|Installing the FTDI driver||Follow this link to the FTDI Site for drivers: http://www.ftdichip.com/Drivers/VCP.htm
Depending on the Operating System you have, the driver needed for the Utility to communicate with the KPA500 will need to be loaded.
All Elecraft products in production use the FTDI chipset for this function. The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.
For the KPA500, if your KUSB cable has a silver sheath on the wire, it is no longer supported. Elecraft recommends that a KUSB cable be purchased for full support.
NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to firstname.lastname@example.org.
A little more detail
We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this. Beta firmware means that, while the KPA500 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status. You can always return to the last firmware you have downloaded by following the steps in the KPA500 Utility’s Help section.
To load Beta Firmware, follow the steps below:
1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the KPA500 Utility. In this way, you can revert to the last Production firmware easily.
2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:
If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on your browser to update your browser cache.
3. Right-click on the .zip file containing the beta firmware (e.g. KPA500fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.
4. Unzip the files into the beta folder.
5. Enter the path to the beta folder in KPA500 Utility → Firmware tab → "Local folder for firmware files".
6. After you have made the change in Step 5, make sure you *DO NOT* check the KPA500 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.
7. Connect the KPA500 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.
8. Review the release notes. To find them, select the "Help" pull-down menu.
9. Click "Send all firmware to KPA500." This will cause the firmware to be sent to the KPA500. You will see that the KPA500 appears to restart itself. Monitor the Activity Log until it is complete.
10. After completing a new software download to your product, please power cycle the KPA500 OFF and then back ON before using it.
11. Please report any new firmware issues to email@example.com
