roaming | yup - the file you downloaded is a self-extracting zip file - it should have a .exe extension on it (if your computer is setup to show file extensions)
just double-click the downloaded file, then click "Unzip". The file will unzip to the default directory (C:\Program Files\Trimble\EZ-Toolbox).
Now run EZ-Toolbox. Click the EZ-Guide Plus tab, and the 4.00 ROM file should appear in the "Select firmware file" dropdown menu. Uncheck "High speed upload". Then, if your lightbar is connected to your computer serial port with the null modem cable, and is turned OFF, click the "Proceed" button. Follow the instructions on the screen to complete the download. | |
