Polycom SoundStructure C8 User Manual

Linking Multiple SoundStructure Devices with OBAM
7 - 3
A device’s bus ID is automatically assigned to SoundStructure devices based
on how the systems are linked. The device that only has a connection on the
OBAM Out connector will have a bus ID of 1 and will be referred to as the
Master device. The remaining devices are numbered sequentially and are
referred to as Slave devices.
OBAM Cable Length
The OBAM cable supplied is 12 inches long and is designed to connect
between SoundStructure devices within an equipment rack. 1394B extenders
are not compatible with the OBAM interface.
Multiple Telephony Cards
While the devices are powered down, any required telephony cards should be
installed into the system. Telephony cards should be installed starting with the
Master device and working through the slave devices as shown in the follow-
ing figure where one TEL1 card is installed into the master device of a three
SoundStructure system.
