Loading the firmware to the switcher
To load a new version of rmware to your SW2/SW4, use
the Firmware Loader software. Your computer’s serial port
must be connected to the rst 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 le to your computer (see
“Downloading the rmware,” earlier in this chapter).
2. If necessary, browse to locate the Firmware Loader
executable le in your computer’s le 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 le, “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 le via your desktop Start menu
by making the following selections:
Start > All Programs > Extron Electronics > Firmware
Loader > Firmware Loader
5. On the rst 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 rmware selection screen appears.
8. On the rmware selection screen, click Browse to open the
Choose Firmware File window, and locate the rmware
le that you downloaded. (By default, the rmware le 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.
