Updating the Firmware
Downloading the MSW 4V rs and 4SV rs Firmware
Extron periodically updates product firmware in conjunction with the release of new
software revisions. When updating any Extron software to the latest revision level, please
be sure to read the supplied release notes, or contact an Extron Application Engineer to
determine if your Extron product requires a firmware update (see the Extron Website for
contact information).
To find the latest MSW firmware, do the following:
1. Go to www.extron.com/download.
2. In the sidebar menu, click Firmware.
3. Find the MSW 4 rs series on the alphabetical list (you may need to click the “Next”
arrow).
4. Click the Download link for the product series and follow the instructions that appear
on the screen.
5. The file will be saved onto your computer. Note the folder where you saved the
firmware file.
CAUTION: Do not interrupt the firmware upload before it is 100% complete.
Interrupting the upload corrupts the firmware and the switcher will
not operate properly afterwards. If you experience problems with this
procedure, call the Extron S
