Camera/Lens Adjustments
After all cabling is complete, the camera and lens can be adjusted.
DIP Switch Settings
On color cameras, line lock and autoiris control are DIP switch selectable. For monochrome cameras, only
autoiris control is available. AI setting is for external autoiris and EE setting is for internal autoiris. Refer to
Figure 6 for the location and setting of the switches. To obtain the sharpest picture possible, the iris adjustment
should be made from a “full bright” setting down to an acceptable video level. This assures that the internal AGC
of the camera is not operational. On monochrome cameras, there is a 2-pole DIP switch. Only switch 2 is
functional, which allows the selection of internal autoiris (left position) or external autoiris (right position). Do not
adjust this DIP switch if using a manual lens.
Lens/Autoiris Adjustment
The lens can be manually adjusted for iris, focus and angle of view. On the lens, focus (near to infinity) is the
front ring, the telephoto/wide adjustment is the middle ring and iris (open and close) is the end ring. On autoiris
lenses, iris adjustment may be required if the picture appears dark or grainy or has poor color. There is a
potentiometer (VR3 on monochrome cameras, VR1 on color cameras) on the camera board to adjust the
autoiris. Refer to Figures 4 and 6. Turning the potentiometer opens and closes the iris to regulate light extremes.
Turning the potentiometer clockwise opens the iris wider, allowing more light.
