Appendix A – Product Specific BCS Commands
39
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

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)
