Icons, Backgrounds, Screensaver, Firmware Update

You can update the device icons, backgrounds, screensavers, and firmware via a USB interface.

A system integrator prepares the upgrade package with the icons, backgrounds, screensaver, and firmware and uploads it to an external storage device (USB flash drive).

Make sure your USB flash drive meets the following criteria:

• Volume: Not more than 32 GB and enough space to store firmware, customized backgrounds, screensavers, icons, etc.

• File system: FAT32.

You can format the USB drive to FAT32 in your Windows File Explorer:

Click This PC > right mouse click on your USB drive > select Format... > select FAT32 in the File System drop-down menu.

To connect your USB drive to the device, you need an OTG USB cable with a micro USB port on one side and a USB 2.0 port on the other.

For using the USB interface for updates and activating micro USB port of the device, set a secure four-digit PIN code. The preset PIN code combination is 1234. USB interface becomes disabled if you set an invalid PIN code.

If you want to update your device firmware, backgrounds, screensavers, and import customized icons, proceed as follows:

1. Copy firmware and customized PNG files to the following directories of the USB drive like this:

   • Firmware: root directory

   • Background: \background

   • Screensaver: \screensaver

   • Customized icons: \icon

   The system can detect your files only if they are correctly named as follows:

   Background pictures:

   • File format: PNG

   • Size: 480 × 480 pixels

   • Name: <1.png>, <2.png>, or <3.png>

   Screen saver pictures:

   • File format: PNG

   • Size: 480 × 480 pixels

   • Name: 00.png

   Icons:

   • File format: PNG

   • Size: 58 × 58 pixels

   • Name: Refer to ETS configuration – 01_G.png (green icon nr. 01), 01_W.png (white icon nr. 01), 30_G.png (green icon nr. 30). After import, you can select them accordingly in the ETS application.

2. To avoid the update being interrupted by unwanted screen events, the following is recommended:

   • Disable the screensaver and delay time temporarily.
     

     • General settings > User interface > set Turn off screen after to “0”.

     • General settings > User interface > Screen Access > click Deactivation

   • Remove unnecessary files from the root directory of your USB drive.

3. Connect the USB drive and device with an OTG USB cable and wait for the device to detect the import package. If there is no response, check the following:

   • The device has a micro USB port activated.

   • There are no files in the root directory of the USB drive except for the firmware.

   • USB drive and the device are well connected by micro USB cable.

4. When the import package is recognized, a pop-up message appears:
   System upgrade pack detected
   Update version:
   Current version:
   Upgrade version?
   Cancel
   Confirm

5. For upgrading, click confirm > enter your PIN code.

6. If the PIN code is valid, the firmware update starts. Once done, the device reboots automatically.

7. The device automatically checks the background, screensaver, and icon files in your USB drive. Choose which folders you want to import. The system asks you about each detected folder. Click cancel or confirm.

The system starts importing the files. Once the file import is complete, the device restarts within 10 seconds.
