Mount the lens according to the procedures described below.
1.
Before mounting a lens, check whether
it is a C-mount or CS-mount lens.
To change the mounting method, loosen
the back-focus locking screw (M 2.6)
using a Phillips head screwdriver, turn
the back-focus adjusting ring with your
fingers or the screwdriver and change
the mounting method.
As regards the dimension (b) of the area
to which the lens is to be installed as
illustrated on the left diagram, use the
one with less value than what’s shown
in the table below.
For both the C-mount and CS-mount,
never use whatever exceeds the dimen-
sion (b), as such will not allow normal
installation and damage the inner part
of the camera, resulting in a malfunc-
tion.
The F mark indicates a focal point.
2.
Mount the lens on the camera by turning
the lens clockwise. Adjust its position.
3.
When using an auto-iris lens with an EE
amplifier, turn the switch to the “VIDEO”
side. When no EE amplifier is equipped,
turn the switch to the “DC” side.
4.
If the lens has an auto-iris mechanism,
connect the lens cable after checking the
pin arrangement.
If the lens cable has a different type of
plug, use the 4-P plug supplied.
