node address. The Subnet mask defines the dividing line between the two.
The first three octets of Subnet mask provide the network address; the
fourth is the node address. Nodes with the same network address can com-
municate directly with each other, while nodes with different network
addresses normally do not communicate directly.
The Karrera K-Frame system uses Ethernet switches built into the Video
Processor Frame. The switch provides isolation between port pairs, pro-
viding deterministic communication for panel and frame messaging, and
also allows Control Panel and Menu Panel communication for DPOPs. All
nodes must also have the same network address and be given a different
node address.
Gateway IP Addresses
A gateway IP address can be entered to allow communication with devices
not located on the local Karrera K-Frame system network. Communication
outside the local network requires using a configured network gateway
server, a description of which is beyond the scope of this document. See
your network administrator for information about gateway server installa-
tion and configuration.
Karrera K-Frame Default IP Addresses On Isolated Network
Each Karrera K-Frame system is shipped with default IP addresses (see
Factory Default Network Settings on page 78 ). Grass Valley has chosen these
default IP addresses to make Karrera K-Frame configuration easy. Karrera
K-Frame devices should communicate with each other right out of the box
when properly connected on an isolated network.
Connecting to an Existing Network
Additional network configuration is required if you connect the Karrera K-
Frame Ethernet LAN to your facility Ethernet backbone, install additional
Karrera K-Frame system components, or have multiple Karrera K-Frame
systems on the same network cabling. For example, if more than one
Karrera K-Frame system resides on the same network, the IP address of
each additional Karrera K-Frame device must be changed before it is con-
nected to the network.
To enable communication between Karrera K-Frame and other facility
devices, you will need to change the Karrera K-Frame system default
network addresses to match the facility address, or place a router between
Karrera K-Frame and the facility networks. This complexity of network
configuration is beyond the scope of this manual. Consult a networking
expert if such networking is desired.
