Polycom SR12, C12, C16, C8 manual Device ID’s

Hardware Installation Guide for the Polycom SoundStructure C16, C12, C8, And SR12

Because the OBAM interface is bi-directional, data will flow in both directions on the single cable between devices. Due to this bi-directionality, do not loop the OBAM link connections (as follows).

Once the devices are connected over OBAM, the SoundStructure devices will behave as one large audio device, in other words, all the inputs from all the SoundStructure devices are available on all the devices. Any combination of SoundStructure C16, C12, C8, and SR12 devices may be linked together up to a total of eight devices.

When the SoundStructure devices are connected over the OBAM Link, the OBAM Input Status LED illuminates when there is a valid connection between the OBAM IN port on this device and an OBAM OUT port on a second SoundStructure device. This LED will not illuminate unless there is a valid connection between the two devices. The OBAM Output Status LED illuminates when there is a valid connection between the OBAM OUT port on this device and an OBAM IN port on a different SoundStructure device. This LED will not illuminate unless there is a valid connection between the two devices.

A 12-inch OBAM cable is provided with each SoundStructure device. Should longer OBAM cables be required, standard IEEE1394b "beta" cables may be used. The maximum length of any single link between devices is 10 feet (3 m). See OBAM Link for more details. An OBAM link cable may be tested by inserting the same cable into the OBAM IN and OBAM OUT ports. If the OBAM input and output status LEDs illuminate, the OBAM cable is fully functional.

Device ID’s

When multiple devices are connected via the OBAM interface, internal SoundStructure device ID’s are assigned automatically based on the OBAM connections. The device that has no OBAM IN connection will be device 1. The device connected to that unit will be device 2, and so on until the last device -
