PRELIMINARY
Troubleshooting
If the SW USB detects a non-standard keyboard or mouse, an error condition may
occur in which the Exec Mode LED blinks and the SW USB reboots in a repeating
cycle. If this happens, and rebooting does not resolve the issue, set the host
emulation DIP switch(es) to Off, and then wait for the switcher to reboot. You will
not be able to use host emulation with that keyboard or mouse.
Peripheral emulation (SW4 USB Plus only)
In addition, the SW4 USB Plus emulates a mouse and keyboard to the computer
or other input device that is connected to the selected input port. This emulation
of peripheral devices is constant, whether or not a keyboard or mouse is actually
connected to these ports, facilitating problem-free boot-up. Keyboard and mouse
emulation is always present on the inputs of the switcher.
Updating Firmware
Extron periodically updates product rmware in conjunction with the release of
new software revisions. Before updating any Extron product to the latest revision
level, be sure to read the supplied release notes or contact Extron Technical Support
to determine if your product requires a firmware update.
You can find out what version of firmware is currently loaded on your switcher by
entering the SIS “Q” command via the RS-232 interface (see the Query firmware
version command in chapter 4, “SIS
™
Conguration and Control”).
New rmware versions for the SW USB can be downloaded from the Extron Web
page. After you install the new firmware on your computer, you can upload it to
the switcher using either SIS commands (see the “Command/response Table for
SIS Commands,” in chapter 4) or the Firmware Loader software (see “Loading the
firmware to the switcher using Firmware Loader”, later in this chapter).
Downloading and installing the Firmware Loader
Extron recommends using the Firmware Loader software to update the rmware
on the SW USB. If you do not already have the Firmware Loader software installed
on your computer, download it as follows:
1
. Go to the Extron Web site at www.extron.com and click the Download tab.
2
. On the Download Center screen, click the Software link on the left sidebar
menu.
3
. On the next Download Center screen, locate and click the Download link for
the Firmware Loader.
4. On the next screen, enter the requested information, then click the
Download fw_loadernxnxn.exe button (where n is the Firmware Loader
version number).
5
. Follow the instructions on the rest of the download screens to save the
executable Firmware Loader installer file to your computer. Note the folder to
which you saved the file.
