CONTROLS AND SWITCHES
The diagram below shows the locations and functions of the controls and switches.
Mounting Bolt
Two 1/4 20 UNC mounting bolts are provided for mounting the camera, one on the the top of the case and one on the bottom of
the case.
Len Level Adu tment
If the camera is used with a direct drive ( ) lens this potentiometer varies the C reference voltage used to control the lens. The
potentiometer has the effect of increasing or decreasing the lens aperture. This potentiometer should be adjusted to obtain a 1V
pk-pk video output and is therefore the factory setting.
Compo ite Video
To obtain a 1.0V [pk-pk] composite video signal, connect a video coaxial cable terminated with a 75 Ohm BNC connector to the BNC
socket marked VI EO OUT.
Supply Terminal
These terminals accept a power supply of 12 V C ±10%, ripple less than 200mV.
EI on/off
The Electronic Iris (EI) compensates for excessive light level by automatically adjusting the shutter speed. The electronic iris
should be ON when using fixed or manual iris lenses. When using Auto Iris C lenses, the EI must be OFF. See also Lens Level
Adjustment. The default setting is ON.

The BLC (Back Light Compensation) facility compensates for back-lit scenes by enhancing objects in the centre of the scene
which would previously have been in silhouette. Select ON or OFF using the BLC switch. efault is OFF. BLC will only function with
a manual iris lens when the Electronic Iris facility is switched on. For direct drive lenses, BLC will still function even though the
Electronic Iris facility is switched off.
DD/AI Len Connector
This 4-pin connector supplies the power and C control signal for use with irect rive Auto Iris lenses. If the lens does not have
a plug fitted then wire the lens to a suitable plug in accordance with the diagram below:

LENSES
VC200 series cameras are suitable for CS mount lenses in fixed iris, manual iris or direct drive C versions. The camera has a
mechanism for adjusting the distance from the back of the lens to the CC sensor. To adjust, use a suitable tool to loosen the
focus locking screw, then rotate the focus adjustment ring either clockwise or anticlockwise as required. Tighten the focus locking
screw when adjustment is satisfactory.
