MANUFACTURERS DECLARATION OF CONFORMANCE
The manufacturer declares that the equipment supplied with this manual is compliant with the essential protection requirements
of the EMC directive 89/336 and the Low Voltage Directive LVD 73/23 EEC. Conforming to the requirements of standards EN 55022

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.
Lens Level Adustment
If the camera is used with a direct drive (DD) lens this potentiometer varies the DC 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.
Composite 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 VIDEO OUT.
Supply Terminals
These terminals accept a power supply of 12 VDC ±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 DC lenses, the EI must be
OFF
. See also Lens Level
Adjustment. The default setting is
