Overview & General Specifications

Control Options

Levels for Switching
The Precis LT was pre-engineered at the factory to execute switches on VM 0 (the default level of
audio-follow-video), VM 1 (video), and VM 2 (audio).
Front Mounted Control Panel
Precis LT systems can be controlled with the control panel (see "Control Panel Operation" on page 37)
or with one of the following external control options.
AMX Control Devices
Precis LT enclosures are compatible with a number of AMX control devices. For control programming
information, see the instruction manual for the specific interface.
Control Software
Precis LT 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
A Precis LT system can be controlled with an external serial controller that sends and receives ASCII
characters via the Control port. AMX AutoPatch has developed a command language, BCS
(Basic Control Structure) protocol, for programming control operations and for diagnostic purposes.
BCS commands* can be entered into a terminal emulation program (e.g., HyperTerminal) running on
a PC.
* For information on BCS commands, see the BCS Protocol Instruction Manual on the AMX AutoPatch
CD or at www.amx.com.
Third-Party Controllers
A third-party controller can also be attached to a Precis LT enclosure via the Control port. If using a
third-party controller, see the controller documentation for operating instructions.
