Integration Scaling
Multiswitcher

The multiswitcher accepts up to eight video inputs of various resolutions on five

female BNC connectors per input. Depending on the output board congurations,

the multiswitcher scales, down-converts, or simply passes the video inputs to

output RGB or YUV video. The outputs are made on ve female BNC connectors,
or two 15-pin HD connectors (dual wideband board only), DVI-D connectors, and
HD-SDI connectors (supports SMPTE 292M standard). Inputs and outputs are

made in the following signal formats:

• RGB (RGBHV, RGBS) video

• YUV-HD (HDTV) video

• Progressive YUV component video

• Interlaced YUV component video

• S-video (Y/C)

• Composite (NTSC, PAL, SECAM) video
Each video input is individually congurable for color, tint, brightness, contrast,

detail, position, size, and zoom via the front panel, RS-232/RS-422, or Ethernet

control. The ISM also allows the various high-resolution and low resolution video
formats to be displayed on a device with a fixed resolution and aspect ratio, such as
a liquid crystal display (LCD) projector, a digital light processor (DLP) projector, a

plasma display, or, optionally, a DVI or HD-SDI device.

Figure 1-1 shows an example of an ISM 824 application.

Figure 1-1 — Typical ISM 824 application

Balanced or unbalanced stereo or mono audio inputs are made on eight 5-pole
captive screw connectors, numbered 1 through 8.

Introduction, cont’d

Individual audio input gain and attenuation can be displayed and adjusted from

-18 dB to +24 dB via the front panel, Ethernet, or RS-232/RS-422 control.

Output volume can be displayed and adjusted as desired through a range of

0 to 64 dB, in 1 dB steps via the front panel, Ethernet or RS-232/RS-422 control.

In addition, all audio settings can be set to the same desired input and output

setting via the Windows Control Program. Both input gain and output volume
adjustments are available at the front panel, by RS-232/RS-422 control, or Ethernet

connection.

Serial control of the switcher by RS-232/RS-422 is achieved by connecting a host
device such as a PC or control system to the rear panel 9-pin D connector, or the 2.5
mm mini stereo jack on the front panel (only RS-232 control). This allows the user

to control and congure the multiswitcher using Extron SIS
ISM 824 Windows Control Program. See chapter 4, “SIS

Control”, and chapter 5, “ISM 824 Software”, for details.

An Ethernet connection is made using the RJ-45 connector on the rear panel.

The ISM 824 features HDTV 480p, 576p, 720p, 1080i, and 1080p outputs.

The switcher has 16 user defined presets, allowing the user to save the current
video and audio tie (input x to output x) as an I/O preset to any one of 16 preset
memory addresses via the front panel. Presets 1 through 8 are assigned to the
input buttons, and 9 through 16 are assigned to the output buttons. See chapter 3,

“Operation and Setup”, for details.

The switcher is housed in a rack-mountable, 3U high, 17.5" wide, metal enclosure
and uses an external 100 VAC to 240 VAC, 50/60 Hz, 65 watt power supply.

ISM 824 Integration Scaling Multiswitcher • Introduction

Features

Inputs —

Video inputs — The ISM switches among eight congurable RGB, HDTV

component video, component video, S-video, and composite video inputs.

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

mono audio inputs on 5-pole captive screw connectors.

Outputs —

Standard pass-through video outputs — The ISM 824 outputs any video signals,

unprocessed, on outputs 1 and 2.

Optional output boards — With optional scaler, scan converter, dual or single

wideband output boards installed in the expansion slots, up to six additional
program video outputs are available. The output signals are scaled,
converted or passed through, based on the board type installed:

• ISM RGB, ISM DVI, or ISM HDSDI (Universal Video and RGB Scalers
with BNC, DVI, or HDSDI output connectors) — Scales any low or high

resolution input signal to a high resolution signal up to 1920 x 1200, 720p,
1080i, or 1080p.

• ISM VS (Video Scaler) — Scales any low resolution input up to
1400 x 1050 or HDTV 1080p. High resolution inputs pass-through

unchanged.

• ISM SC Scan Converter — Converts any high resolution input signal to a
low resolution signal. Genlocking of any converted signal to an external

sync source is available with this output board.

• ISM 2WB Dual output wideband — This optional board takes any two
input signals and passes them through unprocessed on two 15-pin HD

connectors.

• ISM 1WB Single output wideband — This optional board takes any
input signal type and passes it through unprocessed on BNC connectors.

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

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

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

These advanced film mode processing features help maximize image detail

and sharpness for video sources that originated from lm. When lm 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 de-interlacing 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 2:2 pulldown process is used for PAL film-source video.
Switching flexibility — Provides individually buffered, independent matrix

switched outputs with audio follow and audio breakaway for audio models.

• Tie any input to any or all outputs

• Quick multiple tie — Multiple inputs can be switched to multiple outputs

simultaneously. This allows all displays (outputs) to change from source to
source at the same time.

• Audio follow — Audio can be switched with its corresponding video input

via front panel control or under Ethernet or RS-232/RS-422 remote control.

ISM 824 Integration Scaling Multiswitcher • Introduction

Introduction, cont’d

• Audio breakaway — Audio can be broken away from its corresponding

video signal. This feature allows any audio signal to be selected with any
video signal simultaneously to one or all outputs in any combination. Audio

breakaway switching can be done via front panel control or under Ethernet or

RS-232/RS-422 remote control.

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

(-18 dB to +24 dB) via the RS-232/RS-422 or Ethernet link, or from the front

panel. Individual input audio levels can be adjusted so there are no noticeable
volume differences between sources.

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

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

Quad-standard video decoder — The switcher uses a digital comb filter that can

decode NTSC 3.58, NTSC 4.43, PAL, and SECAM signals.

Triple-Action Switching

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

5 seconds under front panel, SIS, and program control.

Rack mountable — The 3U high switcher can be mounted in any 19" wide rack.

™

(RGB delay) — RGB delay mutes the R, G, and B video

Optional output board features

The series of optional output boards have the following features available.

ISM RGB, ISM DVI, and ISM HDSDI boards

Auto Image™ — Only for scaled outputs. The auto imaging feature automatically

sizes and centers the selected input to fill the screen. Auto imaging can be
selected for individual outputs as desired.

Test patterns — This board features built-in test patterns to aid monitor or projector

setup and evaluation. Some of the test patterns vary based on the output rate
selected. The test patterns available are:

• 8 color split • 4:3/16:9 hatch • 4x4 crosshatch

• gray scale • ramp • alternating pixels

• crop • aspect ratios; 1.33, 1.78, 1.85, and 2.35

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

to help installers calibrate the monitor or projector.

Film mode — Advanced film mode processing techniques maximize image detail

and sharpness for NTSC and PAL sources that originated from film.

Auto memories — Only for scaled outputs. The inputs support 16 auto-recall

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

Aspect ratios conversion — Any input can be adjusted horizontally and vertically

to meet a specific aspect ratio requirement.

Input presets — Only for scaled outputs. The ISM 824 has memory for up to 128

presets, allowing the use of SIS commands to save and recall input type,
sampling, color, tint, contrast, brightness, centering, sizing, and filtering
information.

User presets — Only for scaled outputs. Three presets for each input save different

settings for color, tint, contrast, brightness, detail, size, centering, and input
configurations.

ISM 824 Integration Scaling Multiswitcher • Installation

Mounting the Switcher

If the ISM 824 is to be rack mounted, it is important to mount it before cabling it.
Four uninstalled rubber feet are included with the ISM 824. Install the feet only if
the unit is to be mounted on top of a table (see “Tabletop placement” below).

Tabletop placement

For tabletop placement, install the self-adhesive rubber feet/pads (provided) onto
the four corners of the bottom of the device.

UL guidelines for rack mounted devices

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the ISM

824 in a rack.

1. Elevated operating ambient temperature — If installed in a closed or multi-unit

rack assembly, the operating ambient temperature of the rack environment may
be greater than room ambient temperature. Therefore, install the ISM 824 in an
environment compatible with the maximum ambient temperature

(Tma = +122 °F, +50 °C) specied by Extron.

2. Reduced air flow — Install the equipment in a rack so that the amount of air flow

required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack so that a hazardous

condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Connect the equipment to the supply circuit and consider

the effect that circuit overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should
be used when addressing this concern.

5. Reliable earthing (grounding) — Maintain reliable grounding of rack-

mounted equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (e.g. use of power strips).

Rack mounting

To rack mount the ISM 824, use two screws on each end of the switcher to attach the
switcher to the rack (see figure 2-1).

Cabling and RJ-45 connector wiring

It is vital that the Ethernet cables used be the correct type of cable, 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' (100 m).

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

Terminating the network cable

The cable can be terminated as either a patch cable or a crossover cable (figure 2-4)
and must be properly terminated relevant to the 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.

Figure 2-4 — RJ-45 connector pinout tables

Reset button and LED — Pressing this recessed button causes

d

certain IP functions and Ethernet connection settings to be reset
to the factory defaults. The green LED above the button blinks a

varying number of times to indicate which reset mode has been entered.

See chapter 3, “Operation and Setup”, “Resetting the unit with the reset
button” section, for information on reset modes.
