Instruction Manual – Precis DSP Matrix Switchers
BCS Commands
Precis DSP models can be controlled by entering BCS (Basic Control Structure) commands into a terminal emulation
program (e.g., TeraTerm, PuTTY, or HyperTerminal). 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
Instruction Manual – BCS (Basic Control Structure) Protocol at www.amx.com
.
PC Requirements for BCS
Windows XP Professional
®
or Windows 2000
®

 Terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal)
Serial port
To enter BCS commands, the Precis DSP must be attached to a PC (see “Attaching an External Controller,” on page 17)
running a terminal emulation program such as TeraTerm, PuTTY, or HyperTerminal.
The settings on the PC serial communication software and the enclosure must correspond to each other. For settings
information, see the table on page 18.
When using a terminal emulation program, command characters are entered and sent to the enclosure’s CPU (the
command characters appear in the splash screen when the enclosure responds). When all of the entered characters appear
in the splash screen, the command has been successfully executed.
To establish communication between the Precis DSP and a terminal emulator:
1.
Open a terminal emulation software program.
2. Select the COM port and check that the settings match those in the Precis DSP Serial Port Settings table on page 18.
3. Click OK.
A short splash screen appears followed by “Ready” (see FIG. 8 below).
The system is ready to enter BCS commands to execute switches (see page 30).
Terminal Emulation Program Splash Screen
When power is applied to the enclosure, the terminal emulator displays a short splash screen followed by “Ready”. An
example of a short splash screen is illustrated in FIG. 8 (your system’s splash screen may differ slightly).
Precis DSP models display advanced system information when the command ~scr! is entered (see Appendix A on
page 31). For information on checking the hardware version, see page 32.
Note: AMX reserves the right to add to the contents of the splash screen at any time, without notice.
