Polycom SoundStructure C16 Hardware Installation Manual page 27

Each Remote Control connector includes eleven logic inputs, eleven logic
outputs, an analog gain control input, a +5 V supply capable of providing up
to 500 mA, and a logic ground. Internal to the SoundStructure device is a fuse
that will trigger if the current draw on Pin 1 exceeds 500 mA. The fuse will
reset itself once the excessive load is removed.
As there are two logic connectors, there are a total of twenty-two logic inputs,
twenty-two logic outputs, two analog gain inputs, and two +5 V supplies and
two logic grounds per SoundStructure device. The pinouts and signal
definition are shown in the following figures.
