help of this tool, your monitoring unit is reset to the factory-delivery state. The firmware update via the Web Interface (2) is used to update the unit directly via the WebGUI. Please note that the firmware version "2.7.1.-b1762" (or higher) must be installed on the monitoring system.

After the driver installation you will find this driver in the device manager. This driver is mandatory for firmware update.
Fig.: After the driver installation you will find this driver in the device manager of your Windows OS. This driver is mandatory for firmware update procedure.

Installation of USB drivers for Windows Operating Systems

Please unpack the “ WinUSB.zip” file. This file contains an .exe file ( "WinUSB4NuVCOM_NUC970.exe") with the necessary USB drivers for your monitoring
unit. If necessary, you must enter the admin password of your Windows OS for the driver installation.

After a successful driver installation, you will find a new device driver called "NuVCOMDeviceClass" in the Windows system control under Device manager.

Please restart your Windows computer after sucessful driver installation.

Installation of firmware update tool
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 existing firmware including all settings will be deleted. This process can take several minutes. On green bar, the progress will be indicated. After the tool will show you information "Successful deletion", please click on "Burn".

Here the current firmware is then uploaded to your monitoring unit. The green progress bar will indicate the progress of firmware installation. After a successful update, this will be displayed in a new window.

Installation of firmware update tool

Please unpack the packed "Writer.zip" file. In the packed folder you will find the tool called "NuWriter.exe". Please start this tool.

If necessary, you must enter the admin password for your OS. Please disconnect your monitoring device from the power supply (12). Use a ballpoint pen to change the DIP switch (8) to position „Recovery". Then reconnect the power supply. Connect the device to your computer using a USB mini cable. The „NuWriter" tool will then indicate the processor type of your monitoring unit automatically. Please check if "NUC976DK62Y.ini" has been detected successfully.

Caution:

Please check if the type “SPI”is recognized correctly. "DDR Init" must be set to "NUC976DK62Y.ini". If the USB cable is not already connected to the monitoring unit, please plug it in and click on "Re-Connect". Under "Parameters", select the firmware file called "didactum-2.7.1-xxx.bin". Do not choose the file with suffix “zor”. “Pack” must be chosen as “ImageType”.

Firmware installation
Fig .: In the tab "Firmware" under "System menu" enter the path of the "didactum-x.x.x-bxxx.zor" file and click on "Upload". Please confirm the firmware update, which then starts immediately.

Firmware installation

Download the appropriate firmware release for your monitoring device from here.

After unpacking the zip file, you will find a file with the suffix ".zor", such as eg "didactum-2.7.1-b1991.zor". This firmware file can be easily installed via the web interface of your IT monitoring system.

Depending on the size of the update, the firmware update procedure can take several minutes. Please do not interrupt the power supply and network connection during the update! After the successful update, the new firmware version is displayed under "System menu".

Contrary to expectations, if the firmware update should fail, please repeat the process. In very rare cases, you must install the firmware with the firmware update tool. Then follow the instructions described in point 1.

After succesful firmware update

After succesful firmware update, please disconnect 50/100 II/100 III/500 II remote monitoring appliances from power supply. Use the ballpoint pen again to change the DIP switch from „Recovery" to „Normal“ mode. 

Then reconnect the remote monitoring device to the power supply and connect the network cable.

Your remote monitoring unit has been restored to the original factory settings with the default IP address "192.168.0.193“.
