DESCRIPTION
The IN2080 / 2081 / 2090 are dedicated computer video interfaces designed to work with specific
computer graphic signals. Like other INLINE interfaces, the IN2080/81/90 carry out two primary
functions. The first function is signal splitting, since these interfaces allow for the simultaneous
connection and viewing of both the computer’s local monitor and a large screen data projector or monitor.
The second function is physical and electronic interfacing. The IN2080/81/90 each respectively take in a
VGA, MAC, or CGA/EGA video signal and provide an output signal in the most convenient format,
RGBS on four BNC connectors. The IN2080/81/90 dedicated computer video interfaces are fully
automatic, offering easy operation and the following features:
♦
Horizontal position control - allows picture to be centered precisely on the data display screen
♦
Loop through output for the local computer monitor
♦
Standard RGBS analog video output on four BNC connectors
♦
100 MHz bandwidth
INPUT COMPATIBILITY
The IN2080/81/90 interfaces will accept video signals with horizontal scan frequencies between 15.7
KHz and 78.0 KHz as detailed below:
IN2080 - operates with analog video input from a wide variety of IBM and compatible computer video
signal formats including VGA, SVGA, XGA, and 8514A. Input signals to the IN2080 must in the
RGBHV format and provided on a 15 pin HD connector. The IN2080 may be used with a monochrome
local monitor if an IN9030 monochrome monitor adapter is used.
IN2081 - operates with analog video input from most Apple computers including:
-- MAC II, MAC IIci, MAC IIcx, MAC IIfx, MAC IIsi, MAC IIx, MAC LC, MAC IIvx, Quadra, Centris,
Performa, and other models with similar video signals.
-- Third party video cards from manufacturers such as Raster Ops and Super Mac which use a
compatible RGBS signal on a 15 pin D output connector.
-- Other Apple computers such as the Apple IIGS and Powerbooks which feature a 15 pin D video output
connector. Please note that certain models of the Apple Powerbook do not normally provide a video
output signal and require a third party video output adapter to drive an external video display device.
IN2090 - operates with digital video input from CGA and EGA graphics cards. The IN2090 converts
digital video input signals into analog video signals. Input to the IN2090 must be digital RGB signals in
the separate Horizontal and Vertical sync format and provided on a 9 pin D connector.
OUTPUT COMPATIBILITY
The IN2080/2081/2090 output an RGBS format signal (Red, Green, Blue, and composite sync) on four
BNC connectors. The output signal is compatible with many data projectors and monitors. VGA,
MACII, CGA, and EGA type video cards operate in several different modes encompassing a wide range
of resolutions and horizontal scan rates. The IN2080/81/90 are not scan converters and the data projector
or monitor must be compatible with the horizontal scan rate put out by the computer video card. Please
check the documentation for both the computer video card and the data projection device in order to
ensure compatibility.
