Two Cable PCU Frame Connection
PCU to Kayenne
GV K-Frame XP Network Connection Methods
The PCU Ethernet switch to GV K-Frame XP Video Processor Ethernet switch cable
connection is used for Menu Panel communications. The second cable connects the Panel
PCU directly to the Frame’s Ethernet switch. Using two cables provides additional Ethernet
communications throughput (to support Image Store file operations) and also offers
redundancy. Because the Menu Panel and the Control Panel have independent cable
connections, failure of one of these cables will not completely disable the system. Either the
Menu Panel or the Control Panel will remain operational after a single network cable failure.
Kayenne Suites and Control Surfaces
The GV K-Frame XP Control Panel system flexibility allows you to locate control surfaces in
physically separate locations.
Custom multi-pin cable runs are limited to 15 meters (50 ft.) If this length is sufficient, a
single PCU can be used for an entire multi-suite system.
