PRELIMINARY
Updating Firmware
If the need arises, you can update the PVS’s rmware without taking the unit out of
service. Follow the directions below.
Check the Extron Web (www.extron.com) site for firmware-related documents,
instructions, patch files, and new firmware files before loading new firmware
into the switcher. Extron recommends that you read the rmware release notes
(available from the Web site www.extron.com) before beginning the firmware
update.
This procedure must be performed using a PC, with the PC’s RS-232 port directly
cabled to the PVS’s front panel Cong port.
N Each time you replace existing firmware, the switcher is reset to the factory
default settings.
1. Visit the Extron Web site (www.extron.com) and download the Firmware
Loader le (FWLoader.exe) to your PC. Write down the lename and location
for later use.
2. Locate (on the Web site) the appropriate rmware le (PVS 204SA) you want
to update. It has a lename ending in .s19 (PVS204_Vxxx.s19), where Vxxx
indicates the version number (x.xx). Download the rmware from the Web
site. The program automatically stores the firmware file on the PC in
C:\Program Files\Extron Electronics\Firmware (a folder specic to that
version). Write down the lename and location for later use.
C
The firmware update file must have a filename extension of .s19. If the file
does not have that extension, it could cause the unit to stop functioning.
3. Connect a 2.5 mm conguration cable (Extron part # 70-335-01) between the
front panel Cong port of the PVS and the serial (RS-232) port of the PC, and
power up the PVS and PC. See chapter 3, “Operation and Setup”, “Front
Panel Features and Operation” section, for details.
4. On the PC, select Start > All Programs > Extron Electronics > Firmware Loader
(folder)> Firmware Loader, and start the program.
5. Select the Com port and Baud rate. Click OK. The PVS 204SA should be
detected automatically.
