PRELIMINARY
Updating the Main Firmware
Most fi rmware upgrade tools (except Extron Firmware Loader) require the PC and
the controller to both be connected to an Ethernet network. Firmware Loader offers
the option to use either an IP or an RS-232 connection for the fi rmware upgrade.
The instructions for each method of updating the MLC’s fi rmware assume you
have installed the appropriate software on your PC fi rst.
N
Because the MLC must be reset after a fi rmware update, the existing
confi guration will be erased. You should save the existing confi guration to
a fi le (see chapter 4) before replacing the fi rmware. If the fi le is saved, the
confi guration can be restored to the MLC later using Global Confi gurator.
N
Check the Extron Web site (www.extron.com) for fi rmware-related documents,
instructions, patch fi les, and new fi rmware fi les before loading new fi rmware into
the controller. We recommend that you read the fi rmware release notes (available
from www.extron.com) before beginning the fi rmware update.
Locating and downloading the fi rmware
1. Visit the Extron Web site (www.extron.com) to fi nd the latest, appropriate
fi rmware fi le (MLC 226 IP) you want to update.
2. Download the executable installer fi le (*.exe) from the Web site and run the
installer program. The program automatically stores the fi rmware fi le on
the PC in C:\Program Files\Extron\Firmware\MLC_226_IP\xx (a folder
specifi c to that version).
3. Write down the fi rmware fi lename and location for later use. The fi lename
ends in .s19 such as MLC226IPvxxx.s19 where xxx is the version number
(x.xx) or MLC_226_IP_yy_yyyy_yy_Vx_xx.S19 where Vx_xx indicates the
version number (x.xx).
N
The fi rmware update fi le must have a fi lename extension of .s19. If the fi le does
not have that extension, it will not work properly.
Updating fi rmware via the MLC’s embedded Web page
Firmware uploads may be performed via a Web browser and the MLC’s internal
Web page. This method allows you to update one MLC at a time via an IP
connection.
1. Download the fi rmware fi le.
2. Launch a Web browser (Microsoft Internet Explorer or Netscape Navigator)
on the connected PC and type the controller’s IP address in the address area.
3. If a password was previously set for
the MLC, an Enter Network Password
or Connect to... dialog box appears.
Type the controller’s IP address or text
of your choice in the User Name area,
type in the administrator password in
the Password area, and click OK. The
MLC’s default Web page appears.
N
Passwords must contain 4 to 12
alphanumeric characters. Symbols
and spaces are not allowed, and the
passwords are case-sensitive.
