Introduction
About this Manual
This manual contains installation, configuration, and operating information for the
Extron IN1404XT video scaler and switcher (referred to in this manual as the
“scaler”).
• Chapter 1 identifies the scaler’s features.
• Chapter 2 details how to install the scaler.
• Chapter 3 describes how to operate the scaler and use all of its features.
• Chapter 4 provides information about programming and operating the scaler
under RS-232 control, such as from a PC or host controller.
• Appendix A lists the scaler’s specifications and pertinent part numbers.
About the Scaler
The Extron IN1404XT is a video scaler that incorporates a four-input video and
stereo audio switcher (figure 1-1). The scaler accepts NTSC/PAL/SECAM/NTSC
4.43 S-video (Y/C) and composite video inputs and stereo audio inputs on all four
inputs and high resolution RGB video and interlaced or progressive component
(YUV) video on inputs 3 and 4. The IN1404XT scales the inputs to standard VGA
and HDTV resolutions and refresh rates and outputs RGBHV, RGBS, or RGsB
video and stereo audio. Input 4 can also be set to a passive mode that provides no
decoding, scaling or change of refresh rate and can be set as a timing reference for
seamless switching. The scaler can seamlessly switch to and from passive input 4
to bring professionalism and style to boardrooms or other system integration
environments. Seamless switching allows switching between sources without a
loss of sync. The scalers’ scaling capabilities permit differing video formats on each
input to be displayed by a common projector.
Each video input is individually configurable to allow for different video formats.
The scaler allows analog RGBHV, RGBS, and RGsB video, component video,
S-video, and composite video signals to be displayed on a device with a fixed
resolution and aspect ratio, such as an liquid crystal display (LCD) projector, digital
light processor (DLP) projector, or plasma display.
The scaler inputs high-resolution RGBHV/RGBS/RGsB video, and component
video on two sets of five BNC connectors. The scaler inputs S-video on 4-pin mini
DIN connectors (inputs 1 and 2) and on two sets of two BNC connectors (inputs 3
and 4). The scaler inputs four composite video inputs on BNC connectors. The
scaler inputs audio on RCA connectors.
The IN1404XT scales the input up to any of 48 output resolutions and rates and
outputs the scaled video, as two identical RGBHV, RGBS, or RGsB video outputs,
on five BNCs and a 15HD connector. Additionally, the scaler acts as a twisted pair
(TP) transmitter, outputting the identical video signal on an RJ-45 connector for
connection to an optional Extron VTR001CM TP receiver. (See TP transmission, in
this chapter, for more information about the RJ-45 output.) With all three video
outputs active at all times, the IN1404XT can drive three video displays
simultaneously, with no need for a distribution amplifier.
There is one stereo audio output, on left and right RCA connectors.
For upscaling, the IN1404XT converts the horizontal and vertical sync timing and
the number of lines of the lower-resolution video input to match the native
resolution of the display. This produces an undistorted, brighter picture.
The scaler is housed in a rack-mountable, 1U high, 17.5” wide metal enclosure.
With the included mounting ears, the scaler is rack-mountable. The scaler has an
internal 100VAC to 240VAC, 50/60 Hz, 25 watts auto-switchable power supply that
provides worldwide power compatibility.

TP transmission
The TP output on the RJ-45 connector and an optional Extron VTR001CM receiver
provide a system for long-distance distribution of computer (RGBHV or RGBS)
video over Extron’s skew-free A/V UTP cable or over CAT 5 unshielded twisted
pair (UTP), shielded twisted pair (STP), or foil shielded twisted pair (FTP) cable.
TP cable advantages
Extron’s skew-free cable or CAT 5 cable is a fraction of the size of coaxial cable, as
well as being much lighter, more flexible, and far less expensive. These TP
products make cable runs simpler and less cumbersome. Termination of the cable
with RJ-45 connectors is simple, quick, and economical.
Video Camera
VCR/DVD
The VTR001CM can receive RGsB signals from the scaler. However, the red,
green, and blue video signals’ black levels are not clamped to a 0V reference, as
for RGBHV or RGBS. For most displays, this is not a problem. On some
displays (such as some LCD displays) however, the black levels of the red,
green, and blue signals may change as the average picture level changes,
resulting in an unacceptable image.
1-3IN1404XT Video Scaler and Switcher • Introduction
Introduction, cont’d
Features
Inputs —
Video inputs — The scaler switches among two fully-configurable RGB, HDTV
component video, interlaced component video, progressive scan video,
S-video, or composite video inputs on 5 BNC connectors (inputs 3 and 4); two
S-video inputs on 4-pin mini-DIN connectors (S-video inputs 1 and 2 only);
or composite video inputs on single BNC connectors (composite video inputs
1 and 2).
Audio inputs — The scaler switches among four unbalanced stereo audio inputs
on RCA connectors. Inputs can come from sources such as a VCR, DVD
player, computer audio card, or other audio device that outputs a stereo linelevel signal.
Outputs —
Standard video outputs — The IN1404XT outputs scaled video signals as
progressive RGBHV, RGBS, or RGsB, from 640 x 480 up to 1365 x 1024, to
match the optimum or native resolution of virtually any display device, on
five BNC connectors and a 15-pin HD connector.
The output refresh rate is selectable as desired. When used with LCD or DLA
displays, Extron recommends the 60 Hz setting. Higher output refresh rates
can be used with CRT displays to reduce flicker.
TP video output — The scaler outputs a third video signal encoded into a set of
proprietary analog signals on an RJ-45 connector. The scaler transmits this
output in the same format as Extron’s VTT001CM TP transmitter. An
optional Extron VTR001CM receiver can receive this set of signals and
convert them to a high resolution RGBHV, RGBS, or RGsB output (identical
to the 5-BNC and 15-pin HD output).
Audio outputs — The scaler provides an unbalanced line level signal that is
identical to the input signal. This output can drive any line level compatible
audio unit, or a local device such as powered speakers.
Video output resolutions —
The IN1404XT outputs an image scaled up to the following output resolutions:
• 640 x 480 (VGA) at 60 Hz, 72 Hz, 75 Hz, 85Hz, 96 Hz, 100Hz, and 120 Hz
•
800 x 600 (SVGA) at 60 Hz, 72 Hz, 75 Hz, 85Hz, 96 Hz, 100Hz, and 120 Hz
• 852 x 480 at 60 Hz, 72 Hz, 75 Hz, 85Hz, 96 Hz, 100Hz, and 120 Hz
• 1152 x 864 at 60 Hz, 72 Hz, 75 Hz, and 85Hz
• 1024 x 768 (XGA) at 60 Hz, 72 Hz, 75 Hz, and 85Hz
• 1280 x 720 (HDTV - 720p) at 60 Hz, 72 Hz, 75 Hz, 85Hz, 96 Hz, and 100 Hz
• 1280 x 768 at 56 Hz, 60 Hz, and 65 Hz
• 1280 x 1024 (SXGA) at 60 Hz, 72 Hz, and 75 Hz
• 1365x 768 (wide XGA) at 60 Hz, 72 Hz, 75 Hz, and 85 Hz
• 1365 x 1024 (plasma) at 60 Hz
Advanced motion compensation — Extron’s video processing techniques,
advanced motion prediction and compensation methods treat motion content
Either S-video or composite video, but not both, can be connected to input 1
and to input 2. The two inputs can each be a different video format, but only
one format can be connected to an input.
IN1404XT Video Scaler and Switcher • Introduction1-4
and still content with different algorithms to yield high fidelity images that are
free of visible scan lines.
Inverse 3:2 pulldown detection for NTSC for film-originated video material —
This advanced film mode processing feature helps maximize image detail
and sharpness for video sources that originated from film. When film is
converted to NTSC video, the film frame rate has to be matched to the video
frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts
can result if conventional deinterlacing techniques are used on film-source
video. The IN1404XT’s advanced film mode processing recognizes signals
that originated from film. The scaler then applies video processing
algorithms that optimize the conversion of video that was made with the 3:2
pulldown process. This results in richly detailed images with sharply
defined lines.
Quad-standard decoding — The IN1404XT’s video decoder provides accurate
video decoding of composite video and S-video in the NTSC, PAL, SECAM,
and NTSC 4.43 standards. The advanced 3-line adaptive comb filter that
decodes composite video reduces cross-color interference and hanging dots
while maintaining maximum image bandwidth and detail.
Seamless Switching - Input 4, when configured as a passive (unscaled) input,
serves as a time reference for seamless switching. The IN1404XT provides a
seamless transition between scaled inputs on 1, 2, or 3 (RGB, component,
S-video, or composite video) and the passive RGB video on input 4.
Picture controls — A wide variety of picture controls are available for fine picture
adjustments:
• Position
• Size
• Aspect ratio
• Hue
• Saturation
• Brightness and contrast
• Gamma
• Horizontal tracking
• Sharpness
Once these adjustments are made, the settings are stored in non-volatile
memory and automatically recalled when the same input source is selected
again.
Advanced image adjustment controls — A wide variety of picture controls are
available to optimize the image when the scaler is used with proprietary and
non-standard input signals.
Once these adjustments are made, the settings are stored in non-volatile
memory and automatically recalled when the same input source is selected
again.
Blue screen mode — The scaler can be set to output a blue video field, to help
installers calibrate the monitor or projector. Blue screen is always available,
whether or not an input is present or properly adjusted.
On screen menus - The scaler puts its menu displays on the output video stream,
for display by the output monitors or projectors. The menu system provides
easy control of video adjustments including hue, color, contrast, brightness,
1-5IN1404XT Video Scaler and Switcher • Introduction

gamma, sharpness, image size, image position, and edge blanking.
Individual image settings can be optimized and stored for each input. Each
time an input is selected, all image settings stored for that input are
automatically recalled. The on-screen menus also make it easy to verify and
adjust advanced settings such as output signal resolution, refresh rate, sync
format; the RS-232 control options; and the reset to factory defaults function.
A handy System Info menu option uses the on-screen display to show
comprehensive information about the input and output signals and scaler
settings.
Audio follow and breakaway — Audio switching can follow its corresponding
video input signal or, under RS-232 control, audio can be broken away from
the video input.
Except as noted in Video breakaway, below, when a new input channel is
selected, the audio automatically switches to the newly selected input
channel.
Video breakaway — Under RS-232 control, video can be switched without
disturbing the audio switch.
Operational flexibility — Operations such as input and scaling selection, picture
controls, and saving and recalling of presets can be performed on the front
panel or over the RS-232 link. The RS-232 links allow remote control via a PC
or control system.
• Front panel control — The scaler’s front panel controller and on-screen
menus support individual input selection, resolution selection, volume
control, and complete configuration of the scaler.
• ASCII character command set — The remote control protocol uses Extron’s
ASCII character command set for easy programming and operation.
Freeze mode — Provides a high quality still image for applications that require
close examination of a specific video frame. Freeze mode operates for video
and RGB signals that are processed by the scaling circuitry. Passive
(unscaled) video on input 4 cannot be frozen.
Blank mode — Suppresses the output video image. Blank silences the R, G, and B
video outputs but the scaler still outputs sync. This ensures that the output
device does not lose sync lock. Blank mode operates for video and RGB
signals that are processed by the scaling circuitry. Passive (unscaled) video
on input 4 cannot be blanked.
User memories — The IN1404XT provides 128 user memories that store all video,
audio, and input parameters. User memories allow the unit to be optimized
for a large number of sources and gives the capability to recall those settings
quickly. The memories make it easier to add to the number of inputs to the

Installation Overview
To install and set up an IN1404XT video scaler and switcher for operation, perform
the following steps:
Disconnect power from all of the equipment, including the video and audio
1
source(s), and the devices that will receive the output video and audio signals.
Ensure the power switch on the scaler is off.
Rack mount the scaler if desired. See Mounting the Scaler in this chapter.
2
Connect the video and audio input cables. See Input connections in this
3
chapter.
Connect the standard video and audio output cables. See Standard output
4
connections in this chapter.
If desired, connect the TP cable between the scaler and an optional VTR001CM
5
TP receiver and connect the output cables from the TP receiver to the display.
See TP output connection in this chapter and refer to the VTT001CM and
VTR001CM - Twisted Pair Transmitter and Receiver manual, part # 68-760-01.
If desired, connect the RS-232 cable. See RS-232 connection in this chapter.
6
Connect the AC power cable. See Power connection in this chapter. Turn on
7
the sources, video and audio destinations, and the scaler.
Configure the scaler’s inputs and configure the output for the optimum
6
image. See chapter 3, Operation and chapter 4, Programmer’s Guide.
Mounting the Scaler
The scaler includes four installed rubber feet. If you are going to rack mount the
scaler, mount it before cabling it (see Rack mounting, below). The IN1404XT is
exactly 1U high without the rubber feet; if you plan to rack mount the scaler with
other equipment directly underneath it, the feet must be removed.
Rack mounting
Rack mount the scaler as follows:
1. Remove the three enclosure screws on one side of the scaler (figure 2-1).

2. Attach one rack mount bracket to that side of the scaler with three screws
removed in step 1.
3. Repeat steps 1 and 2 on the other side of the scaler.
4. Insert the scaler into the rack, align the holes in the mounting bracket
with those of the rack.
5. Secure the scaler to the rack with machine screws.

RJ-45 female connector. Connect the other end of the TP cable to an optional
Extron VTR001CM or other compatible Extron TP receiver. See Optional
Accessories, in Appendix A, Reference Information, for compatible TP receivers.
The VTR001CM can receive RGBHV and RGSB signals from the scaler with
no loss of image quality. The VTR001 CM can also receive RGsB signals from
the scaler. However, the red, green, and blue video signals’ black levels are not
clamped to a 0V reference, as for RGBHV or RGBS. For most displays, this is
not a problem. On some displays (such as some LCD displays) however, the
black levels of the red, green, and blue signals may change as the average
picture level changes, resulting in an unacceptable image.
Termination of TP cable
Figure 2-5 details the recommended termination of TP cables in accordance with
the TIA/EIA T 568A and TIA/EIA T 568 B wiring standards. You can use either
standard, but ensure you use the same standard on both ends of the cable.

Cable testing
To ensure proper cable termination, each transmission cable system that uses CAT 5
cable should be tested (Extron’s skew-free UTP cable does not need to be tested).
Testing the cable from the RJ-45 connections at the transmitter and receiver gives
the most accurate indications of cable problems.
There are two varieties of cable runs: simple runs, in which a single cable is
terminated only at the transmitter and receiver, and complex runs, which can
include patch bays and multiple terminations and lengths of cable. In either case,
the entire cabling system should be tested.
A complete test measures cable length and tests the wire map, attenuation, NEXT,
PSNEXT, ELFEXT, PSELFEXT, return loss, ACR and PSACR. All of these tests are
critical for digital data transfer, but not for analog video. While all of these tests are
important indicators of the quality of the cable termination, the most critical testing
parameters for video transfer are wire map (T-568-A or B termination) and pair
length measurements. The largest concern is equalization of skew between cable
pairs. Cable systems of 300 feet or less should exhibit no transmission problems if
they pass at least CAT 5 channel certification testing.
2-5IN1404XT Video Scaler and Switcher • Installation
Installation, cont’d
The Microtest OMNI SCANNER 2 performs comprehensive certification testing to
the proposed CAT 6 standards. Other manufacturers also make testing equipment.
The tests include advanced diagnostics for troubleshooting the cause and location
of many cable and termination problems. For simple installation testing, the
Microtest MICRO SCANNER PRO tests wire map and cable length, including
individual cable pair length.
Equalizing pair skew
The manufacturing process for network (CAT 5) UTP cable leads to a condition
called pair skew. For best results, pair skew needs to be equalized when using the
CAT 5 cable in A/V applications. The design of Extron’s skew-free A/V UTP cable
minimizes pair skew to the point that equalization is not required.
Skew exists between pairs when the physical length of one wire pair is different
from another. As the transmission cable length increases, the amount of skew
increases. Skew affects the displayed image when the differential length between
wire pairs exceeds 2 feet, causing the timing of the red, green, and blue video
signals to appear out of alignment (horizontal registration errors). A white vertical
line on a black field can appear as individual red, green, and blue lines that are
close together; the signal transmitted on the shortest wire pair leads the other colors
and appears to the left on the display.
UTP cable test equipment measures and reports wire pair length. The report on the
various pair lengths can be used in equalizing pair skew. The nominal velocity of
propagation (NVP — the speed at which the signal travels on the transmission line,
measured as a percentage of the speed of light) of TP cable is very close to that of
conventional coaxial cable. The similarity in NVP means that:
• by using an Extron IN9045-L6 15HD male-to-5 BNC male, 6’ cable, to adapt
the output on a 15HD connector to BNC connectors,
• and then adding an additional length of coax equal to the length of pair skew,
placed on the receiver’s output,
you can equalize the effects of pair skew (figure 2-6).
If UTP cable test measurement cannot be done, pair skew can still be equalized by
viewing a test pattern with a critical eye. Examine the test pattern for loss of
horizontal registration and, through a process of trial and error, equalize any pair
skew with coax extensions on the red, green, and/or blue outputs.
Extron skew compensation coax cables are available in lengths of 2 through 20 feet,
see Appendix A, Reference Information, for part numbers.

To enable seamless switching, input 4 must be configured as RGB passive
(unscaled) on the Signal Format screen. However, once it is configured as
passive and if input 4 is selected, on-screen menus are not displayed.
No video adjustments are available for the input 4 video signal when it is
configured as passive (unscaled) but audio and other input variables are still
adjustable. Because on-screen displays will be blanked for input 4 once it is
configured as passive, it will be helpful to configure all of the input 4 options
before you configure the input as passive. If, later, you need to change any of
the input 4 settings, the easiest way is to temporarily set input 4 to one of the
scaled output settings. See Signal Format screen in this chapter.
Alternatively, you can make the adjustments under RS-232 control.
