DESCRIPTION
The IN2000 and IN2001 are universal computer video interfaces designed to work with Analog, TTL,
and ECL computer video signals. Like other INLINE interfaces, the IN2000 / IN2001 carry out three
primary functions:
Signal Splitting - these interfaces allow for the simultaneous connection and viewing of both the
computer’s local monitor and a second output device such as a large screen data projector,
monitor, or color printer.
Electronic Interfacing - Computer video output signals come in three main varieties: Analog,
TTL Digital, and ECL Digital. Several different signal sync formats are used including RGBS
(composite sync), RGBHV (separate horizontal and vertical sync signals), RGsB (sync on the
Green video signal), and Monochrome with Composite Sync. The IN2000/2001 will accept any
of these signal types and formats, outputting the signal in the standard RGBS Analog video
format.
Physical Interfacing - Computers employ many different types of video output connectors,
making it difficult to hook up computers directly to data projection devices. The IN2000 /
IN2001 simplify interfacing, routing, and switching tasks by acting as universal adapters.
Through the use of IN5100 Series removable monitor loop input cables, the IN2000 / IN2001
can be attached to virtually any computer and will provide a video output signal on four BNC
connectors which can easily be connected to an RGB display device.
The IN2000 / IN2001 are not scan converters. The data projector, monitor, or other
output device must be compatible with the horizontal scan rate output by the
computer video card.
The IN2000 / IN2001 Universal computer video interfaces are fully automatic, offering easy operation
and the following features:
♦ 100 MHz Bandwidth - High performance interface design ensures that video signals will be
interfaced with no loss of image detail.
♦ Universal Design - units will operate Analog Video, TTL Digital Video, and ECL Digital Video
input. TTL and ECL digital signals are converted to analog video, allowing output signals to be run
over long distances on high resolution coaxial cables.
♦ IN5100 Series Monitor Loop Cables - dozens of specialized input cables are available which allow
the IN2000 / IN2001 to be attached to over 95% of the computers on the market (IN5100 Series
input cables are not included with the IN2000 / IN2001, but are required for operation). This design
prevents obsolescence - users may buy the universal interface and IN5100 cable(s) they need today
and add additional cables in the future as their needs change.
♦ Loop-Through Output - provides a passive output signal for the local computer monitor.
♦ Flexible Output Signal Formats - RGBS (standard), RGsB, and Composite Monochrome.
♦ Horizontal Position Control - allows picture to be centered precisely on the data display screen.
♦ RGB Gain Controls - Red, Green, and Blue levels can be calibrated and output gain boosted to
compensate for long cable runs (up to 100’ depending on signal horizontal scan frequency).
♦ Blue Enhancement - improves visibility of digital input signals which contain a lot of blue elements.
