BCS (BASIC CONTROL STRUCTURE) COMMANDS

2. While the Lock key is flashing, enter the
enclosure's password (the default password
from the factory is the first five Level keys,
going left to right).
‡
If you locked the Control Panel, the
Lock key light stops flashing and
shines constant; all other lights on the
Control Panel turn off.

If you unlocked the Control Panel, the
Lock key light turns off and the panel is
in Switch mode.
BCS (BASIC CONTROL
STRUCTURE) COMMANDS
BCS is a set of alphanumeric characters that
allow a PC or other control device to send
commands to your Precis through the serial
connector (on the CPU). To establish
communication between your PC (personal
computer) and your Precis, attach the PC to the
serial connector and use terminal emulation
software (such as Windows95 HyperTerminal).
BCS commands are a subset of the X
communications protocol.
Command Line Formats
To generate commands, enter them using the
following formats in which "#" represents any
valid level, local preset, input, or output number
and "^^^" represents a decimal number to the
tenth place without the decimal marker (for
example, 100 = 10.0 and 35 = 3.5).
For multiple outputs or multiple local presets,
enter a space between each number.

O is the letter O, not the number zero (0).
q
To execute a switch:
CL#I#O#T or CL#O#I#T
q
To verify switch status:
SL#O#T or SL#I#T
q
To execute a local preset:
RL#P#T
q
To disconnect a switch:
DL#O#T or DL#I#T
q
To adjust absolute volume*:
CL#O#VA^^^T
q
To adjust relative volume*:
CL#O#VR^^^T
q
To adjust increment/decrement volume*:
CL#O#VS+T or CL#O#VS-T
q
To apply volume mute*:
CL#O#VMT
q
To apply volume un-mute*:
CL#O#VUT
*To use these commands your system must
contain audio boards with Volume Adjustment
capability. In addition, the mute and un-mute
commands require a Precis with a 32-bit CPU. If
the command specifies a decimal number, the
number must fall within the adjustment range for
the specific type of audio board.
