Updating the firmware

The firmware upgrade utility provides a way to replace the firmware that is coded on the switcher’s control board without taking the switcher out of service.

The MAV switcher product line has two different hardware configurations. The two configurations operate and function identically, but their firmware is mutually incompatible. Ensure that you identify and download the correct firmware set (version 1.xx or 2.xx) for your switcher or the switcher will not operate after the firmware update. Version 1.xx firmware files have the file extension “.HEX”. Version 2.xx firmware files have the file extension “.s19”. See steps 1 and 2, below, to identify which firmware to retrieve from the Extron web site: www.extron.com.

Upgrading the firmware does not overwrite the current configuration, presets, or the audio settings.

Update the switcher firmware as follows:

1.	Start the Matrix Switchers Control Program and connect to the MAV switcher.
	See “Using the software”, steps 1 through 3, starting on page 4-13.
2.	Click Help and read the firmware version. Figure 4-11 shows a sample read of
	the firmware version. The most significant digit of the firmware version
	listed (such as “1” in figure 4-11) identifies the firmware set.

3. Visit the Extron web site (www.extron.com) select the MAV switcher product category, and determine the latest firmware that is in the proper firmware set.

•Firmware in the version 1.xx set can be replaced only by other version 1.xx firmware, with the file extension “.HEX”.

•Firmware in the version 2.xx set can be replaced only by other version 2.xx firmware, with the file extension “.s19”.

•The higher the version number within a firmware set, the more recent the firmware. Choose the latest version.

Select the appropriate firmware file to download and copy it to your computer. Note the folder to which you save the firmware file.
