About this Manual

This manual contains installation, configuration, and operating information for the Extron ISS 408 Integration Seamless Switcher.

In this manual, the terms “switcher” and “ISS” are used interchangeably to refer to the ISS 408.

About the Switcher

The ISS 408 is an eight-input, scaling, video and stereo or mono audio seamless switcher.

Figure 1, on the next page, shows a typical ISS 408 application. The switcher accepts 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. The ISS seamlessly switches among the input sources without a loss of sync. The ISS can also mask the switch between sources with a dissolve effect for a professional look.

Each video input is individually configurable to allow for different video formats. The ISS 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, plasma display, or digital visual interface (DVI) device.

The ISS provides two separate outputs: the program output and the preview output. The program output is the picture the audience sees. The preview output allows the switcher operator to view the image before it is sent to the program output. With an optional DVI output card, the ISS converts the scaled image to DVI as an additional program output.

The switcher inputs all valid video signal formats on eight sets of five BNC connectors. The ISS 408 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 (program and preview) of connectors. The program and preview outputs each consist of five BNC connectors 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 ISS 408 features HDTV 576p, 720p, 1080p, and 1080i outputs.

Figure 1. Typical ISS 408 Integration Seamless Switcher Application

The ISS receives and outputs audio on 5-pole captive screw connectors. The audio can be switched with cross fading; the previous audio channel fading out and the new audio channel fading in.

For upscaling, the ISS 408 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 ISS 408 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, plasma projectors, and (with an optional DVI card) a DVI display or projector.

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

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

ISS 408 Integrated Seamless Switcher • Introduction 2

Features

• Inputs —

• Video inputs — The ISS 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 ISS switches among eight balanced or unbalanced stereo or

mono audio inputs on 5-pole captive screw connectors.

• Outputs —

• Standard video outputs — The ISS 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 program image, and the other set of BNC connectors and 15-pin HD connector display the preview 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 program output image.

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

optional DVI program output’s true horizontal resolution is limited to 1024 pixels. For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI program 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 ISS outputs the selected unamplified, line level, balanced or

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

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

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 and 2:2 film detection for PAL video

sources — 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 ISS’s advanced film mode processing recognizes signals that originated from film. The ISS 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 are no noticeable volume differences between sources.

ISS 408 Integrated Seamless Switcher • Introduction 3

• Audio cross-fading — This transition technique is applied during switching to lower

the audio level of the switched out source while simultaneously raising the audio level of the activated source.

• 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.

• Transitions — Controls the type of switch that will occur between the preview and

program outputs. The Cut button creates an instant switch between the preview and program outputs. The Dissolve button switches with a dissolve effect.

• 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) (preview output) — RGB delay mutes the

R, G, and B video planes to blank the preview screen while the scaler locks to the new sync, so that a noise-filled scramble is not shown on the preview 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 8 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 ISS 408 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 settings for

color, tint, contrast, brightness, detail, size, and centering.

• 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 ISS function as a still store.

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

wide rack.

• For unbalanced audio, connect the sleeves to the ground contact. DO NOT

connect the sleeves to the negative (-) contacts.

• The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).

• If the stripped section of wire is longer than 3/16 inch, the exposed wires

may touch, causing a short circuit between them.

• If the stripped section of wire is shorter than 3/16 inch, wires can be easily

pulled out even if tightly fastened by the captive screws.

ISS 408 Integrated Seamless Switcher • Installation 8

By default, the audio output follows the video switch. Audio breakaway, commanded via the front panel, the Ethernet link, or the RS-232 link, allows you to select from any one of the audio input sources. See the applicable portions of the “Operation” section (see page 14), “Programming Guide” section (see page 41), “Switcher Software” section (see page 54), and “HTML Operation” section (page 59).

Optional Output Connection

h DVI output connector (optional) — If the optional DVI output card is installed,

connect a DVI/DFP-compatible video display to this DVI connector. This connector outputs the program image only.

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

horizontal resolution of the optional DVI program output is limited to 1024 pixels. For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI program 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

i 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 properly terminated with the correct pinout.

Choosing a network cable

Ethernet links use Category (CAT) 3, 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).

NOTE:

• Do not use standard telephone cables. Telephone cables do 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 ISS supports both 10 Mbps (10Base-T — Ethernet) and 100 Mbps (100 Base-T — Fast Ethernet), half-duplex and fullduplex, Ethernet connections.

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

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

ISS 408 Integrated Seamless 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 through) cable — Connection of the ISS to an Ethernet hub, router,

or switcher that also hosts a controlling computer

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

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

Power-on Indications

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 inputs previously selected for the preview output (blinking LED[s]) and program output (solid LED[s]). The self-test also displays the model name, part number, and the firmware version in the LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle, alternating between two displays: one showing the selected program and preview inputs and their rates, and the other showing the selected output rate (see figure 14). An error-free power up self-test sequence leaves all of the LEDs off, with the exception of the selected input’s LED, and the LCD cycling through the default displays.

The selected preview and program inputs, the picture adjustments, and other current settings are saved in nonvolatile memory. When power is applied, the latest configuration is retrieved.

NOTE: On figure 14 and all other flowcharts in this chapter, solid lines indicate screen

changes initiated by the operator. Dashed lines indicate screen changes that are the result of a timeout function.

NOTES:

• For output resolutions with less than 1024 pixels horizontally, the optional

DVI output is limited to a true horizontal resolution of 1024 pixels. The vertical resolution is the selected vertical resolution. For these resolutions, the ISS DVI output is 1024 x {selected vertical size}. For example, if the output resolution is set to 640 x 480, the DVI output card’s actual resolution is 1024 × 480.

• For the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI output

is limited to a true horizontal resolution of 1280 pixels. For these resolutions, the ISS DVI output is 1280 x {selected vertical size}. For example, if the output resolution is set to 1080p, the DVI output card’s actual resolution is 1280 x 1080.

• The DVI card outputs all other selected resolutions normally.

• Resolutions marked with an asterisk (*) in the table above are native DVI outputs;

the DVI output fully supports the selected horizontal and vertical resolution. The DVI output resolution for these rates exactly matches the analog resolution.
