3.5 Updating the Unit’s Firmware

To upgrade the X4’s firmware, click the Advanced Setup icon at the top of the main interface page and then follow these steps.

1 You must first download the upgrade (for example, from our web site or a floppy disk). Save it under some filename.

2 Click the Firmware Update button.

3 Click Browse and select the file and upgrade’s filename. Alternatively, you can type a pathname and filename of your choosing. The upgrade file should have a .DLF extension.

4 Click Open, Upload, and then Reboot. Note: The reboot process may take up to a minute.

VERY IMPORTANT!

Do not turn off the X4 or unplug it while you are upgrading the firmware.

5 The unit’s LINK light will go off during the rebooting process. Then it will blink and finally remain on steady; the process is now complete. Note: This process may take up to a minute.

6 Close and re-open your Web browser and resume your Internet session.
