8.34. CGATE -- Query Camera Gating Status Information
This command is used to query the gating status of the microphone inputs . It is identical to the GATE command
except that any given microphone must be gated on for a specified hold time in order for it to be considered "on"
by the CGATE command. The command can be used to query the status of individual microphones, or the
wildcard character can be used to query the status of all the microphone inputs. A typical use for this command
is to control camera pointing based on microphone activity. The added hold time prevents the camera from
jumping too quickly between positions when there are short amounts of signal present.
The
CGATET specifies the hold time used for the gating decisions in this command. The CGATEEN can be used to
have gating information sent automatically instead of having to poll this command.
Example Description Status Message
F01CGATE3?
Query camera gating status of
microphone input 3 .
F01CGATE3x , , where x is 0 or 1 depending on whether
the input is gated off or gated on, respectively.
F01CGATE*?
Query camera gating status of all
microphone inputs.
F01CGATE*abcdefgh , where each letter (a, b, etc.) is
either 0 or 1 depending on whether the corresponding
microphone input is gated off or gated on, respectively.
8.35. CGATEEN -- Enable Automatic Camera Gating Messages
This command controls whether or not camera gating information messages are sent automatically. If CGATEEN
is enabled, then a CGATE*? query is performed each time the camera gating status of any microphone changes.
For example, if no microphones are currently gated on and CGATEEN is enabled, then if microphone input 3
gates on, the following status message will be automatically generated:
F01CGATE*00100000
See the
CGATE command for more information.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description Status Message
F01CGATEEN0
Disable automatic camera gating messages.
F01CGATEEN0
F01CGATEEN1
Enable automatic camera gating messages.
F01CGATEEN1
F01CGATEEN2
Toggle enabled state of automatic camera
gating messages.
F01CGATEENx , where x is either 0 or 1
depending on whether automatic camera gating
messages are currently disabled or enabled.
F01CGATEEN?
Query enabled state of automatic camera
gating messages.
F01CGATEENx , where x is either 0 or 1
depending on whether automatic camera gating
messages are currently disabled or enabled.
