To change the network settings, please go to the "System settings" menu item in the German web interface. In the "Network" tab, you can customize the network settings of the monitoring appliance.
Description of network settings
In the “Network” menu of the IP‑based Didactum IT monitoring unit the following entries are displayed (firmware June 2021):

| Current IP address: | Current IP address of the device, assigned by the user (static) or via DHCP. |
| LTE IP address: | IP address from the LTE network, if the connection is established and an address has been assigned (requires 4G LTE modem). |
| Hostname: | Hostname of the unit (e.g. “Didactum”). Important: Do not use spaces, dots, colons, commas, or semicolons! |
| IP address: | IP address of the monitoring unit. |
| Subnet mask: | Subnet mask of the unit (e.g. 255.255.255.0). |
| Gateway: | Default gateway address (e.g. 192.168.0.1). |
| Primary DNS: | Primary DNS (e.g. 192.168.0.1). |

Determining the current network settings
To determine the current IP address of your Didactum monitoring unit, please connect an empty USB flash drive to the unit's USB port. If your unit is equipped with a mini USB port, please use the included USB adapter cable. Your Didactum monitoring system will automatically write an information file containing the current network settings to the USB flash drive. Once the LED on your USB flash drive goes out, carefully disconnect the drive from the monitoring unit. Then, insert the USB flash drive into your PC or laptop and open the information file with your operating system's text editor. The information file contains the following important information about your Didactum monitoring system:
Automatic backup of the monitoring system to USB stick
Starting with the Didactum firmware update of December 2021, when a USB stick is installed on the Didactum Monitoring System, the device's current configuration is automatically saved to that stick. This provides users with a simple way to automatically back up the configuration of their measuring and monitoring device to an external storage device.
The automatic backup file for the monitoring system is saved in a directory on the USB stick. This directory name consists of the device type name (e.g., Didactum 500 II) and the value of the "Network" => "Hostname" field. If the user has not assigned a device name to their IP thermometer or monitoring system (the default is "Hostname" without quotation marks), the device's current IP address is used automatically. This directory can then be named, for example, "Didactum 500-II-192.168.0.193" (without quotation marks). The Didactum Monitoring System creates further subfolders within this folder for the backup files. The backup files are named according to the date and time they were created, for example, "2021.12.01_11-59-12.zor".
Note: Please be aware that the automatic backup function is only available for current monitoring systems via free firmware updates. The monitoring devices that have been discontinued for some time, such as the Didactum Monitoring System 100 (1st Gen.), 100 II, or 500 (1st Gen.), do not offer this automatic backup function to a USB drive.
