Default switch positions shown (white represents switch position)
(1) Synchronisation Selection (LL/INT)
This switch is used to select the camera synchronisation modeꢀ When the camera is connected
to anAC supply the Line-lock (LL) mode can be usedꢀ This locks the camera frame rate to the
mains frequency so that cameras in a system are triggered at the same point on the mainsAC
cycleꢀAlso see 5, 6 and 7 Line Lock PhaseAdjustmentꢀ
(2) Backlight Compensation (BLC)
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 silhouetteꢀ Select ON
or OFF using the BLC switchꢀ Default is OFFꢀ BLC will only function with a manual iris lens when
the Electronic Iris facility is switched onꢀ For direct drive and auto iris lenses, BLC will still
function even though the Electronic Iris facility is switched offꢀ

(4) Electronic Iris (EI)
CONTROLS AND SWITCHES
The Electronic Iris (EI) compensates for excessive light level by automatically adjusting the
shutter speedꢀ The electronic iris should be ON when using fixed or manual iris lensesꢀ When
usingAuto Iris (AI) lenses of either the video drive or DC drive types the EI must be OFFꢀAlso
see (10) Electronic Iris and DC Lens LevelAdjustment Potentiometerꢀ
(5) Line Lock Phase Adjust Potentiometer
When the camera is in line-lock mode it is possible to adjust the point on theAC cycle at which
the camera triggersꢀ This facility is provided so that cameras that are connected to different
mains phases may still be synchronisedꢀ
The line lock phase adjustment potentiometer allows the line lock phase trigger point to be
adjusted by ±120Oꢀ Rotating the potentiometer clockwise advances the trigger point and turning
it anticlockwise retards the trigger pointꢀ The factory default setting is the zero crossing pointꢀ
If all cameras in a system are on the same mains phase then no line lock phase adjustment
should be madeꢀ
(6 and 7) Line Lock Phase Adjust Buttons (+ Advance; - Retard)
When the camera is in line-lock mode it is possible to adjust the point on theAC cycle at which
the camera triggersꢀ This facility is provided so that cameras that are connected to different
mains phases may still be synchronisedꢀ
The line lock phase adjustment buttons allows the line lock phase trigger point to be adjusted by
±120Oꢀ Pressing the advance button advances the trigger point and pressing the retard button
retards the trigger pointꢀ The factory default setting is the zero crossing pointꢀ If all cameras in
a system are on the same mains phase then no line lock phase adjustment should be madeꢀ
