Figure 2-6 — DVI-RGB 150 front panel

h Power LED — The two-tone Power LED lights yellow or green:

Yellow when the DVI-RGB 150 is receiving power but no DVI input signal is applied.

Green when the DVI-RGB 150 is receiving power and a DVI input is present.

i 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 0.5 Vp-p.

•At the control’s midpoint, the interface outputs video at 0.7 Vp-p (unity level).

•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.

NLevel Boost has no affect on the DVI output of the Buffered Loop-through connector.

j Peak(ing) control — The 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% peaking. Adjust this control while viewing the displayed image to obtain the optimum picture sharpness.

NPeaking has no affect on the DVI output of the Buffered Loop-through connector.

Operation

After the DVI-RGB 150 and its connected devices are powered up, the system is fully operational. If any problems are encountered, verify that the cables are routed and connected properly.

NHigh-bandwidth Digital Content Protection (HDCP) is an encryption method that protects copyrighted digital entertainment material that uses DVI video.

The DVI-RGB 150 cannot respond to the HDCP decryption key.

When the DVI input is HDCP encrypted, the

DVI-RGB 150's RGB output is blank.

NThe computer reads the DDC on power up to determine the direct digital video resolution and refresh rate to output. Ensure that the local DVI monitor and the RGBHV monitor can both display the selected resolution and refresh rate, otherwise images may be distorted or missing.

NEnsure that the computer and local monitor are connected to the DVI-RGB 150, and the DVI-RGB 150 and local monitor have power applied, before applying power to the computer. If the other devices are not turned on before the computer is, the image will not appear.
