1. Introduction to MagniLink Vision Split
MagniLink Vision Split is a video magnifier, which makes it possible to
switch and split the image displayed on the screen between the output
from a reading camera, a distance camera and a computer. MagniLink
Vision Split is available in several different models.
Choose a model via the following steps:
• Reading camera
Choose between the systems MagniLink Vision, MagniLink Pro or
MagniLink S.
• Monitor size
Choose between an 18.5” or 23” TFT screen, both available in
either integrated or free-standing versions. It is also possible to use
a monitor of your own.
If the system comes with a screen, you will also need to acquire a
monitor arm or base which complies with the standard VESA
100x100 mm.
• Reading table
Choose whether or not the system includes a reading table.
• Distance camera (if you want a two camera system)
Choose between a system with a distance camera (ML Vision Split
Student) or without a distance camera (ML Vision Split). There are
two different cameras to choose from, Standard Definition (SD)
and High Definition (HD).
• Mounting of the distance camera
You can select the type of mount to be used with the distance
camera. Choose between a table-top stand and a wall/ceiling
bracket.

5.3 Description of features
The active camera image is highlighted with an orange frame. A basic tip
for operating cameras, when more than one camera is connected, is that
the camera whose image is on-screen is automatically the one which can
be operated using the control box's camera section. (Selecting which
camera to operate is only necessary when two cameras are used
simultaneously).
1. LED
A green light indicates that the system is on. A flashing green light
means that the system is starting up. A slowly flashing yellow light
indicates standby. A red light indicates that something is wrong in
the system (see the chapter “Troubleshooting”).
2. Power on/off
Press to start or shut down the system.
3. Lighting configuration
By pressing these buttons it is possible to adjust the brightness.
Press up to increase and down to decrease the brightness. When
the picture mode button (7) is pressed, the lamp’s intensity is
adjusted instead. In this way, the best conditions for reading in
different situations can be achieved.
4. Autofocus on/off
Press the button once to lock the focus. This can be used when you
want to write by hand. In this way, autofocus is not affected by the
pen or your hand. Press the button a second time to reactivate
autofocus. Autofocus is active whenever the system starts.
5. Magnification control
These two buttons are used to set the magnification. Reduce the
magnification by pressing the lower key (minus) and increase the
magnification by pressing the upper key (plus).

User Guide 79 45 816a | MagniLink Vision Split 15
6. Reference line/bar
Adjust the position of the reference line. Press the right-hand
button to move the horizontal line down. Hold the button in to
change the reference line to vertical and move it to the left. The
reference line then becomes a horizontal bar which diminishes the
viewing area. To make the bar vertical, press the button again. The
left-hand, sunken section of the controls has the opposite effect.
(Using the EUC software, you can adjust the colour and thickness of the
reference line and choose to hide or show the bar or reference line. Please
contact your local retailer for more information. )
7. Picture mode
Press the button to toggle the picture mode between natural
colours and grey scale.
Lighting adjustment
Hold the button down to temporarily enable adjustment of the
lighting via the lighting configuration (3). This can be used to help
users who are sensitive to light, or when reading on blank paper.
The system automatically switches between ROPC (Reading
Optimized Picture Control) and DPC (Dynamic Picture Control)
when the lighting reaches a certain level. When the lighting
configuration (3) is used to adjust the lighting, it is not possible to
switch between colour and grey scale.
Lights off/on
The lights can be switched on and off by holding the button down
for three seconds. The system switches automatically between
ROPC (Reading Optimized Picture Control) and DPC (Dynamic
Picture Control).
(The light settings can be locked and grey scale removed using the EUC
software. Please contact your local retailer for more information.)

16 User Guide 79 45 816a | MagniLink Vision Split
8. High contrast modes with artificial colours
Press the key to toggle between the various colour combinations.
The following colours are in the default configuration:
Background/Text
White/Black
Black/White
Yellow/Black
Black/Yellow
Green/Black

Background/Text
Red/Black
Black/Red
Yellow/Blue
Blue/Yellow
White/Blue
Blue/White
(The colour setting in high contrast mode can be adjusted using the EUC
software. Please contact your local retailer if you have any questions.)
9. Full screen/split screen
Using this button, you can quickly change between the current split
screen mode and full screen. The image displayed in full screen
mode depends on the mode that the image splitting sources (12) are
set to. If the desired mode is not active, press this button.
10. Split screen adjustment
Adjust the positions and sizes of the split screen sections. Select
horizontal or vertical split screen with button 11.
11. Horizontal/vertical split screen
Switch between horizontal and vertical split screen by briefly
pressing this button.
12. Image splitting sources
If three image sources are connected, this button switches
between the four different split screen modes. If two or fewer
image sources are connected then this button has no effect.
1. Reading camera/computer
2. Distance camera/computer
3. Reading camera/distance camera
4. Reading camera/distance camera/computer
13. Camera selection
This button is used to select which camera you wish to operate.
The active camera image is highlighted with an orange frame. This
button has no effect if only one camera is connected.

User Guide 79 45 816a | MagniLink Vision Split 17
14. Programmed magnification (and direction for distance
cameras)
The three buttons marked (I), (II) and (III) are used to quickly select pre-
programmed settings for a given space and/or camera magnification.
The distance camera can be programmed with the desired
magnification to quickly point to three different locations in the room.
The reading camera can be programmed with the desired
magnifications and selection of artificial colours.
Point the distance camera at the desired location in the room and
adjust the magnification. Hold down one of the buttons marked (I),
(II) or (III) for three seconds to save the position. The orange frame
briefly turns thicker to indicate that the position has been saved.
The programmed modes can now be selected by briefly pressing
one of the three buttons.
15. Operating the distance camera
These buttons are used to adjust the distance camera horizontally
and vertically. The camera can be adjusted both horizontally and
vertically at the same time. The speed is automatically adjusted
and is dependent on the level of magnification.
(The limits and speeds of the pan and tilt can be adjusted using the EUC
software. Please contact your local retailer if you have any questions.)

18 User Guide 79 45 816a | MagniLink Vision Split
Foot pedal
Using the foot pedal, you can quickly change between the current split
screen mode and full screen without having to touch the control box.
The foot pedal has the same function as button 9.

6. Troubleshooting
• If the indicator lights on the control box (in/out indication) do not
light up at all when pressing the button, check that the power cable is
correctly connected and that there is a current coming from the wall
socket.
• If no picture signal is being received from the computer, check that
the computer is on and that its video cable is correctly connected at
both ends. It is important that the video resolution is set correctly
(see below) and that the refresh rate of the selected video mode is
set to 60Hz.
• If no picture signal is received from either the computer or the
reading camera, check that the monitor is on and that its cables are
correctly connected.
• If a weak picture is received from the reading camera, check that the
light is on.
In the event of any problems with the unit, try resetting the system by pulling out
the power cable. Wait at least 30 seconds before plugging the power cable back
in and restarting the system.
Contact a service technician if the above measures do not help or if other
errors have occurred. Never remove any panels in order to attempt to repair
the system yourself.

20 User Guide 79 45 816a | MagniLink Vision Split
If the split screen does not work with the computer
MagniLink Split is compatible with refresh rates of up to 60 Hz and most
screen resolutions of up to 1920x1080 pixels from a connected
computer.
On occasions, you may notice that, when changing video mode on the
computer or when first starting up following a change of video mode, only
the computer image is shown on the screen (non-shareable window) when
you attempt to start up the system. This can be due to the computer being
in hibernation mode, or the screen being in energy saving mode, which
means you need to move the mouse in order to get the screen to function
in split screen mode again.
If this does not work, try changing to a different video mode on the
computer.
