Loading the firmware to the switcher
To load a new version of rmware to your SW4 3G SD-HDI, use
the Extron Firmware Loader software. Your computer’s serial
port must be connected to the switcher’s RS-232 serial port.
See “Rear Panel Connections,” in chapter 2, “Installation and
Operation,” 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
