PRODUCT OVERVIEW

DESCRIPTION

The IN1776QZX is a full-featured scan converter which transforms VGA or MAC type signals
into either standard NTSC or PAL video formats, which may then be displayed on a regular
video monitor or recorded to videotape. Whether you are making a sales presentation on the
road, holding a software training session, or demonstrating a new site on the Internet, you need
powerful tools to grab attention and keep your audience with you. Working in conjunction with
your computer, the IN1776QZX lets you transfer PC or MAC generated images to a wide variety
of conventional video equipment.

PRODUCT FEATURES

• Wide Input Signal Compatibility - The IN1776QZX accepts VGA and MAC type

computer video signals at resolutions from 512 x 384 up to 1024 x 768. The

IN1776QZX is compatible with scan rates from 24KHz – 66KHz and vertical refresh
rates from 50HZ – 100Hz, making it flexible enough to operate with a wide variety of
computer video signals.

• Infrared Remote Control - allows presenters to move freely around the room. The

remote control makes it easy to adjust picture height & width, position, underscan/
overscan, freeze, zoom, pan, flicker filter, brightness and all other controls up to 50' away
from the unit. The infrared control port also allows for complete system integration since
the IN1776QZX may be rack mounted and controlled by a third-party control system.

• Seven Position Flicker Filter - An advanced design lets users select one of seven

settings to produce the optimal combination of flicker reduction and image sharpness for
each type of display application.

• Zoom and Pan - By simply pressing a button, users may zoom-in to display an enlarged

view of detailed drawings or fine text (up to 2x magnification), press the pan controls to
browse smoothly around the picture, then press zoom again to see the entire screen.
Quadrant Zoom offers direct access to nine different positions on the screen.

• Local Monitor Output - provides a buffered signal for the local computer monitor. This

allows you to view the original high resolution signal on your computer monitor while
simultaneously viewing scan converted video on conventional video monitors or
projectors. No termination is required if the IN1776QZX is used without a local monitor.

• Flexible Output Formats - Featuring Composite Video, S-Video, and RGBS outputs, the

IN1776QZX Scan Converter connects easily to a wide variety of consumer, industrial,

and professional video equipment. All outputs are live at the same time, so, by connecting
to the Composite, S-Video and RGBS outputs, the unit may actually drive up to three
video displays simultaneously (in addition to the local computer monitor).

INPUT COMPATIBILITY

The IN1776QZX will work with video signals from PC compatible computers and the
Macintosh family of computers as follows:

VGA / SVGA / XGA

Resolutions: 640 x 480

800 x 600

1024 x 768

Vertical Refresh Rate: 50 to 100 Hz

MAC II / Quadra / Centris / Performa / Power Book / Power MAC

Resolutions: 512 x 384 (12” Color Monitor)

640 x 480 (13”/14” Color Monitor or Multiple Scan)

Vertical Refresh Rate: 50 to 100 Hz

Other Signals

The IN1776QZX automatically senses the characteristics of the input signal and adjusts itself
accordingly. This allows it to work with non-standard signals which fall within its operating
range. For instance, while standard VGA signals are 640 x 480 resolution / 60 Hz / 31.5 KHz in
the RGBHV format, the IN1776QZX will also accept a 640 x 480 / 60 Hz / 31.5 KHz signal in
the RGBS format. The main limiting factor for compatibility is not the vertical scan rates or

sync format, but the video resolution which must not exceed 1024 x 768 and the horizontal
scan rate which must not exceed 66 KHz.

3

Using an optional input adapter, the IN1776QZX may also accept signals other than the VGA
and MAC standards listed above as long as they fall within the following operating parameters:
Resolution: 512 x 384, 640 x 400, 640 x 480, 800 x 600, 823 x 624, 1024 x 768
Horizontal Scan Rate:

24 KHz - 66 KHz

Vertical Refresh Rate: Up to 100 Hz
RGB Video Signals: Analog Video, 0.7 Vp-p
Sync Signals: Composite Sync or Separate (H & V) Sync

OUTPUT COMPATIBILITY

The IN1776QZX output signal may be connected to many types of video equipment including
TV & presentation monitors, video projectors, VCRs and teleconferencing equipment. Video
output is offered in three formats:

Composite Video - Offers the widest compatibility with consumer video equipment such as TV
monitors, VCRs and other equipment with composite video input.

S-Video - Also known as Y/C, this output provides a clearer signal than the composite video
output and should be used whenever possible. S-Video may be connected to any video
equipment having an S-Video input such as video monitors, large screen monitors, video
projectors, and S-VHS and Hi-8 VCRs.

RGBS - This output provides the best clarity and color accuracy and should be used if your
display equipment has an RGBS input. This format is most frequently used with industrial and
professional grade video projectors, RGB monitors and retro-projectors.

INSTALLATION - PC COMPATIBLE COMPUTERS

Installation steps for PC computers are listed below and outlined in the diagram on the next page.
For Macintosh computer installations, see pages 6 & 7.

#1 Connect the computer’s VGA video port to the IN1776QZX Input.

- Disconnect the local computer monitor from the computer’s video port.

- Using the IN8006 cable supplied with the unit, connect the computer’s VGA video port to the
IN1776QZX
connector located on the rear of the computer. It looks like this:

#2 Connect the local computer monitor to the IN1776QZX.

Attach the VGA monitor cable to the

If you are using a laptop computer or do not wish to have a local monitor you may leave the

IN1776QZX LOCAL MONITOR OUTPUT port open - no termination plug is required.

#3 Connect the IN1776QZX VIDEO, S-VIDEO, or RGBS output to your display device or
VCR.

Composite Video - Select either the RCA connector or the BNC connector on the IN1776QZX.

You may not connect displays to both the RCA and BNC connector simultaneously.

VGA / MAC INPUT port. The computer’s VGA port is a 15-pin HD female

LOCAL MONITOR OUTPUT port on the IN1776QZX.

RCA Connector - connect the IN1776QZX VIDEO output to the Video input on the
video monitor or VCR using the IN9095 RCA to RCA 6’ video cable (provided).

BNC Connector - connect the IN1776QZX

VIDEO output to the Video input on the

video monitor or VCR using a BNC male to BNC male 75 ohm coaxial cable. The
IN7200-1 Series cables, available in a variety of lengths, are well suited for this purpose.

S-Video - Connect the IN1776QZX

S-VIDEO output to the S-Video input on the video monitor

or VCR using the IN9096 S-Video 6’ cable (provided).

RGBS - Connect the IN1776QZX

RGBS output to the RGBS input on the RGB monitor or

video projector using a 4-BNC coaxial cable with male connectors at each end. The IN7000-4,
IN7100-4 and IN7200-4 cables, available in a variety of lengths, are well suited for this purpose.

#4 Check the power selector switch and connect the A/C power source.

- Check to see that the 110 / 220 switch on the back of the unit matches the local A/C line level.
This switch can be changed if necessary by using a small straight slot screw driver.

- Connect the IN1776QZX power entry module to an A/C power source with the power cord
provided (US versions only). For countries with A/C wall plugs other than Edison-style, use a
standard computer-type power cord with a female IEC connector on one end and the appropriate
male A/C power connector on the other end.

#5 Load batteries into the Infrared Remote control.

The IR remote control requires (4) AAA batteries (included with the unit). Place these in the
battery holder in the back of the remote control as indicated on the drawing inside the unit.
