IN1508 • Introduction 1

About the Switcher

The Extron IN1508 is an eight-input video and stereo audio switcher that incorporates a

video scaler. 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 with

EDID emulation (see “DVI Video” on page 3 for an introduction to the DVI video

format)

NOTE: With the proper adapters, the IN1508 can also be used with non-HDCP

• Eight unbalanced stereo or mono audio inputs (ve 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.

High Denition Multimedia Interface (HDMI®) signals.

The IN1508 seamlessly switches between the VGA and low-resolution video inputs. Seamless

switching allows switching between sources without a loss of sync.

The scaler in the switcher 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 inch 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, power supply that

provides worldwide power compatibility.

IN1508 • Introduction 2

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 on input 8 to analog RGB video. EDID emulation defaults to 1024 x 768 at 60 Hz, but this value can be changed under Simple Instruction Set (SIS™) control. 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 vulnerable 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 input to switcher when using standard DVI

cables.

NOTE: Extron IN9700 extension cable can be used to extend the length of the input

cable (see “IN9700 cable”, below).

• Only use an input cable specically designed for DVI signals.

• Limit or avoid the use of adapters.

• Use only approved DVI/HDMI connectors.

NOTE: Use only cables specically intended for DVI or HDMI interfaces. Use of

non-DVI or non-HDMI cables or modied cables can cause the switcher to be unable to receive the DVI input.

IN9700 cable

Extron 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 Recommended maximum cable length

1024 x 768 75 feet 1280 x 1024 60 feet 1600 x 1200 35 feet

IN1508 • Introduction 3

Features

Inputs —

Video inputs — The switcher switches among:

• Two fully-congurable 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.

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 a wide variety of output resolutions and rates (see page 28 for a detailed list).

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 congured as interlaced component video]) and the high resolution inputs (inputs 6 and 7 [or inputs 5 through 7 if input 5 is congured as progressive component video or HDTV]).

Picture-in-picture — Two inputs can be displayed on the IN1508 output simultaneously by using the picture-in-picture (PIP) feature. The two images displayed must come from different input groups (one high resolution and one low resolution). The primary and secondary PIP inputs can be instantly swapped at the touch of a button.

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 lm. When lm 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 advanced ﬁlm mode of the IN1508 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.

IN1508 • Introduction 4

Quad-standard decoding — The video decoder of the IN1508 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 front panel controller on the switcher 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.

• SIS commands — The remote control protocol uses the Extron SIS commands for easy

programming and operation.

Auto Image™ (inputs 6 and 7 only) — The auto imaging feature automatically sizes and centers the selected input to ﬁll the screen.

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-inch

wide rack using the included rack mounting brackets.

Power — The 100 VAC to 240 VAC, internal power supply of the IN1508 provides

worldwide power compatibility.

Input Controls

Input buttons — The Input 1 through Input 8 buttons (see ﬁgure 9) select the

associated video input to scale and output. The switch can be a cut or a fade, depending on the switch mode (see “Fade Switch selection box” on page 32). With front panel input selection, audio always follows (switches with) the front panel video selection.

NOTE: Video breakaway switching and audio breakaway switching are available

under SIS control (see “Programming Guide”. Audio breakaway switching is not available when the PIP function is on).

Figure 9. Input Selection Buttons and LEDs

NOTES: • If the picture-in-picture (PIP) feature is turned on (the PIP On LED, d,

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 18).

• 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.

IN1508 • Operation 10

Auto-Image™ (inputs 6 and 7 only) — Input 6 and input 7 support the Auto-Image function, which automatically sizes and centers the selected input to ﬁll the screen. Press and hold the selected input button for approximately 4 seconds to execute Auto-Image.

NOTE: Auto-Image sets the picture control window center, size, horizontal and

vertical start, and horizontal and vertical active pixels controls. It does not affect the total pixels, phase, or aspect ratio controls.

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. If the audio is broken away (switched separately from the video), the Input LED for the selected video light green and the Input LED for the selected audio blinks green.

NOTE: The audio breakaway indication is not available when the switcher is in PIP

mode (the PIP On LED, d, is lit).

An Input LED that is lit red indicates the secondary output (the input that is displayed

in the PIP window).

NOTE: No input LED lights red if the PIP feature is turned off.

Output Rate Selection

Output Rate button — The Output Rate button (ﬁgure 10) cycles through the

available output screen resolutions. Use this button to select the native resolution of the connected video display device. The switcher defaults to a refresh rate of 60 Hz with

each resolution selection using the Output Rate button.

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-in-picture 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 conguration is retrieved.

IN1508 • Operation 17

Input Selection Operation

Each of the inputs is assigned to one of two groups (see ﬁgure 16 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 25).

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

component video/HDTV (see “Input 5 selection” on page 25).

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

• PIP mode on — If PIP mode is on (the PIP On LED is lit), pressing 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 16, when you press the Input 3 button, input 3 replaces input 1 in the PIP

window.

• In ﬁgure 16, when you press 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), pressing 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 high-resolution

input, the secondary input (the image displayed in the PIP window) must be a low-resolution input (see ﬁgure 16).

• If the primary input is a low-resolution input, the secondary input must be a

high-resolution input (see ﬁgure 16).

The PIP function toggles between the selected input in each group. In ﬁgure 16, when you press 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.

NOTES: • 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.

• Figure 15 shows the window size options available using the menu system

NOTE: The Advanced settings available from the Input submenu are a comprehensive

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

Optimizing the Video

Setting up a DVD Source

Resolution and Refresh Rates

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 scaling and compression functions of the DVD player

defeat 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 setup or action menu of the DVD player while the disc is stopped.

2. Select the 16:9 aspect ratio.

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 xed 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

IN1508 • Operation 38

Selecting the Optimum Resolution and Refresh Rate for Fixed Pixel Displays

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 the native resolution of your display.

Check the operation manual for the display to determine its native resolution. Set the switcher to match this native resolution. The refresh rate of the switcher should be set to

60 Hz for most LCD, plasma, D-ILA, and DLP projectors.

NOTE: Higher refresh rates are not recommended for these display technologies. They

usually do not improve the image and may cause compatibility problems.

For best results:

1. Set the output resolution and refresh rate of the switcher to match the native resolution

of your display.

2. Output the White Field test pattern and then execute the auto image function of your

display (this function may be called auto adjust or auto setup).

3. Output the Alternating Pixels test pattern and use the clocking or total pixels adjustment

of your display to eliminate any vertical bars in the display.

4. While still outputting the Alternating Pixels test pattern, use the ne sync or phase

adjustment of your display to eliminate any remaining noise.

5. Output the Crop test pattern and use the centering of shift controls of your display to

center the image so that all four sides of the crop lines are visible.

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.

• 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 only) — The

total number of pixels per line, including the blanking on both sides of the input active area and sync (horizontal active, front porch, horizontal sync, and back porch).

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 32 shows an image that has incorrect horizontal and vertical start settings (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 right.

Figure 32. Incorrect horizontal and vertical start settings

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 starting point of the image 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

gure 32. 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.

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.

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 total pixel differences (you can have different numbers of pixels in the same horizontal and vertical rates) between input rates. The switcher applies the default values for the detected input frequency.

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

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 specications. For some input sampling

rates, the setting of the switcher can result in ﬁne vertical lines (ﬁgure 34).

NOTE: If input signal speciﬁcations are not available, see the table on the previous page.

Total Pixels

Figure 34. Incorrect Total Pixels Variable

These lines appear as fuzzy vertical bars when an alternating pixels pattern is applied. When

the total pixels setting is correctly adjusted the entire image can have a noisy or darkened appearance. Adjusting the phase corrects this.

If you know the input pixel clock rate, calculate the input total pixels setting as follows:

total pixels = input pixels clock ÷ input horizontal scan rate

Once a preliminary setting is applied, 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 possible.

NOTE: The active pixels and total pixels adjustments are interactive. Setting one of these

variables may require adjusting the other.

NOTE: The Phase adjustment is available for RGBHV, RGBS, RGsB, and progressive

Optimizing the Audio

Troubleshooting

Each individual input audio level can be adjusted within a range of -65 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” on page 7).

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 30) for optimum audio quality.

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

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 acting 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.”

General Checks

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

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 (see the last page of

if one of the Input LEDs is lit.

Host-to-Switcher Instructions

The switcher accepts SIS commands through the RS-232 port. SIS commands consist of one or more characters per ﬁeld. No special characters are required to begin or end a command

character sequence. When a command is valid, the unit executes the command and sends

a response to the host device. All responses from the unit to the host end 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

ASCII to Hex Conversion Table

•

Space

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

host:

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

UL guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the

switcher into a rack (ﬁgure 36).

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 IN1508 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 36).

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

in the rack.
