Compatibility – Extron Electronics IN2118 User Manual

Page 5

The IN2118 Interface is not a scan converter. The data projector, monitor
or other output device must be compatible with the horizontal scan rate,
vertical scan rate and resolution output by the computer video card.

Compatibility

INPUT

The IN2118 Interface will accept high-resolution video signals from virtually any computer that
outputs an analog video signal. The unit will work with signals at virtually any resolution and
refresh rate. Compatible computer video signals include VGA, SVGA, XGA, MAC, SUN, SGI
and other high-resolution computers outputting an analog video signal. Input signal compatibility
parameters are listed below.

Video Signal:

Analog RGB Video

Signal

Format:

RGBHV,

RGBS,

RGsB*

Horizontal Frequency Range:

30 KHz to 130 KHz

Vertical Refresh Rates:

30 Hz to 120 Hz

* The IN2118 Interface will operate with RGsB input signals. However,
the unit will not strip sync off of the green. RGsB input signals are always
output as RGsB (they cannot be output as RGBS or RGBHV). Also, the
horizontal position control will not operate when used with RGsB input
signals.

OUTPUT

The output signal of the IN2118 Interface is analog RGB video with TTL sync on 3, 4 or 5
female BNC connectors. The output format can be set to RGBHV, RGBS or RGsB using
dipswitches. This output signal is compatible with high-resolution data grade monitors and data /
graphics projectors.

VGA, MAC, SUN, SGI and other high-resolution workstations 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 resolu-
tion of 1600 x 1200 (some can even go as high as 1000 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. Check the documentation for both the computer graphics
card and the data display device to ensure compatibility.
