Instruction Manual – BCS Basic Control Structure Protocol
Generating BCS Commands
Important:
We strongly recommend checking Appendix A (page 25) for information about BCS
commands specific to your equipment. Not all systems support all BCS commands.
Basic and Preset Commands
To generate basic and preset BCS commands:
1.
Enter commands using the formats from the tables below. Replace the “
#
”s with the appropriate
level, input (source), output (destination), local preset, or global preset number.
Digital Output Volume and Digital Input Gain Commands
To use audio commands, your system must contain audio components that support the specific audio
commands. The decibel level resulting from an output volume or input gain adjustment command
must
fall within the range of the audio specifications (for a specific audio output volume or input gain
adjustment range, see the specifications for that specific audio board or connector set in the product’s
instruction manual). Audio commands can only be executed on levels that switch audio.
Important:
Do not use leading zeros for gain values in audio commands.
To generate digital output volume and digital input gain BCS commands:
1.
Enter commands using the formats from the tables below. Replace the “
#
”s with the appropriate
level and input (source) or output (destination) number. Replace the “
^^^
” with the decibel level
entered as an integer number representing the desired decibel value multiplied by 10 (e.g., +8.0 dB
is entered as 80 and -40.5 dB is entered as -405).
Caution:
We strongly recommend that input gain adjustments be made only by a qualified installer
or dealer.
Note:
For information on DSP (Digital Signal Processing) commands, see page 20.
