Using Virtual Channels - Polycom SoundStructure C16 Design Manual

Control systems and PCs running SoundStructure Studio may communicate with SoundStructure systems
over the Ethernet interface using port 52774 for open systems and port 52775 for authenticated systems.
Each SoundStructure will support multiple simultaneous IP connections from its Ethernet controller.
Each collection of SoundStructure devices that are linked via the OBAM interface only requires a single LAN
connection to control all the SoundStructure devices. SoundStructure devices also support having multiple
linked devices with each device connected via Ethernet. Connecting to two networks could be used to
provide redundancy on the same network or can be used to connect the SoundStructure devices to more
than one network.
Multiple network connections can be on the same network or on different subnets as shown in the following
figure.

The SoundStructure Ethernet interface can be configured to have either a static IP address or can accept a
dynamic IP address from a DHCP server. By default the SoundStructure products will accept an IP address
from a DHCP server. If there is no DHCP server available, a Link-Local IP address will be created of the
form 169.254.abc.def.

Using Virtual Channels

As described in Introducing SoundStructure Design
individual physical input or output channel. A virtual channel may also be a stereo pair of physical inputs or
output channels. The virtual channel name that is created when the virtual channel is defined by the A/V
designer is used to refer to that particular input or output instead of using the physical channel number. For
example, the designer would define the virtual channel "Podium mic" that is connected, for example, to input
physical channel 9 and then refer the virtual channel as "Podium mic". Once a virtual channel is defined, it
is always used to reference that particular signal or signals.
