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.
