Cgate -- Query Camera Gating Status Information; Cgateen -- Enable Automatic Camera Gating Messages - Polycom Vortex EF2211 Programming Manual

Example Description
Put AEC Reference 1 (R1) on the EF Bus.
Set Vortex to not place any AEC reference on
the EF Bus.
Query which AEC reference this Vortex is
S01BUSREF?
placing on the EF Bus.

8.37. CGATE -- Query Camera Gating Status Information

This command is used to query the gating status of the microphone input. It is identical to the
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. 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 specifies the hold time used for the gating decisions in this command. The
CGATET
be used to have gating information sent automatically instead of having to poll this command.
Example Description
Query camera gating status of
S01CGATE1?
microphone input 1.
Query camera gating status of all
S01CGATE*?
microphone inputs.
8.38. 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 the microphone is currently gated off and CGATEEN is enabled, then if the microphone
gates on, the following status message will be automatically generated:
S01CGATE*1
See the command for more information.
CGATE
This command is a boolean command. See
Status Message
, where x is 0 or 1 depending on
which AEC reference (if any) is
currently being placed on EF Bus.
Status Message
, , S01CGATE1x where x is 0 or 1
depending on whether the input is gated off
or gated on, respectively.
S01CGATE*x , where x is either 0 or 1
depending on whether the corresponding
microphone input is gated off or gated on,
respectively.
