Command Protocol Reference Guide
Introduction
This chapter describes the SoundStructureâ„¢ command protocol used to con-
trol and configure the SoundStructure products via the RS-232 and Ethernet
interfaces. The target audience for this document is the control system pro-
grammer and other application developers who need to understand how to
control and configure SoundStructure devices.
The purpose of the SoundStructure command and control protocol is to pro-
vide an interface for configuring SoundStructure devices and controlling their
operating parameters. With SoundStructure devices, a collection of Sound-
Structure devices linked over OBAMâ„¢ will behave as a single device and
controlling the collection of devices only requires one connection to a control
interface on any of the linked devices.
SoundStructure Control Interfaces
The SoundStructure control protocol has been designed so that all features are
available over all interfaces. Some features will only be practical over the
higher bandwidth connections (for example, firmware updates take much less
time over the ethernet interface than the RS-232 interface and signal meters are
more responsive over the ethernet interface). While the SoundStructure Studio
Windows software makes full use of the control protocol to configure and con-
trol SoundStructure, user applications, such as AMX® and Crestron® control
systems will typically only use a subset of the control protocol to adjust set-
tings and monitor system parameters for functions such as muting, volume
control, and dialing.
