4. Navigate to the folder where you saved the firmware upgrade file. Select the file.

NEnsure that the firmware upgrade is for the MVX Series VGA matrix switcher.

NValid firmware files must have the file extension “.S19”. Any other file extension is not a firmware upgrade.

5. Click the Open button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window (figure 4-12). The firmware upload to the switcher may take several minutes.

Figure 4-12 — Firmware Loader status indicator bar, switcher reset, and firmware update

Once the status bar has progressed fully from left to right across the indicator window, the firmware loader utility automatically resets the switcher (figure 4-10).

NIf the firmware loader utility exits before the status bar has progressed completely across the indicator window, try using a control cable with only pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or cutting wires.

NIf the firmware loader utility exits before the status bar has progressed completely across the indicator window, the firmware may be corrupted and may no longer respond to the Matrix Switchers Control Program. In this condition, the firmware upload can be accomplished only by using the SIS commands. See “Loading firmware using an SIS command” on page 4-11.

6. When prompted, confirm that the firmware version displayed in the firmware loader is correct. Click Ok in the Firmware Update prompt window to exit the firmware loader utility.
