To upgrade the OS of your XTOP device from V3.1 or V2.4 to V4.8, please follow the steps below:

Run XDesignerPlus V4.8 and select the [Transfer] – [OS Upgrade] menu.

Note 1: OS upgrades can only be performed via USB cable. If you use the [Transfer – Run Transmitter – Transfer OS and Font] menu instead of the OS Upgrade menu, you can upgrade using a serial or Ethernet cable. Please refer to the attached file for details.

Note 2: Upgrading the OS will delete all project files from the XTOP device. If you need to keep your project files, use XDesignerPlus V2.6 to upload and back them up before proceeding.

The OS upgrade process will sequentially transfer the Boot, Font, and OS files. After the Boot file is transferred, the XTOP device will automatically reset, and then the Font and OS files will be transferred in order.

If the upgrade is interrupted and the Font or OS files are not transferred correctly, the screen will remain black and display [Boot Mode], indicating only the Boot file has been transferred. In this case, simply run the [OS Upgrade] menu again to complete the upgrade.

Once the upgrade is complete, the device will enter touch calibration mode. Please follow the on-screen instructions to calibrate the touch panel accurately.

Tip: If the Font file was not transferred properly, text on the screen may appear as black squares.
