6. SOFTWARE UPDATING
The operational characteristics of the AVM 50 are controlled by software that can easily be upgraded via the
RS-232 port on the Rear Panel. New software can be downloaded from our web site, and then transferred by
connecting the AVM 50 to your computer.
6.1 SOFTWARE VERSION IDENTIFICATION
To find out which software version is in your AVM 50, press STATUS and the display will show it. The latest
software and manual are available from our web site. A list of changes comes with the download.
6.2 SOFTWARE UPDATING VIA YOUR DEALER
If you do not have a computer or wish to do software updates yourself but still want to have them done,
please make arrangements with your dealer. Whether your dealer comes to your theater to do the update,
or you bring your AVM 50 to the dealer, the dealer may charge for this service.
6.3 SOFTWARE UPDATING VIA YOUR COMPUTER
To update the Software through your computer, you will need the following:
• Internet access.
• Serial cable – straight wired, one end DB9 male and the other end DB9
female. A null-modem cable, which has pins 2 and 3 switched, does not work.
Typically, a serial cable up to 100 feet (33 metres) long will work. You may also install the cable
permanently to enable easy future updates. When it’s not in use, disconnecting it either behind the
computer or the AVM 50 is recommended, to prevent the possibility of a ground loop.
Computer System Requirements:
• Win9x, NT, ME, 2000, or XP.
• 10 MB free space on the hard drive.
• Serial port. The Software Installer detects the port being used (COM1 to COM6).
If your computer does not have a serial port but has a USB port, you will need a USB-to-serial
adapter. Make sure it’s one that’s Windows-certified, and use the latest driver from the
manufacturer’s web site. Some no-name models have been found to cause operation to freeze.
Reviving a AVM 50 that was made inoperable by an inadequate USB-to-serial adapter is not
covered under warranty.
Before running the Installer, check your computer’s power management settings, particularly if using a
laptop, to ensure that the installation
