English Location and Function of Parts Features This DXC-190 color video camera is equipped with a 1/2type Exwave HAD™* (Exwave Hole-Accumulated Diode) CCD (Charge Coupled Device), and also has the following features: • High sensitivity (Minimum illumination: 0.8 lux, F 1.
qg Auto-iris lens selection switch (DC/VIDEO) Switch for selecting the control signal for the auto-iris lens. DC: For auto-iris lenses controlled by DC signals VIDEO: For auto-iris lenses controlled by video signals B qk ql Notes • When the DC/VIDEO switch is set to VIDEO, the backlight compensation function may not work properly. • When the DC/VIDEO switch is set to VIDEO, “hunting” may occur. If this occurs, use the LEVEL L/H adjustment screw on the lens to change the incident light level.
Installation Connections D Suitable lenses The lens must be either a C- or a CS-mount type of less than 1 kg. The protrusion behind the mounting surface must be within the following limits: 1 C-mount lens, 2 9 mm or less, 3 CS-mount lens, 4 4 mm or less Changing the plug on an auto-iris lens cable E The camera is supplied with a plug to fit the LENS connector. To connect an auto-iris lens, first replace the plug on the lens cable with the supplied plug. 1 Detach the old plug from the lens cable.
F Phase Adjustment 1 When using more than one camera, adjust the phase according to the following procedure. Horizontal phase (VS/VBS lock mode) The picture may shift horizontally when using an extended cable. Use the PHASE volume to adjust the horizontal phase. 4 CCD Characteristics The following conditions may be observed when using a CCD camera. They are not due to any fault within the camera. 3 Vertical smear This phenomenon occurs when viewing a very bright object.
