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

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.

Test Pattern submenu

The Test Pattern submenu lets you select from among several test patterns and assign the selected pattern to an output. The test patterns are helpful when adjusting the connected displays for color, convergence, focus, resolution, contrast, grayscale, and aspect ratio.

Use the Adjust knob to select a test pattern. The options are: Color Bars, crosshatch, 4x 4 crosshatch, grayscale, crop, alternating pixels, film aspect ratios 1.78, 1.85, 2.35, and ramp.

Use the Adjust knob to assign the output(s) for the selected test pattern. Select among neither output (both off), output 2, output 1, or both outputs.

Blue-Only Mode and Edge Smoothing submenu

The Blue-Only Mode and Edge Smoothing submenu lets you turn the blue mode and edge smoothing features on and off. Blue-only mode is helpful in the setup of the color and tint of the incoming video signal. In the blue-only mode, only the sync and blue video signals are passed to the display. Edge enhancement mode smooths edges of a picture by minimizing the differences between pixels.

Use the Adjust knob to assign Blue-Only Mode to neither output (both off), output 2, output 1, or both outputs. The default is Off.

Use the Adjust knob to assign Edge Smoothing to neither output (both off), output 2, output 1, or both outputs. The default is Off.

Blanking submenu

The Output Blanking submenu displays and allows you to adjust the top and bottom line blanking on the output monitors within a range of 0 to 200 lines. During scaling, captioning and tapehead switching in the video’s blanking area may show up as picture noise. Using blanking, you can add black lines at the top and bottom edges of the image to eliminate edge noise.

Select the output that you want to blank by pressing the desired Output button.

Use the Adjust knob to increase or decrease the top line blanking. The default is 0 lines.

Use the Adjust knob to increase or decrease the bottom line blanking. The default is 0 lines.

RGB Delay submenu

The RGB Delay submenu displays and lets you set the RGB delay when a switch is made. With RGB delay, sync is never removed from the display. Rather, the ISM 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 picture, which appears without glitches. RGB delay is also known as Triple-Action Switching™ or video mute switching.

Use the Adjust knob to select the blanking period (RGB delay time) for output 1 from 0 seconds to 5 seconds in 0.1 second steps. The default is 0.2 seconds.

Use the Adjust knob to select the blanking period for output 2.

ISM 482 Integrated Scaling Matrix Switcher • Operation 21

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 globally.

If auto imaging is set to on, the ISM 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 ISM automatically sizes and centers the selected input only when it is commanded using the input button (see

Auto imaging an input on page 14). Rotate the Adjust knob to toggle auto imaging on

or off for all input selections.

The auto memories feature saves and recalls centering and sizing information, based on the input frequency. With some control systems, the delay involved in recalling the memory can be a problem, so it may improve system performance to turn auto memories off. Rotate the Adjust knob to toggle 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 an 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.

Use either the Adjust or Adjust knob to turn on enhanced mode for neither output (off for both), output 2, output 1, or both outputs. The default is Off for both.

NOTE: Enhanced mode is effective only for S-video and composite video input signals.

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 the Adjust knob to select the pixel phase for output 1 from 0 to 31. The default is 16.

Use the Adjust knob to select the pixel phase for output 2.

PAL Film Mode submenu

The PAL Film Mode submenu lets you turn PAL film mode on and off for the selected input. The PAL film mode should be used for a video source that is PAL video that originated from film. PAL film mode applies video processing algorithms that optimize the conversion of video that was made with the 2:2 pulldown (PAL video from film) process.

Use either the Adjust knob or the Adjust knob to select On or Off. Select other inputs as necessary to configure.

Reset submenu

The Reset submenu resets all ISM 482 settings and adjustments to the default values and erases all presets. The front panel reset performs the same functions as the EzXXX] SIS command on page 43.

Reset the switcher by pressing and holding the Black/Mute button while this submenu is active. The LCD displays Unit Reset to Factory Defaults when the reset is complete. Release the Black/Mute button.

Optimizing the Video

Perform the following steps, in sequence, after you have installed the ISM. 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 on page 20, to select and output a test pattern and to select and output blue-only video.

See Picture Adjustments on page 25, to make adjustments to the picture quality.

See User Presets menu on page 23, to save presets.

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 ISM 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.

NOTES:

• If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio

Presets menu on page 23).

the brightness on the ISM makes it easier to see the top and bottom of the active video.

ISM 482 Integrated Scaling Matrix Switcher • Operation 28

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 ISM.

All sizing adjustments to correct the aspect ratio should be done using the ISM.

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.

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 on page 6 and Standard

output connections on page 8). 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 on page 13), 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 Video & Audio Configuration

menu on page 17) 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 the Extron ASTA (active sync termination adapter), may help solve these problems.

• For LCD and DLP projectors and plasma displays: In addition to the sync-

related 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.”

ISM 482 Integrated Scaling Matrix Switcher • Operation 29

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 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 S3 Sales & Technical Support Hotline if necessary.

Host-to-Switcher Instructions

ASCII to Hex Conversion Table

•

Space

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 (zero or too large)

E12 — Invalid output number (zero or too large)

E13 — Invalid value (out of range)

Using the Command and 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.

NOTE: With the exception of the audio gain and attenuation (G and g) and horizontal

Switcher Software

This section describes

• Control Software for Windows

• Button-Label Generator

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 DVD. Install the software as follows:

1. Insert the DVD into the drive. The installation program should start automatically. If it

does not self-start, run Launch.exe from the DVD.

The Extron software DVD window appears (see figure 28).

Figure 28. Software DVD Window

2. Click the Software tab (see figure 28, a).

ISM 482 Integrated Scaling Matrix Switcher • Switcher Software 47

3. Scroll to the desired program and click Install (see figure 29).

Figure 29. Software Installation

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 ISM 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 on page 9 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 ISM 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 (see figure 35 on page 51) 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 on page 67, for details on the contents of these fields. See Ethernet Connection on page69 for other basic information about Internet protocol.

NOTE: Editing variables on the IP Settings/Options screen while connected via

the Ethernet port can immediately disconnect the user from the ISM. 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.

ISM 482 Integrated Scaling Matrix Switcher • Switcher Software 48

Using the Control Program

Many items found in the ISS/ISM Control Program are also accessible via front panel controls and the LCD menus (see the Operation section, starting on page 15), and under SIS control (see the Programming Guide section, starting on page 38). The ISS/ISM Help Program provides information on settings and on how to use the control program, itself.

1. To run the control program, click Start > Programs > Extron Electronics >

ISSISM.

Figure 30. Comm Port Selection Window

2. Select the comm port that is connected to the ISM’s Remote port or select IP [LAN] and

click OK.

• If you selected a comm port, proceed to step 5.

The ISM 482 scales the input signal up or down to any of a number of output resolutions and rates. The switcher outputs the scaled video as RGBHV or RGBS, with user-selectable polarity, via either the program or preview connectors. The table below shows the resolutions and rates available on the ISM 482.

NOTES:

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

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

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

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

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

Connect to the ISM as follows:

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

• If the switcher is not password protected, no further prompts are displayed

until you break or disconnect the connection to the ISM.

• 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

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 ISM 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 ISM is shipped with no password assigned.

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

When Telnet is first started, the utility advises that the Escape character is ‘Ctrl+]’. Many SIS commands include the keyboard

key. Consequently, some confusion may exist

between the Escape character and the Escape key.

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 ISM intact.

The Escape key is the

key on the computer keyboard.

Local echo

Once the computer is connected to the ISM, 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 local_echo at the Telnet prompt, and then press

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 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 (
