Each SoundStructure device has a rear-panel Ethernet interface for connecting
to the local area network as shown in the following figure. Connect to the
SoundStructure device using port 52774 and telnet communication. There is
no user login required to interface to SoundStructure devices over this port.
Control systems and PCs running SoundStructure Studio may communicate
with SoundStructure over this interface using port 52774. 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
