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)
With the proper adapters, the IN1508 can also be used with High Definition

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.

Introduction, cont’d
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.
Extron’s IN9700 extension cable can be used to extend the length of the input
cable. See “IN9700 cable”, below.
•
Only use an input cable specifically designed for DVI signals.
•
Limit or avoid the use of adapters.
•
Use only approved DVI/HDMI connectors.
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.
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:
Resolution
1024 x 768
1280 x 1024
1600 x 1200
Recommended maximum cable length
75 feet
60 feet
35 feet
Features
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 progressive
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.

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 process 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.
1-6
•
Front panel control — The switcher’s front panel controller and onscreen 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.
IN1508 Scaling Presentation Switcher • Introduction
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 multiunit 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 rackmounted 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 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

menu system or SIS commands, no Output Rate LED is lit.
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.
IN1508 Scaling Presentation Switcher • Operation
3-9
Operation, cont’d
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.
°
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.
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.
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 highresolution 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.
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.

Advanced screen
The Input submenu’s Advanced settings are a comprehensive set of
adjustments to optimize the switcher for non-standard video inputs. Most
users do not encounter such signals. For those users who do, the switcher
automatically adjusts these settings. The switcher’s automatic adjustments
are adequate for most inputs.
The Advanced screen provides a submenu of advanced selection options: active
pixels, active lines, phase, horizontal and vertical start, and total pixels. These
advanced settings are rarely needed for standard video and computer video
signals, but provide the user with manual control over scaling parameters that are
automatic. The knowledgeable user may need to adjust these settings to optimize
his or her input signal(s). Possible reasons to adjust these settings include tolerance
issues and nonstandard resolutions and frequencies. The settings are described in
more detail as part of the discussion on optimizing the video. See “Input
submenu’s Advanced selections”, on page 3-33.
To select one of the advanced settings, use the front panel or IR remote control

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.

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.

Input submenu’s Advanced selections
Figure 3-22 shows the selections that are available from the Input > Advanced
screen. The switcher automatically adjusts for different input and output modes.
However, if the input signal has slightly different timing or is non-standard, some
settings may need to be manually adjusted. All settings for each input and output
mode (including non-standard input modes) are stored in non-volatile memory so
that the adjustments do not need to be repeated after the settings are optimized.

The Input submenu’s Advanced settings are a comprehensive set of
adjustments to optimize the switcher for non-standard video inputs. Most
users do not encounter such signals. For those users who do, the switcher
automatically adjusts these settings. The switcher’s automatic adjustments
are adequate for most inputs.
Several Input submenu Advanced selections define the active (image) area of the
input (see figure 3-23 on the next page):
•
Active pixels — The number of pixels per line that are inside the input active
area. The baseline for the active pixels adjustment is the right edge of the
image. This value is often referred to as horizontal resolution.
•
Active lines — The number of lines per frame that are inside the input active
area. The baseline for the active lines adjustment is the bottom edge of the
image. This value is often referred to as vertical resolution.
For interlaced input signals, this variable refers to the total number of lines
per frame after deinterlacing, not the number of lines per field.
•
Horizontal start — The number of pixels per line that are inside the blanking
area to the left of the active area.
•
Vertical start — The number of lines per frame that are inside the blanking
area above the active area.

Total pixels (RGBHV/RGBS/RGsB and progressive/HDTV component

front porch).
The total number of lines per frame, including the blanking above and below
the active area, is determined by the input signal and is not user adjustable.
Use these controls to match the input video signal and to frame the active area.
The active pixels and total pixels adjustments are interactive. Setting one of
these variables may require adjusting the other.

IN1508 Scaling Presentation Switcher • Operation
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

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 • Operation
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

Total Pixels status indicator bar
There are several methods to determine the correct value to use in the total pixels
variable. Usually, the best method is to use the input signal specifications. For
some input sampling rates, the switcher’s setting can result in fine vertical lines
(figure 3-26).
Blanking Area
Active
Area
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
receiving power if one of the Input LEDs is lit.
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 S3 Sales & Technical Support Hotline if necessary.

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:
Copyright 2005, Extron Electronics, IN1508, Version x.xx
Version x.xx is the firmware version number.
The switcher does not expect a response from the host; but, for example, the host
program might request a new status.
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
