Introduction

About this Manual

This manual contains installation, configuration, and operating information for the Extron IN1508 Scaling Presentation Switcher (referred to in this manual as the “IN1508” or the “switcher”).

• Chapter 1 identifies the switcher’s features.

• Chapter 2 details how to install the switcher.

• Chapter 3 describes how to operate the switcher from its front panel and use all of its features.

• Chapter 4 provides information about programming and operating the switcher under RS-232 control, such as from a PC or host controller. You can control the switcher using the Simple Instruction Set (SIS

• Appendix A lists the switcher’s specifications and pertinent part numbers.

About the Switcher

The Extron IN1508 is an eight-input video and stereo audio switcher that incorporates a video scaler (figure 1-1). The switcher accepts:

• Two NTSC/PAL/SECAM/NTSC 4.43 composite video inputs on female BNC connectors

• Two S-video (Y/C) inputs on 4-pin mini DIN connectors

• One component (YUV) video input (progressive [Y, B-Y, R-Y] or interlaced [Y, B-Y, R-Y]) on female BNC connectors

• Two VGA – UXGA (RGBHV or RGBS) inputs on 15-pin HD connectors

• One digital visual interface (DVI), direct digital input on a DVI-I female connector (see “DVI video” in this chapter for an introduction to the DVI video format)

™

) commands.

With the proper adapters, the IN1508 can also be used with High Definition Multimedia Interface (HDMI™) signals.

• Eight unbalanced stereo or mono audio inputs (five inputs on RCA connectors and three inputs on 3.5 mm mini stereo jacks)

The IN1508 scales the video inputs to a variety of standard VGA and HDTV resolutions and any of up to 3 available refresh rates. The switcher outputs RGBHV, RGBS, RGsB, or progressive component (Y, B-Y, R-Y) video on a 15-pin HD (VGA) connector. It outputs stereo or mono audio on left and right RCA connectors and a 3.5 mm 5-pole captive screw connector. The IN1508 allows all of the input formats listed above 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 IN1508 seamlessly switches between the VGA and low-resolution video inputs. Seamless switching allows switching between sources without a loss of sync.

The switcher’s scaler upscales or downscales, converting the horizontal and vertical sync timing and the number of lines of the video input to match the native resolution of the display. This produces an undistorted, brighter picture.

The switcher is housed in a 1U high, 17.5" wide metal enclosure. With the included mounting ears, the switcher is rack-mountable. With optional mounting hardware, the switcher can be mounted under or through furniture or other mounting surface. The switcher has an internal 100 VAC to 240 VAC, 50/60 Hz, 40 watts, autoswitchable power supply that provides worldwide power compatibility.

DVI video

DVI is a digital transmission standard for high-speed, lossless video interfaces, such as between a computer and a direct digital monitor. The DVI standard, which Silicon Image Corporation also refers to as PanelLink and PanelLink Digital, specifies single link and dual link digital versions for either the digital only (DVI-D) or digital and analog combined (DVI-I) connectors. A single link supports resolutions higher than HDTV at a reduced blanking interval. The dual link configuration supports the higher bandwidth demands of displays that do not support reduced blanking. The IN1508 switcher supports a single link of DVI-D video.

DVI uses a process called transmission minimized differential signaling (TMDS) for sending graphics data to a compatible monitor. TMDS is based on an encoding algorithm that converts 8 bits of data into a 10-bit transition-minimized DC-balanced signal. The DVI standard, as supported by the switcher, allows for a single link of 3 channels (red, green and blue) of data, enabling the use of large pixel format digital display devices.

The IN1508 switcher converts direct digital video to analog RGB video. The switcher accepts a single link of DVI-D video from a computer or other digital video source device on a standard 25-pin female DVI-D connector. The Digital Flat Panel (DFP) video format can be input using a DFP-to-DVI adapter.

Standard DVI cable

DVI/DFP signals run at a very high frequency and are especially prone to bad video connections, too many adapters, or excessive cable length. To avoid the loss of an image or jitter, follow these guidelines:

• Do not exceed 16.4 feet (5 meters) on the switcher’s input when using standard DVI cables.

• Only use an input cable specifically designed for DVI signals.

• Limit or avoid the use of adapters.

• Use only approved DVI/HDMI connectors.

IN9700 cable

Extron’s IN9700 extension cable can be used to stretch the length of the input cable, so long as no adapters are used in the cable run. Use the following lengths as a guideline:

Extron’s IN9700 extension cable can be used to extend the length of the input cable. See “IN9700 cable”, below.

Use only cables specifically intended for DVI or HDMI interfaces. Use of non-DVI or non-HDMI cables or modified cables can cause the switcher to be unable to receive the DVI input.

Inputs —

Video inputs — The switcher switches among:

• Two fully-configurable RGB video inputs on 15-pin HD connectors

• One HDTV component video, interlaced component video, or progressive scan video on three BNC connectors

• Two S-video inputs on 4-pin mini-DIN connectors

• Two composite video inputs on single BNC connectors.

• One single link of DVI-D on a DVI connector with EDID emulation

Audio inputs — The switcher switches among eight unbalanced stereo audio

inputs, five inputs on left and right RCA connectors and three inputs on

3.5 mm mini stereo jacks. Inputs can come from sources such as a VCR, DVD player, computer audio card, or other audio device that outputs a stereo line-level signal.

Outputs —

Video outputs — The IN1508 outputs scaled video signals as pr ogressive

RGBHV, RGBS, RGsB, or component video, from 640 x 480 (VGA) up to 1600 x 1200 (UXGA), to match the optimum or native resolution of virtually any display device, on a 15-pin HD connector.

The output refresh rate is selectable as desired through the on-screen display menu. When used with LCD or DLA displays, Extron recommends the 60 Hz setting. Higher output refresh rates can be used with CRT displays to reduce flicker.

IN1508 Scaling Presentation Switcher • Introduction1-4

Page 14

Audio outputs — The switcher provides an unbalanced line level signal that is

identical to the input signal. This output can drive any line level compatible audio unit, or a local device such as powered speakers.

Video output resolutions — The IN1508 outputs an image scaled up to the

following output resolutions:

• 640 x 480 (VGA) at 50 Hz, 60 Hz, and 75 Hz 800 x 600 (SVGA) at

•

50 Hz, 60 Hz, and 75 Hz

• 852 x 480 at 50 Hz and 60 Hz

• 1024 x 768 (XGA) at 50 Hz, 60 Hz, and 75 Hz

• 1280 x 768 at 60 Hz

• 1280 x 800 at 50 Hz and 60 Hz

• 1280 x 1024 (SXGA) at 50 Hz, 60 Hz, and 75 Hz

• 1024 x 852 at 50 Hz, 60 Hz, and 75 Hz

• 1024 x 1024 at 50 Hz, 60 Hz, and 75 Hz

• 1366 x 768 (wide XGA) at 50 Hz, 60 Hz, and 75 Hz

• 1365 x 1024 (plasma) at 50 Hz, 60 Hz, and 75 Hz

• 1400 x 1050 at 50 Hz and 60 Hz

• 1440 x 900 at 60 Hz and 75 Hz

• 1600 x 1200 (UXGA) at 50 Hz and 60 Hz

• 1680 x 1050 at 60 Hz

• 720 x 480 (HDTV 480p) at 60 Hz

• 720 x 576 (HDTV 576p) at 50 Hz

• 1280 x 720 (HDTV 720p) at 50 Hz and 60 Hz

• 1920 x 1080 (HDTV 1080i ) at 50 Hz and 60 Hz

• 1920 x 1080 (HDTV 1080p) at 60 Hz

Seamless Switching — The IN1508 provides a seamless transition between scaled

low resolution video inputs (inputs 1 through 4 [or inputs 1 through 5 if input 5 is configured as interlaced component video]) and the high resolution inputs (inputs 6 and 7 [or inputs 5 through 7 if input 5 is configured as progressive component video or HDTV]).

Picture-in-picture — One input from either the low resolution (interlaced

component, S-video, and composite video) video inputs or the high resolution (VGA, progressive component, and DVI) video inputs can be selected as the primary picture. A second high resolution or low resolution input can be selected as the secondary picture. The secondary picture is displayed in a user-determined area of the output image. The primary and secondary picture can be swapped with a touch of a button.

Introduction, cont’d

Inverse 3:2 pulldown detection for NTSC video sources and 2:2 film detection for

PAL video sources — This advanced film mode processing feature helps

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 IN1508’s advanced film mode processing recognizes signals that originated from film. The switcher 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 pr ocess is used for PAL film-source video.

Quad-standard decoding — The IN1508’s video decoder provides accurate video

decoding of composite video and S-video in the NTSC, PAL, SECAM, and NTSC 4.43 standards. The advanced 3-line adaptive comb filter that decodes composite video reduces cross-color interference and hanging dots while maintaining maximum image bandwidth and detail.

Picture controls — A wide variety of picture controls are available for fine picture

adjustments:

• Position

• Size

• Brightness and contrast

• Color and tint

• Sharpness Once these adjustments are made, the settings are stored in non-volatile

memory and automatically recalled when the same input source is selected again.

On-screen menus — The switcher puts its menu displays on the output video

stream, for display by the output monitor or projector. The menu system provides easy control of video adjustments. The on-screen menus also make it easy to verify and adjust advanced settings such as output signal resolution, refresh rate, sync format, and the reset to factory defaults function.

Audio follow — When an input is selected on the front panel, the audio input

follows its corresponding video input signal (audio follow). Under RS-232 control, the audio input can be switched to follow either the main window selection or the PIP window selection.

Operational flexibility — Operations such as input and scaling selection and

picture controls can be performed on the front panel or over the RS-232 link. The RS-232 links allow remote control via a PC or control system.

• Front panel control — The switcher’s front panel controller and on-

screen menus support individual input selection, resolution selection, volume control, and complete configuration of the switcher.

• Infrared remote control — The switcher includes an Infrared (IR) remote

control that duplicates all of the front panel functionality and some RS-232 functionality.

• Simple Instruction Set (SIS) commands — The remote control protocol

uses Extron’s SIS commands for easy programming and operation.

Freeze mode — Provides a high quality still image for applications that require

close examination of a specific video frame.

Blank mode — Suppresses the output video image. Blank silences the R, G, and B

video outputs but the switcher still outputs sync. This ensures that the output device does not lose sync lock. Blank mode operates for video and RGB signals that are processed by the scaling circuitry. On-screen displays are not blanked.

Rack mountable — The 1U high switcher can be mounted in any conventional 19"

wide rack using the included rack mounting brackets.

Power — The 100 VAC to 240 VAC, auto-switchable, internal power supply of the

IN1508 provides worldwide power compatibility.

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 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 MLC 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).

Mounting instructions

Rack mount the switcher as follows:

1. Attach the rack mounting brackets to the switcher with the supplied eight #8

machine screws (figure 2-1).

2. Insert the switcher into the rack, aligning the holes in the mounting bracket

with those in the rack.

If the picture-in-picture (PIP) feature is turned on (the PIP On LED, 4, is lit), the input buttons select an input for either the primary (main) window or the secondary (PIP) window. If the PIP feature is turned off, the input buttons select the main output only. See “Input selection operation” on page 3-10 for details.

If the PIP feature is turned on, when an input is selected, the audio associated with that input in the PIP window is muted. The audio does not become unmuted until either:

• It is swapped to the main window.

• A Simple Instruction Set Audio follow source command has been issued

to configure the switcher to make the audio follow the PIP window. See chapter 4, “Serial Communications”.

Input LEDs — The Input 1 through Input 8 LEDs indicate the selected video and audio input(s).

An Input LED that is lit green indicates the primary (main) output. An Input LED that is lit red indicates the secondary output (the input that is

The Output Rate button allows you to select the resolution only; the refresh rate defaults to 60 Hz for each front panel resolution selection. You can select a different refresh rate using the menu system; see “Refresh Rate selection box” later in this chapter for details.

There is a 1-second delay between selecting an output resolution from the front panel (the desired Output Rate LED lights) and the selected change taking effect. This ensures that the screen does not try to change resolutions while you cycle through the available resolutions to the desired setting.

The switcher reports the selected resolution for approximately 3 seconds on the connected output display.

On button — The PIP On button toggles the PIP function on and off.

If you press and hold the PIP On button while you apply power to the switcher, the switcher toggles the output signal type between RGB and progressive component video. If an RGB signal type (RGBHV, RGBS, or RGsB) was selected the last time the switcher was powered, the signal type switches to component. If component video was selected, the signal type switches to RGB.

The audio breakaway switching function, normally available under RS-232 control only, is not available when the PIP function is on.

On LED — When lit, the PIP On LED indicates that the switcher’s PIP function is on.

Swap button — The PIP Swap button toggles the primary and secondary pictures between the main image and the PIP window.

With regard to the PIP function, there are two groups of inputs:

• Low resolution — Inputs 1 through 4 (and input 5 if it is configured as

interlaced component video; see “Input 5 selection” on page 3-18)

• High resolution — Inputs 6 through 8 (and input 5 if it configured as

progressive component video/HDTV; see “Input 5 selection” on page 3-18)

The PIP function toggles between the selected input in each group. The PIP function cannot toggle between two inputs in the same group.

The size of the PIP window is set in the menu system, see “PIP Mode selection box”, on page 3-24, for details. The position of the PIP window is set with the centering adjustment; see “Picture adjustments”, on page 3-25, for details.

If PIP mode is off (the PIP Mode On LED is off), the Swap function continues to work, toggling between the most recently selected low-resolution input and the most recently selected high-resolution input. Unlike when PIP mode is on, however, the input that is replaced in the main window is not displayed in the PIP window.

Operations

The following paragraphs detail the power-up process and then describe the menu system, the picture, and the selection of the front panel security lockout.

Power

Power is applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that cycles all of the front panel LEDs on and off from left to right. An error-free power up self-test sequence leaves the selected input LED and the selected Output Rate LED on. If the picture-inpicture feature was turned on when the switcher was powered down, the PIP On LED and a secondary input LED are also lit.

The selected input, the picture adjustments, and other current settings are saved in non-volatile memory. When power is applied, the latest configuration is retrieved.

Input selection operation

Each of the eight inputs is assigned to one of two groups (see figure 3-9 on the next page):

• Low resolution — Inputs 1 through 4 (and input 5 if it is configured as

interlaced component video; see “Input 5 selection”, on page 3-18)

• High resolution — Inputs 6 through 8 (and input 5 if it configured as

progressive component video/HDTV; see “Input 5 selection”, on page 3-18)

Input selection acts differently, depending on whether PIP mode is on or off:

• PIP mode on — If the PIP mode is on (the PIP On LED is lit), pushing the input button selects a new input for display in either the main window or the PIP window. The window in which the selected input is displayed depends on which group (high resolution or low resolution) the input is in. The selected input replaces the previously selected input from the same group in whichever window that input had been displayed.

• PIP mode off — If the PIP mode is off (the PIP On LED is off), pushing the

input button selects a new input for display in the main window.

In figure 3-9, when you push the Input 3 button, input 3 replaces input 1 in the PIP window.

In figure 3-9, when you push the Input 8 button, input 8 replaces input 6 in the main window.

Picture-in-picture mode operation

The two images displayed when the PIP feature is on (the PIP On LED is lit) must come from different input groups (one high resolution and one low resolution).

• If the primary input (the image displayed in the main window) is a high- resolution input, the secondary input (the image displayed in the PIP window) must be a low-resolution input (figure 3-9).

• If the primary input is a low-resolution input, the secondary input must be a high-resolution input (figure 3-9).

The PIP function toggles between the selected input in each group. In figure 3-9, when you push the Swap button:

• Input 3 replaces input 8 in the main window.

• Input 8 replaces input 3 in the PIP window.

The PIP feature cannot toggle between two inputs in the same group.

Optimizing the Video

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 IN1508.

All sizing adjustments to correct the aspect ratio should be done using the IN1508. 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.

Resolution and refresh rates

Resolution and refresh rate are probably the most crucial variables for optimum image quality. Every display has an optimal or native resolution and an optimal refresh rate. These vary, depending on:

• The type of display technology

• Whether the display has a fixed number of pixels (a native resolution)

• The size of the pixels

• The size of the display or screen

• The distance of the viewer from the screen For best results, set the switcher’s output resolution and refresh rate to match the

capabilities of your display.

IN1508 Scaling Presentation Switcher • Operation3-30

Page 54

The ideal resolution must lie within the compatible range of the display. For example, some 27” to 36” presentation monitors are limited to input signals in the 30 kHz to 50 kHz range. Check the Direct View Display Cross Reference and the Projector Cross Reference on the Extron Web site (www.extron.com) for the most up-to-date compatible ranges of most displays.

CRT displays — selecting the optimum resolution

While CRT displays do not have a native resolution, they do have a “sweet spot“ for input signal resolution. When the switcher is set to output at the sweet spot of the CRT, it results in a detailed image with no visible scan lines. If the switcher is set to output below the sweet spot, the displayed image has small scan lines between the image lines. If the switcher is set to output above the sweet spot, the image’s lines overlap and the image loses detail because there are more lines and pixels than the display can clearly resolve. When experimenting to find the sweet spot, start with the output refresh rate set at 75 Hz and the resolution shown in the table on the next page. Then, with a critical eye, try lower resolutions until you achieve a solid image with optimum image detail.

CRT displays — selecting the optimum refresh rate

CRTs tend to flicker at refresh rates below 70 Hz. To achieve a flicker-free image, try an output refresh rate of 75 Hz.

Note that as the refresh rate increases, the horizontal scan rate also increases, placing greater bandwidth demands on the video distribution system and the display. If the bandwidth is too high, you may see a softer image because the signal exceeds the bandwidth of the distribution system and the display. An extremely high refresh rate can also create a compatibility problem in which the video signal is beyond the scan rate of the display.

Fixed pixel displays — selecting the optimum resolution and refresh rate

Display devices that are based on LCD, DLP, D-ILA, and plasma technology have a specific number of pixels, a native resolution. These displays typically can show higher or lower resolution signals, but can do so only by scaling the image up or down to the native resolution. To avoid additional image scaling by the display (and more processing is inherently bad for image quality), it is important to know your display’s native resolution.

Check the display’s operation manual to determine its native resolution. Set the switcher to match this native resolution. The switcher’s refresh rate should be set to 60 Hz for most LCD, plasma, D-ILA, and DLP projectors.

Higher refresh rates are not recommended for these display technologies. They usually do not improve the image and may cause compatibility problems.

Horizontal Start and Vertical Start status indicator bars

The input start controls adjust where the electronic scaling process takes effect. The input start and active area should be manually adjusted, if necessary, to match the input video signal, framing the active area of the input signal. If the start is set incorrectly, the switcher may add blank borders on the leading edges (top or left side) or it may crop the active area on the trailing edges (bottom or right side).

Figure 3-24 shows an image that is improperly started (as indicated by the dashed lines). If the horizontal start adjustment is set to less than the amount of actual blanking, the IN1508 starts scaling the input before the start of the active image. This early scaling results in a blank border on the left side and cropping on the right side, and looks as if the image is shifted to the right.

Similarly, if the vertical start adjustment is set to less than the amount of actual blanking, the IN1508 starts scaling before the first line of the active image. This early scaling results in a blank border on the top and cropping on the bottom, and looks as if the image is shifted down.

Adjust the H Start status indicator bar to shift the switcher’s starting point horizontally on the screen. Adjust the V Start status indicator bar to shift the starting period vertically on the screen.

If improperly adjusted, the output position variable can result in an image similar to figure 3-24. But, position only moves the image on the monitor. It does not add blank borders or crop any part of the image. However, the apparent effect of blank borders and a cropped image can be caused by the image being improperly positioned on the monitor.

Active Pixels and Active Lines status indicator bars

Figure 3-25 shows an image whose active area is improperly set, as indicated by the dashed lines. If the number of active image pixels that the switcher is set to scale are less than the amount of actual active pixels that are input, the IN1508 only scales the set active area and skips some of the input pixels. This early end to the scaling process results in an output with fewer pixels than it should have, and looks as if the image is stretched horizontally.

Similarly, if the number of active image lines that the IN1508 is set to scale is less than the amount of actual active lines that are input, the IN1508 scales only the set active area and skips some of the input lines. This early end to the scaling process results in an output that has fewer lines than it should have, and looks as if the image is stretched vertically.

Depending on the RGB source, the input sampling rates in the following table may have the same horizontal scan rate and vertical refresh rate. The switcher does not detect pixel space differences (you can have different numbers of pixels in the same horizontal and vertical rates) between input rates. The switcher applies the

IN1508 Scaling Presentation Switcher • Operation3-36

default capture rate to the specified input frequency. It then maintains the aspect ratio based on the difference between the input active area and the output resolution (active area) by inserting blank borders around the images. If, however, you want to fill the entire monitor, you can adjust the input aspect ratio by slightly changing the number of active pixels and active lines to stretch the image. You may also need to adjust the number of total pixels.

Adjust the Active Pixels status indicator bar to increase and decrease the number of active pixels, shifting the starting period horizontally on the screen. Adjust the Active Lines status indicator bar to increase and decrease the number of lines.

Total Pixels

Figure 3-26 — Incorrect total pixels variable

These lines appear as fuzzy vertical bars when an alternating pixels pattern is applied. When the total pixels setting is improperly adjusted the entire image can have a noisy or darkened appearance. Adjusting the phase corrects this.

As an approximate setting, multiply the active pixels setting (see “Active Pixels and Active Lines status indicator bars”, earlier in this chapter) by a factor of 1.3.

If the input pixel clock rate is known, the input total pixels setting can be calculated with this equation:

total pixels = input pixels clock ÷ input horizontal scan rate

Once a preliminary setting is saved, some faint vertical lines may remain. Adjust the total pixels variable as necessary until the lines are completely out of view or as far apart as you can make them. If one line remains, it can be moved out of view using the Phase status bar (see “Phase status indicator bar”, below).

The active pixels and total pixels adjustments are interactive. Setting one of these variables may require adjusting the other.

Phase status indicator bar

The Phase adjustment is available for RGBHV, RGBS, RGsB, and progressive component video inputs only.

The Phase status indicator bar shows, and allows you to adjust, the phase adjustment setting. The phase control adjusts the amount of phase shift applied to the input video signal. Use the front panel or IR remote control

and buttons to

increase or decrease the amount of phase shift through a range of 0 to 31.

Optimizing the Audio

Each individual input audio level can be adjusted within a range of -53 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 output to

an output device such as an audio player. See “Audio connections”, in chapter 2, “Installation”.

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

3. Select an input, listening to the audio with a critical ear.

4. As necessary, adjust each variable for the input (see “Input Gain/Attenuation

status indicator bar”, on page 3-22) for optimum audio quality.

5. Select each input in turn and repeat step 4 for each input.

Troubleshooting

This section gives recommendations on what to do if you have problems operating the switcher, and it provides examples and descriptions for some image problems you may encounter .

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

2. Ensure that the input selected is active.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

receiving power if one of the Input LEDs is lit.

Host-to-Switcher Instructions

The switcher accepts (Simple Instruction Set) SIS™ commands through the RS-232 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-Initiated Messages

When a power-up occurs, the switcher responds by sending the following message to the host:

program might request a new status.

Not used Transmit data Receive data Not used Signal groun Not used Not used Not used Not used

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) E09 — Invalid function number (too large) E10 — Invalid command E13 — Invalid value (out of range) E17 — Invalid command for signal type
