Configuration & Control - AMX Precis DSP Instruction Manual

Overview & Specifications
Configuration & Control
Configuration Information
Precis DSP systems are pre-engineered to switch stereo audio for two configuration sizes (8x8 and
18x18).
Control Options
Precis DSP systems support two different protocols: BCS (as ASCII characters sent through the
RS-232 serial port) and TCP/IP (with external APWeb Server module). Several control options are
available for Precis DSP systems.
AMX Control Devices
The Precis DSP is compatible with a number of AMX control devices. For control programming
information, see the instruction manual for the specific interface.
APGraphic EQ CrossBar
The APGraphic EQ software has a CrossBar (interface with crosspoints for switching) that can be used
for ongoing control after it is used for system setup.
Control Software
Precis DSP enclosures can be controlled using AMX AutoPatch software:
* If your AMX account has the required permissions, the program can be downloaded from
www.amx.com.
BCS Serial Control Protocol
The Precis DSP can be controlled with an external serial controller that sends and receives ASCII
characters via the CONTROL (RS-232) port. AMX AutoPatch has developed a command language,
BCS (Basic Control Structure) Protocol, for programming control operations and for diagnostic
purposes. BCS commands are issued via a terminal emulation program (such as, HyperTerminal)
running on a PC. BCS command equivalents for all DSP functionality adjustments are provided for
advanced users and programmers who wish to create their own control programs; see the BCS Protocol
Instruction Manual on the AMX AutoPatch CD or at www.amx.com.
Third-Party Controllers
Third-party controllers connect to the CONTROL (RS-232) port on the enclosure's rear. If using a
third-party controller, see the controller documentation for setup and operating instructions.
XNNet Protocol
Advanced programmers who want to design their own control programs can use AMX AutoPatch
XNNet protocol. The AMX AutoPatch CD includes the XNNet Communication Library, an interface
library that supports C, Java, and Visual Basic and has examples of the XNNet protocol in use.

APControl 3.0 (Serial) – for control and scheduling
Runs on a PC connected to the CONTROL (RS-232) port on the Precis DSP
Download* from the AMX AutoPatch CD
Uses a setup wizard; system parameters (VMs and I/O channels) must be entered
Operation information is in the Help file
APWeb Server (TCP/IP) – for control, diagnostics, and third-party access
Uses RS-232 port located on the enclosure for connecting to an APWeb Server Module
Accessed through a TCP/IP interface, such as, a web browser (e.g., Internet Explorer)
Setup and operation information are in the APWeb Server Module's documentation on
the AMX AutoPatch CD or at www.amx.com
