Extron’s RGB 118 & RGB 118 PLUS User’s Manual 2 Chapter Two Operation of RGB 118 & RGB 118 PLUS Front Panel Top Panel Internal DIP Switches Using the SRI Extron • RGB 118 & RGB 118 PLUS • User’s Manual
Operation Operation of RGB 118 and RGB 118 PLUS Front Panel The following descriptions are keyed* to the RGB 118 PLUS drawings below and on the facing page. A SRI Pushbutton Switch (RGB 118 PLUS ONLY) Push and hold this button in to enable the RGB 118 PLUS SCANRATE LCD to display the horizontal and/or the vertical scan rate frequency of a monitor (See Using the SRI on Page 2-5 for details).
Operation Top Panel H Blue Enhance Control (Valid for TTL input only) This control allows adjusting a blue text display to an easier to read blue-green color. I Scan Rate Indicator (SRI) LCD Panel (RGB 118 PLUS ONLY) The LCD panel displays a monitor’s horizontal or vertical scan rate frequency. J V = Vertical Scan Rate (RGB 118 PLUS ONLY) Indicates vertical scan rate is currently being monitored. K H = Horizontal Scan Rate (RGB 118 PLUS ONLY) Indicates Horizontal scan rate is currently being monitored.
Operation Internal DIP Switches Internal DIP switch settings determine the operating mode of the RGB 118 and RGB 118 PLUS. Changing the switch settings requires removal of the top and bottom halves of the case as described below. Opening the RGB 118 or RGB 118 PLUS Case To open the RGB 118 or RGB 118 PLUS case, remove the screw from the bottom of the case (see Figure 1 on facing page). This enables removal of the top and bottom halves of the case as shown in Figure 2.

Operation Using the SRI (RGB 118 PLUS only) The SRI feature of the RGB 118 PLUS is used to determine the approximate horizontal and vertical scan frequencies of video and computer monitors. To use the SRI, hold the RGB 118 PLUS with the feet against the face of the monitor and near the center of the screen as shown in Figures 1 and 2 below. To view the vertical scan frequency, hold the unit so the LCD readout is on a vertical plane (red SRI button is in the uppermost position) as shown in Figure 1.

Applications Applications Following are possible applications for the RGB 118 and/or the RGB 118 PLUS. 1. As a Sync Stripper Using an MBC RGBS cable1, the RGB 118 can be used to strip Sync from Green and separate to Green and Composite Sync outputs. • Connect the RGB with sync on green signal to MBC RGBS cable. • Insert the MBC RGBS cable into the 9 pin input of the RGB 118. • Use the video and sync outputs of the interface as normal. 2.
Applications Application Diagrams The application diagram below (Figure 1) demonstrates an RGB 118 Interface used to interface a PC Computer monitor to a large screen data monitor which could be located in the same room or in a different location up to 150’ away.
Applications The application diagram below (Figure 1) demonstrates an RGB 118 PLUS combined with a Hi Res ECL Buffer and an MBC SUN/ APOLLO MONO cable to interface a high resolution computer/ monitor workstation to a large screen projector.

Glossary Glossary Bandwidth - For video amplifiers, bandwidth is a measure of the range of frequencies that make up the components of video character information within which a video amplifier will respond. The frequency range (passband) is usually measured between the half-power (3-dB) points on the video amplifier amplitude output response vs. frequency curve for a wide range of frequencies while maintaining a constant input signal amplitude for each frequency. CGA - Color Graphics Adapter.
Glossary Peaking - Peaking compensates for mid and high frequency RGB Video Bandwidth response in data monitors and projectors and for signal losses due to cable capacitance. When using the Peak enhancements on the RGB 118 and RGB 118 PLUS interface, please use the following guidelines for proper output settings: __ Use with all computer frequencies between 15-125 kHz at any cable length. __ Use with high frequency computers of 36 kHz or higher with cable lengths 75 feet or greater.
