Bundled with this package:

1) readme.txt – This file
2) VELUX KLF150 v1.0.30.EXE – The KLF150 service application
3) CP210xVCPInstaller_(...).exe – The KLF150 serial driver
4) KLF150EU_1.1.2_fwu.bin – The latest KLF150 firmware

Connect the KLF150 directly to the PC with a USB data cable. Be aware that some cables are “power only” and will not work.
After the KLF150 powers up, start the KLF150 service application. No installation is required; the application can be run from any location. For the first run, we recommend starting it directly from the unzipped package.

The service application should automatically detect the KLF150 and display its current state.
If the installed firmware is not supported by the service application, you will be required to update the firmware.

Troubleshooting:
If the KLF150 service application does not automatically connect to the KLF150, possible reasons include:
1) The KLF150 is connected through a hub or USB gateway instead of directly to the PC.
2) The USB cable is power-only.
3) Windows does not have the correct driver installed.

Missing driver:
Run the bundled serial driver and follow the on-screen instructions. This may require administrator rights.
If installed correctly, the KLF150 will appear in Device Manager under Ports as "Silicon Labs CP210......"
After installation, restart the KLF150 service application.

Updating firmware:
1) Under [SETUP], select [SOFTWARE UPDATE].
2) Select [SELECT FILE] and locate the bundled firmware file.
3) Select [UPDATE] and wait for the process to complete.
After the update, the KLF150 will restart and display its current state.
