Introduction

About this Manual

This manual contains information about the Extron RGB 202 Rxi and RGB 202 Rxi VTG universal interfaces and on how to operate and configure them.

About the RGB 202 R

The RGB 202 Rxi is an analog computer-video interface with 300 MHz (-3dB) video bandwidth and Advanced Digital Sync Processing™. It accepts two computer-video and two unbalanced computer stereo audio inputs. It also features one RGBHV, RGBS or RGsB output and one balanced, line level stereo audio output. The RGB 202 Rxi VTG is identical to the RGB 202 Rxi except that it also contains a built-in video test generator (VTG).

Front panel controls, remote contact closure, or an RS-232 remote control system or computer can be used to select between inputs.

Features

Features of both models

Flexible mounting options — The RGB 202 Rxi and

RGB 202 Rxi VTG can be rack mounted, mounted under a desk or podium, or mounted through a desk or other furniture with optional mounting kits.

Stereo audio — Unbalanced PC stereo audio inputs are output

as line level, balanced stereo audio.

Level (boost) and peaking controls — Separate front panel

controls compensate for signal losses from long cable runs.

Horizontal and vertical centering controls — These front panel

controls allow separate horizontal and vertical centering adjustments.

Digital sync processing — Using regular sync processing to

allow centering control (H-shift or V-shift) can create problems with some digital display devices as a result of the sync delay. Extron’s ADSP™ (Advanced Digital Sync Processing™) maintains a stable sync signal while allowing centering control. These interfaces also provide another option, DDSP™ (Digital Display Sync Processing™), to ensure proper displays without altering sync pulse timing or width. The sync processing type is selected via a rear panel DIP switch.

Thirty memory presets — Thirty spaces are reserved in the

interface’s memory for storing user-defined combinations of horizontal and vertical position settings based upon input signal scan rates. The interface automatically recalls the position settings when it detects an input signal with a matching scan rate.

LCD scan rate indicator — This backlit liquid crystal display

(LCD) indicates the horizontal and vertical sync rates, and the minimum and maximum centering limits. A DIP switch is provided for turning off the backlight.

MBC power jacks — These jacks provide power to buffered

monitor breakout cables.

75 ohm video termination switches — Rear panel DIP switches

provide a way to switch between high Z and 75 ohm video input termination for systems where a local computer monitor is not used.

RGBHV, RGBS, or RGsB outputs — Select the output format

via cabling setup and rear panel DIP switch.

Serration pulse switch — This DIP switch-selectable feature

adds or strips the serration pulses from the output signal to make it compatible with digital display devices. Use the serration pulse switch if flagging or bending occurs at the top of the video display.

Sync polarity adjustment — Horizontal and vertical sync

output can either follow input sync polarity, or outgoing sync can be forced to negative via a rear panel DIP switch.

Vertical sync pulse width adjustment — Vertical sync pulse

width can be adjusted via a rear panel DIP switch.

Remote control input selection — Connect a remote contact

closure keypad, an RS-232 control system, or a computer to the rear panel RS-232 port to remotely control the interface.

Vented metal enclosure — Vents in the enclosure keep the

interface cool and ready for use 24 hours a day, 7 days per week.

Automatic sync stripping — Sync signals are automatically

stripped from the red, green and blue video input signals. The interfaces output sync simultaneously as separate horizontal and vertical sync and as composite sync, but sync on green (SOG) can be selected via a rear panel DIP switch.

Installation and Operation Overview

This is an overview of the installation process. You will find detailed installation and operation instructions in this chapter.

To install and set up the RGB 202 Rxi and RGB 202 Rxi VTG interfaces, follow these basic steps:

Turn all of the equipment (computers, remote controls,

interface, projector/monitor, local monitor, and speakers or other audio device) off. Disconnect the power cords from the power source.

Install the rubber feet for tabletop use, or install the

appropriate brackets and furniture or rack mount the interface. See “Mounting the Interfaces” in this chapter.

Attach the input (computers), output (display, local

monitor and audio), and remote control cables. See “Cabling” in this chapter.

Set the rear DIP switches. Use the “Rear Panel” section of

this chapter as a guide.

Connect power cords and turn on the devices: output

devices (projector, monitors, speakers), remote control device, interface, and source computers.

Select an input from the front panel toggle switch or the

remote control (keypad, system, or PC).

Tabletop/desktop placement

For tabletop or desktop placement only, install the self-adhesive rubber feet/pads (provided) onto the four corners of the bottom of the interface enclosure.

Under-desk mounting

1. Attach the optional under-desk mounting brackets (part #70-077-01) to the interface with the six machine screws (provided in the mounting kit), as shown below.

2. Hold the interface with attached brackets against the underside of the desk or other furniture. Mark the location of holes for screws on the desk.

3. Drill 1/4” (6.4 mm) deep, 3/32” (2.38 mm) diameter pilot holes in the table or desk at the marked screw locations from the underside/inside (concealed side) of the furniture, where the interface will be located.

4. Insert the four wood screws into the pilot holes. Fasten each screw into the installation surface until just less than 1/4” of the screw protrudes.

5. Align the installed screws with the slots in the mounting brackets, and place the interface against the surface, with the screws through the bracket slots.

6. Slide the interface slightly forward or back, then tighten all four screws to fasten it in place.

The image should now appear on screen, and sound

should be audible. If not, ensure that all devices are plugged in and receiving power. Check the cabling and switch settings, and make adjustments as needed. Select a different input (or the VTG) to check for a picture and sound.

If problems persist, see “Troubleshooting” in this chapter, then call Extron’s customer support hotline, if needed.

Adjust horizontal and vertical centering, and also level

and peaking to obtain the best picture.

For the RGB 202 Rxi VTG, set up and test the VTG. See

“Operating the VTG” in this chapter.

Vertical centering ( ) — While viewing the displayed image,

rotate this control to move the image up or down on the screen. During centering adjustment, the LCD displays V-SHIFT, and it indicates the vertical shift minimum or maximum limit when the centering limit has been reached. See the notes below.

Horizontal centering ( ) — While viewing the displayed

image, rotate this control to move the image to the right or left on the screen. During centering adjustment, the LCD displays H-SHIFT, and it indicates the horizontal shift minimum or maximum limit when the centering limit has been reached.

DDSP disables the interface’s vertical and horizontal centering controls. If DDSP is set to On and either centering control is rotated, N/A DDSP ON appears on the LCD display. To use the display device’s centering controls instead of the interface’s centering, set the DDSP DIP switch to On.

The centering controls have no mechanical limits to rotation. When the minimum or maximum limit of the control is reached, the picture stops moving on screen.

Many projectors store centering information in their own memories based on signal frequency. When a projector displays video from input sources that have the same frequency, one source’s images may not be centered. Using the interface’s centering controls eliminates that problem.

Turning the centering control knobs not only moves the images, but it also stores the horizontal and vertical centering settings in separate memories for each selected input. The interface recalls the centering settings each time an input is selected. Centering adjustments only need to be set once for an application because the settings are saved even when the power is off.

VTG output resolution and pattern selection switch

(RGB 202 Rxi VTG only) — Select a combination of display resolution and video test pattern using this 16-position rotary switch. Four different video test patterns are available for each of the four resolutions offered by the RGB 202 Rxi VTG’s built-in mini video test generator. See “Operating the VTG” in this chapter for more information.

If DDSP is on and the horizontal or vertical centering control is rotated, the LCD displays N/A DDSP ON.

While the VTG is active (RGB 202 Rxi VTG only), the LCD displays the current format, resolution and scan rate settings. See the “LCD Display” section for details.

The backlight turns on at power-up, and it remains on for 15 seconds if a signal is not present at the selected input. If a signal is present, the backlight will remain on at all times. However, if the rear panel No Backlight DIP switch is set to On, the backlight will turn on for only three seconds at power-up, then it will remain dark even when an active signal is present.

2 — SOG (sync on green)

On — The interface outputs sync on green. Off — The interface outputs both separate horizontal and

vertical sync (on the H and V connectors) and composite sync (on the S connector) for RGBHV or RGBS, respectively.

3 — Serr (serration pulse) — Many LCD and DLP projectors

and plasma displays, must have serration pulses removed from the sync signal in order to be displayed properly. Flagging or bending at the top of the video image is a sign that the serration pulses should be removed.

On — The interface outputs serration pulses in the vertical

sync interval.

Off — The interface does not output serration pulses.

4 — Neg Sync — This switch controls sync polarity.

On — Both the horizontal and the vertical sync signals

are forced to negative polarity on output.

Off — Output sync polarity follows (is the same as) input

polarity.

5 — V Sync Width (vertical sync pulse width) — For some

digital display devices, if no picture appears, the picture cuts in and out, or it is scrambled, try adjusting the output vertical sync pulse width or switching from ADSP to DDSP.

On — The vertical sync pulse is narrow. Off — The vertical sync pulse is wide.

6 & 7 — 75 Ohm (video input termination) — DIP switches

6 and 7 provide termination for video inputs 1 and 2, respectively. Video termination can be accomplished by using a laptop breakout cable, by connecting a termination adapter or a local monitor to a monitor breakout cable (MBC), by using an MBC buffer cable, or by setting a termination switch on the interface.

DIP switches 6 and 7 provide a termination method to prevent blooming when a monitor breakout cable is used but no local monitor or termination adapter is connected.

On — The interface provides 75 ohm video input

termination.

Off — The interface provides high Z (high impedance)

video input termination.

LCD Display

The RGB 202 Rxi and RGB 202 Rxi VTG’s front panel LCD display serves two main functions: to display the scanning rates of the input signal, and to indicate the horizontal and vertical centering limits. During VTG operation, the RGB 202 Rxi VTG’s LCD displays the VTG format, resolution and refresh rates.

LCD screen backlight

The LCD screen lights for 15 seconds at power-up, and it stays backlit as long as an input signal is present at the selected input. To force the backlight to remain off at all times except at powerup, set the rear panel No Backlight DIP switch to On. See page 2-11 for details.

Scan rate indication

When the interface is powered on, the LCD lights for 15 seconds while it determines whether an input sync signal is present. If the No Backlight DIP switch is set to On, the LCD lights for three seconds only.

• If the interface does not detect an input sync signal, the LCD goes dark and displays “NO SIGNAL” until the interface receives an active sync signal.

• If the interface detects an input sync signal, the LCD displays the horizontal and vertical scan rates (sync frequencies) in the following format:

Hxxx.xxk Vxxx.xHz

The first line shows the horizontal rate in kilohertz, and the second line shows the vertical rate in Hertz.

Centering

While the vertical ( ) or horizontal ( ) centering (shift) controls are being adjusted, the LCD displays “H-SHIFT” or “V-SHIFT”, respectively. That message remains on the LCD (in place of the scan rates) until the centering control has been inactive for 3 seconds. When a centering control reaches its minimum or maximum limit, the LCD displays “MIN” or “MAX” on the line below “H-SHIFT” or “V-SHIFT”.

If the centering controls are no longer active, the centering settings are saved, and the LCD displays the current scan rates.

If the DDSP DIP switch is set to On and a centering control is rotated, the LCD displays N/A DDSP ON, and the image does not shift on screen.

Operating the VTG (RGB 202 R

The RGB 202 Rxi VTG includes a limited video test generator. The VTG creates and outputs standard test patterns at fixed formats and resolutions so that a system can be set up and tested even when an input computer is not available.

To use the VTG, follow these steps:

1. Set the front panel 202/VTG selection switch to VTG.

2. Select an appropriate combination of output resolution

and test pattern using the 16-position rotary switch on the front panel. Four different video test patterns are available for each of the four resolutions. Select the test patterns by rotating the switch within the appropriate resolution quadrant. The LCD displays the selected VTG format, the resolution, and then the scan rates.

The test patterns are shown below.

Left to right: crosshatch, H-pattern, 8 split-level grayscale, and 8 color bar test patterns

The four available resolutions are shown below.

Troubleshooting

Turn on the input devices (computer, audio device) and output device(s) (projector, monitors, speakers). The image should now appear on the screen, and sound should be audible.

If the image does not appear or there is no sound

1. Ensure that all devices are plugged in.

2. Make sure that each device is receiving power. The

interface’s front panel LED lights if the interface is receiving power and an active sync signal.

3. Check the cabling and the audio connector wiring and grounding, and make adjustments as needed.

4. Verify that the 75 ohm video input termination DIP switches have been set correctly.

5. For digital display devices (including LCD, DLP and plasma devices), try turning DDSP on or off using the rear panel DIP switch.

6. To test the system setup and output, substitute a video test generator for one of the computer inputs. Use the VTG that is built into the RGB 202 Rxi VTG, or use a stand-alone VTG with the RGB 202 Rxi. To use a stand-alone VTG, unplug the input/output devices’ and interface’s power cords, replace the video source with a VTG, then reconnect power cords to restore AC power.

7. Call Extron’s customer support hotline if needed.

If the image is not displayed correctly

1. If the output image looks too green, the sync on green (SOG) DIP switch may be set to On, and the display device may not be configured to handle SOG signals. Set SOG to Off.

2. If the picture bends or flags at the top of the screen, set the serration pulse DIP switch to Off.

3. For a display device that experiences intermittent glitches, try turning DDSP on or off using the rear panel DIP switch.

4. If the picture “hangs off” the edges of the screen, adjust the centering controls (

5. If the edges of the image seem to exceed their boundaries or if thin lines and sharp edges look thick and fuzzy, try changing the Level/Boost or Peak Control settings. If the image is too bright, decrease the boost or peaking level.

, ).

6. If the image appears and is stable, but it has ghosting or blooming, check the high Z/75 ohm video input termination. If changing the termination doesn’t solve the problem, try using a different input cable.

7. If the picture is faint or cuts out and the signal is weak, the video input may be double-terminated. If a local monitor or a termination adapter is attached to the input’s monitor breakout cable, or if a laptop breakout cable is used, make sure that the 75 ohm video input termination DIP switches are set to Off (for high Z termination).

8. If the picture from a new source computer does not seem correctly centered, the input position memory presets might require resetting. To reset the input position memories, do the following:

a. Unplug the interface’s AC power cord. b. Hold the input selection switch up (toward input 1)

while reconnecting the power cord to the interface and the power source

c. Select the appropriate input, and adjust the

horizontal and vertical centering.

9. If the image still does not display correctly, call Extron’s customer support hotline.

If the interface does not respond to controls

1. If the picture does not move on screen when the horizontal and vertical centering controls are rotated, DDSP is in use. Set the DDSP DIP switch to Off.

2. If the RGB 202 Rxi VTG does not switch between inputs when a remote control is used, the front panel 202/VTG toggle switch might be set to VTG. Use the switch to select 202 in order to use a remote control.

When the 202/VTG switch is set to VTG, signals from input1 and input 2 are ignored; the interface’s internal video test generator provides a test pattern in place of the computer video input. Input selection (selection of input 1 or input 2) cannot be performed until the 202/VTG selection switch is set to 202.

Remote Control

There are three ways to control input selection and centering features of an RGB 202 Rxi /RGB 202 Rxi VTG interface: by using the front panel controls, by using an RS-232 remote control device, and by using a contact closure keypad.

RS-232 Programmer’s Guide

The interface can be remotely controlled via a host computer or other device (such as a control system) attached to the rear panel 9-pin D RS-232 connector. The protocol is 9600 baud, 1 stop bit, no parity, and no flow control.

The control device (host) can use either Extron’s Simple Instruction Set (SIS) commands or the graphical control program for Windows. RS-232 control software is included with the interface.

The rear panel RS-232 9-pin D female connector has the following pin assignments:

RS-232 function Contact closure Description

1 – Input 1 Select input #1 2 Tx – Transmit data 3 Rx – Receive data 4 – Input 2 Select input #2 5 Gnd Gnd Signal ground 6 – – Not used 7 – – Not used 8 – – Not used 9 – – Not used

Host-to-interface communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When a command is valid, the interface executes the command and sends a response to the host device. All responses from the interface to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

DB9 Pin Locations

Female

RECONFIG When a change is made via a front panel control or another operation occurs that must be written to a new memory block, the interface sends the reconfiguration message. No response is required from the RS-232 host, but the host may request a new status listing via the request information command (I/i). See the command/response table in this chapter for details.

Chn

The input number has been changed or,

for the RGB 202 Rxi VTG, the VTG has been turned on or off.

Error responses

When the interface receives a valid SIS command, it executes the command and sends a response to the host device. If the interface is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.

The error response codes and their descriptions are as follows:

E01 – Invalid input number (the number is too large or small;

occurs when attempting to select VTG mode via RS-232)

E06 – Invalid input selection (occurs when selecting an input when

the RGB 202 Rxi VTG is set to VTG mode) E10 – Invalid command E13 – Invalid value (the number is out of range/too large)

Using the command/response table

The command/response table lists valid command ASCII codes, the interface’s responses to the host, and a description of the command’s function or the results of executing the command. Lower case characters are acceptable in the command field only where indicated. The ASCII to HEX conversion table below is for use with the command/response table.

Interface-initiated messages

3-2

When a local event such as a front panel or contact closure selection or adjustment takes place, the interface sends a message to the host. No response is required from the host. The interface-initiated messages are listed here (underlined).

Control Software for Windows

The included graphical control software for Windows offers another way to control the interface via RS-232 in addition to the Simple Instruction Set commands listed on page 3-4. The control software is compatible with Windows 3.1x, Windows 95/ 98, and Windows NT. The RGB 202 Rxi and RGB 202 Rxi VTG use version 2.0 or higher of Extron’s RGB 302/304/202 Control Program, which is included with these interfaces.

Installing the software

The control program is contained on a 3.5-inch diskette, and it can run from the floppy drive. However, it is more convenient to run the program from the hard drive.

To install the software onto the hard drive, run SETUP.EXE from the floppy disk, and follow the instructions that appear on the screen. The program requires approximately 1 MB (megabyte) of hard disk space.

By default the installation creates a C:\RGB302 directory, and it places two icons (RGB 302+304+202 Control Pgm and RGB 302+ 304+202 Help) into a group or folder named “Extron Electronics”.

Using the software

To run the control program, follow these steps:

1. Double-click on the RGB 302 + 304 + 202 Control Pgm icon

in the Extron Electronics group or folder, or on the Rgb302.exe icon in the C:\RGB302 directory. The Comm menu will appear on the screen.

2. Click on the comm port that is connected to the interface’s

RS-232 port. The control software will “look for” the interface at that port and read its configuration. The control program window (shown at left) will appear and display current settings.

For information on program features, press the F1 computer key

or click on the Help menu from within the control program, or double-click on the RGB 302+304+202 Help icon in the Extron Electronics group or folder.
