A HDS4.2 Overview
A Description of the HDS4.2
The HDS4.2 is a 4 input, Audio / HDTV Video switch. It supplies two HDTV Component Video out-
puts. Output 1 (labelled:
OUT1
) is a passive non-buffered output, and Output 2 (labelled:
OUT2
) is
a buffered version of
OUT1
.
OUT2
is always a buffered version of
OUT1
and cannot be switched
independently.
OUT1
is passive and is usually used to drive a HDTV component located near the HDS4.2, using
short cables.
OUT2
is buffered and can be used to drive much longer lengths of cables, such as
those needed to drive an, across the room, projector.
Included are three 75 ohm, RCA jack, terminators. Since the
OUT1
is the output of a passive switch,
it relies upon the HDTV to terminate the signals. In cases where
OUT1
is not used, such as using
only
OUT2
to drive a projector, located across the room,
OUT1
must be terminated for proper op-
erations. Whenever
OUT1
is left unused, the three supplied 75 ohm terminators must be plugged
into the
OUT1
RCA jacks.
Channel selection can be done using front panel switches, or by using any, user supplied, standard
IR remote control.
Also available is an optional RS-232 module allowing extended control of the HDS4.2 using a stan-
dard serial port. The RS-232 module must be purchased separately.
