CONTROLS AND SWITCHES
BLC on/off
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. Default 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 Lens Connector
This 4-pin connector supplies the power and DC control signal for use with Direct Drive Auto Iris lenses. If the lens does not have
a DD 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 DC versions. The camera has a
mechanism for adjusting the distance from the back of the lens to the CCD 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.
