Product Overview
The IN3264 / IN3268 is a high-resolution dedicated VGA distribution amplifier designed to amplify
and split the VGA / SVGA / XGA signal from a single computer video card to four or eight data grade
displays such as data monitors, LCD projectors, presentation monitors, graphics projectors or other output
devices. The IN3264 / IN3268 features 15-Pin HD connectors for input and outputs, allowing for direct
connection to VGA-type video sources and displays using high-resolution coaxial VGA extension cables
such as the IN8000 series.
The units are identical except for the number of outputs and the number of sharpness controls:
The IN3264 has four buffered outputs and one sharpness control.
The IN3268 has eight buffered outputs and two sharpness controls.
FEATURES
Universal VGA Signal Compatibility - While the IN3264 / IN3268 is primarily designed for VGA-
type video cards and monitors, this distribution amplifier’s six discreet amplification paths make it capable
of amplifying analog video signals in a variety of sync formats including RGBHV, RGBS, RGsB, and
RGBHVS. The IN3264 / IN3268 can connect to MAC, SUN, SGI and other high-resolution workstations
and monitors by using input and output adapter cables (see list on page 7).
Ultra High-resolution Amplification - Featuring 300 MHz video bandwidth and four or eight
buffered outputs, the IN3264 / IN3268 provides excellent video performance, ensuring maximum image
clarity with VGA-type and other analog video signals at virtually any resolution.
Sync Format / Polarity Preservation - Some display devices depend on receiving VGA, MAC, SUN,
SGI and other signals in their original sync format with unchanged sync polarity to ensure proper
operation. The IN3264 / IN3268 output signals have the same sync format and polarity as the input signal,
ensuring excellent operation with a wide range of compatible CRT, LCD, DMD, and Plasma Data Display
devices.
Buffered Outputs - The IN3264 / IN3268 features four or eight buffered outputs and provides the
amplification necessary to extend data displays 100 feet or greater from the source computer when used
with high-resolution coaxial cables. Maximum drive distance is dependent on both the input signal
resolution and the quality of the output cables. The IN8000 Series VGA extension cables (available in
various lengths from 6’ to 100’) are specifically designed for this purpose.
A Sharpness Control provides effective image enhancement for high-resolution video signals by
increasing clarity and edge detail. Monitor Emulation Dip Switches located on the bottom of the units
engage emulation for a VGA color monitor or MAC 13" / 14" RGB monitor. Two IN3264 or IN3268
amplifiers may be rack mounted side-by-side in a 1U rack space using the optional IN9080 rack shelf.

INPUT / OUTPUT COMPATIBILITY
VGA / SVGA / XGA Compatibility - The unit features 15-pin HD VGA-type connectors for input
and outputs. The units will directly connect to VGA video cards and display devices using the IN8000
Series of VGA extension cables, available in a variety of lengths from 3’to 100’. Longer lengths are
available by custom order.
MAC / SUN / SGI / Workstation Compatibility - While the IN3264 / IN3268 is primarily designed
for VGA-type video cards and monitors, this distribution amplifier actually has 6 discrete amplification
paths and is capable of amplifying analog video signals in a variety of sync formats including RGBHV,
RGBS, RGsB, and RGBHVS. The IN3264 / IN3268 can connect to MAC, SUN, SGI and other high-
resolution workstations and monitors by using input and output adapter cables (see list on page 7).
VGA, SVGA, XGA, SUN, SGI and other workstation video cards operate in
several different modes encompassing a wide range of resolutions and
horizontal and vertical scan rates. The IN3264 / IN3268 is not a scan
converter and the display devices attached to the outputs must be compatible
with the resolution, horizontal scan rate and vertical refresh rate output of
computer video card. Please check the documentation for both the computer
video card and the data projection device in order to ensure compatibility.
Installation
This section offers step-by-step instructions for installing the IN3264 / IN3268.
1. Turn the computer and computer monitor off. Disconnect the computer monitor (if present) from the
video output port on the computer.
2. Connect an input cable between the computer video port and the IN3264 / IN3268 input using the
appropriate cable as indicated in the chart on Page 7.
3. Connect the local computer monitor (if present) to Output #1 on the IN3264 / IN3268 distribution
amplifier. VGA local monitors can be connected directly to the output. Other types of local monitors
are connected using the appropriate adapter / extension output as indicated in the chart on Page 7. If no
local monitor is connected to Output #1, you can emulate a VGA color monitor / MAC 13" RGB
monitor using the dip switch located on the bottom of the unit.
4. Connect output devices (monitors, data projectors, etc.) to the other IN3264 / IN3268 output
connectors. Devices may be connected directly to the outputs, or you may use the appropriate adapter
/ extension output cables as indicated in the chart on Page 7. For best results, high-resolution coaxial
cables are recommended for all output connections. Note: All unused outputs are self-terminating and
do not require a termination plug.

5. Connect the round connector on the power supply to the POWER input jack (located on the back panel
of the distribution amp, immediately adjacent 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 on the computer, local monitor and remote data monitors.
Default Settings
Among the many features of the IN3264 and IN3268 Distribution Amplifiers is the ability to not only
have 1 x 4 or 1 x 8 configurations (respectively), but, by unterminating the input impedance, users can add
a loop-out to other DAs as well. This effectively converts the IN3264 into a 1 x 5 DA, and the IN3268 into
a 1 x 9.
The IN3264 is equipped with three sets of jumper pins per color (three for red, three for blue and three
for green) for a total of 9 individual jumpers (see Diagram 1-1). Each one has a specific purpose. The
factory default setup has all jumper pins closed except for J9, J11 and J13. These jumper pins are there to
be used in the event that another board is added, converting the DA into a 1 x 8, resulting in the IN3268.
These pins should remain open at all times.

Opening the J2, J3 and J4 pins will remove the 75 ohm termination for each color. This setting allows
users to connect a cable such as the IN9041 to the input and utilize a local monitor. Please note that if
there is no local monitor and the jumper pins are set to this position, there will be unnecessary “blooming”
or overdriving of the other four outputs.
The input jumper pins (J8, J10 and J12) must be closed at all times. If any of these jumpers are open
there will be no output because the pins are directly connected to the 15-pin input connectors (jumper pins
J8, J10 and J12 are used to interface the top and bottom boards of the IN3268 and should not be adjusted).
The factory default setting has them all closed. This allows the signal to be processed into the DA and
result in the proper 1 x 4 operation.
The IN3268 is very similar in operation and configuration to the IN3264. This unit has the same type of
board for the other four outputs, but the jumper pins on the top and the bottom boards of the IN3268 have
different configurations.
The bottom board should have all of the jumper pins closed except J2, J3 and J4, which remove the
termination and allow the top board to disengage the input. To place the proper 75 ohm termination to the
input, J2, J3 and J4 on the top board must be closed as well. The configuration of the top board is a little
different because there are only two sets of jumpers per color (see Diagram 2-1).

To allow a loop-output, the J2, J3 and J4 pins must be open on both the top and the bottom boards. Again,
the outputs will be overdriven if there is no local monitor connected to the input when the termination is
disabled. This may cause serious problems to the display device.
Warning: Jumpers should only be adjusted by qualified technicians! An
improper setting may lead to incorrect operation and could even result in
severe damage to the computer video port or the monitor.

Troubleshooting
The display device connected to the IN3264 / IN3268 output has a bad / scrambled image.
Solution 1: The display device connected to the output of the distribution amplifier may not be compatible
with the computer output. Many older LCD and Data Display units will not present signals
at resolutions higher than 640 x 480 or 800 x 600, or horizontal scan rates above 36 KHz or
48KHz. Make sure you know what resolution mode the computer video card is set to output.
While basic 640 x 480 VGA at 60 Hz refresh rate runs at 31.5 KHz, SVGA modes can be as
high as 48 - 58 KHz with the highest resolution settings such as 1600 x 1200 running at 80
KHz or higher depending on the refresh rate setting. Sun and SGI computers usually operate at
61KHz, 64KHz, or 71KHz at resolutions as high as 1280 x 1024.
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 cord 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.
The output image of the IN3264 / IN3268 is visible but has poor quality / low definition.
Solution: The output cables may be too long or of poor quality. INLINE offers several high-resolution
mini-coax cables for analog signals and a series of shielded twisted pair cables designed
specifically for digital video signal transmission. See page 7 for specific recommendations.
The unit doesn’t output any signal and the power light is not turning on.
Solution: The power adapter may have failed. It should feel warm to the touch after it has been plugged
in for a few minutes. If the adapter feels cool, replace it.
