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  
computers 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  
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.

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 units universal design. VGA and other signals can not be  
attached directly to the input without the appropriate IN5100 Series loop cable.  
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 &  
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.  
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:  
Analog or Digital signal  
Sync Format (RGBS, RGBHV, RGsB / RsGsBs, Monochrome)  
Video Output Connector Type (15 pin HD, 15 pin D, 25 Pin D, etc.) and pin-outs  
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 computers 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

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 computers 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  
IN5161A Cable  
Use an IN9031 15-pin HD VGA terminator plug (not included).  
This emulates a color VGA monitor.  
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 - 12long.  
5. Connect the IN2000 / IN2001 RGBS output (4 BNC connectors) to the data display devices 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  
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.

The location of the horizontal position control is diagrammed on the next page. The horizontal position  
control adjusts the position of the image on the data display device from left to right (it has no effect on  
the local computer monitor). This control adjusts through a range of 14 full knob rotations, offering very  
fine control over the image position. The pot emits a soft click if either extreme position is reached.  
Many data projectors and monitors have their own horizontal position control, and the interaction of the  
display devices horizontal control and the interfaces horizontal control may result in a dark image on the  
data display. The following procedure is suggested to ensure best results:  
1. Adjust the IN2000 / IN2001 horizontal position control so a good quality image is displayed. This  
control should not be set to an extreme position.  
2. Adjust the display device horizontal position control until the image is centered as desired.  
3. If the image appears dark or the colors are not properly displayed, fine tune the controls on both the  
display device and the interface until the picture is centered and a good quality image is attained.  
The RGB gain control locations are shown in the diagrams on the next page. The factory setting is unity  
gain, meaning that a 1.0 volt Red, Green, or Blue input signal will appear at the IN2000 / IN2001 outputs  
as a 1.0 volt signal. These controls may be adjusted if required to calibrate the color balance between the  
red, green, and blue signals.  
The RED, GREEN, and BLUE Gain controls provide a gain  
adjustment range from 0.8 in the extreme clockwise position to  
1.2 in the extreme counterclockwise position. The gain pots  
may be adjusted by hand or using the small tweeker tool  
supplied. The entire rotation range for the gain pots is just over 180 degrees from stop to stop, so care  
must be taken not to force or over-rotate the pots.  
The IN2000 / IN2001 include a BLUE CONTROL (location shown on the next page) which may be used  
to enhance the visibility of computer graphic displays containing a lot of blue (blue text, blue graphics, or  
a blue background). This control affects only TTL digital input signals and works by adding various  
amounts of green into the blue portions of the projected image. This results in an aqua color which is  
generally more detailed and sharper, especially on older video projectors which often have a fairly soft  
focus on the blue CRT.  
The default for the BLUE CONTROL is no blue enhancement (most accurate color) and corresponds to  
the control in the extreme counterclockwise position (about 8 oclock). Full blue enhancement occurs at  
the extreme clockwise position (about 4 oclock). The BLUE CONTROL pot may be adjusted by hand or  
using the small tweeker tool supplied. The entire rotation range for the BLUE CONTROL is just over  
180 degrees from stop to stop, so care must be taken not to force or over-rotate the pot.

The IN2000 and IN2001 have been designed with several controls which may be used by qualified  
technicians to adjust specialized signal parameters. These controls, consisting of 10 dip switches and one  
adjustment pot, are infrequently used and do not require adjustment for normal daily operation. For  
convenience, the IN2001 has been designed with two access slots in the bottom of the unit so the case  
does not need to be opened to change the dip switches and adjustment pot. To access these controls on  
the IN2000 follow the procedure listed below.  
CAUTION: Any adjustment of internal controls on the IN2000 must only be carried out by qualified  
technicians. The interface case must be opened to adjust these controls and extreme care must be  
taken to avoid static shock to the internal components and/or damage to the pins which connect the  
top and bottom circuit boards.  
The following procedure may be used to access the IN2000 internal controls.  
Remove power from the IN2000.  
Remove the screw on the bottom of the unit and lift the top cover off. The top cover must be  
lifted straight up, remaining absolutely parallel to the bottom half of the interface in order to  
avoid bending the pins on the pin blocks.  
Locate the desired dip switches or control pot and gently adjust as required using a small plastic  
"tweeker" tool. See Pages 9 & 10 for details on these controls.  
Replace the top cover. The interface end panels fit into slots in the top case and will act as a  
guide, insuring that the pins and sockets on the top and bottom boards line up properly. Once the  
two halves have been rejoined, tighten the case screw.  
The drawing below diagrams the positions of the dip switches and internal control pot on the IN2000.

Horizontal Blanking Control (TTL Only)  
The Horizontal Blanking Control functions only with TTL digital input signals. This control (location  
shown on Page 8) will not need to be adjusted on a regular basis. The following image symptoms may  
indicate that the control is misadjusted: missing background colors, horizontal dark bars across the  
screen, or missing foreground colors. Before adjusting the Horizontal Blanking Control, first check to  
make sure that the external Horizontal Position Control (Page 6) is not causing any image problems. The  
following procedure is recommended for adjusting the Horizontal Blanking Control:  
IN2000 - Disconnect power and open the case.  
IN2001 - Leave power on during adjustment. Turn unit over to access the dip switches  
and Horizontal Blanking Control pot located on the bottom of the unit.  
Activate the Blanking Control Pot by turning Dip Switch #10 to ON.  
Adjust the control pot until the image quality improves and all the left hand edge of the  
screen is displayed properly without being cut off.  
Most installations will not require any changes to the dip switch settings, and the IN2000 / IN2001 will  
generally be operated with the factory default settings. The Factory Default setting and specialized dip  
switch settings are indicated below.

Turning Dip Switch #6 to ON disables the Horizontal Position Control. This setting should only be used  
with Composite Sync or Sync on Green input signals. If Switch #6 is set to ON when using input signals  
with separate Horizontal and Vertical syncs, the unit will not output any sync signal, causing the video  
projector or data monitor attached to the IN2000 / IN2001 output to loose sync and stop displaying an

The IN5129A, IN5132A, and IN5133A are special input cables designed for use with workstations and  
terminals which have BNC video outputs. The chart below describes the input signal compatibility for  
each of these cables:  
Cable / Description  
IN5129A 4 - BNCs  
IN5132A 1 - BNC  
IN5133A 5 - BNCs  
Installation Procedure - IN5129A / IN5133A  
The video signal input to the IN2000 / IN2001 must be terminated into 75 ohms for proper image  
display. In order to achieve this termination the following installation procedure should be followed:  
1. Attach a BNC "T" (1 male, 2 female) to each BNC  
output connector on the computer.  
2. Connect the IN5129A or IN5133A cable to one  
side of the "T" connectors.  
3. Connect the local monitor to the other side of the "T"  
connectors. If no local monitor is present, use a 75 ohm  
Male BNC termination plug on the Red, Green, and  
Blue connectors (TTL sync signals do not require a 75  
Ohm terminator).  
Installation Procedure - IN5132A  
The IN5132A should be connected directly to the computers monochrome composite video output. This  
cable includes an internal 75 ohm termination so the signal should not be split off to a local monitor  
before feeding it into the IN5132A or a double termination will result. If a local monitor is required, use  
one of the following methods to split the signal:  
Looping Method - If the local monitor has a "Loop Out" connector, connect the monitor  
directly to the computer video output. Turn the Loop Out termination switch to "75 ohm  
termination OFF" and connect the IN5132A to the monitors Loop Out connector.  
Distribution Amplifier - use a high resolution distribution amplifier such as the IN2055 to  
split the signal between the local monitor and the IN5132A / IN2000.

Solution 2: The display device connected to the output of the interface may not be compatible with the  
computer output. CGA and EGA signals vary from 15.75 to 24 KHz. VGA runs at  
31.5 KHz, but SVGA can be as high as 48 - 58 KHz with newer modes such as 1600 x 1200  
running at 79 KHz! MACII/Quadra computers sense which monitor is connected and  
configure themselves accordingly, with horizontal scan rates ranging from 24.48 to 68.9  
Solution 3: Check the dip switch settings to make sure the unit is putting out a sync format that the  
display device can use. For most applications the default dip switch settings (see Page 9)  
will work best.  
Solution 4: The RGBS cable may have a bad sync line. Try running the sync through another cable.  
The output image is very dark.  
Solution: The horizontal position control may be set off to an extreme position or may be interacting  
poorly with the horizontal position control on the display device. Follow the horizontal  
position adjustment procedure listed on Page 6.  
The output image is missing a color.  
Solution: Possibly the RGBS cable is bad. Try switching connections on the output to verify that the  
bad colors cable is OK (Example: If there is no red, try running the green output through  
the red cable and see if green is displayed or not.)

The output image is very bright and overdriven looking with poor contrast.  
Solution 1: The loop through cable is probably being used without a local monitor and the signal is  
therefore unterminated. Use either a local monitor or a termination plug at the monitor loop-  
through connector on the IN5100 Series cable. If this is not the problem try #2.  
Solution 2: Verify the gain settings on the IN2000 / IN2001 RGB gain pots. If they are set to a very  
high gain level, reduce the gain as required.  
Solution 3: Check the contrast and brightness settings on the display device. Many CRT type display  
devices look best with the contrast set toward the upper end of the adjustment range (75 -  
95%) and the brightness set towards the middle of the adjustment range (40 - 60%).  
The output image is ghosting.  
Solution: The IN5100 Series cables are designed to plug directly into the computers graphic card and  
a short (6 to 12 ft) monitor cable attached to the loop through output. An extension cable on  
the input or a very long monitor cable may cause this problem. Do not attempt to extend the  
length of the IN5100 Series monitor loop cable.  
When using the IN2000 and an IN5101A with a VGA signal, the image from the RGBS  
output is violet with a very low green signal.  
Solution: The local monitor may be monochrome. If it is a monochrome monitor, the IN9030 mono  
adapter must be used - the output of the IN2000 will be monochrome.  
The output image from the IN2000/2001 has horizontal black bars throughout the image  
when interfacing to TTL video signals (IN5100 cables ending with "T").  
Solution: The Horizontal Blanking Control may need adjustment. First check the Horizontal Position  
Control to ensure it is not causing the problem. If the problem persists, adjust the Horizontal  
Blanking Control according to the procedure on Pages 8 & 9.  
The output image is too green.  
Solution 1: The dip switches may be set for Sync on Green output. Try changing the dip switches to  
factory default settings (see Page 9) so the unit outputs an RGBS signal.  
Solution 2: Some MACII and Quadra computers output an RGsBS signal. If an IN5161A cable is used  
with the IN2000 / IN2001, the interface does not strip the sync off of the green, and the  
resulting output signal is actually RGsBS. The problem can be solved by disconnecting the  
composite sync signal from the display device, forcing the display to operate in Sync on  
Green mode. If the display absolutely must have an RGBS signal, then an IN5104A cable  
should be used. The IN5104A will force the IN2000 to strip the sync off of the green and  
output a true RGBS signal.  
The output image is doubled, with two images displayed side-by-side.  
Solution: The display device may not be compatible with the horizontal scan rate of the computer.  
This problem often occurs when a 31.5 KHz VGA signal is sent into an RGB monitor which  
is only compatible with signals at 15.75 KHz.
