Hardware Customization

The camera head is delivered in a ready-to-use state,
however, there are occasions when it might be
necessary to re-adjust some functions after, for
example, fitting a new lens.
A large number of functions can be set-up using the
control facilities of the menu system. In addition to this
software set-up there are some functions which can be
selected or adjusted internally in the camera.
Refer to the next chapters for instructions.

When a camera is supplied with a lens it is not
necessary to perform any of the following adjustments
as the lens is already matched to the camera. However,
if you wish to change to a different type of lens or the
lens is not supplied with your camera, back focus,
white shading and auto iris adjustment procedures
may have to be performed.
• Colour balance.
If required, perform the gain adjustment of the
preprocessor board and/or white shading adjustment
procedures, described in section 3.
• Auto Iris Adjustment
If a different lens either works too slow or overshoots
too much with the auto iris control, adjust the
potentiometer on the lens to obtain acceptable
operation. Refer to the lens documentation.
• Back Focus Adjustment
To adjust the back focus of the lens refer to the
documentation of the lens.
