Hardware and Software Compatibility
The following table lists Polycom RealPresence Group system software versions that are compatible with
RealPresence Group system hardware.
Points to note about downgrading:
• If you use your RealPresence Group system within a DoD environment, be sure to contact your
Information Assurance Office (IAO) for approval before using a USB device with your system.
• Before downgrading, verify the interoperability of the camera, hardware, and software versions you
plan to install.
• If you downgrade the RealPresence Group system software, EagleEye Director is automatically
downgraded to a compatible version.
• To determine the software version you are using, go to System in the local or web interface.
• If you downgrade the RealPresence Group system software, you must also downgrade the
Polycom Touch Control software.
• Because of changes in software functionality and the user interface, some settings might be lost
when you upgrade or downgrade. Polycom recommends that you store your system settings using
profiles and download your system directory before updating your system software. Do not
manually edit locally saved profile and directory files.
For more information about storing system settings, refer to the Administrator’s Guide for the
Polycom RealPresence Group Series.
