DA1957CT
CAT-5 DISTRIBUTION AMPLIFER
The DA1957CT is a 1-in 4-out CAT-5 distribution
amplifier designed to connect a single Altinex
CAT-5 Transmitter to as many as four Altinex
CAT-5 Receivers. The DA1957CT will pass
computer video and audio signals from the
transmitter over twisted pair (RJ-45) type cable.
A typical setup allows a single computer's video
and audio sources to be connected to up to four
CAT-5 receivers. In turn, each receiver connects to
a video monitor, projector etc… and/or an audio
device such as speakers or an amplifier.
Altinex compatible transmitters and receivers
include the DA1930CT VGA+AUDIO to CAT5
Transmitter and the DA1931CT VGA+AUDIO
CAT-5 Receiver.
The DA1957CT is capable of equalizing the
attenuation effects of long cable runs up to 400 feet
depending upon the type and quality of cable being
used. Additionally, there is a Signal Detect feature
which shows when an input signal is present.
