Example

S01BUSREF?

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 placing on the EF Bus.

Status Message

,where x is 0 or 1 depending on which AEC reference (if any) is currently being placed on 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 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. 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

S01CGATE1?

S01CGATE*?

Query camera gating status of microphone input 1.

Query camera gating status of all microphone inputs.

,, 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.

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 CGATE command for more information.

This command is a boolean command. See Section 6.1 for more information on this type of command.
