The A-minima video assist
This on-board flicker less video assist has been designed to integrate
a reliable B & W CCD video camera without compromising the A-
minima size, flexibility and ease of use.
Powered internally from the A-minima camera body, it does not
need an outside power cable. Nevertheless, it is recommended to
power it using the Aaton power base installed on the A-minima
body, not from the internal disposable batteries.
The A-minima video assist has two separate video outputs. One is a
standard BNC connector, the other one is a small Fisher4 connector
used for a small mini LCD monitor. This connector carries 12V,
ground and composite video.
The video assist also features a main on/off switch, a small running
LED and manual lens iris control.
As standard from the factory The A-minima camera is equipped
with an internal 75/25 beamsplitter. This means that 25% of the
light from the viewfinder is sent to the CCD target.
Installing the video assist.
You should not usually have to do this operation. The video assist is
designed to stay with the camera body. as it does not add excessive
weight.
However, in some instances, you might need to do it. Please follow
this procedure when installing the video assist on the camera.
Unscrew the video port cover located above the camera motor, on
the control panel side, and pull out the wire bundle used to power
the video assist.
Through the hole located on the upper left corner of the camera lens
port, carefully loosen the tightening screw used to later hold the
video lens onto the camera internal tubular holder.
Do not unscrew it completely as it could fall into the camera hous-
ing. two or three turn will suffice.
