AMX Distribution Matrix Precis SD - Manual (Page 25)

Installation & Setup
20 Precis SD Instruction Manual
Attaching External Controllers
The Precis SD can be controlled by attaching an external control device that uses one of the
communication protocols listed below:
BCS (Serial) – ASCII sent over a null modem serial cable via the CONTROL port
XNNet – AMX AutoPatch protocol via all ports (including serial); AMX AutoPatch control
and accessory devices usually connect via the REMOTE port
Important: The ENC LINK (Ethernet RJ-45) connector on the CPU is not a TCP/IP interface and is
used for linking enclosures. The Precis SD is primarily designed as a standalone system, but can be
linked to other AMX AutoPatch Matrix Switchers (Optima, Optima SD, Modula, Epica-128,
Epica-256, and Epica DG; see the instruction manual for the specific product).
Control Options
The communication protocols listed above are used for these control options:
AMX Control Devices
The Precis SD is compatible with a number of AMX control devices. For specific control programming
information, contact your AMX representative.
AMX AutoPatch Remote Control Panels & SBCs
AMX AutoPatch remote control panels and other AMX AutoPatch control devices (SBCs, and
Preset SBCs) usually connect to the REMOTE port on the CPU. For instructions for attaching an
external controller to the REMOTE port, see page 20. For specific information on the remote control
device, see its product documentation.
APControl 3.0 (Serial)
APControl 3.0 software (for control and scheduling) runs on a PC connected to a Precis SD via the
CONTROL port and is available on the AMX AutoPatch CD.
APWeb (TCP/IP)
The APWeb Server (for control, diagnostics, and third-party access) is accessed through a TCP/IP
interface, such as, a web browser (e.g., Internet Explorer). An APWeb Server Module is required
for APWeb. For setup and operation information, see the APWeb Server Module’s documentation
on the AMX AutoPatch CD and at www.amx.com.
Important: Contact AMX regarding limitations and conditions for operating a Precis SD
on a company LAN.
XNNet Protocol (Serial)
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.
BCS (Serial) Control
AMX AutoPatch has developed a command language, BCS (Basic Control Structure), for executing
control operations and for diagnostic purposes. BCS commands are issued via a terminal emulation
program, such as Windows
®
HyperTerminal. For information on BCS commands, see the
BCS Protocol Instruction Manual on the AMX AutoPatch CD or at www.amx.com.
Third-Party Controllers (Serial)
Third-party controllers connect to the CONTROL port (RS-232) on the CPU. If using a third-party
controller, see the controller documentation for setup and operating instructions.
