For each OS upgrade Flowbird will supply a CWT OS Upgrade Package, a zip file containing new versions of the OS files and some other files.
The operating system can be updated from a USB memory device. This requires, however, that the file UI.xaml contains a specific tag that adds the alternative Upload OS image from file in the Utilites section in the service menu.
The procedures to modify the UI.xaml file and update the operating system are described below.
The menu structure described is for a CWT Compact using the Standard Configuration. Terminals using another configuration may have another menu structure.
| 1. | Save the file nk.bin supplied by Cale in the USB-memory stick, preferably in a new folder named OS. |
| 2. | Insert the USB-memory stick into the USB connector at the back of the lowered display module. This can be done with the terminal switched ON. |
| 4. | Select Utilities in the service menu. |
| 5. | Select Upload OS image from file |
| 6. | Step to the folder \OS\. |
| 7. | Press the Go into button. |
| 8. | Step to the file nk.bin. |
| 9. | Press the Choose button. The updating process starts, but there is no indication that it is running. |
| 10. | Wait until the display returns to a previous display panel. This will take a couple of minutes. |
| 11. | With the USB memory still inserted, close the cabinet door. The terminal will issue a version ticket and then restart. |
| 12. | When the terminal is up and running again, open the cabinet door and remove the USB memory stick. |
| 13. | Close the cabinet door. A new version ticket is printed. Check the ticket to verify that the new OS-version has been successfully installed. |
