UPDATING THE OPERATING SYSTEM
The Linux operating system of the TXT 4.0 Controller must always be kept up to date. This provides ongoing
access to new functions, and ensures the security of the operating system.
To complete an update, the TXT 4.0 Controller must be connected to the internet via Wi-Fi. To do so, select the
appropriate SSID / Wi-Fi network in Settings / Network / Wi-Fi. Then, enter the network key and connect.
The status bar indicates whether the Controller is connected to the internet, and whether an update is available
(see the section “Menu in detail” / Status bar).
If an update is available, the newest available version is displayed (such as Release 3.1.0) in Settings / Updates
under “Online updates.” Select the newest version and press “Installation.” The installation will be completed. This
process will take several minutes. Then, the Controller must be switched off and back on again manually.
An update can also be completed via a USB stick or SD card (not included in the scope of delivery), even if the
Controller is not connected to the internet. The file required for this process and instructions are available for
download from the internet at www.fischertechnik.de/TXT40Controller
FAULTS
ELECTROMAGNETIC DISRUPTION
If the Controller is disrupted by external electromagnetic influences, it may be used as intended again after the
end of the disruption. It may be possible to briefly interrupt the power supply and restart the Controller.
