Setup Guide — RGB 580xi

This guide provides basic instructions for an experienced

installer to set up and operate the Extron RGB 580xi.

Installation

Refer to the RGB 580xi User’s Manual for details.

CInstallation and service must be performed by authorized personnel only.

Step 1 — Powering down

Turn off or disconnect all equipment from power sources.

Step 2 — Mounting

Mount the interface as desired.

Step 3 — Video input

Connect an RGBHV, RGBS, RGsB, or RsGsBs analog video input to the

front panel 15-pin HD input connector. The pinout table is shown below.

jack.

Step 5 — Video output

Connect a display device to the rear panel video output BNC connectors, as shown below.

Step 6 — Audio output

Connect an audio device to the 3.5 mm, 5-pole captive screw connector for balanced or

unbalanced audio output. Wire the male connector as shown here.

CAUTION

For unbalanced audio, connect the

sleeve(s) to the ground contact.

DO NOT connect the sleeve(s) to the

negative (-) contacts.

Do not tin the wires!

Step 7 — Contact closure

For contact closure, connect an optional contact closure device to the front panel 5-pin, captive

screw connector. Making contact closure between pins A and B transmits a channel signal

through the rear panel RS-232 port. The RGB 580xi SI/CCSI AAP models provide one-button

contact closure operation. Wire the male connector as shown below on the left. The Extron

VGA and control cable assembly comes with the male control connector prewired, as shown at

right.

Step 8 — Setting the DIP switches

The DIP switches control DDSP (Digital Display Sync Processing),

serration pulse output, SOG (sync on green) output, vertical sync width,

sync polarity, and composite sync output. Moving a switch up sets it to On

and moving it down sets it to Off.

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

1 — DDSP (Digital Display Sync Processing) — This feature may be necessary for digital

display devices such as LCD, DLP (digital light processing) and plasma displays. Use this

option if the image is not displayed properly after other options, such as serration pulse

and vertical sync pulse width, have been explored.

On — The interface uses DDSP instead of ADSP.

DDSP does not process the sync signal.

NDDSP disables the horizontal shifting control.

Off — The interface performs sync processing operations, such as centering, with ADSP.

2 — Serr (serration pulse) — Many LCD and DLP projectors and plasma displays must

have serration pulses removed from the sync signal in order to display 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.

3 — SOG (sync on green)

On — The interface outputs sync on green.

Off — The interface outputs separate horizontal and vertical sync (on the H and

V connectors) for RGBHV.

4 — V-Sync Width (vertical sync pulse width) — For some digital display devices, if no

picture appears, the picture cuts in and out, or the picture 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.

5 — 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.

6 — Comp Sync — This switch controls composite sync output.

On — The interface outputs combined horizontal and vertical sync for RGBS.

Off — The interface outputs RGBHV or RGsB video.

Step 9 — RS-232 control

For two-way RS-232 communication, connect an RS-232 device (control system or PC) to the

3-pole captive screw connector. Software for RS-232 control is included with the interface.

Refer to the “Remote Control” section of chapter 3 of the user’s manual for further details.

Wire the male connector, as shown here.

Front Panel Adjustments

Video signals passing through long cable runs of over 125 feet (38.1 meters) can decrease

in strength, creating signal loss. The longer the cable, the greater the cable resistance and

capacitance, and the greater the level and peaking adjustments that will be required to

compensate for the resultant signal loss. These adjustments change the level and peaking of the

output signal to compensate for capacitance caused by up to 1000 feet (304.8 meters) of Extron

SHR cable.

NIf the displayed image is too bright or too dark, try changing the level setting. If the edges

of the displayed image seem to exceed their boundaries, or if thin lines and sharp edges look

thick and fuzzy, try changing the peaking setting. See the illustration below.

1. Level adjustment control — The Video Output Level control alters the brightness of the

displayed image. To adjust the video output level, view the display while using a small,

ﬂat-blade screwdriver to rotate this potentiometer.

If the interface receives a typical (0.7 volts p-p) analog computer video input, the output is

as follows:

Select a level setting of 0.7 volts or above to compensate for the decrease in signal level that

occurs when the signal passes through long cables. Set the level at the maximum setting

for cable lengths over 500 feet for all computer signals of 15 kHz to 135 kHz.

2. Peaking control — The Video Output Peaking control 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 optimum picture sharpness.

Operation

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

monitors, speakers). After powering up the RGB 580xi, the image should now appear on the

screen, and sound should be audible. If you are experiencing problems, please refer to the

“Troubleshooting” section of the user’s manual.
