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.  
If 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.

Level  
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:

Setup Guide — RGB 580xi  
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  
approximately one-half turn between the minimum and maximum level settings  
to output unity level video.  
At the maximum level setting (the clockwise limit of this control), the interface outputs  
video at 1.45 volts p-p.  
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 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.  
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.
