Front Panel Controls
The IN2013HR features fully automatic operation, however, the interface offers several external
controls that allow users to optimize the unit’s performance to meet the needs of specialized
applications. Gain, sharpness and horizontal position control adjustments are located on the
front of the IN2013HR. Turning the adjustments clockwise will increase the value, and
counterclockwise will decrease it. Each control has an adjustment range of 15 turns.
GAIN CONTROL
The gain control is a small black knob located on the left side of the unit’s front panel. The gain
control adjusts the output voltage of the red, green, and blue outputs simultaneously (ensuring
that gray scale is maintained), and may be used to compensate for signal loss due to long cable
runs. The gain adjustment range is .7 in the minimum position (30% decrease) and 1.3 in the
maximum position (30% increase). The factory default setting is 1.0 (unity gain).
SHARPNESS CONTROL
The IN2013HR sharpness / peaking circuitry provides variable high frequency equalization that
can compensate for high frequency losses due to long output cable runs. The amount of high
frequency boost required will vary depending on the length and bandwidth performance of the
video output cables, and, to a lesser extent, the resolution and frequency of the input signal.
When using short output cables, the sharpness control should usually be placed at the minimum
setting to avoid over-peaking.
The sharpness control is located between the gain control knob and the local monitor output port.
Using the IN9339 Alignment Tool (included), turn the sharpness control clockwise to increase
the sharpness setting, and counterclockwise to decrease the sharpness setting. The factory
default setting is minimum (no sharpness / peaking enhancement). The following guidelines are
useful in selecting the optimal sharpness / peaking setting:
If the image is soft and / or fine details in the picture lack clarity:
The sharpness is probably set too low. Increase the sharpness control setting.
If a white, ghosted image appears to the right side of the lines / characters:
The sharpness is probably set too high (over-peaked). Decrease the sharpness control
setting.
HORIZONTAL POSITION CONTROL
The horizontal position control is a small black knob located adjacent to the front panel power
LED display. This adjustment allows users to shift the position of the image on the data display
device from left to right. The horizontal position control does not effect the local monitor.
If the horizontal position adjustment is set to an extreme position on either the display device or
the IN2013HR, the output image may appear dark and / or the colors may be displayed
improperly. To position the video image and achieve optimum picture quality:
1. Set the display device’s horizontal position control to the center of its adjustment range.
2. Adjust the horizontal position control on the IN2013HR until the picture is centered
properly on the display device.
