What is a System 5cr Switcher?

Throughout this manual, the terms System 5 and System 5cr are both

used to refer to the same product.

The System 5 provides central control for small audio/video installations.

The five inputs accept video formats from composite, S-video and

computer-video sources, together with line-level audio. In addition to

being a video/audio switcher, the System 5 combines the functions of

several devices, including projector control for LCD, DLP and Plasma

Displays. A “room” function allows control of such things as lighting or a

display screen and infrared “learning” adds control for one of many

different projectors.

Controlling the System

The System 5 functions as a switcher as it comes out of the box.

However, to have projector control, it must be programmed. This can be

done by learning projector IR commands or by loading a set of commands

from Extron’s IR library into its memory. The IR library, as well as the

latest control software is available at www.extron.com. Control of the

System 5 and other devices can be done in several ways:

• The front panel

• Windows® control software from a PC

• Through RS-232 port by a PC, a touch screen panel, or any other device

capable of sending and receiving the serial port protocol.

• Optional control pads (SCP 100) can be mounted in a wall, or podium,

and hard-wired to the System 5. Each SCP 100 replicates the front panel

functions and can receive IR signals, and pass them to the System 5.

• The IR 40 remote control has each of the System 5 front panel functions.

Chapter 1 • Introduction and Features

Infrared Learning for System Control

The IR receiver window on the front panel also serves as a learning port

to add IR signals from other sources to the System 5 panel functions.

Then, when a panel function is selected, the learned IR signal is

transmitted into the room through the hard-wired IR emitter, or the

optional IR Broadcaster, to be received by the projector. IR commands for

the projector can be associated with each of the Display buttons (Power,

Mute and Mode) on the front panel as well as with each of the five input

buttons. Thus the System 5 switcher can control the projector. Stored

commands (learned or uploaded) in the System 5 memory are also

effective when using the IR 40, SCP 100 or RS-232 controls.

As an example, IR commands for the projector shown in Figure 1-1 can

be stored in the System 5 memory such that when the VID1 input is

selected, the projector will switch to its composite video mode. Selecting

VID2 input could send a command to tell the projector to switch to S-video

mode.

Standard Features

• 250 MHz bandwidth (-3 dB)

• Audio preamp with 2-channel stereo outputs

• Audio breakaway (switch audio and video separately, with RS-232)

• Audio input levels may be preset individually and then adjusted by the

master volume control.

• Five Inputs - computer video, RGBS, RGBHV, composite video or S-video

• Internal audio amplifier - 12 watt/channel, with adjustable output

• Room control - relay control of lights, window shades, display screen, etc.

• Projector control - display power, mute, mode (learned IR commands)

• Learns IR remote commands - from a library or through the front panel

• Memory stores IR commands that are learned, or uploaded through a PC.

(Procedure in Chapter 4.)

• RS-232 programming, with Simple Instruction Set (SIS)

• Triple-action switching (blank screen while switching between inputs)

• Special mounting brackets allow the System 5 to be mounted on a wall or

under a table, plus standard brackets are included for rack-mounting.

Inputs

_______ The four rear panel inputs described here include a 5-pole, captive screw

connector for 2-channel stereo audio, balanced or unbalanced signals.

• Computer video input is provided on the front panel through a VGA

(female HD 15 pin) connector (PC1). This allows for quick connection of a

laptop computer without having to access the rear panel of the switcher.

• Computer video may also be connected through BNC connectors to the

PC2 and PC3 inputs, through an interface, such as an RGB 406, as

shown in Figure 1-1.

• The VID1 and VID2 inputs can be either composite or S-video signals,

both through BNC connectors.

Outputs

• The System 5 provides video outputs for RGBS, RGBHV, Composite and

S-video formats. One output is active at any one time.

• Audio preamp output for either balanced or unbalanced audio signals is

available through a 5-pole, captive screw connector.

• An internal, 12 watt/channel audio amplifier drives non-powered speakers.

• Stored IR commands output through emitter or broadcaster.

Introduction and Features • Chapter 1

Options and Accessories

The System 5 is more than just a system switcher. Standard and optional

features make it the control center for a small A/V system by adding

control of other things in the room as part of the system design. Two of

these standard features include:

• Room control allows for relay control of lights, window coverings, display

screen, or most anything the system designer wants to use it for.

• An IR transmitter distributes all incoming IR signals, together with the

learned commands in the immediate area.

Optional equipment includes:

• Current sensor (detects when projector power is on)

• Optional remote keypad, SCP 100 (1 or 2)

• IR broadcast device (transmits IR signals over a wide area)

Figure 1-2. System 5 with accessories and options

The System 5 combines switching, room control and projector control,

each of which is controlled at the front panel, by hard-wired control pad

(SCP 100) and by IR remote control (IR 40). The switcher can be used to

control video and audio input settings, display functions such as power,

mute and video modes, and room controls, such as lowering or raising a

display screen or powering lights on or off.

Installation in a Rack, on a Wall or Under a Table

The System 5cr comes with two sets of mounting brackets. One set is for

mounting under a table or on a wall and the second set is for rack

mounting. Either set is attached to the System 5 by four #8 screws.

When mounted under a table on a wall, the bracket will extend

approximately 1/4 inch above the top surface of the System 5 enclosure,

as shown in Figure 2-1. This is designed to have an air space between

the System 5 enclosure and the surface it is mounted on.

A second set of brackets (top example) has slotted holes that face

forward to accommodate rack-mounting hardware. When attached to the

System 5 enclosure, the forward-facing holes will align with the holes in a

standard rack.

_______ Although all three outputs may be connected at the same time, only one

can be active at one time, as determined by the input format. In a typical

installation, an LCD projector may have inputs for all three formats. In

such cases, each of the three System 5 outputs would be connected to

the same projector.

R, G, B, H/HV, V BNC connectors, for RGBS or RGBHV output. The

green LED indicates when the selected input is RGB format (PC1, PC2 or

PC3) and this output is active.

Y and C BNCs for S-video output. A BNC-Din adapter may be required.

The green LED indicates when the selected input is S-video format (VID1

or VID2, if set up for S-video format) and this output is active.

Figure 2-5. The right side of the rear panel has three video outputs, plus audio and options.

VID is for Composite video output. The green LED indicates when the

selected input is composite video format (VID1 or VID2, if set up for VID

format) and this output is active.

Audio PreAmp Out – This output has the audio signal from the selected

input and should be connected to a stereo audio amplifier. The signal is

the same as item 18, at a low level. Both audio outputs are affected by the

volume control. See detailed section on audio connectors.

_______ Audio breakaway is available if programmed through RS-232. If so, the

selected audio input may be different from the selected video input.

Aux1 and Aux2 each can accommodate a connection to an optional

external control panel (SCP 100). See the SCP 100 User’s manual and

“Connecting Accessories” later in this chapter. See specifications

_______ The AUX 1 & 2 ports of the System 5cr provide a total of 500mA. This is

split between the two ports offering 250mA for each port.

Relay Contacts (one normally open pair and one normally closed pair) are

controlled by the “Room” button on the front panel to control external

functions, such as lighting, display screen up/down, etc. See “Connecting

Accessories” later in this chapter.

Comm – This is the connection for the IR emitter or the optional remote

IR Broadcaster. Both of these devices transmit only learned IR signals

from the System 5 to the projector, IR 40 commands are not included.

The optional Broadcaster covers a much wider area than the emitter.

_______ A 12VDC, 500mA output is provided on the Comm. (IR Emitter) port.

connectors in the rear panel. Figure 2-7 shows four of the captive screw

connectors for the Room Relay, IR Emitter or IR Broadcaster and the two

SCP 100 remote panels. There is also one round connector for an

optional Display power Sensor. Each accessory product has its own

user’s manual and is also summarized in Appendix B of this manual.

Making Connections • Chapter 2

3.5 mm, 5-pole captive screw connectors are used for the audio inputs

and one output, as well as for accessories. These include:

• Aux1 & Aux2 – SCP 100 remote panels (2 optional)

• Relay – Room/relay custom control (standard feature)

• Comm – projector control through the standard IR Emitter or the optional

IR Broadcaster.

One three-contact stereo phono-type of connector is provided for the

optional Display Power Sensor. This device detects when the projector

power is on.

All connectors are provided. Cables are the responsibility of the installer.

The two standard accessories described in this section are the Infrared

Emitter and the Room/Relay custom control. Figures 2-7, 8 and 9 show

accessory connections. Optional devices (SCP 100, the IR Broadcaster

and the Power Sensor) are also covered in their separate user’s guides

and are summarized in Appendix B of this manual.

Comm Connector and Infrared Emitter

This connector is for projector control,

and can be used in different ways:

1a. Connect the IR Emitter (included) to

transmit all of the “learned” IR

commands to the projector. The IR

Emitter includes a black cable with two

wires, one has a white stripe. Insert the

wire with the white stripe into the

carrier/signal pin (C) and the solid black

wire to either ground contact (B or D).

1b. If a wired remote can be plugged into

the projector, that cable will use pins A

(signal) and B, as shown in Figure 2-7.

Figure 2-8. The IR Emitter can be used from the Comm connector or through an IR Broadcaster.

2. To install and use the optional IR Broadcaster, and to use emitter with the

IR Broadcaster, see user’s guide 68-392-02. For some projectors, the IR

Emitter must be used with the broadcaster.

The standard IR Emitter transmits infrared signals over a short, narrow

range, while the IR Broadcaster covers a wider, longer area. Both of these

devices transmit only the IR commands that have been stored in the

System 5, either through “learning” or by uploading from Extron’s IR

library. If the broadcaster is installed, the emitter may not be needed.

Room/Relay Connector

The Room Relay contacts are shown in Figure 2-9. One relay has two

sets of contacts – one set is normally closed and the other is normally

open. When the Room function is active, the normally closed contacts are

open and the normally open contacts are closed.

The contacts can be programmed to operate either of

two ways: latched (press-on, press-off) and momentary

or timed (press-on, time-out-off, default = 1/8 second).

Timing can only be set through Windows® control

software, through a PC.

Operating the System 5cr • Chapter 3

Using the System 5cr

________ In addition to the basic function of each of the panel buttons described

here, there are also setup procedures that use many of the same buttons

and controls. Each of the Input and Display buttons is capable of

“learning” an IR command. The Display Power button must learn both

power on and power off for the projector. The setup procedures are

described later in this section.

Front Panel Controls and Indicators

On power up, all of the LEDs light and then go off, except for the Power

LED and the LED for the input last selected. On the rear panel, the LED

for the selected input format will be lit.

Power and Room

Power LED – Indicates when the System 5 has power.

Room Button and LED – These work with the relay contact connections

provided on the rear panel of the System 5. The button can activate/

deactivate a room condition, such as turn lights on/off and raise/lower a

viewing screen. The LED indicates that the condition is active. Exactly

how the feature is used depends upon the user-defined application and

what is connected to the “Relay” connector on the rear panel.

Figure 3-1a. Front Panel Buttons and Indicators

The Room button can be set to operate in either of two ways: latching

(press on, press off) or momentary (press on, off after time-out). The time-

out value can only be set through the Windows® Control Program.

_______ For example, pressing the Room button once could lower a screen and

turn room lights off and the LED will remain lit. Press the button again to

turn the room lights on, raise the viewing screen and the LED goes out.

Display – (customized for the projector being used)

________ These buttons only function after being programmed, either by “learning”,

or by loading the projector’s commands from Extron’s IR library. Learning

is described in the Setup Mode procedures later in this chapter.

Power – After this button has been programmed for the projector’s IR

remote commands, it will toggle power to the display device on or off.

Because there is a warm up delay and a cool down delay for many

projectors, the Display Power LED will blink fast during projector

power up and will blink slowly during projector power down. The

blinking time is generated within the System 5; it does not come from

the projector. Its duration can be programmed through RS-232.

Mute – After this button has been programmed for the projector’s video

mute signal, it will function as the Display Mute on/off switch.

Mode – Effective on display devices that do not automatically detect the

type of video signal, this button can be programmed to change the

mode of the display device between computer-video, composite video

and S-video. This can duplicate the single-button (step) mode function

found on some projector remote controls.

Chapter 3 • Operating the System 5cr

________ As stated earlier, each input button can be programmed to “learn” an

associated IR command. For example, selecting the PC1 input could also

send a signal to the projector to switch to its computer input mode, and

selecting VID1 could cause the projector to switch to S-video mode, etc.

PC Input Selection Buttons and Indicators:

• PC1 – Input select button for computer video and audio. This selects the

input from the VGA and Audio connectors on the System 5 front panel.

• PC2 – Input select button for an RGBS or RGBHV source (and audio)

from the PC2 section of the rear panel. This could be from a computer,

through a computer-video interface.

• PC3 – Same as PC2 but input is from the PC3 section of the rear panel.

Composite or S-video inputs (VCR, DVD, etc.):

VID1 – 1st input select button for Composite Video or S-video with audio.

VID2 – 2nd input select button for Composite Video or S-video with audio.

Audio Gain (Volume) Control knob for amplified output.

Max LED (red) – lights when the audio output level control has reached its

maximum point. This does not indicate the audio level.

Clip LED – lights when the output level is beginning to overdrive (peak).

This indicator is used to set the audio attenuation for the inputs.

Min LED – lights when the output level control has reached its minimum

point. This does not indicate the audio level.

_______ When all audio inputs are at the same level coming into the System 5cr,

the Volume knob functions as the master volume control for both audio

outputs. (See Setup Mode procedures later in this chapter.)

PC1 Input connectors – Audio and Computer VGA connectors selected

by the PC1 button. Connect a VGA cable to the 15-pin HD connector.

Plug the computer’s audio output to the audio jack.

_______ Each of the controls described above are duplicated on the IR 40 remote

control, on the optional SCP 100 panels, and on the Windows® control

software. The operation is the same, including associated IR commands.

Operating the System 5cr • Chapter 3

Configuration Setup from the Front Panel

For the System 5 switcher to control other equipment in the A/V system, it

must be configured from the front panel, or through an RS-232 device.

This cannot be done from an IR 40 or SCP 100. See Chapter 4 for

Windows® Control program and Appendix A for RS-232 instructions.

Infrared Programs and Libraries

Extron provides a library of drivers for most projectors. To download a

driver from the library, see the procedures located in Chapter 4. A typical

projector driver assigns projector IR commands to the System 5 panel

functions such that the Display Power, Mute and Mode functions can

control the projector. Also, once programmed, selecting PC1, PC2 or PC3

inputs can set the projector to RGB format, while VID1 and VID2 can set

the projector to either S-video or Composite Video. Selection can be from

the front panel or by remote. To configure the System 5 from the front

panel, use the following procedures.

Enter Setup (Config) Mode

Each of the procedures in this section is done from Setup (or Config)

Mode. Once in Setup Mode (Config LED = On),

you may go from one procedure to another

without returning to Normal Mode.

To enter Setup Mode, press and hold all 3

Display buttons (Power/Mute/Mode) for 2

seconds. The Config LED lights. Go to the

appropriate procedure. Pressing the same 3

buttons will also exit Setup (Config) mode.

Figure 3-2a. Enter Setup Mode from the Front Panel.

Clear Configuration(s)

To Clear existing configuration(s) to the factory default, from Setup Mode,

double-click the Room button. The Room LED blinks for 8 seconds.

During that time, do one of the following:

Clear One – press the desired button to clear only its IR configuration.

Clear ALL – press all 3 Display buttons (Power/Mute/Mode) at the same

time for 2 seconds to reset all IR and other settings to factory defaults.

Preset Audio Input Attenuation Levels

For the Audio Volume control to act as a “master” control for all inputs, all

audio inputs must be set for same level. With audio input signals

connected and active, enter Setup Mode and do the following:

1a. Press the input button twice (double-click) for the audio input to be

adjusted. The input LED blinks.

2a. Slowly adjust the Volume knob up (cw) until Clip LED is On or blinking

frequently with changes in sound level.

3a. Adjust Volume down (ccw) just until Clip LED is Off or blinks occasionally

as the level peaks.

4a. Press the input button again to save the setting.

5a. Repeat steps 1a through 4a for each audio input.

6a. While still in Config mode, you may go directly to another procedure, wait

for 20 second time-out or press and hold all 3 Display buttons for 2

seconds to force a return to normal operation.

Figure 3-2b. Set the audio input attenuation to the same levels.

Select format for VID1 and/or VID2.

To set these two inputs for either Composite or S-video, in Config Mode,

do the following:

1b. Press and hold the Room button until finished with this operation.

After 2 seconds, one of the VID1 LEDs lights.

2b. Press VID1 to toggle between VID (Video) and Y/C (S-video) formats.

3b. Repeat step 2b to select the format to set the format for the VID2 input.

4b. Release the Room button to go back to Config mode.

5b. While in Config mode, you may go directly to another procedure, wait for

20 second time-out or press all 3 Display buttons for 2 seconds to exit.

Figure 3-2c. Select input format for VID1 and VID2.

Learn Infrared Signals from other devices’ remote controls

This procedure is only necessary if the IR driver is

not available for the system projector, or is not

complete. A flow chart of the learning procedure is

shown in Figure 3-2d and a table of LED codes is

shown in Figure 3-2e. In Setup Mode, do this:

1c. Press the panel button to be programmed and hold

it for 2 seconds. The Config LED blinks.

2c. Point the IR remote source at the System 5 IR

Remote window and press the button briefly, but

firmly, for the signal to be “learned”.

Figure 3-2d. Learn infrared signals from other remotes.

_______ It may be necessary to hold remote as near as 1/2 inch and point it

directly into the IR window. It may also help to block out ambient light,

such as from fluorescent sources.

The Config LED remains On while TX & Retry LEDs flash to indicate

that the operation is complete. (If Retry blinks once and TX - Off, repeat

this step). See LED codes in Figure 3-2e below.

_______ The Display Power button learns 2 signals. After learning the 1st signal

(e.g. Power On), the Config and Retry LEDs blink to indicate that it is

ready to learn the second signal (Power Off). Double-click the Power

button and repeat step 2c to learn the second signal.

3c. Repeat steps 1c and 2c to program the next button.

4c. While in Config mode, you may go directly to another procedure, wait for

20 second time-out or hold all 3 Display buttons for 2 seconds to exit.

________ Once the display device (projector) has been programmed to operate

from the System 5cr, those same control functions should not be done

from the projector because the System 5 has no way of knowing what was

done at the projector. That is, if the projector was turned on at the

System 5 and turned off from the projector panel, the System 5 thinks the

projector is still on.

Remote Operation

________ See inset (top, right)

to install batteries.

The System 5

includes one infrared

remote control (IR 40)

and can have one or

two optional remote

control panels (SCP

100). Each of these

devices replicate the

front panel controls

for normal operation.

Learning and other

things done in Setup

Mode cannot be done

from these remote devices.

The IR 40, shown in Figure

3-3, uses + and - buttons for

Volume up and down.

The Function and Enter buttons

on the IR 40 do not affect the

System 5 operation.

Figure 3-3. The IR 40 has the same controls as the front panel.

The optional SCP 100 panels can be

mounted in a wall or piece of furniture,

such as a desk or podium. In addition to

duplicating front panel controls, they also

receive IR 40 signals and pass them to

the System 5. Infrared signals from other

devices are blocked at the System 5, and

do not pass on to the IR emitter or

broadcaster.

Figure 3-4. The optional SCP 100 also passes IR 40 signals to the System 5.

Other ways to control the System 5 include using the RS-232 serial port.

This can be through a host, such as a touch-screen panel or a PC, using

the Windows® operating system. RS-232 programming is covered in

Appendix A of this manual.

Certain operations can be done only through Extron’s System 5cr Control

Program, these include:

• Room Relay Mode (Latched/Momentary)

• (projector) Power Up/Down Delay times

• Auto Set Attenuators (set all audio input to the same level).

The use of Extron’s Windows® Control Program is covered in Chapter 4

The “Normal” operation panel is like the one shown in the Help screen in

Figure 4-3. Some of the panel controls are explained on the following

page. Some functions can only be done through this panel.

The System 5 comes with factory defaults and no “learned” IR commands

stored in memory. Learning IR codes from the projector’s remote control

is covered on page 3-4. Panel settings made using this software, together

with stored IR codes (learned or loaded) may be saved as a system file

(page 4-4) and restored at another time.

Windows® Control Software • Chapter 4

Power Up/Down Delay times

Many projectors (LCD, DLP, etc.) have a warm-up and cool-down cycle.

During these times, the projector may not accept commands. The times

for each projector may be different. The System 5 has timers that can be

adjusted to represent these delay times, thereby warning the operator not

to send commands while the Power LED is blinking. Slide the scroll bar

for Pwr-Up Delay and/or for Pwr-Dn Delay to match the times required by

the projector being used with the System 5. These settings determine how

long the Display Power LED on the front panel blinks during power up and

power down of the projector. These settings do not control the projector

times; they simulate it. Settings are from 10 to 300 seconds (5 minutes),

in 10 second steps. The factory default is 30 seconds.

Auto Set Attenuators (set all audio input to the same level)

With the audio input sources active, click this button to automatically

preset each input to its “Clip” level. Once this is done, the Volume control

(from the front panel, a host or remote SCP 100) will operate as the

master Volume control.

Room Relay Mode (Latched/Momentary)

This allows the selection of two modes for customizing the operation of

the Room control function. Depending upon what the designer wants the

function to control, it can operate in either of two ways.

• Latched – click this button to make the Room button operate as follows:

press to activate the relay and press again to deactivate (unlatch) it.

• Momentary – click this button to make the Room button operate as

follows: press the Room button to activate; deactivation takes place after

a prescribed time, as set by sliding the scroll button up or down. The time

value is displayed from 1/8 to 2 seconds, in 1/8 second steps.

________ The Windows® Control Program is the only way to adjust the time

duration for this mode.

Figure 4-5. Example of the System 5 operational screen.

In the System 5 Control program, select one of the Room Relay Mode

buttons. If Momentary is selected, move the scroll bar and observe the

time duration displayed in the box below the scroll bar. Settings are from

1/8 to 2 seconds, in 1/8 second steps. Factory default is for Momentary

Mode at 1/8 second. Thus, when the Room button is pressed, the relay is

active for 0.125 seconds and then becomes inactive.

System 5cr Options

Figure B-1 illustrates the options and accessories that operate with the

System 5. The standard accessories installation is covered in Chapter 2

and each option has its own User’s Guide. This section summarizes the

three options: SCP 100, IR Broadcaster and Display Power Sensor.

Figure B-1. The options connectors are located to the right side of the rear panel.

All of the necessary connectors are provided with the products, but cables

must be custom made according to the requirements of the installation.

The Display Power Sensor is also shown in Figure B-1. Its cable is one-

to-one, ring = signal, tip = +12 volts and sleeve = ground. The optional IR

Broadcaster uses the same contact assignments.

________ When connecting a Power Sensor or IR Broadcaster, remember that the

System 5 supplies the +12 volts to the tip of the connector. Therefore the

cable should be plugged into the option device before connecting it to the

System 5 rear panel, where the voltage source is.

________ Do not plug any other devices into the rear panel connectors, except

those described here.

For detailed instructions, see appropriate document.

Notes: The IR Broadcaster requires a 3-wire cable to connect:

+12 V from tip to contact E, signal from Ring to contact C and Ground from Sleeve to

either contact B or D.

If using the IR Broadcaster that has an emitter connector (60-272-02), use pin A from the

System 5 for signal without carrier. The carrier will then be generated by the IR

Broadcaster, for a specific frequency range.

Ground from Sleeve to Sleeve.

Note: The sensor has a 2-wire cable already

attached to the Power Sensor unit.

Glossary of terms

Following is a list of terms taken from Extron’s Glossary.

AC Reset –

Refers to status that changes when power is removed from a device. Many

electronic devices have live power inside, even after “Power off” has been

initiated from a panel or remote control device. This is not the same as “AC

Reset”, when power is removed at the AC cord.

Attenuation –

Audio follow –

The decrease in magnitude (of a signal).

A term used when audio is tied to other signals, such as video, and they are

switched together. (The opposite of Breakaway)

Balanced Audio –

Bandwidth –

A method that uses three conductors for one audio signal. They are plus (+),

minus (-) and ground. The ground conductor is strictly for shielding, and does not

carry any signal. Also differential audio.

A frequency range, or “band” of frequencies, within which a device operates. In

audio and video, it is the band of frequencies that can pass through a device

without significant loss or distortion. The higher the bandwidth, the sharper the

picture; low bandwidth can cause a “fuzzy” picture.

Breakaway –

The ability to separate signals for the purpose of switching them independently.

For example: an audio and video signal from the same source may be “broken

away” and switched to different destinations. The opposite of the term “follow”.

Buffer –

Generally referred to as a unity gain amplifier used to isolate the signal source

from the load. This is for both digital and analog signals.

Chroma –

The color information (hue and saturation), independent of luma intensity. Black,

gray, and white objects do not have chroma characteristics.

Chroma Signal –

Clip, Clipping –

Part of a television signal containing the color information. Abbreviated as “C”.

The level at which a signal excursion begins to exceed limits of the circuit and

flattens out, distorting the signal. When setting audio attenuation, the clip level

can be defined as a level short of the distortion point, thus allowing “headroom”

and maintaining the signal’s fidelity.

Composite Sync –

A signal consisting of horizontal sync pulses, vertical sync pulses, and equalizing

pulses only, with no signal reference level. Also referred to as RGBS.

Composite Video –

Differential Audio –

DLP –

A combined signal which includes luma black and white, chroma (color), blanking

See Balanced Audio.

Digital Light Processing – Also DMD (Digital Micro-mirror Device). Uses an array

of mirrors that move independently, reflecting light to compose the picture.

Gain –

A term used to denote an increase in signal power or voltage produced by an

amplifier in transmitting a signal from one point to another. The amount of gain is

usually expressed in decibels above a reference level. Opposite of Attenuation.

Headroom –

The margin between a nominal operating signal level and peak clipping

(distortion) level. See Clipping.

High Impedance

(Hi Z/High Z) – This is typically 10k ohms or greater. In video, when the signal is

not terminated locally, there may be a switch for Hi Z or some termination value

(75 ohms). Hi Z is used if termination is provided by another device.

IR Learning –

The ability of a device to receive and store infrared commands for other devices,

such as the projector. With Extron’s System 5, each command is assigned to a

system operation (such as selecting an input). When an operation is executed,

B-3

Extron • System 5cr Switcher • User’s Manual

Download from Www.Somanuals.com. All Manuals Search And Download.

Appendix B • Reference

the associated (learned) command is then transmitted through an IR emitter or

broadcaster to the projector, where it is executed. For example, if input #3 is

S-video, selecting that input also sends a signal to the projector to switch to

S-video mode. See IR library.

IR Library –

A library of infrared commands for video projectors that can be used with Extron’s

System 5 switcher. Each library file has a set of commands for a specific

projector, or series of projectors. The files are available at Extron’s web site and

for uploading to the System 5 memory. Once installed, appropriate IR commands

are assigned to operational functions, which are transmitted when that function is

activated, allowing the System to control the projector. See IR learning.

Latching –

LCD –

For a device that has two states, such as a relay or a switch, latching means that

once put into the active state, the condition remains until it is taken out of that

state by some action. Often the same action latches and unlatches alternately. In

the System 5, the Room relay can operate in two modes: latching or momentary.

Liquid crystal display – A panel that utilizes two transparent sheets of polarizing

material with a liquid containing rod-shaped crystals between. When a current is

applied to specific pixel-like areas, those crystals align to create dark images. The

dark areas are combined with light areas to create text and images on the panel.

LCD panels do not emit light but are often backlit or side-lit for better viewing.

LCD panel –

A device used to project video images through a liquid crystal display and an

overhead projector onto a large screen. The panel is placed over the stage of an

overhead projector, projecting the computer display onto a screen.

LCD projector –

Utilizing the LCD technique, these projectors separate the red, green and blue

information to three different LCD panels. Since LCD panels do not produce

color, the appropriate colored light is then passed through each panel and

combined to exit through the projector lens and onto a viewing screen.

Level (audio) –

A term used with signal voltage, power, strength or volume. Audio level can be

expressed as attenuation (less than the original) or gain (more than original).

Library –

Luma –

See IR Library.

This is the signal that represents brightness in a video picture. Luma is any value

between black and white. In mathematical equations, luma is abbreviated as “Y”.

Relay –

RGB Delay –

Room (control) –

RS-232 –

In the System 5, a “room” function controlled from the front panel or by a remote

device, which provides normally open and normally closed contacts to a

connector, allowing the user to control other electrical devices.

When switching between video inputs, for a brief time, the signal out of the

switcher may be unstable while locking in on the new sync. RGB delay turns the

video on after the sync has stabilized, providing seamless switching.

The “room” function controlled from the System 5 front panel or by a remote

device provides relay contacts to a connector, allowing the user to control other

devices electrically. Examples include window blinds, lighting, projection screen.

A method of communicating between two devices using two lines: Tx to transmit

and Rx to receive. Tx on one end becomes Rx on the other. This standard does

not specify balanced control lines.

Serial Port –

A connection that allows communication with other devices over a single pair of

wires. The serial port is most often used with RS-232 protocol.

S-video –

Y –

The composite video signal is separated into the Luma (Y) and the Chroma (C).

In video, “Y” is an abbreviation for Luma.
