AMX Modula Instruction Manual page 22

Overview and General Specifications
BCS Serial Control Protocol
The Modula can be controlled with an external serial controller that sends and receives ASCII characters
via an RS-232 serial 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 (such as, HyperTerminal) running on a PC. For
information on BCS commands, see the Instruction Manual – BCS Basic Control Structure Protocol on
the AMX AutoPatch CD or at www.amx.com.
Third-Party Controllers
A third-party controller can also be attached to an Modula enclosure. If using a third-party controller, see
the controller documentation for operating instructions.
Note: Advanced programmers who want to design their own control programs can use AMX's
AutoPatch XNNet protocol. The "AMX AutoPatch CD" includes the XNNet Communication Library,
an interface that supports C, Java, and Visual Basic and has examples of the XNNet protocol in use.
