Focus Control
Function
Command String
Camera Response
Set Focus Control
:FOC=[DDD]<cr> :o<cr>
Set the Focus Control. [DDD] is the focus value with a range of
-127 - +127 for a voltage range of 0-9 V.
Therefore there are
0.14.1 count/V.
Get Focus Control
:FOC?<cr> :oFOC[DDD]<cr>
Enquire current Focus Control value. [DDD] is the focus value
with a range of -127 - +127 for a voltage range of 0-9 V.
Therefore there are 0.14.1 count/V.
8.3.37
Focus Decrement
Function
Command String
Camera Response
Focus Decrement
:FOD=[DDD]<cr> :o<cr>
Decrement the focus control by DDD% of full scale. [DDD] is
the percent of full scale to decrement the focus to with a
range of 1 - 100. The focus control motor will be pulsed with a
negative voltage equal to DDD% of full scale for the duration
specified by the FCI (Focus Control Interval) command and
then returned to a neutral position.
Note: This command will cause the Focus Control Value (FOC)
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 focus motor is returned to
the neutral position (0) after the decrement action is
complete.
8.3.38
Focus Increment
Function
Command String
Camera Response
Focus Increment
:FOI=[DDD]<cr> :o<cr>
Increment the focus 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 focus control motor will be pulsed with a voltage
equal to DDD% of full scale for the duration specified by the
FCI (Focus Control Interval) command and then returned to a
neutral position.
Note: This command will cause the Focus Control Value (FOC)
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 focus motor is returned to
the neutral position (0) after the decrement action is
complete.
8.3.39
Focus Neutral
Function
Command String
Camera Response
Focus Neutral
:FON!<cr> :o<cr>
This command turns off the focus control motor and is
equivalent to the FOC=0 command.
Note: This command will cause the Focus Control Value (FOC)
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 focus motor is set to the
neutral position (0).
