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.
