8.3.41 Iris Control Interval
Function Command String Camera Response
Set Iris Control Interval :ICI=[DDD]<cr> :o<cr>
Set the Iris Control Interval. [DDD] is the interval value with a
range of 1 – 500 msec. This value determines the amount of
time the iris control motor is pulsed during the IRI (Iris
Increment) and IRD (Iris Decrement) commands.
Get Iris Control Interval
:ICI?<cr> :oICI[DDD]<cr>
Enquire current Iris Control Interval value. [DDD] is the
current value with a range of 1 – 500 msec.
8.3.42 Impulse Filter
Function Command String Camera Response
Set Impulse Filter
:IFC=[DD]<cr> :o<cr>
Set the IFC value (impulse filter control for ALC). [DD] is the
level value with a range of 1-100. This command applies only
to camera models TM-770.
Get Impulse Filter
:IFC?<cr> :oIFC[DD]<cr>
Enquire current IFC value (impulse filter for ALC). [DD] is the
current value with a range of 1-100. This command applies
only to camera models TM-770.
8.3.43 Iris Control
Function Command String Camera Response
Set Iris Control :IRC=[DDD]<cr> :o<cr>
Set the Iris Control. [DDD] is the current value with a range of
0 to 127 for a voltage range of 0-9 V. Therefore there are
0.141 V/count.
Get Iris Control
:IRC?<cr> :oIRC[DDD]<cr>
Enquire current Iris Control value. . [DDD] is the current value
with a range of 0 to 127 for a voltage range of 0-9 V.
8.3.44 Iris Decrement
Function Command String Camera Response
Iris Decrement
:IRD=[DDD]<cr> :o<cr>
Decrement the iris control by DDD% of full scale. [DDD] is the
percent of full scale to decrement the iris to with a range of 1
- 100. The iris control motor will be pulsed with a negative
voltage equal to DDD% of full scale for the duration specified
by the ICI (Iris Control Interval) command and then returned to
a neutral position.
Note: This command will cause the Iris Control Value (IRC) 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 iris motor is returned to
the neutral position (0) after the decrement action is
complete.
