Accessing the Inside Contents Chapter One • Introduction and Features Changing Jumper Settings There are three jumpers in the RGB 202xi which can be changed by the user for special applications. They are: _ Note of the position of the jumper before changing it. J23 – TTL colors (3-pins) 1 to 2 = 64 TTL Colors (EGA) 2 to 3 = 16 TTL Colors (CGA) Open (2 only) = Automatic Detect (Default) The interface normally produces the proper TTL colors. J26 – Negative Sync (2-pins) 1 to 2 = Sync negative only.

Introduction • Features and Specifications About this manual Reference Information Problem This manual was written to explain the features, installation and operation of Extron’s RGB 202xi series of interfaces. Although the name “RGB 202xi” is used throughout the manual, it refers to four different interface models. Chapter 4 covers the differences between the standard model RGB 202xi and those models with special features.
Troubleshooting Reference Information Due to the number of different types of Data Projectors and Data Monitors currently on the market, each with different characteristics, no specific data display device was used to generate this troubleshooting information. If you have a concern or would like to know any special or unusual characteristic of your particular display, please call Extron. Problem Probable Cause No image on Data 1. Power Connections Display (projector not being made. or monitor).
Introduction • Features and Specifications Reference Information Features Defined Quick Reference Guide 1 Auto Power – In normal operation, the RGB 202xi is “green” or in “power saver mode” because it turns on only when it is needed. If it senses computer sync on its selected input, the RGB 202xi turns ON. Also, when the selected input senses no sync from that computer, it turns itself OFF. The LED lights when the RGB 202xi power is on.
Quick Reference Guide Reference Information Introduction • Features and Specifications LCD Sync Processing – Exclusive to Extron, our LCD sync processing makes the RGB 202xi work with CRT and LCD based presentation displays. Input Switch – The RGB 202xi interface can be connected to the outputs of two computers at the same time, making it a two-input switcher as well as an interface. The Input switch is used to select which input source (#1 or #2) will be displayed on the connected monitor or projector.

Notes Related Parts and Accessories BNC High Resolution Cables Extron recommends High Resolution BNC cables with signal frequencies greater than of 25 kHz or when using a computer with a frequency of 15135 kHz and running distances of 100 feet or more.
Related Parts and Accessories Monitor Breakout Cables Extron MBC “Monitor Breakout Cables” feature monitor loop-through connector for providing local monitor viewing. Below is a sample listing of Extron’s most popular MBC and ICWK cables for use with the RGB 202xi interface. Because this is only a partial listing, please call Extron for any assistance to interface a computer that may not be listed.
Rear Panel Connections Inputs 1 and 2 (Computer-Video) Analog/TTL – This 9-pin input is for any TTL Computer with a horizontal scan frequency of 15-135 kHz. This is for use with Extron MBC cables only. 1 2 Analog/ECL – This 9-pin input is for any analog or ECL input computer source with a horizontal scan frequency range between 15-135 kHz. This is for use with Extron MBC cables only. Pin assignments for the two connectors are: Pin Input #1 Signals 1. Ground 2. Red Prime 3. Red Video 4.
Related Parts and Accessories Computer-to-Interface Connections As illustrated below, there are many ways to connect a computer to an interface, depending on the application. This section discusses some of the possibilities. COMPUTER LOCAL MONITOR COMPUTER OR PC Rear Panel Connections Audio Connections The RGB 202xi provides audio switching (together with the video input) to the audio output which is connected to the user’s audio equipment. The user also supplies the audio cables.
Rear Panel Connections _ This section describes function of each connector. Rear Panel DIP switches are covered in Chapter 3. RGB 202xi, RGB 202 VTG, RGB 202 VS2 and RGB 202 VS SL2 User’s Manual 1 REMOTE 2 BNC Outputs with Auto Sync The RGB 202xi converts all computer video to RGB Analog signals, with outputs on the rear panel BNC connectors. With all of the DIP switches in the OFF position, the RGB 202xi is in the “Auto Sync” mode.
RGB 202 Model Differences Rear Panel Connections Sync Polarity – VGA, for example, has three modes of operation. Each of these modes has a different polarity (positive or negative combinations) configuration. The RGB 202xi tracks these mode polarity changes and sends out the polarity exactly as it is came in. Thus, if horizontal sync comes in positive and the vertical sync is negative they will go out the same way.
Notes RGB 202xi Model Differences Making ShiftLock™ Cables Extron supplies connectors for making ShiftLock cables; the user supplies the cable. Twisted pair cable may be used – up to 50 feet in length. The illustration below shows the steps for a making a cable using twisted pair. Do each step for both ends of the cable. Make as many cables as required. ___ Although the color of the wire is not important, however you must use the same wire color assignments for each end of the cable. 1.
RGB 202 Model Differences RGB 202 VS SL2 (VideoShift™ and ShiftLock™) The VS SL2 model includes both VideoShift™ and ShiftLock™ features. The VideoShift™ controls are on the front panel and the ShiftLock™ controls are on the back panel. The VideoShift is the same as that described for the VS2 model. The ShiftLock™ feature allows two or more RGB 202 VS SL2 units to be linked together, such that one of the units controls the VideoShift for all.
Operation • Controls and Indicators Operating the RGB 202xi RGB 202xi Model Differences RGB 202 VS2 (VideoShift™) This chapter covers the function of the controls and indicators on the RGB 202xi, including some examples on how they are used. __ If there are any difficulties setting up for the desired results, see Appendix B for troubleshooting information. The VS2 model includes Extron’s VideoShift™ feature. The front panel for the RGB 202 VS2 is shown below.
RGB 202xi Model Differences There are three other models of the RGB 202xi, each of which has additional features. This chapter covers only those differences; all standard features are in the other sections. RGB 202 VTG (Video Test Generator) This model includes some of the features of Extron’s Video Test Generators. On the front panel (shown below) there is a section marked “Mini VTG”.
Operation • Controls and Indicators Picture Centering Controls These two knobs are used to make four separate adjustments. The RGB 202xi has memories for each of its two inputs. Turning a knob not only moves the image but it also stores that information in the memory for the selected input. When switching between inputs, or when power is OFF, each memory keeps the centering information that was last set. This means that centering for each of the two inputs need only be set once for an application.
Operation • Controls and Indicators Laptop, Notebook or Portable Applications – Video from these computers may be quite different from standard PCs or Macs because they were designed to use an LCD screen instead of a CRT monitor.
Operation • Controls and Indicators #3 - Sync Output Off = Auto Sync Processing. On = Force separate Horizontal and Vertical Sync output, regardless of cable connections. This feature may be used when the display device does not have a sync impedance that is low enough to be detected by the Auto Sync feature. #4 - Auto Power Defeat Off = Auto Power detect On = Auto Power defeat forces RGB 202xi power On. This turns the interface on permanently while it is connected to an active AC power source.
