88 KAYENNE K-FRAME — Installation & Service Manual
Section 4 — System Cabling
CAUTION The facility network used for your K-Frame system (and other video produc-
tion equipment) should be kept separate from any external network, to
prevent network traffic from adversely affecting K-Frame system operation.
Network Cabling
Network connections are required between the K-Frame Video Processor
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 K-Frame Video Processor 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 connectors may be connected to the Facility LAN or other devices,
as needed. However, should the K-Frame Video Processor or PCU power
down, the internal Ethernet switches will also power down, interrupting
communication to devices connected to that K-Frame’s or PCU’s internal
Ethernet switches. Only connect devices that are K-Frame system related.
The use of two Ethernet cables to connect the PCU to the K-Frame Video
Processor is recommended.
Figure 64. PCU to K-Frame Network Connection Methods
The PCU Ethernet switch to K-Frame Video Processor Ethernet switch
cable connection is used for Menu Panel communications. The second cable
connects the Panel PCU directly to the K-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 K-Frame
system. Either the Menu Panel or the Control Panel will remain operational
after a single network cable failure.
