IN2022HR OPERATION MANUAL - REV 1.3 12/08/00 ©2000 - INLINE, INC.
Convenient Controls - offer intuitive one-touch command capability over the most important
signal adjustments.
•
Gain Control - adjusts the voltage level of the RGB components simultaneously
(ensuring that gray scale is maintained), and may be used to compensate for signal loss
due to long cable runs.
•
Sharpness Control - provides effective image enhancement for high-resolution video
signals by increasing clarity and edge detail.
•
Horizontal Position Control - allows the picture to be centered precisely on the data
display screen.
Compatibility
INPUT
The IN2022HR will accept high-resolution video signals from VGA or MAC-type video cards.
Input signal compatibility parameters are:
Video Signal: Analog RGB Video
Connector: 15-Pin HD female or 15-pin D female video output port*
Signal format: RGsB, RGBS or RGBHV
Horizontal Frequency Range: 15 KHz to 135 KHz
Vertical Refresh Rates: 30 Hz to 120 Hz
* Newer MAC G3 and G4 models (with translucent cases) have 15-pin
HD connectors (pins arranged in three rows). Older G3 models (with
solid white enclosures) incorporate 15-pin D connectors (pins arranged
in two rows).
OUTPUT
The IN2022HR outputs an analog RGsB, RGBS, RGBHV or Composite Monochrome signal on
female BNC connectors. This output signal is compatible with high-resolution data grade
monitors and data / graphics projectors.
VGA and MAC computers operate in several video modes encompassing
a wide range of resolutions and scan rates. Many of the video signals
from the newest models can run as high as 70 KHz or more, with the
newest VGA cards offering an output resolution of 1600 x 1200 (some
can even go as high as 1920 x 1080). The data projector or monitor
connected to the interface output must be compatible with the horizontal
scan rate and vertical refresh rate of the computer’s video signal.
Please check the documentation for both the computer graphics card
and the data display device to ensure compatibility.
