About This Guide

This manual contains installation, configuration, and operating information for the Extron ISM482 Integration Scaling Matrix Switcher.

In this manual, the terms “switcher” and “ISM” are used interchangeably to refer to the ISM482.

About the Switcher

The ISM 482 is an eight-input, two-independently-scaled-output, video and stereo or mono audio matrix switcher. Figure 1 on the next page shows a typical ISM 482 application. The switchers accept high resolution RGB video, YUV (component) video, S-video (Y/C), and composite video inputs; scale the inputs; and output RGBHV or RGBS video and stereo audio. Triple-Action Switching™ (RGB delay) blanks the screen during the switch to prevent distracting video glitches. The switcher’s two independent scalers permit differing video formats on each input to be displayed in different resolutions on different projectors.

Each video input is individually configurable to allow for different video formats. The ISM allows analog RGBHV, RGBS, RGsB, and RGBcvS video, component video, S-video, and composite video signals to be displayed on a device with a fixed resolution and aspect ratio, such as a liquid crystal display (LCD) projector, digital light processor (DLP) projector, or plasma display.

The ISM provides two separate outputs. The selected input can be switched to either or both outputs. With an optional DVI output card, the ISM converts the scaled image to DVI as an additional set of output 1 signals.

The switcher inputs all valid video signal formats on eight sets of five BNC connectors. The ISM 482 scales the input up or down to a wide variety of output resolutions and rates. The switcher outputs the scaled video, as RGBHV or RGBS, on two sets of output connectors, consisting of five BNCs and a 15-pin HD connector. These connectors share identical outputs.

Several of the output resolutions and rates include the Extron Accu-RATE Frame Lock™ (AFL™), a proprietary technology that locks the output frame rate to the refresh rate of input 1, solving the image tearing problem that can result from different input and output rates. The switcher features HDTV 576p, 720p, 1080p, and 1080i outputs.

Figure 1. Typical ISM 482 Integration Scaling Matrix Switcher Application

The ISM receives and outputs the stereo audio on 5-pole captive screw connectors.

For upscaling, the ISM 482 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 than an unscaled input would.

For downscaling, the ISM 482 accepts any computer resolution, up to 1600 x 1200, with horizontal scan rates up to 100 kHz and vertical scan rates up to 120 Hz, and converts the input to match the native resolution of the display.

The switcher is ideal for displaying images on projectors with limited display resolutions, such as LCD projectors, DLP projectors, and plasma projectors.

The switcher features built-in test patterns to aid in monitor or projector set-up and evaluation.

The switcher is housed in a rack-mountable, 3U high, 17.5 inch wide, metal enclosure. The ISM has an internal 100VAC to 240VAC, 50/60 Hz, 30 watts power supply that provides worldwide power compatibility.

ISM 482 Integrated Scaling Matrix Switcher • Introduction 2

Features

• Inputs

• Video inputs — The ISM switches among eight fully-configurable RGB, HDTV

component video, component video, S-video, and composite video inputs on five BNC connectors per input.

• Audio inputs — The ISM switches among eight balanced or unbalanced stereo or

mono audio inputs on 5-pole captive screw connectors.

• Outputs

• Standard video outputs — The ISM outputs individually scaled video signals as

RGBHV or RGBS. Two sets of BNC connectors and two 15-pin HD connectors are provided. One set of BNC connectors and one 15-pin HD connector display the output 1 image, and the other set of BNC connectors and 15-pin HD connector display the output 2 image.

• Optional DVI video output — If you install the optional DVI output card, a single

buffered DVI-D signal can be output as an additional output 1 image.

NOTE: For output resolutions with less than 1024 pixels horizontally, the

optional DVI output’s true horizontal resolution is limited to 1024 pixels. For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI output’s true horizontal resolution is limited to 1280 pixels. The DVI card outputs all other selected resolutions normally (see the table on page 20).

• Audio outputs — The ISM outputs the selected unamplified, line level, balanced or

unbalanced stereo or mono audio on 5-pole captive screw connectors.

• Accu-RATE Frame Lock™ (AFL™) — A patented technology exclusive to Extron that

solves frame rate conversion issues experienced by video scalers. When video input and output refresh rates differ, occasionally the two rates cross over each other. The result is a glitch or image freeze on the display. AFL solves this problem by locking the output frame rate to the frame rate of input 1.

• Dynamic Motion Interpolation™ (DMI™) — This video processing technique is an

advanced motion prediction and compensation method that treats motion content and still content with different algorithms to yield high fidelity images.

• 3:2 pulldown detection for NTSC video sources and 2:2 film detection for PAL

— These advanced, patent pending, film mode processing features help 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 ISM’s advanced film mode processing recognizes signals that originated from film. The ISM 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.

A similar process, 2:2 film detection, is used for PAL film-source video.

• Audio follow and breakaway — Audio switching can follow its corresponding video

input signal or it can be broken away from the video input. Audio breakaway switching can be done via front panel control or under RS-232 or Ethernet remote control.

• Audio gain/attenuation — Users can set the input level of audio gain or attenuation

(-24 dB to +9 dB) via the RS-232 port, Ethernet link, or from the front panel. Individual input audio levels can be adjusted so there is no noticeable volume difference between sources.

ISM 482 Integrated Scaling Matrix Switcher • Introduction 3

• Ethernet port — Supports connection to an Ethernet LAN so that the switcher can be

accessed and operated from anywhere in the world with a computer using a standard Internet browser.

• Quad-standard video decoder — The switcher uses a digital, four-line adaptive comb

filter that can decode NTSC 3.58, NTSC 4.43, PAL, and SECAM.

• Test patterns — The switcher features built-in test patterns to aid in monitor or

projector setup and evaluation.

• Blue mode — The switcher can be set to output the blue video signal and sync

signal(s) only, to help installers calibrate the monitor or projector.

• Triple-Action Switching™ (RGB delay) — RGB delay mutes the R, G, and B video

planes to blank the screen while the scaler locks to the new sync, so that a noise-filled scramble is not shown on the monitor during the transition. The time delay between the RGB and sync signals is user adjustable up to five seconds under front panel, Simple Instruction Set (SIS™), and Windows program control.

• Auto memories — The eight inputs support 16 auto-recall memories each, based on

the incoming frequency. Information on sizing, centering, detail, contrast, and brightness is saved.

• Auto Image™ — The auto imaging feature automatically sizes and centers the selected

input to fill the screen. Auto imaging can be manually initiated on the current input, or can be enabled to globally size and center each new input signal automatically.

• Memory presets — The ISM 482 has memory for up to 128 presets that allow the

user to use RS-232 commands to save and recall color, tint, contrast, brightness, centering, sizing, and filtering information.

• Aspect ratio memories — Three memories for each input save different color, tint,

contrast, brightness, detail, size, and centering settings.

• Freeze mode (under SIS and Windows program control only) — Locks the output

display to the selected image. Once frozen, an input can be removed without losing the output image. This feature lets the ISM store a still image.

• Rack mounting — The 3U high switcher can be mounted in any conventional 19 inch

wide rack.

DVI output’s true horizontal resolution is limited to 1024 pixels. For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI output’s true horizontal resolution is limited to 1280 pixels. The DVI card outputs all other selected resolutions normally (see the table on page 20).

Ethernet Connection

g Ethernet port — If desired, connect the switcher to an Ethernet LAN or WAN via this

RJ-45 connector. Ethernet control allows the operator to control the switcher from a remote location. When connected to an Ethernet LAN or WAN, the switcher can be accessed and operated from a computer running a standard Internet browser.

Ethernet connection indicators — The Link and Act LEDs indicate the status of the

Ethernet connection.

The Link LED indicates that the switcher is properly connected to an Ethernet LAN. This LED should light steadily.

The Act LED indicates transmission of data packets on the RJ-45 connector. This LED should flicker as the switcher communicates.

Cabling and RJ-45 connector wiring

It is vital that your Ethernet cables be the correct cables, and that they be properly terminated with the correct pinout.

Choosing a network cable

Ethernet links use Category (CAT) 3, 4, 5, 5e, or 6, unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to 328 feet (100 m).

NOTES:

• Do not use standard telephone cables. Telephone cables will not support Ethernet

or Fast Ethernet.

• Do not stretch or bend cables. Transmission errors can occur.

The cable used depends on your network speed. The ISM supports both 10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet), half-duplex and fullduplex, Ethernet connections.

• 10Base-T Ethernet requires, at a minimum, CAT 3 UTP or STP cable.

• 100Base-T Fast Ethernet requires, at a minimum, CAT 5 UTP or STP cable.

ISM 482 Integrated Scaling Matrix Switcher • Installation 9

Wiring the network cable

The cable can be terminated as either a patch cable or a crossover cable (see figure 9) and must be properly terminated for your application:

• Patch (straight) cable — Connection of the ISM to an Ethernet hub, router, or

switcher that also hosts a controlling computer

• Crossover cable — Direct connection between the ISM and a controlling computer

g Status display — The 20-column by 4-line LCD displays configuration menus and

status information (see “Front Panel Operations,” below, for details).

Menu Control Buttons

h Menu button — The Menu button enters and moves through the main menu system in

the ISM (see “Front Panel Operations,” below, for details).

Next button — The Next button steps through the submenus in the ISM menu system

(see “Front Panel Operations,” below, for details).

Adjustment Knobs

i Adjust (horizontal) and Adjust (vertical) knobs — The Adjust and Adjust

knobs change settings when used in conjunction with the picture adjustment buttons or the menu system. Rotate these knobs to change picture settings when one of the picture adjustment buttons is selected. In the menu system, rotate these knobs to scroll through the selection options and make adjustments.

Front Panel Operations

The following paragraphs detail the power-up process and then describe the menu system, the picture adjustments, and selection of executive mode.

Power

Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks all of the front panel LEDs and then lights only the LEDs for the previously selected output and the tied input. The self-test also displays the model name, part number, and the firmware version in the

Power

LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle, alternating between two displays: one showing the inputs selected for outputs 1 and output 2, and the other showing the selected output rates (see figure 16). An error-free power up self-test sequence leaves all of the LEDs off, with the exception of the selected output’s and input’s LEDs, off and the LCD cycling through the default displays.
