8.52. GATE -- Query Gating Status Information
This command is used to query the gating status of the microphone inputs. 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.
The
GATEEN can be used to have gating information sent automatically instead of having to poll this command.
Also see the
CGATE command, which only reports microphones that have been gated on for a specified hold
time.
Example Description Status Message
F01GATE3?
Query gating status of microphone
input 3 .
F01GATE3x , where x is 0 or 1 depending on whether the
input is gated off or gated on, respectively.
F01GATE*?
Query gating status of all
microphone inputs.
F01GATE*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.
8.53. GATEEN -- Enable Automatic Gating Messages
This command controls whether or not gating information messages are sent automatically. If GATEEN is
enabled, then a GATE*? query is performed each time the gating status of any microphone changes. For
example, if no microphones are currently gated on and GATEEN is enabled, then if microphone input 3 gates on,
the following status message will be automatically generated:
F01GATE*00100000
See the
GATE command for more information.
