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.

IN2000 AND IN2001 DIFFERENCES

These two interfaces are virtually identical in function, features, and operation with only a few minor differences as detailed in the chart below:

IN2000 IN2001

Power Supply: External Power Adapter Internal Power Supply

Size: 1.1" H x 4.8" W x 3.27" D 2" H x 6.75" W x 4.33" D

Adjustment Pots: Top mounted, hand adjustable Recessed pots, adjustable with

tweeker tool

Dip Switches: Internal Externally Accessible

INPUT COMPATIBILITY

The IN2000 / IN2001 universal interfaces will accept video signals with horizontal scan frequencies between 15.7 KHz and 145.0 KHz. In order to interface to different computers, the appropriate IN5100 Series Monitor Loop Cable must be used. For more information and a complete listing of IN5100 Monitor Loop Cables, see Pages 3 & 11. Common analog, TTL, and ECL signals are listed below along with compatible signal formats.

MAC/MAC+, MAC SE, IBM 3400 Series.

sync signal w 1, 2, 3, 4 or 6 bit TTL video with separate H & V sync signals

w 1 or 3 bit ECL video with separate H & V syncs

While the input connector on the IN2000/2001 looks like a standard 15 pin HD VGA connector (15 pins in three rows), this input uses proprietary pin connections to accommodate the unit’s universal design. VGA and other signals can not be attached directly to the input without the appropriate IN5100 Series loop cable.

OUTPUT COMPATIBILITY

The IN2000 / IN2001 output an analog video signal in the RGBS format (Red, Green, Blue, and composite sync) on four BNC connectors. The output signal is compatible with many data projectors and monitors. In addition to the default RGBS output format, the IN2000 / IN2001 may be set to output RGsB or Composite Monochrome Video with Sync by changing the dip switch settings (see Pages 8 &

9).

A special version of the IN2000 is available for installations requiring an RGBHV output. This unit features a 15 Pin HD Female connector on the output and may be ordered using the following model designation: IN2000SP RES911722.

VGA, MACII, and high resolution workstation video cards operate in several different modes encompassing a wide range of resolutions and horizontal scan rates. The IN2000 and IN2001 are not scan converters and the data projector or monitor must be compatible with the horizontal scan rate output 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.

IN5100 SERIES MONITOR LOOP CABLES

Unlike Dedicated Video Interfaces which are designed to work with one specific type of computer graphic signal and feature a permanently attached input cable, Universal Interfaces such as the IN2000 / IN2001 function with a wide variety of input signals. These interfaces derive a great deal of their flexibility and "universality" through the use of detachable input cables. The IN5100 Series includes dozens of special input cables, each designed for a specific type of computer graphic signal or computer model. For example, the IN5101A is designed for VGA / S-VGA / XGA type signals, while the

IN5161A works with MACII type video signals. Four main characteristics determine the make up of an IN5100 Series cable:

w Analog or Digital signal

w Sync Format (RGBS, RGBHV, RGsB / RsGsBs, Monochrome) w Video Output Connector Type (15 pin HD, 15 pin D, 25 Pin D, etc.) and pin-outs w External or Internal Installation

Analog or Digital

Analog Cables are designated with the letter "A" (IN5101A, IN5133A, IN5161A). ECL cables also receive the "A" designation (IN5126A, IN5137A ). TTL Digital Cables are designated with the letter "T" (IN5106T, IN5122T, IN5158T).

External or Internal Cables

Most IN5100 Series cables are inserted in-line between the computer’s video output and the monitor input cable (see diagram on page 5). Some computers and terminals do not offer an external video output, and INLINE has designed special internal IN5100 Series cables for several of these models. Each internally mounted IN5100 Series cable includes an instruction sheet describing the installation procedure.

A partial listing of the most popular IN5100 Series Monitor Loop Cables is located on Page 11.

INSTALLATION

This section offers step-by-step instructions for installing the IN2000 / IN2001. A detailed application drawing showing all equipment connections is included on the next page.

1. Turn the computer and computer monitor off. Disconnect the computer monitor (if present) from the video output port on the computer.

2. The IN5100 Series cables have a pass-through connector (Male and Female) on one end. The pass- through end is connected to the computer and local monitor. Connect the male side of the pass- through connector to the computer’s video output port.

3. Connect the local computer monitor (if present) to the female side of the IN51XX pass-through. If no local monitor is used, a termination plug is required for analog type video signals.

It is very important that the female side of loop-through cables receive a 75 ohm signal termination when interfacing analog video signals. If no termination is provided, the output of the interface will be very overdriven, appearing very bright with poor contrast. The termination is also required by certain video cards (VGA, newer MACII, etc.) because they sense the attached monitor at boot up and set the card for the appropriate mode.

Two of the most popular termination plugs are listed below:

IN5101A Cable Use an IN9031 15-pin HD VGA terminator plug (not included).

This emulates a color VGA monitor.

IN5161A Cable Use an IN9056 15-pin D MAC II terminator plug (not included).

This emulates a 13"/14" Apple monitor.

4. Connect the other end of the IN51XX cable (single male 15 pin HD connector) to the input connector on the IN2000 / IN2001.

The IN2000 / IN2001 must be located immediately adjacent to the computer. Do not attempt to lengthen the IN51XX loop-through cable. If the IN51XX cable is extended, ghosting or other signal problems may occur. Also, the local monitor cable should not be more than 6 - 12’ long.

5. Connect the IN2000 / IN2001 RGBS output (4 BNC connectors) to the data display device’s RGBS input, using four high resolution BNC cables or a multi-conductor RGBS "snake". The IN7000, IN7100, and IN7600 series high resolution cables are well suited for this purpose. Take care while making connections to insure that the red output is connected to the red input, green output to the green input, etc.

6. Apply power to the interface. The green power LED will light to indicate the unit is receiving power.

IN2000: Use the 12V 500 mA included power supply.

IN2001: Use a standard power cable (included on U.S. units).

7. Complete the installation by turning the computer and computer monitor on. If required, adjust the horizontal position and RGB gain controls as detailed on Pages 6 and 7.
