About the Switcher

The ISS 408 is an eight-input, scaling, video and stereoor mono audio seamless
switcher. Figure 1-1 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.

ISS 408 Integration Seamless Switcher • Introduction1-2

Several of the output resolutions and rates include Extron’s Accu-RATE Frame

m

™

(AFL™), a proprietary technology that locks the output frame rate to the

Lock
input rate, 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 1-1 — 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.

1-3ISS 408 Integration Seamless Switcher • Introduction

Introduction, cont’d

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.

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 3-11.

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 input frame rate.

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.

ISS 408 Integration Seamless Switcher • Introduction1-4

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.

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 selected for individual
inputs as desired or it can be set to automatically size and center each new
input selection.

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"

wide rack.

Installation

Mounting the Switcher

Four uninstalled rubber feet are included with the switcher. If you are going to
rack mount the switcher, mount it before you cable it (see “Rack mounting”,
below), and do not install the rubber feet. If you are not rack mounting the
switcher, 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 switcher.

Rack mounting

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the
installation of the switcher into a rack (figure 2-1).

1. Elevated operating ambient temperature — If the equipment is 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 switcher in an environment compatible with the
maximum ambient temperature (Tma = +122 °F, +50 °C) specified 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).

Patch (straight) cable

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, 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 your network speed. The ISS 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.

Wiring the network cable

The cable can be terminated as either a patch cable or a crossover cable (figure 2-8)
and must be properly terminated for your application:

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.

• 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

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
(figure 3-4). 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.

RGB Delay submenu

The RGB Delay submenu displays and lets you set the RGB delay when switching a
selected input to the preview output. With RGB delay, sync is never removed from
the preview display. Rather, the ISS blanks the RGB (video) outputs while the
scaler locks to the new sync, and then switches the RGB signals. This allows a brief
delay for the displays to adjust to the new sync timing before displaying the new

Auto Imaging and Auto Memories submenu

The Auto Imaging and Auto Memories menu provides a means to turn the auto
imaging and auto presets features on or off for all input selections.

If auto imaging is set to on, the ISS automatically sizes and centers the selected
input to fill the screen when a new frequency is input. If auto imaging is set to off,
the ISS sizes and centers the selected input only when it is commanded using the
input button. See “Auto imaging an input”, earlier in this chapter. Rotate the

The auto memories feature saves and recalls centering, sizing, and filtering
information, based on the input frequency. Auto memory settings may conflict
with user preset settings. When you use a control system to switch inputs and then
recall a user memory, the delay in recalling the auto memory settings could result
in the recalled auto memory settings overwriting the recalled user memory settings.
To prevent this conflict, turn auto memories off. Rotate the Adjust
auto memories on or off.

Enhanced Mode submenu

The Enhanced Mode submenu provides a means to turn enhanced mode on or off.
Enhanced mode is an automatic gain control for S-video or composite video input
signals scaled and applied to the program output. If the input signal level is too
weak, the signal gain is increased; if the input signal level is strong, the signal gain
is decreased.

Pixel Phase submenu

The Pixel Phase submenu displays and lets you set the pixel phase, which is the
timing of the digital scaler’s sampling. Sampling at the optimum pixel phase
results in a brighter scaled output.

Use either the Adjust
outputs simultaneously from 0 to 31. The default is 16.

Preview Switch Mode submenu

The Preview Switch Mode submenu lets you set the way the preview output
responds to the cut or dissolve operation.

• Stay mode — When you initiate either a cut or dissolve operation, the video

and audio signals on the preview output are applied to the program output
(figure 3-14) and also continue to be applied to the preview output until
another input is selected.

The video input switches between the switcher’s two internal scalers,
resulting in a switching report being issued on the RS-232 port (see
“Switcher-Initiated Messages” in chapter 4, “Operation”).

• Swap mode — When you initiate either a cut or dissolve operation, the

preview and program outputs are swapped (figure 3-14). The video and
audio signals on the preview output are applied to the program output. The
video and audio signals that had been applied to the program output are
applied to the preview output.

Each of the switcher’s two internal scalers retains the same video inputs; only
the outputs are swapped. No switching report is issued on the RS-232 port

IP information

To set up the ISS for operation via its Ethernet port, you need to know and be able
to change the IP address. One way to do this is via the IP address and hardware
address screen.

To access the IP address and hardware address screen, press and hold the
Color/Tint and Detail buttons while you apply power to the ISS (figure 3-19).
When the ISS is finished intializing, it displays both addresses.

Figure 3-19 — IP information flowchart

If you need to change the IP address, use the Adjust knob to select the desired
subfield. Rotate the Adjust knob to change the value. Repeat the adjustment for
other subfields as required.

Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by
dots (periods). Each field can be numbered from 000 through 255. Leading zeroes,
up to three digits total per field, are optional. Values of 256 and above are invalid.

If the local system administrators have not changed the value, the factory­specified default, 192.168.254.254, is the correct value for this field.

The hardware address is hard-coded and cannot be changed.

Optimizing the Video

Perform the following steps, in sequence, after you have installed the ISS. This
procedure will help you to configure the switcher for the best settings for your
display environment. In a multi-screen environment, perform this procedure for
each display.

See “Advanced Configuration menu”, earlier in this chapter, to select and output a
test pattern and to select and output blue-only video.

See “Picture adjustments”, earlier in this chapter, to make adjustments to the
picture quality.

See “User Presets menu”, earlier in this chapter, to save presets.

ISS 408 Integration Seamless Switcher • Operation3-20

1. If you are using a digital display, such as an LCD or DLP projector, use the

alternating pixels test pattern as a reference to adjust the phase and dot clock
on the display devices. Proceed to step 3.

If you are using a CRT display, use the cross hatch test pattern as a reference
to converge the display.

2. Set the ISS to output either the crop test pattern for 4:3 video or the

appropriate aspect ratio test pattern.

3. Use the display’s positioning controls to position the image so that you can

see all sides of the test pattern on the display.

For the best results of this optimizing procedure, do not use the ISS’s centering
controls to position the image.

4. Select an input. Use the ISS’s size and center functions to fill the crop or

aspect ratio test pattern.

If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio
before sizing the image using the ISS’s size function to correct the aspect ratio.
See “Setting up a DVD source”, below.

When you are sizing and centering a letterbox movie video source, increasing
the brightness on the ISS makes it easier to see the top and bottom of the active
video.

5. If the input source is RGB, use the horizontal and vertical detail adjustments

to increase the sharpness.

6. For S-video and composite video inputs, set the ISS to output blue-only

video and to output the Color Bars test pattern. Using the blue Color Bars as
a reference, use the ISS’s color and tint controls to adjust the video’s color and
tint.

7. For RGB video inputs, set brightness and contrast levels. See “Picture

adjustments”, earlier in this chapter.

8. Save this setting into one of the user memories using the User Presets menu.

See “User Presets menu”, earlier in this chapter.

Setting up a DVD source

To get the best results when using a DVD as a video source, Extron recommends
that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3.
Because all DVDs are mastered as 16:9, having them set up for anything else causes
the player to internally scale and compress the signal. The DVD player’s scaling
and compression defeats the advantage of having 3:2 pulldown detection in the ISS.

All sizing adjustments to correct aspect ratio should be done using the ISS.
To change the output aspect ratio of most DVD players:

1. Enter the DVD player’s setup or action menu while the disc is stopped.

2. Select the 16:9 aspect ratio.

3-21ISS 408 Integration Seamless Switcher • Operation

Operation, cont’d

Optimizing the Audio

Each individual input audio level can be adjusted within a range of -24 dB to +9 dB,
so there are no noticeable volume differences between sources and for the best
headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as
follows:

1. Connect audio sources to all desired inputs and connect the audio outputs to

output devices such as audio players. See “Input connections” and “Standard
output connections”, in chapter 2, “Installation”. For best results, wire all of
the inputs and the outputs unbalanced.

2. Power on the audio sources, the switcher, and the audio players.

3. Switch among the inputs (see “Selecting an input and switching it to the

program output”, earlier in this chapter), listening to the audio with a critical
ear or measuring the output audio level with test equipment, such as a VU
meter.

4. As necessary, adjust the audio level of each input (see “V ideo & Audio

Configuration menu”, earlier in this chapter) so that the output level is
approximately the same for all selected inputs.

Troubleshooting

The following tips may help you in troubleshooting.

• Some symptoms may resemble others, so you may want to look through all
of the examples before attempting to solve the problem.

• Be prepared to backtrack in case the action taken does not solve the problem.

• It may help to keep notes and sketches in case the troubleshooting process
gets lengthy. This will also give you something to discuss if you call for
technical support.

• Try simplifying the system by eliminating components that may have
introduced the problem or made it more complicated.

• For sync-related problems: Portable digital projectors are designed to operate
close to the video source. Sync problems may result from using long cables
or from improper termination. A sync adapter, such as Extron’s ASTA (active
sync termination adapter), may help solve these problems.

• For LCD and DLP projectors and plasma displays: In addition to the sync­related information above, check the user’s manual that came with the
projector for troubleshooting tips, as well as for settings and adjustments.
Each manufacturer may have its own terms, so look for terms like “auto
setup”, “auto sync”, “pixel phase”, and “tracking”.

General checks

1. Ensure that all devices are plugged in and powered on. The switcher is

receiving power if the LCD is displaying the default display cycle.

2. Ensure that an active input is selected on the switcher.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

Switcher-Initiated Messages

When a local event such as power-up or a front panel operation occurs, the
switcher responds by sending a message to the host. The switcher-initiated
messages are listed in the following pages. The messages are underlined.

The switcher does not expect a response from the host; but the host program may
request a new status.

Host-to-Switcher Instructions

The switcher accepts SIS commands through its RS-232 port and/or its Ethernet
port. SIS commands consist of one or more characters per command field. They do
not require any special characters to begin or end the command character sequence.
Each switcher response to an SIS command ends with a carriage return and a line
feed (CR/LF =

), which signals the end of the response character string. A string

is one or more characters.

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the switcher is
unable to perform the command because the command is invalid or contains
invalid parameters, the switcher returns an error response to the host. The error
response codes are:

E01 — Invalid input channel number (too large)

E10 — Invalid command

E11 — Invalid preset number (too large)

E12 — Invalid output number (too large)

E13 — Invalid value (out of range)

Using the Command/Response Table

The command/response table begins on the next page. Except for the gain and
attenuation settings and the filter settings, upper or lower case letters are acceptable
in the command field. The table below shows the hexadecimal equivalent of each
ASCII command.

With the exception of the audio gain and attenuation (G and g) and horizontal
and vertical filtering (D and d) commands, the SIS commands are not case
sensitive.

Take (switch preview output to program output)

The cut or dissolve effect is determined by the Switching Effect,

X29

(0 = cut, 1 = dissolve) *4#

command. See “Command/Response Table for Special Function SIS Commands”.
The preview switch mode, stay or swap, determines the preview output after the take command.

• In stay mode, the preview output remains unchanged (both outputs share the same input).

• In swap mode, the program output switches to the preview output (the two outputs swap inputs).

Switch video and audio % Tke0 Switch preview video and audio

output to the program output.

Switch video only 1% Tke1 Switch preview video output to

the program output.

Switch audio only 2% Tke2 Switch preview audio output to

the program output.

The response (Tke0 , Tke1 , or Tke2 ) indicates that the switcher has received and is responding
to the “Take” command. A larger series of switcher-initiated messages follows the Tke response
during a cut or dissolve operation. The following two examples show the sequence of responses to a
“Take” command in stay and swap mode. See Busy (cut and dissolve) earlier in this chapter for
more details about the responses after the Tke response.

Switcher Software

Control Software for Windows

The Windows-based Extron ISSISM Control Program communicates with the
switcher via the Ethernet LAN port or the rear panel Remote RS-232/RS-422 port to
provide an easy way to set up and operate the switcher. The program is compatible
with Windows 2000 and Windows XP. Updates to these programs can be
downloaded from the Extron Web site (http://www.extron.com).

Installing the software

The program is contained on the Extron Software Products CD-ROM. Install the
software as follows:

1. Insert the CD-ROM into the drive. The installation program should start

automatically. If it does not self-start, run Launch.exe from the CD.
The Extron software CD window appears (figure 5-1).

®

Figure 5-1 — Software CD window

2. Click the Software tab (figure 5-1).

3. Scroll to the desired pr ogram and click Install (figure 5-2).

Figure 5-2 — Software installation

ISS 408 Integration Seamless Switcher • Switcher Software5-2

4. Follow the on-screen instructions. By default, the installation of the

installation routine creates a C:\Program Files\Extron\ISSISM directory, and
it places the following five icons into a group folder named “Extron
Electronics\ISSISM”:

• Button-Label Generator-

• Check for ISSISM Control Program Update

• ISSISM Control Program

• ISSISM Help

• Uninstall ISSISM Control Program

Software operation via Ethernet

When an ISS is connected to an Ethernet WAN or LAN, any number of users can
operate it, locally or remotely, using the ISS/ISM Control Program. See “Ethernet
connection” in chapter 2, “Installation”, for installation details

Connection to the switcher via the Ethernet is password protected. There are two
levels of password protection: administrator and user. Administrators have full
access to all ISS switching capabilities and editing functions. Users can select video
and/or audio for output, select inputs and outputs, select test patterns, set RGB
and audio mutes, select a blue screen, and view all settings with the exception of
passwords. If the same passwords or no password is required for logging on, all
personnel log on with administrator privileges. Fields and functions that exceed
user privileges are grayed out in the ISS/ISM Control Program when the operator
is logged on as a user.

Ethernet protocol settings

The IP Settings/Options screen (figure 5-8 on page 5-6) provides a location for
observing and, if you are connected via the RS-232 link or if logged on via the
Ethernet port as an administrator, editing settings unique to the Ethernet interface.
None of the fields on this screen can be edited while you are logged on as a user.
See “System Configuration Page” in chapter 6, “Ethernet Operation”, for details on
the contents of these fields. See appendix A, “Ethernet Connection”, for other basic
information about Internet protocol.

Editing variables on the IP Settings/Options screen while connected via the
Ethernet port can immediately disconnect the user from the ISS. Extron
recommends editing the settings on this screen using the RS-232 link and
protecting the Ethernet access to this screen by assigning an administrator’s
password to qualified and knowledgeable personnel only.

Ethernet Operation

The ISS 408 can be controlled and operated through its Ethernet port, connected via
a LAN or WAN, using a Web browser such as the Microsoft
This chapter describes the factory-installed HTML pages, which are always
available and cannot be erased or overwritten.

If your Ethernet connection to the ISS is unstable, try turning off the proxy
server in your Web browser. In Internet Explorer, click Tools > Internet

Options > Connections > LAN Settings, uncheck the “Use a proxy
server...” box, and then click Ok.

Loading the Startup (Control) Page

Access the switcher using HTML pages as follows:

1. Start the Web browser program.

2. Click in the browser’s Address field.

3. Type the switcher’s IP address in the browser’s Address field.

If the value has not been changed, the factory-specified default,

192.168.254.254, is the correct value for this field.

4. If you want the browser to display a page other than the default page (such as
a custom page that you have created and uploaded), enter a slash (/) and the
name of the file to open.

The browser’s Address field should display the address in the following format:

xxx.xxx.xxx.xxx/{optional_file_name.html}
The following characters are invalid in file names: {space} ~ @ = ‘ [ ] { }

< > ’ “ ; : | \ and ?.

5. Press the keyboard Enter key. The switcher checks to see if it is password

6. Click in the Password field and type in the appropriate administrator or user
password.

ISS 408 Integration Seamless Switcher • Ethernet Operation6-2

7. Click OK. The switcher checks several possibilities, in the following order,

and then responds accordingly.
a. Does the address include a specific file name, such as

10.13.156.10/file_name.html? If so, the switcher downloads that HTML
page.

b. Is there a file in the switcher’s memory that is named “index.html”?

If so, the switcher loads “index.html” as the default startup page.

c. If neither of the above conditions is true, the switcher loads the factory-

installed default startup page, “nortxe_index.html” (figure 6-2), also
known as the Control page.

• Ethernet connection to the switcher, either by entering SIS commands via
Telnet (see chapter 4, “Programmer’s Guide”) or using the control program
(see chapter 5, “Switcher Software”) is password protected.

• Connection via Web pages and connection via the RS-232 port are not
password protected.

ISS 408 Integration Seamless Switcher • Ethernet Operation6-6

Access to the ISS settings using Web control is not password protected.
Ensure only knowledgeable and qualified personnel have access to the switcher
under Web control.

On password-protected connections, there are two levels of protection:
administrator and user. Administrators have full access to all ISS switching
capabilities and editing functions. Users can select video and/or audio for output,
select test patterns, set RGB and audio mutes, select a blue screen, and view all
settings except passwords.

Passwords are case sensitive and are limited to 12 upper case and lower case
alphanumeric characters. Each password must be entered twice: once in the
password field and then repeated in the re-enter password field. Characters in
these fields are masked by asterisks (*****). If you do not want to password-protect
an access level, leave the password field and the re-enter password field blank.
After entering the desired password in both fields, click the Submit button.

The program will not allow you to create a user password unless you have
already created an administrator password.

If a password has been inadvertently changed to an unknown value, you can
still connect to the switcher via the RS-232 link, which is not password
protected. When connected via the RS-232 link, using either SIS commands
(see chapter 4, “Programmer’s Guide”) or under program control (see chapter
5, “Switcher Software”), you can look up and, if desired, change a password.

ISS IP Settings fields

The ISS IP Settings fields provide a location for observing and editing settings
unique to the Ethernet interface. After editing any of the settings on this page, click
the Submit button.

ISS IP Address field

The ISS IP address field contains the IP address of the connected ISS. This value is
encoded in the flash memory on the controller circuit board.

Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by
dots (periods). Each field can be numbered from 000 through 255. Leading zeroes,
up to 3 digits total per field, are optional. Values of 256 and above are invalid.

The default address is 192.168.254.254, but if this conflicts with other equipment at
your installation, you can change the IP address to any valid value.

ISS Name field

The ISS name field contains the name of the switcher. This is helpful in identifying
the switcher in multiple-unit networks. This name field can be changed to any
valid name, up to 12 alphanumeric characters.

Hardware Address field

The hardware address (also known as the MAC address) is hardcoded on the
controller board and cannot be changed.

• For output resolutions with less than 1024 pixels horizontally, the
optional DVI program output’s true horizontal resolution is limited to
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 program output’s true horizontal resolution is limited to 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, meaning that the DVI output fully supports the selected
horizontal and vertical resolution. The DVI output resolution for these
rates exactly matches the analog resolution.

Installing a DVI Output Card

You can install an optional digital visual interface (DVI) output card in the ISS.
With the card installed, an additional program output is available as DVI video
on a standard DVI connector. This program output is in addition to the standard
RGB video on BNC connector and 15-pin HD connectors. Extron recommends
that you send the unit to Extron for service and updates.

Install an optional DVI output card in the ISS as follows:

Changes to electronic components must be performed by authorized
service personnel only.

To prevent electric shock, always unplug the ISS from the AC power
source before opening the enclosure.

1. Open the switcher. See “Opening and Closing the Switcher” on page 7-2.

CAUTION

2. Locate the DVI output card connector opening on the rear panel and the
DVI output card connector J14. When viewed from the front, connector J14
is in the far left corner of the main circuit board (figure 7-3).

Do not touch any switches or other electronic components inside the ISS.

To access the ISS switcher via the Ethernet port, you need the Extron ISS IP address.
If the address has been changed to an address comprised of words and characters,
the actual numeric IP address can be determined using the Ping utility. If the
address has not been changed, the factory-specified default is 192.168.254.254.

Ping can also be used to test the Ethernet link to the ISS.

Pinging to determine the switcher’s IP address

The Microsoft Ping utility is available at the DOS prompt. Ping tests the Ethernet
interface between the computer and the ISS. Ping can also be used to determine the
actual numeric IP address from an alias and to determine the Web address.

Access the DOS prompt and ping the switcher as follows:

1. Click Start > Run.

2. At the Open prompt, type command.

3. Click the OK button.

4. At the DOS prompt, type ping {IP address} and press the keyboard

Enter

Enter key (
The line Pinging ... reports the actual numeric IP address, regardless of

whether you entered the actual numeric IP address or an alias name.

). The computer returns a display similar to figure A-2.

Figure A-2 — Ping response

Pinging to determine Web IP address

The Ping utility has a modifier, -a, that directs the command to return the Web
address rather than the numeric IP address.

At the DOS prompt, type ping -a {IP address} and then press the keyboard
Enter key. The computer’s return display is similar to the Ping response shown in
figure A-2, except that when you specify the -a modifier, the line Pinging mail...
reports the Web IP address rather than the numeric IP address, regardless of
whether you entered the actual numeric IP address or an alias name.

Telnet tips

It is not the intention of this manual to detail all of the operations and functionality
of Telnet; however, some basic level of understanding is necessary for operating the
ISS via Telnet.

Open

Connect to the ISS using the Open command. Once you are connected to the
switcher, you can enter the SIS commands the same as you would if you were using
the RS-232 link.

Connect to the ISS as follows:

1. At the Telnet prompt, type open {IP address} and then press the

keyboard Enterkey.
If the switcher is not password protected, no further prompts are displayed

until you break or disconnect the connection to the ISS.

If the switcher is password protected, Telnet displays the password prompt.

2. If necessary, at the password prompt, type the appropriate password and then

press the keyboard Enterkey.
Connection to the switcher via the Ethernet can be password protected. There

are two levels of password protection: administrator and user. A person
logged on as an administrator has full access to all ISS switching capabilities
and editing functions. Users can select video and/or audio for output, select
test patterns, set RGB and audio mutes, select a blue screen, and view all
settings with the exception of passwords. By default, the ISS is shipped with
no password assigned.

ISS 408 Integration Seamless Switcher • Ethernet ConnectionA-4

Once you are logged in, the ISS returns either Login Administrator or
Login User. No further prompts are displayed until you break or disconnect

the connection to the ISS.

Escape character and Esc key

When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’.

Esc

Many SIS commands include the keyboard

key. Consequently, some confusion

may exist between the Escape character and the Escape key.

Ctrl

The Telnet Escape character is a key combination, the

key and the ] key
pressed simultaneously, that returns you to the Telnet prompt while leaving the
connection to the ISS intact.

Esc

The Escape key is the

key on the computer keyboard.

Local echo

Once the computer is connected to the ISS, by default Telnet does not display your
keystrokes on the screen. SIS commands are typed in blindly and the SIS responses
are displayed on the screen. To command Telnet to show keystrokes, type set

Enter

local_echo at the Telnet prompt, and then press

before you open the

connection to the switcher.
With local echo turned on, keystrokes and the switcher’s response are displayed on

the same line. For example: 1*1!In1 Out1 All, where 1*1! is the SIS command and
In1 Out1 All is the response.

With local echo turned on, all keystrokes are displayed, even those that should be
masked, such as the password entry. For example, when entering a password with
local echo turned on, you see a display such as a*d*m*i*n*, where admin is the
keyed in password and ***** is the masked response.

Local echo can be turned off by typing unset local_echo and then pressing

Enter

at the Telnet prompt. If you are connected to the ISM and need to access the

Telnet prompt to turn local echo off, type the Escape character (

Ctrl

+]).

Set carriage return-line feed

Unless commanded otherwise, Telnet transmits a line feed character only (no
carriage return) to the connected ISS when you press the

Enter

key. This is the

correct setting for SIS communication with the switcher. The Telnet set crlf
command forces Telnet to transmit carriage return and line feed characters when

Enter

is pressed, but if crlf is set, the SIS link with the switcher will not function

properly. Do

not set crlf on. If necessary, issue the unset crlf command to turn

off crlf.

Close

To close the link to the switcher, access the Telnet prompt by typing the Escape

Ctrl

character (

+]). At the Telnet prompt, type close and then press

Help

For Telnet command definitions, at the Telnet prompt, type ? and then press
