Code-Set Description and Overview

B&K uses discrete code-sets to control any or all of its audio/video zones. Code-sets range from code 0-0-0 (zero zero zero) to 1-2-8. This is the same practice that satellite manufacturers use so that one remote con- troller could control three identical satellites. The satellites are first set (via switches or on-screen menus) to be either an A, B or C satellite. When the remote control is set to SAT A, only SAT A responds and so on. In the advanced setup menu of the CT Receiver Code-Sets are assigned to control each zone. B&K applies this theory to each of its zones. Once the codes have been assigned, functions like lowering the volume in Junior's room from the Kitchen keypad is possible. Code-Sets can also control a group of zones (such as upstairs or party modes) or control the whole house (all zones) using Code-Set 0-0-0.

In a basic default system, all keypads are pre-programmed with Code-Set 1-2-8. The CT Receiver monitors which one of the six Zone Control terminals the IR command was received from and responds only in that zone. Thus, as long as each keypad is hard wired to the correct Zone Control terminal, all keypads can be programmed identically using code 1-2-8. However, the user can be provided with powerful convenience fea- tures by utilizing discrete Code-Sets to enable any keypad to control any zone, any group of zones or the whole house. The front panel will not respond to Code Set 1-2-8 received from a remote control.

B&K created 128 different sets of the same CT Receiver commands. These commands will also work with B&K home theater units assigned to the same code set. The primary commands are as follows:

Power State	Tone	Input Sources		Tuner
ZONE	BASS -	SOURCE +	INPUT 5	AM
POWER ON	BASS +	SOURCE -	INPUT 6	FM
POWER OFF	TREBLE -	VIDEO SOURCE +	INPUT 7	BAND TOGGLE
	TREBLE +	DEDICATED IN	INPUT 8	TUNE -
Volume	LOUDNESS	INPUT 1	INPUT 9	TUNE +
		INPUT 2	TUNER	STATION -
MUTE ON		INPUT 3		STATION +
MUTE OFF		INPUT 4
STEREO/MONO
MUTE (TOGGLE)
MASTER VOL+
MASTER VOL-			*This list is not a complete list of commands. For a
			complete list please refer to page 7 of this manual.

Each code-set differs from the next only in the initial IR code identification or prefix, i.e. 128 - Power On. This way a CT Receiver zone can be setup to recognize an intended command no matter what Zone Control ter- minal the command is received from. Thus, any zone can control any other zone (or group of zones) by pro- gramming a remote control or a keypad with the appropriate set or sets of codes from the following choices:

Code Set 000 Controls ALL zones simultaneously. (Multi Zone and Home Theater) Code Set 001-127Can be utilized for group or independent zone operation. (Discrete) Code Set 128 Controls only the zone it is connected to or received from. (Hardware Specific) Code Set 999 Controls a set of B&K ALL commands (Multi Zone and Home Theater)
