iris_setup <speed> <stepMode> <torque>
This command can be used to control the iris motor speed, step mode and torque. The
command works like the focus settings command in chapter 16.8.
16.13
iris_apt <aperture>
This command can be used to set the iris to a aperture position, or to determine the
current iris aperture. This command works only reliable if, the aperture/ position table (see
chapter 16.14) filled in correctly.

aperture
Iris aperture
The Range is defined by the min.
aperture and max. aperture in the
aperture/ position table.
The F-Stop value is multiplied with a
factor of 10, to avoid aperture values with
rational numbers.
Example:
# set the iris aperture to F-Stop 5.6:
iris_apt 56
# set the iris aperture to F-Stop 16:
iris_apt 160
# set the iris aperture to F-Stop 4.3:
iris_apt 43
16.14
iris_table <apt0> <pos0> ... <apt8> <pos8>
This command can be used to set the aperture/position table. This table is used to
determine the correct position of the iris in F-stops, if the user sends a
iris_apt
(see
chapter 16.13) command. The camera uses the given points of the table and uses a linear
interpolation between the given points.
Up to 9 aperture/position pairs can be given, at least one pair has to be specified
otherwise the command will fail. Unspecified pairs will be set to 0 which disables this table
entry.
