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’s serial port and running the Software Installer.

6.1SOFTWARE VERSION IDENTIFICATION

To find out which software version is in your AVM 50, press STATUS and the display will show it. The latest software is available from our web site. A list of changes comes with the download. If operating manual updates aren’t also included, or if you haven’t been keeping up with the upgrades, it’s a major upgrade, so download and use the latest operating manual as well.

6.2SOFTWARE 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.

6.3SOFTWARE UPDATING VIA YOUR COMPUTER

To update the Software through your computer, you will need the following:

•Access to the Internet.

•Serial cable (the common kind, which is straight wired, one end DB9 male and the other end DB9 female. A null-modem cable, which looks identical, does not work since pins 2 and 3 are switched).

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.

•1 MB free space on the hard drive.

•Serial port. The Software Installer automatically 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 (its driver program must also be installed on your computer). Make sure it’s one that’s Windows-certified. 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 by the warranty.

Before running the Installer, check your computer’s power management settings – particularly if using a laptop – to ensure that the Software Update does not get interrupted while running.
