8.3.104 Zoom Decrement
Function Command String Camera Response
Zoom Decrement :ZMD=[DDD]<cr> :o<cr>
Decrement the zoom control by DDD% of full scale. [DDD] is
the percent of full scale to decrement the zoom to with a
range of 1 - 100. The zoom control motor will be pulsed with a
negative voltage equal to DDD% of full scale for the duration
specified by the ZCI (Zoom Control Interval) command and
then returned to a neutral position.
Note: This command will cause the Zoom Control Value (ZMC)
to change. The user is responsible for querying the camera for
the current value after this command is executed. The
expected value is zero because the zoom motor is returned to
the neutral position (0) after the decrement action is
complete.
8.3.105 Zoom Increment
Function Command String Camera Response
Zoom Increment :ZMI=[DDD]<cr> :o<cr>
Increment the zoom control by DDD% of full scale. [DDD] is the
percent of full scale to increment the zoom to with a range of
1 - 100. The zoom control motor will be pulsed with a voltage
equal to DDD% of full scale for the duration specified by the
ZCI (Zoom Control Interval) command and then returned to a
neutral position.
Note: This command will cause the Zoom Control Value (ZMC)
to change. The user is responsible for querying the camera for
the current value after this command is executed. The
expected value is zero because the zoom motor is returned to
the neutral position (0) after the decrement action is
complete.
8.3.106 Zoom Neutral
Function Command String Camera Response
Zoom Neutral :ZMN!<cr> :o<cr>
This command turns off the zoom motor and is equivalent to
the ZMC=0 command.
Note: This command will cause the Zoom Control Value (ZMC)
to change. The user is responsible for querying the camera for
the current value after this command is executed. The
expected value is zero because the zoom motor is set to the
neutral position (0).
