Updating firmware
If the need arises, you can replace the MLS's firmware without opening the unit or
changing firmware chips. Follow the directions below.
This procedure must be performed using a PC on which the MediaLink Control
Software (version 2.1 or higher for MLS 304MA, MLS 406, or MLS 406MA; version
2.4 or higher for MLS 304SA and MLS 406SA) has been installed. The PC's RS-232
port must be directly cabled to the MLS's RS-232/MLC/IR port.

In the MediaLink Control Program, select File, then select Save Configuration
as... .
Save the file as (filename).MLK. An unlimited number of configuration files
can be saved as long as each file has a unique file name ending in .MLK.
To retrieve the configuration from within the MediaLink Control Program,
select File, then select Restore Configuration from... .
Follow the on-screen directions. A set of all the switcher and audio
adjustment settings is downloaded into the MLS.
Do not attempt to upload firmware if a MediaLink Controller (MLC) or
other control system is connected to the MLS switcher. The RS‑232 cable
from the PC must be connected directly to the MLS.
Each time you replace existing firmware, the switcher will be reset to the
factory default settings.
Visit the Extron Web site (www.extron.com) to find the appropriate
firmware file for the model of switcher (MLS 304MA, MLS 304SA, MLS 406,
MLS 406MA, or MLS 406SA) you want to update. Save the new firmware file,
and write down the filename and location for later use.
Connect a cable between the RS-232/MLC/IR port of the MLS and the serial
(RS-232) port of the PC (see Control connection on pages 2-7 and 2-8), and
power on the MLS.
Start the MediaLink Control program (see Using the control program on
page 4-8).
