Video-in
Before the
ELSA ERAZOR III can react, the signals must be clear. It is of no use if you try
to connect the antenna to the ELSA ERAZOR III. The antenna’s HF signal transmits infor-
mation for several channels, and not a simple, unambiguous video signal as required by
the
ELSA ERAZOR III. If you wish to display a TV picture on your monitor, then you cannot
simply take the antenna-output of your video recorder. Instead, the video recorder’s Scart
connector must be connected with the composite input of the
ELSA ERAZOR III.
Video-out
Unlike a computer monitor, a television set is not able to process the VGA signal from a
graphics board. Comparing the 15-pin output for the monitor with a coaxial antenna cable
makes it immediately clear that the signals are handled in fundamentally different ways.
The
ELSA ERAZOR III is equipped with its own translator, a chip which converts VGA sig-
nals for the television. This signal can of course be used by other devices such as projec-
tors with a video input or a video camera.
The right connection?
The video socket is on the mounting bracket of the ELSA ERAZOR III. Plug the composite
video adapter cable into this video socket (see page 36).
One for all: The composite video adapter cable

need: Video-in and video-out connections. First plug the wide connector with the VIDEO
