document for more details.
The Set favorite command, like the Zone Specific favorite preset bitmaps, can also be used to
attribute favorite settings to zones, but from a Preset centric point of view. This command allows
setting the favorite preset attribute of particular logical zones for a specific preset. By contrast, the
Zone Specific favorite preset bitmaps allow attributing various presets as favorite for a particular
zone.
NOTE: The specifier A is used, as the F specifier was already used for Format Specification.
For example, the following depicts setting the Favorite Settings of preset 10h (16 decimal) in an
otherwise factory default CT 610 which as Logical Zones 0, 3, 4, 11, 12, 13, 14, 15, and 16:
(0,S,A=10,0=1,3=1,4=0;0459) Attribute Zones 0 and 3 as favorite, and 4 as not for
Preset 10h (16 decimal)
(0,E,S,A=10,0459;0364) Echo response
(0,G,A=10;01E9) Get command to verify previous Set example
(0,E,G,A=10,01E9;0365) Echo response
(0,R,A=10,0=1,3=1,4=0,B=0,C=0,D=0,E=0,F=0,10=0;09A3)
Indicates that Zones 0 and 3 are favorite, and Zones
4, 11 (Bh), 12 (Ch), 13 (Dh), 14 (Eh), 15 (Fh) and 16
(10h) are not attributed as favorite for preset 16 (10h)
Override Settings: (receiveID, S, O, identifier=value,...identifier=value; cs16)
The settings of the various RS-232 and BKC-DIP options are available in the System Settings.
The question arises, “How can the RS-232 and BKC-DIP options of the connected B&K
Components’ device be modified via RS-232 and BKC-DIP?” This dilemma can be addressed
using the Override Settings.
The Override Setting parameters mirror (or shadow) particular key System Setting parameters.
When the Override Settings are activated, by setting the Override Active parameter, the system
ignores various System Settings and uses the corresponding Override Settings instead. An
example will help clarify.
Suppose in a particular application it is required that the user be able to change the System Setting
parameters BKC-DIP Echo Enabled, Front Locked, and IR Locked (for a complete listing of
system parameter identifiers and maximum values see the complete listing in the product specific
Appendix B). However, simultaneously, the RS-232 application requires Echo commands to
verify proper transmission and regulate flow control while the front panel and IR commands
should be locked to assure the device under control does not respond to outside (non RS-232)
stimuli. The following command allow this:
(00, S, O, 0=1, 4=1, 6=1, 7=1, FF=A;04CE)
Dissecting the previous command reveals (see refer to the product specific Appendix P for details
regarding the Override Parameter values):
.. 0=1 .. Override Active is activated
.. 4=1 .. Override Echo Enabled is enabled
.. 6=1 .. Override Front Locked is locked
