Instruction Manual – BCS Basic Control Structure Protocol
Precis LT
Precis LT 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)
Specific Commands and Conditions
The Precis LT uses Level 1 for video and Level 2 for audio. To route video or audio signals
separately, enter Level 1 for video only or Level 2 for audio only. Precis LT
does not
recognize Level 0 (L0)as part of a BCS command. To achieve the equivalent of routing
signals on Level 0 (audio-follow-video), either omit the level command, (CI3O8T) or enter
both level numbers by entering a space between each number (CL1 2I3O8T)
Does not support audio commands
Does not support global or local preset commands
Does not support using a colon “:” to designate a range of destination numbers in multiple
number entries. To designate a range of numbers, insert a space between each number in the
range
Precis SD
Note: This section also applies to any Precis (500 MHz) models built before the Precis SD was
released.
Precis SD 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); this product supports
64 local presets
Defining and executing global preset (see page 11); this product supports 64 global presets
Error Code Reporting (see page 41)
Specific Commands and Conditions
Precis SD 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
Executing local presets – predefined in XNConnect (see page 10)
Supports auxiliary commands
Supports diagnostic commands
To designate a range of numbers: enter the first number in the range, followed by
a colon “:”, and then enter the last number in the range
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
