Power LED — The two-tone Power LED lights amber or green:
• Amber when the DVI-RGB 200 is receiving power but no DVI input signal is applied.
• Green when the DVI-RGB 200 is receiving power and a DVI input is present.

Level Boost control — The Level Boost control alters the brightness of the picture on
the RGB output. Judge the adjustment visually by looking at the display.
• At the minimum level setting (the counterclockwise limit of this control), the
interface outputs video at 0.7 Vp-p.
• At the maximum level setting (the clockwise limit of this control), the interface
outputs video at 1.45 Vp-p.
Select a level setting of 0.7 V and above to compensate for the signal level decrease that
occurs with long cables. Set the level at the maximum setting for cable lengths over 500
feet.
NOTE: Level Boost has no effect on the DVI output of the Buffered Loop-through
connector.
j
Peak control — The Peak (peaking) control affects the sharpness of the picture on the
RGB output. 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 percent peaking. Adjust this control while viewing the
displayed image to obtain the optimum picture sharpness.
NOTE: Peaking has no effect on the DVI output of the Buffered Loop-through
connector.
