Updated firmware releases, as well as plugins and templates for the Didactum monitoring systems, can be found in the Didactum Knowledge Base didactum-security.com/en.
In the German-language web interface of the monitoring system, go to the menu item (left side) "General Statistics".
Here, under the entry "About the Monitoring System", you will see the device type and the installed firmware version.
Directly after the firmware version, you will see the installed kernel of the hardened Linux operating system.
See here a screenshot of a Didactum 500 II monitoring system:
First, load the file named "firmware-kernel.zor" onto your IT monitoring device (System Menu => Firmware => Load File). After restarting the device (please clear your web browser's cache), then install the Didactum firmware file named "firmware.zor". Again, please clear the cache before accessing this file.
A so-called "downgrade" of the firmware and the installed kernel is easily possible for Didactum brand LAN-based measuring and monitoring devices. Please use the CPU tool for this.
Should the firmware update fail unexpectedly, please check the following:
- Were the instructions followed correctly?
- Is a network connection available?
- Has the browser cache been cleared?
If the firmware update failed, you can reinstall the firmware of your smart monitoring unit using the CPU Tool.
ach firmware update includes German-language instructions in PDF format. Please also refer to the "Readme.txt" file. Detailed information about firmware is also available here on the Technology Portal for Infrastructure Security Technology. There are generally three ways to update the firmware of your SNMP monitoring hardware:
- via the German-language web interface
- via a USB stick
- using the CPU tool under Windows
Simply put, firmware is software that is permanently stored in your SNMP monitoring appliance. The firmware essentially establishes the connection between the monitoring hardware and the operating system. The firmware of Didactum devices resides in flash memory and can be updated at the user's request. Didactum provides so-called "firmware updates" for current models at regular/irregular intervals, which can be requested free of charge from support.
The firmware pre-installed in your SNMP-compatible measurement and monitoring system can be updated upon request. Of course, there is no obligation to update the firmware. Updates typically serve to enhance functionality. For example, a new dashboard function was introduced in the November 2020 firmware update.
Original accessories and spare parts can be found in the Didactum online shop for security technology.
Please ensure that you have cleared your web browser's cache before accessing the measurement and monitoring system again. After clearing the cache and accessing the web interface again, the new firmware should now be displayed under "General Statistics" => "About the Monitoring System".
he backup file named "settings.zor" will be reloaded under "System Menu" => "Firmware" => "Load Source". Please note that this process may take up to 60 seconds. Before accessing the Smart Building Monitoring System again, be sure to clear your web browser's cache.
Don't worry. Simply use the CPU tool in MS-Windows to reprogram the alarm system. Instructions (PDF file) are included in the firmware package.
Request the latest firmware for your monitoring system from support. The CPU Tool allows you to reset the system to its original factory settings under Windows 10. German instructions are included in the firmware package.
IMPORTANT EDITOR'S NOTE: All user information, device settings, and measurement data stored in the data logger will be permanently deleted when using the CPU Tool. Therefore, we recommend exporting the measurement data and current device configuration beforehand ("System Menu" => "Firmware" => "Export" => "Export Current Settings").
Upload the "firmware-kernel.zor" file from the latest firmware release to your SNMP monitoring system. The screenshot provides further information.
As described in detail in the readme.txt file of the new firmware, this release requires an update to the operating system kernel of the Didactum alarm system. After the kernel update, your smart alarm management system will function as usual.
All information on this topic can be found in the readme file of the respective microcode firmware update.
You can find the latest information about new firmware and kernel updates for Didactum surveillance products, for example, in our popular security blog. You can also find the information you need on social media (Facebook, Twitter, etc.). The relevant links are located at the bottom right under "Follow us!". Alternatively, you can use our contact form here on the technology portal.
Please note that support for the 100 II (second generation) measurement and monitoring system ended some time ago. The latest firmware releases and kernel updates (from December 2019 onwards) do NOT support this discontinued product.
After a failed firmware update in Windows, please disconnect the power supply to your remote monitoring system. Restart your Windows operating system. After reloading the CPU Firmware Tool, please reconnect the power supply to the unit. The tool should now recognize your system correctly.
All current Didactum measurement and monitoring systems can be updated as follows:
Method: Firmware Update via the Interface
To do this, download the firmware file named "firmware.zor" to your monitoring system. For monitoring systems with a very old firmware and Linux kernel installed, proceed as follows:
Method: Firmware Update via USB Stick
Copy the new firmware to an empty USB stick and connect it to your monitoring system. The system will then start the update automatically. If your system has an old Linux kernel (pre-September 2019), the kernel must also be updated.
Method: Complete Refresh of the Monitoring Unit with the CPU Tool
To do this, install the USB drivers and the CPU Tool on a Windows 10 computer. Use this utility to install the current firmware and the latest update of the hardened Linux kernel.
Please note that updating the Didactum firmware can take up to 5 minutes. Please clear your browser's cache and then re-access your web thermometer's IP address. The login window should then appear as usual.
Simply log in to your device via a web browser. Go to the "General Statistics" menu item. The "About System" entry will display your device type and the installed firmware version.
To reset your mains-powered environmental monitoring system to its factory settings, simply set the DIP switch to the Recovery position for 15 seconds. All settings will be permanently deleted. After 15 seconds, please return the DIP switch to the Normal position. The monitoring system will then be accessible at the default IP address "192.168.0.193". The login is "guest" / "guest". You can then restore your configuration backup. Alternatively, you can use the CPU tool included in the firmware file to reinstall your Didactum environmental monitoring system.
Firmware updates are being provided for the Didactum IT monitoring systems.
In rare cases, problems may occur after a firmware update. This can happen when a very old firmware with an outdated kernel is updated.
Each firmware file of your Didactum IT monitoring system contains a compressed file with the corresponding recovery tools. These tools are used to restore your Didactum monitoring system.
Here is a brief overview of the recovery tools provided by the manufacturer Didactum:
File "factory-settings.zor" - This file resets your monitoring system to its factory settings.
By default, the network settings are "192.168.0.193" and the gateway is "192.168.0.1". The factory username is "guest" / password "guest" (without quotation marks).
Caution: All settings, including those of the sensors and potential-free inputs, will be reset to factory defaults!
File "network-settings.zor" - This file resets the network settings to factory defaults.
By default, the IP address is "192.168.0.193" and the gateway is "192.168.0.1".
File "resetuser.zor" - Use this file to reset the users of your Didactum monitoring system. If you have forgotten your password, please use this tool.
By default, the username is "guest" and the password is "guest" (note: lowercase without quotation marks).
Recovery instructions for your Didactum monitoring system:
Please use an empty USB flash drive (FAT format). Rename the required tool to "firmware.zor" (without quotation marks).
Example:
You want to reset the user settings because you have lost the password for your IT monitoring system.
Therefore, rename the file "resetuser.zor" to "firmware.zor" and simply copy it to the empty USB flash drive.
Next, insert the USB dongle into the corresponding USB port on the Didactum monitoring system and briefly disconnect the power supply.
After restarting, please remove the USB dongle.
Important:
Please clear your web browser's cache before accessing the networked monitoring system again as usual!
You did not restart your measuring and monitoring device after the firmware update. Under "System Menu," you will find the option "Restart the system." Please click on this and initiate the unit's restart. Please close your browser and clear its cache. After a few seconds, you can log in again. The onboard temperature sensor will now display the correct reading.
The 400 and 500 II monitoring systems are equipped with an identical mainboard. Didactum's hardware engineers therefore opted for a joint firmware release for both systems. Compared to the 400 model, the 500 II monitoring system can be equipped with an expansion board. This board provides eight additional inputs for dry contacts, two additional bistable relays, and an additional connection for a backup power supply. The 400 model cannot be equipped with this expansion board.
If desired, you can also install the firmware file and kernel update on your monitoring and control system via USB stick.
As of December 2020, the firmware version “didactum-2.8.3 b127” is the latest release for the smart monitoring systems of the model series 50 / 100 III / 100IV (DC) / 200 / 300 / 400 / 500 II (DC).
A specially adapted firmware microcode update is available for the high-end monitoring systems 600 (DC) and 700 (DC). You can request this free of charge from support.
EOL
If you do not have a PC or laptop with a Windows operating system, please install Windows 10 via Boot Camp or in a virtual machine. You can also install Windows on a USB flash drive and then boot from it. Simply Google "installing Windows on a USB flash drive." Alternatively, you can send your monitoring system to Didactum in Münster (Westphalia).
The kernel is the hardened Linux operating system of your rack monitoring system. The date display allows you to easily see whether the installed operating system is up to date. Please note that a firmware update via the rack monitoring system's web interface does not update the kernel. This is done using the Didactum CPU Tool. Detailed instructions are included with every Didactum firmware file and can be found in the German-language user manual.
Please ensure the power supply is switched on for the firmware update. Otherwise, the CPU tool will not recognize the IT monitoring unit.
The firmware update tool can be run in a Windows 10 Pro virtual machine within Parallels Desktop 15 for Mac. This allows you to easily update the firmware of your monitoring system. Follow the instructions.
The firmware installed on your Didactum devices is from 2017. This release is too old to be updated directly via the web interface. Please follow the instructions and install the latest firmware using the CPU tool on Windows. Afterwards, the server room monitoring devices will function as expected.
Request the final firmware "Didactum FW 2.7.3b805" dated January 4, 2019, for your data logger from our support team. If you would like to trade in your old data logger, please ask Didactum sales representatives about the trade-in program. This program also applies to products from other manufacturers.
Support for the first generation of IT monitoring and network surveillance devices from 2012-2016 has ended. The final firmware, "Didactum FW 2.6.3b588," was released on September 30, 2016. Didactum offers trade-ins of qualified devices. This trade-in program also applies to products from other manufacturers. Simply contact our expert sales team.
Didactum manufactures so-called OEM devices for IT rack manufacturers. These cabinet monitoring systems and sensors are sold with the logo and in the name of the respective supplier. You can install the Didactum firmware on the device at your own risk. Unless otherwise stated in your operating manual, Didactum does not provide support for these OEM products.
Our programmers have successfully tested the USB driver with various PCs and notebooks from different manufacturers. The operating system used is Windows 10 Professional 64-bit. If your PC does not recognize the USB driver, please use a computer with an Intel chipset for the firmware update. After installing the drivers and restarting the operating system, your computer should then successfully recognize the required USB driver.
