DESCRIPTION
The IN3252HR is a one input, two output distribution amplifier / line driver designed to split a single
RGBHV signal to two data monitors, data projectors, or other RGBHV compatible output devices.
Capable of increasing signal voltage by up to 40%, the IN3252HR also functions as a line driver,
allowing video signals to be sent down longer cables that would be possible without a line driver. Actual
maximum drive distance depends on the resolution of the video signal and is largely determined by the
bandwidth of the cable used for input and output connections.
PRODUCT FEATURES
•Two Buffered Outputs – Allows the signal from one RGBHV source to drive two displays.
•600 MHz Video Bandwidth – Provides superb video performance and compatibility with ultra-high
resolution video signals from graphic workstations.
•External Gain Controls – Individual gain controls for Red, Green and Blue Signals. Permits
accurate adjustment of gray scale and increases signal voltage to drive long cable runs.
•Sharpness Control -- Enhances high resoution video signals. Provides improved image clarity and
boosts visibility of fine details.
•BNC input and output connectors
•Wide Compatibility – Compatible with RGBHV, RGBS, RGsB, RsGsBs, Component, Y/C, High
Resolution Monochrome Video and Composite Video Baseband Signals.
•Loop Output – Provides passive loop-through signal which can drive additional amplifiers to create
a larger DA system or drive a local monitor.
•Metal case enclosure
•Optional Mounting Brackets
COMPATIBILITY
The IN3252HR will operate with RGBHV, RGBS, RGsB, and RsGsBs analog video input signals. When
amplifying RGsB signals (sync on green) and RsGsBs signals (sync on all) only use the red, green, and
blue channels (i.e.: leave the sync channels open.) The red, green, and blue channels may also be used to
amplify or split composite NTSC video signals.
INSTALLATION
1. If operating the IN3252HR without loop output (factory default,) begin with step 2. If operating the
IN3252HR with the loop output connector, please refer to INTERNAL CONTROLS section on
page 3 and set jumpers as appropriate.
2. Connect the red, green, blue, and sync signals from the source to the input of the IN3252HR (see the
Compatibility section for details on Sync on Green and Sync on All signals.)
3. Connect output red, green, blue and sync signals to the display devices or other equipment.
When distributing higher scan rate signals over long cable lengths, cable choice is very critical to
overall system performance. The IN7000-5 / IN7100-5 / IN7200-5 Series High Resolution
RGBHV cables are available in a variety of lengths and are well suited for this purpose.
4. Connect power by plugging in the power supply.
5. Adjust gain and sharpness controls if required (see OPERATION section for details.)

IN3252HR OPERATION MANUAL - REV. 1 12/01/98 ©1997 - INLINE, INC.
OPERATION
The IN3252HR has external gain / sharpness controls and internal jumpers which may be used to
customize the IN3252HR for specific needs (see diagram on page 3.) While the internal controls need
not be changed from the factory default settings for most installations, this section describes how to
change the jumper settings for unique applications. For all jumper settings in this section, orient the unit
so the RGBHV / POWER input side is facing towards you and the output side is facing away.
GAIN AND SHARPNESS CONTROLS
The gain controls may be used to adjust the Red, Green, and Blue output signal voltage over a gain range
of 0.7 to 1.4. These controls may be used to calibrate the color balance or to increase the signal voltage,
compensating for signal losses due to long cable runs. Sharpness may be used to reboost high frequency
components that have been attenuated by long cable runs. The sharpness control employs an equalization
circuit, introducing an adjustable high frequency peak.
Gain Control
The gain control is used to increase/decrease the contrast of an image by adjusting the amplitude of the
video signal. The control has a range of 0.7 to 1.4. Using the IN9333 adjustment tool, gently turn the
control clockwise to increase the video gain, and counter-clockwise to decrease the gain.
Sharpness Control
The sharpness control enhances image detail and sharpness by boosting high frequencies. This control is
optimized for signal frequencies of 30 KHz and higher. There is little visible effect for lower scan rate
signals such as NTSC/PAL. Using the IN9333 adjustment tool, gently turn the control clockwise to
increase peaking, and counter-clockwise to decrease the peaking.
LOOP OUTPUT CONNECTOR
The loop output connector provides a passive loop-through signal. This can be looped through to
additional amplifiers to create a larger DA system or to drive a local monitor. In order to use the loop
output, the Input termination jumpers (internal) must be set to High Z (unterminated.) The locations of
the input termination jumpers are indicated on page 3. If you are driving a local monitor, be sure to keep
the cable shorter than 12 feet in order to prevent reflections.
INTERNAL CONTROLS
CAUTION: Adjustment of the IN3252HR internal controls must only be carried out by qualified
technicians. Care must be taken to avoid static shock to the internal components. Power must be
removed from the unit before making any jumper changes.
The IN3252HR has internal jumpers which can be accessed using the following procedure:
1. Remove power from the unit.
2. Remove the screws from the sides of the unit and slide the top cover off.
3. Identify location of jumpers using the diagram on page 3 and adjust as needed.
4. Replace top cover and tighten screws.

TROUBLESHOOTING
Problem: There is no image displayed on the projector. The output of the IN3252HR doesn’t
seem to work.
Suggestions:
qVerify that the signal from the graphics source is compatible with the projection
device by connecting them directly (bypass the IN3252HR.)
qCheck to make sure the sync cables are good. Try sending the sync signals on
different cables.
qCheck the power supply. If the power supply is receiving power and working
properly it should feel slightly warm to the touch after it has been plugged in for half
an hour. If the power supply feels cool to the touch you may have either a faulty A/C
power source or a bad power supply.
Problem: One of the colors is completely missing from the projected image.
Suggestion:
qVerify that the input and output cables are good. Bypass the missing color signal
around the IN3252HR, joining the input and output cable for that one color together
with a BNC barrel. If the problem goes away, the IN3252HR may be faulty. If the
problem persists, one of the input/output cables or the graphics source is faulty.
Problem: The colors are not displayed properly on the projector/monitor.
Suggestions:
qVerify that all RGB connections are correct and that none of the colors are swapped.
qThe IN3252HR gain controls may be misadjusted. Begin by setting the three gain
controls to a similar position.
qBypass the IN3252HR. If the problem persists, the data projector may have the
video drive levels on the CRTs misadjusted. Re-calibrate the Red, Green, and Blue
drive levels.
Problem: The projected image is far too “hot,” appearing excessively white and washed-out.
Suggestions:
qBypass the IN3252HR. If the image looks better, the IN3252HR RGB gain controls
may be set too high. Reinstall the IN3252HR into the signal path and reset the gain
controls to a lower level. If the problem persists after the IN3252HR is removed try
the following suggestions.
qCheck the termination switches on the monitor or video projector. The termination
switches should be set to "75 Ohm Termination" unless the signal is being looped to
another display device.
qCheck the brightness and contrast settings on the projector or monitor. Many CRT
type devices look best when the contrast is set towards the upper end of the
adjustment range (80% - 95%) and the brightness is set in the middle of the
adjustment range (40 - 65%).
qThe input termination may be set to High Z. Check the termination jumper settings
(see page 3.)

IN3252HR OPERATION MANUAL - REV. 1 12/01/98 ©1997 - INLINE, INC.
Problem: The IN3252HR is being used to drive / split five separate composite video signals. The
three signals on the Red, Green, and Blue are working well, but the H & V Sync
connectors don’t seem to pass the other two video signals
Suggestion:
qWhile it is perfectly fine to use the Red, Green, and Blue channels to drive or split
composite video signals, the Sync channels are designed to work with digital sync
signals and will not properly amplify analog video signals.
Problem: The loop output is not working.
Suggestion:
qThe input termination for input 1 must be set to High Z. Set the internal jumpers as
shown on page 3.
