8.36. BUSREF -- Set Which AEC Reference is Placed on EF Bus

This command sets or queries whic AEC reference (if any) is placed on the EF Bus. Setting BUSREF to '0'
means that no reference is placed on the EF Bus. Setting BUSREF to '1' means that AEC reference 1 (R1) is
placed on the bus. Setting BUSREF to '2' means that AEC reference 2 (R2) is placed on the bus.
The AEC references are created in the main matrix via outputs R1 and R2.
Only one Vortex can put a reference on the EF Bus at a time. If more than one Vortex places its reference on
the EF Bus, then an 'ERROR#093' will occur.
This command is an integer command. See
minimum and maximum values for this command are 0 and 2, respectively.
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
B01BUSREF2 Put AEC Reference 2 (R2) on the EF Bus.
Set Vortex to not place any AEC reference
B01BUSREF0
on the EF Bus.
Query which AEC reference this Vortex is
B01BUSREF?
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 inputs . 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. 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 specifies the hold time used for the gating decisions in this command. The
CGATET
used to have gating information sent automatically instead of having to poll this command.
Example Description
Query camera gating status of
B01CGATE3?
microphone input 3 .
Query camera gating status of all
B01CGATE*?
microphone inputs.

Status Message
B01BUSREF2
B01BUSREF0
B01BUSREFx , where x is 0, 1, or 2
depending on which AEC reference (if any) is
currently being placed on EF Bus.
Status Message
B01CGATE3x, , where x is 0 or 1 depending on
whether the input is gated off or gated on,
respectively.
B01CGATE*abcd , 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.
