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.

INSTALLATION
This section offers step-by-step instructions for installing the IN3055. A detailed application drawing showing all
equipment connections is included on the next page.
1. Turn the computer and computer monitor off. Disconnect the computer monitor (if present) from the
video output port on the computer.
2. The IN3055 utilizes a special loop-through input cable, the IN9041, which has a single male 15 pin
HD connector on one end and a double headed (male and female) connector on the loop-through end.
Connect the male side of the IN9041 loop-through input connector to the computer’s video output
port.
3. Connect the local computer monitor (if present) to the female side of the IN9041 loop-through
connector.
4. Connect the IN3055 amplified outputs to the various data displays’RGB analog inputs using the
appropriate high resolution coaxial cable such as the IN8000 Series or the IN9045. Unused outputs
do not need to be terminated.
5. Connect the round connector on the 9V power supply to the POWER input jack (located next to
Output #4). Connect the power adapter box side of the power supply to the A/C power source.
6. Complete the installation by turning the computer and computer monitor on.
INTERNAL JUMPERS
The IN3055 has three internal jumpers which affect the termination of the Red, Green, and Blue input
signals. In normal installations, the IN9041 loop-through input cable (included with the unit) should be
used on the input connector and either a local monitor or termination plug is attached to the female side
of the loop-through cable. Certain applications may call for the IN3055 to be installed without the
IN9041 loop-through input cable. In this case, the IN3055 internal jumpers should be set to provide a 75
ohm input termination as described below.
1. Remove power from the unit. Remove the two bottom case screws. Slide off the top cover.
2. Gently unplug the internal input cable by pulling up on the connector. Note the orientation of the
connector so you can return the cable to the same position after adjusting the jumpers.
3. Position jumpers JP1, JP2, and JP3 to terminated or unterminated as required:
Jumpers Open Red/Green/Blue Unterminated (Factory Default setting)
Jumpers Closed Red/Green/Blue Terminated to 75 ohms
4. Gently replug the input cable.
5. Replace the top cover and tighten the two bottom case screws.
Please note that these jumpers provide termination but no monitor emulation (ID bits).
If no local monitor is used, a termination plug must be installed on the female side of
the loop-through connector to provide the proper 75 ohm input termination. The
IN9031 15-pin HD VGA terminator plug (optional) provides 75 ohm termination for
the RGB signals and emulates a color VGA monitor.

TROUBLESHOOTING
A display device connected to one of the IN3055 outputs has a bad/scrambled image.
Solution 1: The display device connected to the distribution amplifier may not be compatible with the
computer’s video output. Many LCD panels and data monitors will not display signals at
resolutions higher than 640 x 480 and horizontal scan rates higher than 36 KHz. Make
sure you know what resolution mode the computer video card is set to output. Standard
VGA runs at 31.5 KHz, but SVGA can be as high as 48 - 58 KHz with newer modes such as
1600 x 1200 running at 79 KHz!
Solution 2: The output cable may have a bad sync line. Try another cable.
The output image is missing a color.
Solution: The output cable may be bad. Check both ends of the cable to see if any of the pins are bent
or missing. Also inspect the cable to see if the coax may have been pinched or severed
internally. Try another cable.
Output image is ghosting.
Solution: The IN3055 is designed to plug directly into the computer’s graphic card and a short
(6 to 12 ft) monitor cable attached to the loop-through (IN9041) output. An extension cable
for the input or a very long cable on the local monitor may cause this problem. The IN3055
must be located immediately adjacent to the source computer. Do not attempt to lengthen the
input cable.
The output image of the IN3055 is too bright/blooming.
Solution: There needs to be a termination on the loop-through output. Use a local monitor or an
IN9031 termination plug to provide the necessary 75 ohm termination.
When using the IN3055 with no local monitor, the computer output is black and white
when it should be color.
Solution: There needs to be a termination on the loop-through so that the computer video card will
configure itself for color VGA mode at boot-up. Use a local monitor or the IN9031
termination plug.
The output image of the IN3055 is visible but has poor quality / low definition.
Solution: The output cables may be too long or of poor quality. INLINE offers the IN8000 Series
High Resolution Mini-Coax cables in a variety of lengths. This type of cable can be used to
transmit VGA signals 75 to 100 feet or more depending on the signal scan rate.
When using the IN3055 with a laptop computer there is no output image.
Solution 1: An IN9031 termination plug should be used on the female side of the loop-through cable.
Solution 2: Many laptop computers (especially older units) require a keystroke combination in order to
activate the external VGA video port. Check the laptop owner’s manual.
