54 KAYENNE — Installation Planning Guide
Section 4 — System Cabling
Kayenne control surface components and Menu Panels from the PCU
through the custom multi-pin cabling. Additional Frame and PCU power
supplies are available for redundancy.
Serial digital video and key input and output signals are connected to the
Kayenne Video Processor Frame. Specified MatchDef Input pair and
SetDef Output pair connectors on the Frame can be used for internal format
conversion (an optional feature). Separate Video Reference inputs are avail-
able for HD and SD formats.
Network Cabling
Network connections are required between the Kayenne Video Processor
Frame and the PCU. The PCU routes network communications to and from
the Control Panel Stripes and Menu Panels, using custom multi-pin cables.
The Ethernet switches built into the Kayenne Frame and PCU auto-detect
speed and polarity, and are 10/100/1000 Mbps capable. Either straight-
through or crossover Ethernet cabling can be used. Available Ethernet con-
nectors may be connected to the Facility LAN or other devices, as needed.
However, should the Kayenne Frame or PCU power down, the internal
Ethernet switches will also power down, interrupting communication to
devices connected to that Frame’s or PCU’s internal Ethernet switches.
Only connect devices that are Kayenne system related.
The use of two Ethernet cables to connect the PCU to the Frame is recom-
mended (
Figure 56 ).
Figure 56. PCU to Frame Network Connection Methods
The PCU Ethernet switch to Frame 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
