Front Panel Adjustments

Video signals passing through long cable runs (over 125 feet) 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 one-turn potentiometer. You can judge the adjustment visually by looking at the display.

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

0.5volts 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

1.45volts 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.

Extron’s various RGB 580xi AAP double-space devices may be mounted to any Extron product that has an AAP faceplate, or to an Extron AAP wallplate. See appendix A for AAP device part numbers. The AAP device should be cabled before it is attached to a faceplate or wallplate (see “Cabling the AAP Device Rear Connectors” in this chapter). The screws needed for installing an AAP device are built into its front panel, so no additional screws are needed.

1.Insert the AAP’s screws through the holes in the AAP faceplate or the AAP wallplate. Secure the AAP device to the faceplate or wallplate with the provided captive washers and #4-40 nuts.
