Precis SD Instruction Manual
Configuration Information & Control Options
The factory configuration of the Precis SD is constructed internally by the CPU upon initial boot up of
the system and contains routing and control information for that particular model of (for model numbers
and descriptions, see the “Applicability Notice” on page 7).
Configuration Information
As shipped from the factory, the Precis SD supports Device Discovery (firmware v1.4.1 required).
The factory configuration contains 3 virtual matrices for switching signals: VM 0 = audio-follow-video,
VM 1 = video, and VM 2 = audio.
Important: Unless you need to modify the system, you will not need to use XNConnect
(configuration software provided on the “AMX AutoPatch CD” shipped with each system).
You can use XNConnect to discover the factory configuration, modify the information, save it as an .xcl
file, and load the file to the system’s CPU (see “Appendix A – Managing Configuration Files” on
page 45). When an .xcl file is loaded to the system, it replaces the factory configuration on the CPU.
Configuration file modifications include basic tasks, such as creating local presets, customizing input
and output channel names for control display (e.g., in the APWeb or APControl interface), and setting
the control panel password. A compatible .xcl configuration file is also provided on the CD.
Control Options
Precis SD systems support three different protocols: BCS (as ASCII characters sent through the
CONTROL port), XNNet, and TCP/IP. Several different control options are available, and multiple
control methods can be used on the same system.
Front Control Panel
The Precis X/Y Control Panel (standard on all Precis SD systems) controls the system’s switches and
attributes, as well as providing routing verification, redundant control, and troubleshooting. For more
information, see the “Control Panel Operation” chapter on page 35.
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 Control Software
Precis SD enclosures can be controlled using AMX AutoPatch software:
APControl 3.0 – for control and scheduling
Uses CONTROL (serial) port located on the CPU
Runs on a PC connected to the CONTROL port
Download* from the AMX AutoPatch CD
APWeb Server (TCP/IP) – for control, diagnostics, and third-party access
Uses the CONTROL port located on the CPU for connecting to an APWeb Server
Module
Accessed through a TCP/IP interface, such as, a web browser (e.g., Internet Explorer)
Contact AMX regarding limitations and conditions for operating a Precis SD
on a company LAN (Local Area Network)
