Instruction Manual – BCS Basic Control Structure Protocol
Increment/Decrement Method
The Increment/Decrement Method increases or decreases the volume of an output by a step. You may
need to repeat the command to hear an audible difference.
To increase an output’s volume by a step:
1.
Enter the Volume Increment command below. Replace the “
#
”s with the level and output
number(s).
CL#O#VS+T
To decrease an output’s volume by a step:
1.
Enter the Volume Decrement command below. Replace the “
#
”s with the level and output
number(s).
CL#O#VS-T
Volume Increment and Decrement Examples
Note:
If the decibel level requested is outside the range for the selected output, the system will
respond with an “
X
” indicating an invalid value was requested (for a specific audio board’s volume
adjustment range, see the board’s documentaion).
Applying/Removing Mute to Volume
Not all systems with audio support the mute option. If your system supports the mute option, outputs can
be muted and un-muted using BCS commands. Inputs cannot be muted.
Note:
For BCS purposes, VM refers to volume mute, not virtual matrix.
Applying Mute
To mute an output:
1.
Enter the Volume Mute command below. Replace the “
#
”s with the level and output number(s).
CL#O#VMT
Removing Mute
Un-mute returns an output to its previous un-muted volume level. (Entering any other Volume command
for that output will also un-mute the signal).
To un-mute an output:
1.
Enter the Volume Un-mute command below. Replace the “
#
”s with the level and output number(s).
CL#O#VUT
BCS Command
Action
T
Increases volume a step for Output 3 on Level 0
CL0O4 8VS-T
Decreases volume a step for Outputs 4 and 8 on Level 0
