Polycom RealPresence Digital Breakout, Codec
Adapter
The Polycom RealPresence Digital Breakout, Codec adapter allows the input of HDMI and Serial for control
into an HDCI input on RealPresence Group Series codecs. You can also use this adapter with the Polycom
RealPresence Digital Breakout, Camera to extend the distance between an EagleEye IV camera or an
EagleEye Producer and a RealPresence Group Series codec.
Recommendations for Use
● Use with HDCI Polycom EagleEye IV camera cable. Either 2457-64356-001 (3 m), 2457-64365-100
(1m), or 2457-64356-018 (457 mm).
● Use with certified HDMI compliant cable.
● Use with certified EIA/TIA-RS-232 cable. Use straight-through type, not crossover.
● Do not hot plug the serial cable. Disconnecting or connecting the RS-232 cable during operation may
cause unexpected system behavior. If this happens, cycle the power to the codec or camera to
eliminate this issue.
● Polycom tested with cables less than 3 meters in a normal environment. The maximum cable length
possible depends on the signal quality of the HDMI and serial signals at the output of the Digital
Breakout Adapter (DBA) and associated cables, if the mating device has an equalizer, and the
electrical noise in the installed environment. To ensure proper operation with all devices, the HDMI
and EIA/TIA-RS-232 specs should be met at the input to all mating devices.
● The following HDMI features are not provided: DDC for EDID support, HDCP, and CEC.
● Without EDID support, digital (HDMI) sources connected to the system must have a mechanism for
bypassing EDID detection, for setting up the video resolution manually, or using a fixed video
resolution. Refer to the Video Format Resolutions table below for supported resolutions.
● The signal quality is dependent on the quality of the HDMI and serial signals at the output of the DBA
and associated cables, if the mating device has an equalizer, and the electrical noise in the installed
environment. To ensure proper operation with all devices, the HDMI and EIA/TIA-RS-232 specs
should be met at the input to all mating devices.
