Example 1: Switched and isolated network configuration
NOTE: It is immaterial, in this example, which codec is the encoder and which is the
decoder. These functions are not identified in figure 6.
Figure 6 shows two VNC 325 codecs that are configured to work across two switched and
isolated networks. Codec 1 is configured as the controller, via LAN port 1. The controller
handles all normal system configuration and control via its web interface.
This example consists of two networks, connected to the VN-Matrix system as follows:
• Network 1, connected to LAN port 1 (RJ-45 port), the “green” network — The
encoder streams video on this network and it is also used for system control and
monitoring.
NOTE: Selection of this network for streaming is via the built-in HTML network
interface. This selection is defined in the management interface, described
later (see “Configure Encoders or Decoders“).
• Network 2, connected to LAN port 2 (the fiber optic port), the “red” network —
This network is separated from the streaming network. This network also can be used
for system control and monitoring if preferred.
NOTE: The controller codec responds to inquiries on LAN port 2 as well as LAN
port 1.
• A network management server can also be integrated if required.
