Instruction Manual – BCS Basic Control Structure Protocol
Precis (300 MHz)
Precis (300 MHz) models support the following items:
General Commands and Conditions
Executing and disconnecting switches (see page 6 and page 7)
Verifying signal status (see page 8)
Executing local presets – predefined in XNConnect (see page 10)
Specific Commands and Conditions
Precis (300 MHz) models with front control panels will accept BCS commands while the
panel is locked, but BCS commands cannot be used to unlock the front panel
A range of numbers cannot be entered by using a colon “:”
To designate a range of numbers, insert a space between each number in the range
Does not support global presets
Does not support auxiliary commands
Supports limited error code reporting. An “E” appearing as the result of a Status command
indicates a communication failure between the CPU and the control panel. To establish
communication, use the control panel to execute a switch or power down and then power up
the system
Audio Commands (systems that support digital gain and volume control)
If control panel has a Volume Adjust Key, then the system supports the following audio commands:
Digital output volume control – absolute, relative, and increment/decrement methods
(see page 13)
Verifying volume status (see page 15)
Digital input gain control – absolute, relative, and increment/decrement methods (see page 16)
Verifying digital input gain status (see page 18)
Precis HT
Precis HT models support the following items:
General Commands and Conditions
Executing and disconnecting switches (see page 6 and page 7)
Verifying signal status (see page 8)
Executing local presets – predefined in XNConnect (see page 10); supports 1280 local presets
Specific Commands and Conditions
Precis HT models will accept BCS commands while the front control panel is locked, but BCS
commands cannot be used to unlock the front panel
A range of numbers cannot be entered by using a colon “:”
To designate a range of numbers, insert a space between each number in the range
Does not support global presets
Does not support auxiliary commands
Supports limited error code reporting. An “E” appearing as the result of a Status command
indicates a communication failure between the CPU and the control panel. To establish
communication, use the control panel to execute a switch or power down and then power up
the system
Audio Commands (for analog audio signals only)
Digital output volume control – absolute, relative, and increment/decrement methods
(see page 13)
Verifying volume status (see page 15)
Digital input gain control – absolute, relative, and increment/decrement methods (see page 16)
Verifying digital input gain status (see page 18)
