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 roomfunction allows control of such things as lighting or a  
display screen and infrared learningadds 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 Extrons IR library into its memory. The IR library, as well as 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.

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 users 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 learnedIR  
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 users 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 learningor by uploading from Extrons 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  
learningan 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.  
1
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 Relayconnector 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.  
2
Display – (customized for the projector being used)  
________ These buttons only function after being programmed, either by learning,  
or by loading the projectors commands from Extrons IR library. Learning  
is described in the Setup Mode procedures later in this chapter.  
Power After this button has been programmed for the projectors 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 projectors 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 learnan  
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.

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.)

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 mastercontrol 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 devicesremote 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 Extrons 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).

Power Up/Down Delay times  
Many projectors (LCD, DLP, etc.) have a warm-up and cool-down cycle.  
1
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  
2
preset each input to its Cliplevel. 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  
3
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.

Loading Projector Drivers  
A sub-folder under the System 5 folder is used to store the users library  
of projector drivers.  
To view which commands are in a particular driver, without loading it,  
launch the System 5 control software in Emulation Mode (instead of  
selecting a Comm port). You  
will be asked to select from a  
list of drivers. Double-click  
the Drivers folder to open it  
and select a projector. Each  
driver (.5cr) loads the IR  
commands for that projector  
into the System 5 memory.  
During normal operation,  
certain System 5 functions  
will send out associated IR  
signals to the projector.  
Figure 4-8. Example of the Drivers Folder containing Projector drivers, with IR codes.  
Another example for using this folder would be to load the driver for a  
different projector. This could be the users own driver library.

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 Users 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.

Reference Appendix B  
Glossary of terms  
Following is a list of terms taken from Extrons 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 offhas 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 bandof 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 fuzzypicture.  
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  
awayand 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 signals 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 Extrons 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 Users 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 Extrons  
System 5 switcher. Each library file has a set of commands for a specific  
projector, or series of projectors. The files are available at Extrons 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 roomfunction 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 roomfunction 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, Yis an abbreviation for Luma.
