IN3055 OPERATION MANUAL - REV. 2.1 02/19/00
DESCRIPTION
The IN3055 is a dedicated VGA video distribution amplifier. The unit features a high impedance loop-
through output and four buffered outputs, a design which allows for the simultaneous viewing of a local
monitor and up to four additional output devices such as monitors, LCD projectors, and other compatible
display devices. The IN3055 does not alter the video or sync signals, but merely amplifies the signals to
a level needed to extend the external displays as far as 100 feet away. The IN3055 distribution amplifier
is fully automatic, offering easy operation and the following features:
♦
Loop-through Input Cable allows the local computer monitor to continue operating while feeding
an input signal to the IN3055
♦
Four buffered outputs - connectors and sync format are identical to the input (standard VGA pin
outs), ideal for use with multiple VGA monitors, LCD panels, and other display devices
♦
Gain of 1.1 provides signal boost to compensate for 75 to 100 feet of high resolution coaxial cable
♦
100 MHz bandwidth
INPUT COMPATIBILITY
The IN3055 VGA distribution amplifier operates with analog video input from a wide variety of IBM
and compatible computer video signal formats including VGA, SVGA, XGA, and 8514A. Input signals
to the IN3055 must be in the RGBHV format and provided on a 15 pin HD connector.
OUTPUT COMPATIBILITY
The IN3055 offers four buffered video output signals in the same format and using the same connector as
the original input signal. This is ideal for use with devices such as LCD panels, which often must see a
specific type of connector and sync format in order to recognize and lock up to various frequencies.
VGA, SVGA, and XGA type video cards operate in several different modes encompassing a wide range
of resolutions and horizontal scan rates. The IN3055 is not a scan converter and the data projector or
data monitor must be compatible with the horizontal scan rate put out by the computer video card.
Please check the documentation for both the computer video card and the data projection device in order
to ensure compatibility.
It is very important that all input / output connections be made utilizing high
resolution coaxial cables such as the IN8000 Series. Proper cable selection is
critical to overall system performance, especially when working with high frequency
signals and/or long cable runs.
