Command Protocol Reference Guide
Introduction
This chapter describes the SoundStructure™ command protocol used to
control and configure the SoundStructure products via the RS-232 and
Ethernet interfaces. The target audience for this document is the control
system programmer 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
provide an interface for configuring SoundStructure devices and controlling
their operating parameters. With SoundStructure devices, a collection of
SoundStructure devices linked over OBAM™ 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
SoundStructure devices provide several physical interfaces that can be used
for communication via the control protocol. As shown in the following figure,
these interfaces include the rear-panel RS-232 and Ethernet. These physical
interfaces provide a diverse set of communication capabilities ranging from
100 Mbps with multiple sockets (Ethernet) to 9600 bps with only a single data
stream (RS-232).
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
