Network Management
8 - 7
Depending on the network router configurations in the network, SoundStruc-
ture device discovery may not work across different subnets. However it is
still possible to remotely configure SoundStructure devices if the IP address of
the device is known as the IP address may be typed in directly in the Connect
to Devices user interface.
AMX Beacon
The SoundStructure devices comply with the AMX Dynamic Discovery Proto-
col and send a UDP broadcast to multicast address 239.255.250.250 port 9131
at random intervals between 30 to 60 seconds.
The broadcast beacon depends on the particular SoundStructure device model
and is formatted as shown below.
AMXB<-UUID=001122334455><-SDKClass=AudioConferencer><-Make=Polycom>
<-Model=SoundStructureC16><-Revision=1.0.0><Config-Name=SoundStructure
C16 Configuration> <Config-URL=http://172.22.2.109/>
where 001122334455 is the MAC address of the SoundStructure C16 device in
this example.
RS-232
The RS-232 interface is capable of running up to 115,200 bps and has a default
rate of 9,600 bps, eight data bits, no parity, one stop bit (8-N-1). The pinout of
the connection and the recommended straight-through cabling to a control
system is shown in the following figure.
The settings of the RS-232 port may be changed with the ser_baud and
ser_flow settings as follows:
set ser_baud 1 38400
sets the RS-232 baud rate to 38400 bps. See Appendix A for additional informa-
tion concerning the RS-232 commands.
