Connecting Logic Ports - Polycom SoundStructure C16 Hardware Installation Manual

Hardware Installation Guide for the Polycom SoundStructure

Connecting Logic Ports

There are two logic ports, called Remote Control 1 and Remote Control 2, on the rear-panel of each
SoundStructure device. Please check the software release notes and Chapter 3 of the SoundStructure
Design Manual for information concerning logic pin functionality.
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.
