Loading the firmware to the SW USB using the Firmware Loader

To load a new version of firmware from your computer to your SW USB using the Extron Firmware Loader software, your computer’s serial port must be connected to the switcher’s RS-232 serial port. See “Rear Panel Features,” in chapter 2, “Installation,” for information on connecting to the serial port.

1. If you have not already done so, download and install the Firmware Loader executable installer file to your computer (see “Downloading and installing the Firmware Loader,” earlier in this chapter).

2. If necessary, download the latest SW USB firmware version and install it on your computer (see “Downloading and installing the firmware,” on the previous page).

3. Open the Firmware Loader 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.

6. From the drop-down menus on the RS-232 screen, select your model name (SW2 USB, SW4 USB, or SW4 USB Plus), the appropriate COM port number, and 9600 for the baud rate.

7. Click OK. The firmware selection screen appears.

8. Click Browse to open the Choose Firmware File window, and locate the firmware file that you downloaded. (By default, the file is placed at

c:\Program Files\Extron\Firmware when downloaded from the Extron site.)

CThe firmware file must have a .s19 extension. Uploading any other file type could cause the switcher to stop functioning.

9. On the Choose Firmware File window, double-click on the new firmware file to open it. The Choose Firmware File window closes, and the path to the selected firmware file is displayed in the “Select a firmware file” field.
