Loading the firmware to the switcher
To load a new version of firmware to your SW2/SW4, use
the Firmware Loader software. Your computer’s serial port
must be connected to the first three pins on the switcher’s
Remote/Auto-SW serial port. See chapter 2, “Installation,” for
information on connecting to the serial port.
1
. If you have not already done so, download the Firmware
Loader installer executable file to your computer (see
“Downloading the firmware,” earlier in this chapter).
2 . If necessary, browse to locate the Firmware Loader
executable file in your computer’s file system, and double-
click on it to open it.
3 . Follow the instructions on the Installation Wizard screens
to install the Firmware Loader on your computer. Unless
you specify otherwise, the installer program places the
Firmware Loader file, “FWLoader.exe” at
c:\Program Files\Extron\FWLoader
If the Extron and FWLoader folders do not yet exist in your
Program Files folder, the installer creates them.
4 . Access the FWLoader.exe file via your desktop Start menu
by making the following selections:
Start > All Programs > Extron Electronics > Firmware
Loader > Firmware Loader
5 . On the first screen that appears, select the RS-232 tab.
N Although the screen also has a TCP/IP tab, the
SW2/SW4 does not have a LAN port. Do not select the
TCP/IP tab.
6 . From the drop-down menus on the RS-232 screen, select
the appropriate Com port number and baud rate (the
default is 9600). (The Device selection is optional.)
7 . Click OK. The firmware selection screen appears.
8 . On the firmware selection screen, click Browse to open the
Choose Firmware File window, and locate the firmware
file that you downloaded. (By default, the firmware file is
placed at c:\Program Files\Extron\Firmware\SW-DVI-A
when downloaded from the Extron Web site.)
C The firmware file must have a .s19 extension.
Uploading any other file type could cause the
switcher to stop functioning.
