Updating an iAM-AUDIO Remotely
Remote upgrading is available for any networked iAM-AUDIO that is currently at
version 3.2-0 or higher. This feature is useful if it is inconvenient to physically
access some of the iAM-AUDIO units in the system to insert a flash drive. You may
download an update file from the Wohler Web Site (
www.Wohler.com
) and access
the downloaded file directly from the Web GUI.
Use the following steps to remotely upgrade an iAM-Audio unit:
1.
Download the update file into the computer containing the Web GUI. Refer to
the
