UT250-101
Under Table 8x4 VGA+Audio Matrix
Switcher with “Show Me” Keys+RS-232
Auto-Switcher
The UT250-101 is an 8x4 Video+Audio Matrix
Switcher designed to be mounted under a table as
part of an integrated audiovisual system. The
UT250-101 provides great flexibility for routing
multimedia signals from a single, convenient
location. Under Table solutions are ideal for
situations where it is too expensive or impractical to
install equipment directly into the furniture.
The UT250-101 accepts 8 computer/YPbPr video
inputs and 8 stereo inputs. The audio inputs accept
both left and right audio, and then combine them to
create a mono signal. The 4 video outputs function
as 2 independent dual outputs where any input can
be routed to 2 or all 4 of the video outputs. Each of
the 4 outputs can be switched independently using
RS-232 control. The audio output follows the last
switched input and delivers a balanced mono
output on both the left and right channels.
Input-to-output switching can be made from one or
all of the following methods: RS-232, contact
closures, auto-switching. RS-232 control is
accomplished from a computer or controller using
the RS-232 bus. Contact closures with LEDs
(“Show Me” keys) allow manual switching through
the Output Select Control inputs on the front of the
unit. These controls are designed for use with
momentary switches having built-in LEDs. Any
input can be switched to either, or both, of the dual
outputs and the LEDs show which connections are
active. The UT250-101 can also be configured for
auto-switching. In Auto-Switch mode, the
UT250-101 automatically switches to the lowest
number input with an active video signal applied.
Any selections made by a user from the Output
Select Control input override the Auto-Switch
feature.
In addition to standard video and audio outputs, the
UT250-101 also has a 4TP (4 Twisted Pair) output
for each video output. These 4TP outputs can be
used with a compatible Twisted Pair receiver, like
the TP115-111, to transmit the video and audio
signals over long distances to remote projectors or
other multimedia presentation systems.
The latest generation of Twisted Pair devices uses
an innovative, patented technology* developed by
ALTINEX. The new signal processing technology
allows transmitting and receiving fully equalized
computer video signals, stereo, and audio signals
over long distances.
