DESCRIPTION
The IN2022HR is a high performance, dual function, computer video interface for VGA and
MAC-type video signals. The unit features a permanently attached, dual-headed input cable,
optimized for high-resolution signals. Like other INLINE interfaces, the IN2022HR performs
the following functions:
•
•
•
Signal Splitting - allows the simultaneous connection and viewing of both the
computer’s local monitor and a second output device such as an LCD data projector or a
presentation monitor.
Physical Interfacing -The IN2022HR connects directly to VGA and MAC G3 & G4
computers with 15-pin HD video connectors, or older Macintosh family computers with
15-pin D video connectors.
Electronic Interfacing - Dipswitches located on the bottom of the interface allow users
to manually select output sync signal characteristics, or allow the unit to make the
conversions automatically.
The IN2022HR 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.

Installation
This section offers step-by-step instructions for installing the IN2022HR. An Application
Diagram is provided on the following page.
1.) Turn the Computer and Computer Monitor Off - Disconnect the monitor from the
computer’s video port.
2.) Connect the IN2022HR Input Cable - to the computer’s video output port. The input cable
is the 4’ long “Y” cable permanently attached to the interface. Connect one of the
connectors on this cable to the computer’s video port as per the instructions below:
Œ
PC Compatible Computers (VGA) and Newer MAC G3 & G4 - Connect
the 15-pin HD connector on the IN2022HR input cable to the computer
video output port (see diagram to the right). Do not connect anything to the
15-pin D input connector.
Œ
MAC Computers (older models) - Connect the 15-pin D connector on
the IN2022HR input cable to the computer video output port (see diagram
to the right). Do not connect anything to the 15-pin HD input connector.
3.) Connect the IN2022HR Video Output - (5 BNC connectors) to the data display device's
RGB input, using three, four, or five high-resolution BNC cables or a multi-conductor
RGBHV, RGBS, or RGB "snake". The IN7000 Series, IN7200 Series, IN7300 Series and
IN7400P Series high-resolution cables are well suited for this purpose. Take care while
making connections to ensure that the red output is connected to the red input, green output
to the green input, etc.
4.) Select the Output Sync Format - The interface will automatically set the output sync
format according to the number of cables connected to the output. Users can to override the
automatic output format feature and manually select a specific format by setting the
dipswitches according to the chart on page 6.
5.) Connect the Local Computer Monitor - (if present) to the appropriate Local Monitor
Output Port on the IN2022HR.
Œ
For Applications that Require a Local Monitor - make sure that all dip switches on
the bottom, right–hand side of the box labeled MONITOR EMULATION are set to “0”.
Œ
If no Local Monitor is Required - refer to the Monitor Emulation Cart on page 9.
Check the Monitor Emulation chart and dipswitch settings carefully. An
improper setting of the emulation dipswitches may lead to improper operation
and could even result in severe damage to the computer video port or the
monitor. If there is any doubt as to which monitor emulation setting is
correct, connect a local monitor and set all the Monitor Emulation
dipswitches to “0.” The interface will adjust the video output automatically.
6.) Apply A/C Power - to the IN2022HR using the IN9230 IEC power cable (included).
7.) Turn the IN2022HR, the Computer and the Computer Monitor on - If necessary, adjust
the gain, sharpness and horizontal position controls (see pages 5 & 6 for more details).

Front Panel Controls
The IN2022HR features fully automatic operation, however, the interface offers several
external controls that allow users to optimize the unit’s performance to meet the needs of
specialized applications. Gain, sharpness and horizontal position control adjustments are
located on the front of the IN2022HR. Turning the adjustments clockwise will increase the
value, and counterclockwise will decrease it.
GAIN CONTROL
The gain control is a small black knob located on the left side of the unit’s front panel. The
gain control adjusts the output voltage of the red, green, and blue outputs simultaneously
(ensuring that gray scale is maintained), and may be used to compensate for signal loss due
to long cable runs. The gain adjustment range is .7 in the minimum position (30% decrease)
and 1.3 in the maximum position (30% increase). The factory default setting is 1.0 (unity
gain).
SHARPNESS CONTROL
The IN2022HR sharpness / peaking circuitry provides variable high frequency equalization
that can compensate for high frequency losses due to long output cable runs. The amount of
high frequency boost required will vary depending on the length and bandwidth performance
of the video output cables, and, to a lesser extent, the resolution and frequency of the input
signal. When using short output cables, the sharpness control should usually be placed at the
minimum setting to avoid over-peaking.
The sharpness control is located between the gain control knob and the local monitor output
port. The factory default setting is minimum (no sharpness / peaking enhancement). The
following guidelines are useful in selecting the optimal sharpness / peaking setting:
If the image is soft and / or fine details in the picture lack clarity:
The sharpness is probably set too low. Increase the sharpness control setting.
If a white, ghosted image appears to the right side of the lines / characters:
The sharpness is probably set too high (over-peaked). Decrease the sharpness control
setting.
HORIZONTAL POSITION CONTROL
The horizontal position control is a small black knob located adjacent to the front panel
power LED display. This adjustment allows users to shift the position of the image on the
data display device from left to right. The horizontal position control does not effect the
local monitor.
If the horizontal position adjustment is set to an extreme position on either the display device
or the IN2022HR, the output image may appear dark and / or the colors may be displayed
improperly. To position the video image and achieve optimum picture quality:

1. Set the display device’s horizontal position control to the center of its adjustment
range.
2. Adjust the horizontal position control on the IN2022HR until the picture is centered
properly on the display device.
Horizontal Position Control Enable / Disable - The factory default setting is horizontal
position control enabled. In rare cases (depending on the design of the display device sync
circuitry), operators may have to disable the horizontal position control to achieve a solid
image on the display device. The horizontal position control may be enabled or disabled by
setting the appropriate switch in Dipswitch Bank #1 as indicated in the chart below.
Dipswitch Settings
Two dipswitch banks are easily accessed through windows on the bottom of the IN2022HR. Bank
#1 regulates the output sync format, and Bank #2 determines the monitor emulation settings.
DIPSWITCH BANK #1
For most installations, the IN2022HR will be operated in the factory default mode and will not
require any changes to the dipswitch settings. The factory default settings are:

OUTPUT SIGNAL FORMAT SELECTION
Automatic Sense Mode - In the factory default configuration, the IN2022HR automatically
senses the number of cables connected to the output BNC connectors and selects the
appropriate output signal format. LED indicators located next to the V/Sync, H/Comp Sync
and Green output BNCs (on the back of the interface) provide clear visual confirmation of
the current output sync format. In order for output format auto sense circuit to operate,
dipswitch 5 must be set to 1.
Manual Mode - Some applications will require the interface to operate in a specific output
format, thus requiring users to override the automatic sense mode. To set the output sync
format manually, users must first disable the auto sense circuit by setting dipswitch #5 to 0,
and then setting select dipswitches according to the table below (to set the desired output
format).

Keep in mind that PCs and MACs operate in several video modes
encompassing a wide range of resolutions and scan rates. The data
projector or monitor must be compatible with the horizontal scan and
vertical refresh rate of the computer’s video signal. Please check the
documentation for both the computer graphics card and the data display
device to ensure compatibility.
DIPSWITCH BANK 2: MONITOR EMULATION
The IN2022HR includes a bank of 10 dipswitches on the bottom of the interface for monitor
emulation. Setting the dipswitches to the appropriate positions allows the unit to emulate the
appropriate sense signals, thus setting the video card to the desired frequency, refresh rate
and resolution, even without a local monitor. When configured properly, the interface can
emulate virtually any type of monitor.

Using the IN2022HR with a Local Monitor - Many high-resolution graphic workstations
use sense signals to set resolution, horizontal frequency and vertical refresh rate. The
IN2022HR passes all sense pins between the computer video port and the Local Monitor,
ensuring that the computer can sense the attached monitor and set itself to an appropriate
resolution and scan rate for that device. The Monitor Emulation dipswitches must all be
set to “0” when using a local monitor. This allows all sense pins to pass through,
ensuring proper operation of the graphics card and monitor.
Using the IN2022HR without a Local Monitor - The IN2022HR’s design makes it easy to
use the interface without a local monitor. Because the Local Monitor Output port is
buffered, there is no need for a termination plug to terminate the video signals when used
without a local display device. If you are not using a local monitor, but need to emulate a
specific mode, locate your workstation type and desired mode in the chart on the following
page. If you are not sure of the exact mode to select for your computer, select the setting
shown in bold since it is the most common mode. Using the IN9339 Adjustment Tool
(provided), gently set the dipswitches to the appropriate settings.
Check the Monitor Emulation chart and the IN2022HR dipswitch
settings carefully. An improper setting of the emulation dipswitches
may lead to improper operation and could even result in severe
damage to the computer video port or the monitor. Some modes listed
on the following page may not be supported by certain workstations /
graphics cards.

Troubleshooting
Problem: The display device connected to the RGB output has a bad/scrambled image.
Œ
Solution 1: The display device connected to the output of the IN2022HR may not be
compatible with the computer output. Many PCs and MACs have new and ultra high-
resolution modes such as 1600 x 1200 and 1800 x 1440, and can output a video signal with a
horizontal scan rate of over 100 KHz! Many data monitors and data projectors are not
compatible with these resolutions and frequencies.
Œ
Œ
Solution 2: The output cable may have a bad sync line. Try running the sync through
another cable.
Solution 3: The IN2022HR output sync format may not be compatible with the display
device. Check the documentation for both the computer graphics card and the data display
device to ensure compatibility.
Œ
Solution 4: You may not connect both a PC and a MAC to the IN2022HR
simultaneously! Connect one or the other.
Problem: The power switch is turned on, but the front panel POWER LED is dark.
Œ
Solution 1: Make sure that the IN9230 IEC power cable is securely plugged into the unit and
the A/C source.
Œ
Œ
Solution 2: Make sure the A/C source is live.
Solution 3: The IN2022HR contains a time delay fuse. To change the fuse, disconnect the
IN9230 IEC power cable and slide out the fuse holder (located on the rear panel to the left of
the IEC cable receptacle) using the IN9339 INLINE adjustment tool.
Problem: The output image is very dark.
Œ
Solution: The horizontal position control may be set to an extreme position or may be
interacting poorly with the horizontal position control on the display device. Follow the
horizontal position adjustment procedure on page 5.
Problem: The output image is missing a color.
Œ
Solution: The output RGB cable may be bad. Try switching connections on the output to
verify that the bad color’s 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.)
Problem: The MAC connected to the IN2022HR is not booting up in the right resolution mode.
Œ
Solution: The monitor emulation dipswitches on the bottom of the IN2022HR are
probably forcing the computer into the wrong mode. When using a local monitor, set all
monitor emulation dipswitches to 0.

IN2022HR OPERATION MANUAL - REV 1.3 12/08/00
12
Problem: A laptop is connected to the IN2022HR input. The display device connected to the
IN2022HR main output (5 BNCs) is not showing an image.
Œ
Solution 1: All monitor emulation dipswitches must be set and all connections must be
made before powering up the laptop. This tells the laptop to make the video port active.
Solution 2: The laptop’s video port may require a keystroke to make the video port active.
Many laptops have a key with a monitor shaped icon that activates the external video port.
With many laptops, each time you press the monitor key, the video will cycle between the
three possible video modes: Laptop display screen active / external video port active / Laptop
display screen and external video port active.
