RGB 201 Rxi Universal Interface • Introduction

1-2

The interface is rack and furniture mountable and has an

internal switching power supply for worldwide power

compatibility.

Features

Flexible mounting options — The RGB 201 Rxi can be rack

mounted, mounted under a desk or podium, or mounted

through a desk or other furniture with optional mounting

kits.

Audio — The interface outputs unbalanced PC stereo audio

inputs as line level, balanced stereo or mono audio.

Level (boost) and peaking controls — Separate front panel

controls compensate for signal losses from long cable

runs.

Horizontal and vertical centering controls — Separate front

panel controls allow horizontal and vertical centering

adjustments.

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 option maintains a stable sync

signal while allowing centering control. This interface

also provides another option, Digital Display Sync

Processing (DDSP^™), to ensure proper displays without

altering sync pulse timing or width. The sync processing

type is selected via a rear panel DIP switch.

Digital Sync Validation Processing — In critical environments

or unmanned, remote locations, it is vital to know which

sources are active. Extron’s exclusive DSVP conﬁrms that

input sources are active by scanning all sync inputs for

active signals. DSVP provides instantaneous frequency

feedback for composite sync or separate horizontal and

vertical sync signals via the interface’s Remote port.

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.

RGB 201 Rxi Universal Interface • Introduction

Introduction, cont’d

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

format via cabling setup, rear panel DIP switch, and/or

internal DIP switch conﬁguration.

•

Sync on green — Sync can be added to the green video

signal, for an RGsB video output, by turning on a rear

panel DIP switch.

Sync on red, green, and blue — Sync can be added to the

red and blue video signals, for an RsGsBs video output,

by turning on internal DIP switches and a 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 an internal jumper.

Vertical sync pulse width adjustment — Vertical sync pulse

width can be adjusted via a rear panel DIP switch.

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 interface normally outputs sync simultaneously as

separate horizontal and vertical sync and as composite

sync, but sync on green (SOG) and sync on red, green, and

blue can be selected on rear panel and/or internal DIP

switch(es).

Installation and Operation

Installation 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 201 Rxi interface, follow these basic

steps:

Sync polarity, sync-on-red and sync-on-blue, and video

clamp conﬁguration require opening the interface’s case

and should be done before the interface is mounted.

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.

If you want the interface to always output positive sync

or negative sync, rather than following the input sync

polarity, open the interface and shift the internal jumpers

as necessary. See Internal Conﬁguration and its subsection,

Sync polarity jumpers, in this chapter.

If you want the interface to output RsGsBs video, open the

interface and shift the internal DIP switches as necessary.

See Internal Conﬁguration and its subsection, Internal sync

DIP switches (RsGsBs), in this chapter.

If you want the clamp the sync timing of the video output

to the sync tip rather than the back porch, open the

interface and shift the internal jumper as necessary. See

Internal Conﬁguration and its subsection, Video clamping

jumper, in this chapter.

Install the rubber feet for tabletop use, or install the

appropriate brackets and furniture or rack mount the

interface. See Mounting the Interface in this chapter.

Connect the inputs (computers), output (display, local

monitor, and audio), and remote control. See Rear Panel

Connections and Switches in this chapter.

Set the rear panel DIP switches. See Rear Panel Connections

and Switches in 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.

Adjust horizontal and vertical centering, and also level

and peaking to obtain the best picture.

the jumper as follows:

Locate J9, J20, and J21 on the printed circuit board.

For sync follow (output sync polarity identical to the

input sync), ensure that the jumper is removed from

jumper block J21.

For positive or negative sync, ensure that a jumper is

installed in jumper block J21 and conﬁgure J9 and J20 as

follows:

Horizontal sync —

For positive sync, install a jumper in block J9.

For negative sync, remove the jumper from block J9.

Vertical sync —

For positive sync, install a jumper in block J20.

For negative sync, remove the jumper from block J20.

RGB 201 Rxi Universal Interface • Installation and Operation

Internal sync DIP switches (RsGsBs)

The interface is factory conﬁgured to strip all sync signals from

the red, green, and blue video input signals and to output

horizontal and vertical sync separately(RGBHV) or as composite

sync (RGBS). Sync on green (SOG or RGsB) can be selected on a

rear panel DIP switch. Sync on red, green and blue (RsGsBs) can

be selected on internal DIP switches.

Locate DIP switch SW2 on the printed circuit board.

Use a Tweeker or other small screwdriver to toggle the

DIP switches between the on/closed or off/open positions.

For RGBHV, RGBS, or RGsB video, ensure that both

switches on the DIP switch block are off.

For RsGsBs video —

Ensure that both DIP switches are on.

Turn the rear panel SOG DIP switch on (up).

When both switches on the internal DIP switch SW2

are on, the rear panel SOG switch controls the output

format. When the SOG switch is on, the interface

outputs RsGsBs video; when the SOG switch is off, the

interface outputs RGBHV and RGBS video.

Horizontal sync —

For positive sync, ensure that a jumper is installed in

jumper block J9.

For negative sync, ensure that the jumper is removed

from jumper block J9.

Vertical sync —

For positive sync, ensure that a jumper is installed in

jumper block J20.

For negative sync, ensure that the jumper is removed

from jumper block J20.

Video clamping jumper

The interface is factory conﬁgured to clamp the sync timing to

the back porch. To clamp the sync timing to the tip of the sync

pulse, reconﬁgure the jumper as follows:

Locate J11 on the printed circuit board.

For sync timing clamped to the back porch, ensure that a

jumper is in place from pin 1 to pin 2.

For sync timing clamped to the sync tip, ensure that a

jumper is in place from pin 2 to pin 3.

Rack mounting

UL guidelines for rack mounting

The following Underwriters Laboratories (UL) guidelines are

relevant to the safe installation of these products in a rack:

Elevated operating ambient temperature — If the unit

is installed in a closed or multi-unit rack assembly, the

operating ambient temperature of the rack environment

may be greater than room ambient temperature. Therefore,

install the equipment in an environment compatible with

the maximum ambient temperature (Tma: +122 °F, +50 ° C)

speciﬁed by Extron.

Reduced air ﬂow — Install the equipment in the rack

so that the equipment gets adequate air ﬂow for safe

operation.

Mechanical loading — Mount the equipment in the rack

so that uneven mechanical loading does not create a

hazardous condition.

Circuit overloading — Connect the equipment to

the supply circuit and consider the effect that circuit

overloading might have on overcurrent protection and

supply wiring. Give appropriate consideration to the

equipment nameplate ratings when addressing this

concern.

Reliable earthing (grounding) — Maintain reliable

grounding of rack-mounted equipment. Pay particular

attention to supply connections other than direct

connections to the branch circuit (such as the use of power

strips).

Rack mounting procedure

If feet were installed on the bottom of the interface, remove

them.

Place the interface on one half of the 1U (one unit high,

19" wide) optional rack shelf (part #60-190-01). Align the

front of the interface with the front of the shelf, and align

the threaded holes on the bottom of the interface with the

holes in the rack shelf (ﬁgure 2-5).

DIP switches — This bank of DIP switches is used to conﬁgure

the interface. The switches control:

•

DDSP or ADSP

SOG (sync on green)

Serration pulses

Vertical sync pulse width

Mono or stereo audio

Backlight illumination.

Monitor ID bit termination

To set the sliding-type DIP

switches, use a Tweeker or small screwdriver to slide the

switch to the on/up/closed or off/down/open position.

The default for all DIP switches is Off (down).

1 — DDSP

DDSP disables all sync processing. This feature may be

necessary for digital display devices such as LCD, DLP

(digital light processor), and plasma displays. Use this

option if the image is not displayed properly after other

options, such as serration pulse and video termination

changes, have been tried.

Up — The interface uses DDSP instead of ADSP. DDSP

does not process the sync signal.

DDSP disables the horizontal and vertical centering

controls.

Down — The interface performs sync processing

operations, such as centering, with ADSP.

2 — Sync on green

Up — The interface outputs a composite sync signal on top

of the green video signal (SOG) via the G output connector

(RGsB).

Down — The interface outputs separate horizontal and

vertical sync (on the H and V connectors) and composite

sync (on the S connector) for RGBHV or RGBS.

3 — Serration pulses — Many LCD and DLP projectors and

plasma displays will not display properly if serration

pulses are present in the sync signal. Flagging or bending

at the top of the video image is a sign that the serration

pulses should be removed.

RGB 201 Rxi Universal Interface • Installation and Operation

2-13

Installation and Operation, cont’d

Up — The interface outputs serration pulses in the vertical

sync interval.

Down — The interface does not output serration pulses.

4 — Vertical sync pulse width — For some digital displays, if:

•

no picture appears,

the picture cuts in and out,

the picture is scrambled,

try adjusting the output vertical sync pulse width or

switching from ADSP to DDSP.

If the interface receives a typical (0.7 volts p-p) analog

computer video input, the output is as follows:

•

At the minimum level setting (the counterclockwise limit of

this control), the interface outputs video at 0.5 volts p-p.

Unity level is 0.7 volts p-p, the same as the input signal.

Set the control to just before the boost range (indicated

by the red line on the interface, the shaded area on the

illustration on the previous page) to output unity level

video.

RGB 201 Rxi Universal Interface • Installation and Operation

2-16

•

At the maximum level setting (the clockwise limit of this

control), the interface outputs video at 1.45 volts p-p.

Select a setting in the boost range (0.7 volts and above),

to compensate for the decrease in signal level that occurs

when the signal passes through long cables.

Set the boost at 100% (the maximum level) for cable

lengths over 500 feet for all computer signals of 15 kHz to

150 kHz.

Peaking (Peak) control — Peaking affects the sharpness of a

picture. Increased peaking can compensate for detail (mid- and

high-frequency) loss from low bandwidth system components

or capacitance in long cables. The minimum setting (at the

counterclockwise limit) provides no peaking. The maximum

setting (at the clockwise limit) provides 100% peaking. Adjust

this control while viewing the displayed image to obtain the

optimum picture sharpness.

Centering controls

Many projectors store centering information in their own

memories based on signal frequency. When a projector displays

video from different input sources that have the same frequency,

one source’s images may not be centered. Using the interface’s

centering controls eliminates that problem.

{

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 item

[

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 DIP switch 1 (DDSP) is set to On

and either centering control is rotated, the LCD displays

N/A DDSP ON.

To use the display’s centering controls rather than the

interface’s controls, set the DDSP DIP switch to On.

RGB 201 Rxi Universal Interface • Installation and Operation

2-17

Installation and Operation, cont’d

The centering controls have no mechanical limits to

rotation. When the minimum or maximum limit of

the control is reached, LCD indicates the horizontal or

vertical shift limit has been reached and the picture stops

moving on the screen.

Centering memory

Turning the centering knobs not only moves the images, but it

also stores the horizontal and vertical centering setting in the

interface’s memory. The interface recalls the centering settings

each time it detects a change in the input frequency. Centering

adjustments only need to be set once for an application because

the settings are saved even when the power is off.

LCD display

LCD display — The LCD displays the horizontal and vertical

scanning rates of the input signal and indicates the horizontal

and vertical centering status and limits.

LCD screen backlight

The LCD backlights for 15 seconds at power-up, and it remains

backlit as long as an input signal is present. To force the

backlight to remain off at all times except at power-up, set DIP

switch 6 (No Backlight) on the rear panel to On (up).

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

DIP switch 6 is set to On (up), 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 indications

{

[

While the vertical ( ) or horizontal ( ) centering (shift)

controls are being adjusted, the LCD displays H-SHIFT or

V-SHIFT. That message remains on the LCD (in place of the

scan rates) until the centering control has been inactive for

3 seconds.

RGB 201 Rxi Universal Interface • Installation and Operation

2-18

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.

Once the centering controls are no longer active, the centering

settings are saved, and the LCD displays the current scan rates.

If DIP switch 1 (DDSP) on the rear panel is set to On (right) and

a centering control is rotated, the LCD displays N/A DDSP ON,

and the image does not shift on screen.

Troubleshooting

Turn on the input device (computer, audio device) and output

device(s) (projector, monitors, speakers) and plug in the

interface’s AC power cord. The image should now appear on

the screen, and sound should be audible.

If the image does not appear or there is no sound

Ensure that all devices are plugged in.

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.

Check the cabling and the audio connector wiring and

grounding, and make adjustments as needed.

For digital display devices (including LCD, DLP and

plasma devices), try turning DIP switch 1 (DDSP) On (up)

or Off (down) on the rear panel.

To test the system setup and output, substitute a stand-

alone video test generator (VTG) for the computer input.

Unplug the power cords to the input and output devices

and the interface, replace the video source with a VTG,

then reconnect power cords to restore AC power.

Call the Extron S³Sales & Technical Support Hotline if

needed.

If the image is not displayed correctly

If the output image looks too green, the sync on green

(SOG) DIP switch (switch 2) may be set to On (up), and

the display device may not be conﬁgured to handle SOG

signals. Set the switch to Off (down).

If the picture bends or ﬂags at the top of the screen, set the

serration pulse DIP switch (switch 3) to Off (down).

For a display device that experiences intermittent glitches,

try turning DDSP On (up) or Off (down) using DIP switch

1 on the rear panel.

Installation and Operation, cont’d

If the picture “hangs off” the edges of the screen, adjust the

centering controls ( , ).

[{

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.

If the image still does not display correctly, call the Extron

S³Sales & Technical Support Hotline.

If the interface does not respond to controls

If the picture does not move on screen when the horizontal and

vertical centering controls are rotated, DDSP is in use. Set DIP

switch 1 (DDSP) on the rear panel to Off (down).

If the image is not correctly centered

If the picture from a new source computer does not seem

correctly centered, the input position memory presets might

require resetting. Reset the input position memories as follows:

Unplug the interface’s AC power cord.

Open the interface. See Internal Conﬁguration in this

chapter.

Install a jumper in jumper block J22 (ﬁgure 2-2).

Plug in the interface’s AC power cord, wait approximately

5 seconds, and then unplug the AC power cord.

Remove the jumper installed in step 3.

Replace the interface’s cover and reinstall the screws.

Plug in the interface’s AC power cord.

Select the appropriate input, and adjust the horizontal and

vertical centering.

Simple Instruction Set Control

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.

Interface-initiated messages

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).

]

The interface displays the copyright message when it ﬁrst

powers on. Vx.xx is the ﬁrmware version number.

]

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.

RGB 201 Rxi Universal Interface • Remote Control

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:

E10 – Invalid command

E13 – Invalid value (the number is out of range/too large)

Timeout

Pauses of 10 seconds or longer between command ASCII

characters result in a timeout. The command operation is

aborted with no other indication.

The command/response table is on the next page. Lower case

letters are allowed in the command ﬁeld only as indicated.

Control Software for Windows

The included RGB 201 control program, graphical control

software for Windows, offers another way to control the

interface. The control software is compatible with Windows 3.1,

3.11, 95/98, and above.

Installing the software

The control program is contained on a set of 3.5-inch diskettes,

and, if you choose to use it, must be installed on and run from

the hard drive.

To install the software onto the hard drive, run SETUP.EXE from

the installation disk #1, and follow the instructions that appear

on the screen. The program requires approximately 1.5 MB

(megabyte) of hard disk space.

By default the installation creates a C:\RGB201 directory, and it

places two icons (RGB 201 Control Pgm and RGB 201 Help) into

a group or folder named “Extron Electronics”.

Using the software

To run the control program, follow these steps:

Double-click on the RGB 201 Control Pgm

icon in the Extron Electronics group or

folder, or on the Rgb201.exe icon in the

C:\RGB201 directory. The Comm menu

appears on the screen.

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

RS-232 port. The control software checks for the interface

at that port and reads its conﬁguration.

The control program window (Figure 3-2) appears and

displays current settings.
