Introduction and Features • Chapter 1 cr Switcher? What is a System 5cr 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.
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.
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.

Making Connections • Chapter 2 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.
Chapter 2 • Making Connections Figure 2-2a. The left side of the rear panel has four of the five inputs. 6 PC1 input is on the Front Panel and accepts laptop video through a VGA connector as well as 2-channel audio through a 3.5 mm jack, as shown in Figure 2-2. With a buffered output, VGA signals can be driven up to 50 feet without additional amplification. Figure 2-3. PC1 Input is on the Front Panel.
Making Connections • Chapter 2 _______ 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. 11 12 R, G, B, H/HV, V BNC connectors, for RGBS or RGBHV output.
Chapter 2 • Making Connections Audio Preamp Out Connection Connect balanced or unbalanced, 2-channel audio to the Preamp Out connector marked L (Left) and R (Right), using a captive screw connector. Possible connections are shown in Figure 2-6. Connectors are included with each System 5, however, cables are the responsibility of the installer. Use the same procedure as for the audio input captive screw connectors. Figure 2-6. Audio Preamp Output can be connected three different ways.
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.
System 5cr Switcher User’s Manual 3 Chapter Three cr Using the System 5cr Front Panel Controls & Indicators Configuration: Audio Preset, VID Formats & IR Learning
Operating the System 5cr • Chapter 3 cr 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.
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. 3 • • • 4 5 _______ PC Input Selection Buttons and Indicators: PC1 – Input select button for computer video and audio.
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.
Chapter 3 • Operating the System 5cr 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.
Operating the System 5cr • Chapter 3 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.

Use the cursor (pointing finger) to display a description of that section. The operational version of this screen is used to set/view various system parameters and to view the IR command (if any have been learned or loaded) associated with the various front panel buttons.
Windows® Control Software • Chapter 4 Power Up/Down Delay times 1 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.
Chapter 4 • Windows® Control Software RGB Delay Times 4 The RGB delay time switches the video off before switching the sync off. It then switches the sync for the new input before switching the video on. This assures a stable image on the screen. RGB Delay can be set from this Windows panel. Slide the scroll bar to select from 0 seconds to 5 seconds, in 0.5 second steps. 5 These options may not be the same on all systems. Each one is explained in the Help screen by clicking on the panel option.

System 5cr Switcher User’s Manual B cr Options Installing System 5cr Projector Power Sensor Infrared Broadcaster SCP 100 Remote Pads Glossary of Terms Index
Reference • Appendix B cr Options System 5cr 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.
Appendix B • Reference 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 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 – The decrease in magnitude (of a signal).
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.
