Introduction to the VideoMate
VideoMate Slide-to-Video Systems
Today’s sophisticated audiences expect high quality
visual aids in the presentations they attend. Since a
picture is “worth a thousand words,” as they say, there is
no better way to increase the effectiveness of a presen-
tation than to pack it full of interesting visual images.
A Navitar VideoMate is an ideal presentation tool. It
enables you to easily integrate 35mm slides into presen-
tations by converting them into video images which can
be projected through a video projector or viewed on a TV
monitor. VideoMates produce high-resolution images
with outstanding contrast and vivid color rendition, so
slides can be shown as large projected video images
without losing clarity or legibility. VideoMates are ideal
for use in boardrooms, auditoriums and training rooms,
or for AV rental and video production.
Description of the VideoMate 2250/2250P
TheVideoMate2250(NTSC)and2250P(PAL)aread-
vancedslide-to-videotransfer systems that makethe
digital connection with built-in microprocessor control.
Withthe VideoMate 2250,RS-232 control enablesthe
projector, lens and camera functions of the slide-to-video
transfer unit to be electronically controlled from a PC
computer or boardroom control system. A software
package for a PC computer is available from Navitar.
This model is equipped with genlock
The VideoMate 2250 is based on a state-of-the-art
Kodak Ektapro electronic slide projector. Integrated
inside is a high-resolution CCD camera featuring
Navitar’s acclaimed precision zoom optics. To increase
on-screen resolution even further, the VideoMate 2250
can be used with a scan doubler.
The “random access” feature of the 2250 allows the user
to choose between pre-programming the exact slide
sequence or randomly jumping to various slide tray
positions. Random access is controlled by simply
punching the slide numbers into the control system and
pressing enter.

Introduction to the VideoMate
The built-in motorized zoom lens allows the 2250 to
zoom in on slides for increased magnification or zoom
out to view entire vertical slides.
A unique “stand-by” mode, allows the projector to be
powered off and back on again without the normal return
of the slide tray to the first slide position.

Safety Precautions
Safety Precautions
To prevent damage to the equipment and operating
personnel, please observe the following precautions:
Set the projector voltage switch to the proper wall outlet
voltage for your country (USA = 120v and UK = 240v).
Make sure that the voltage source contains a satisfactory
path to ground.
Do not operate the unit where fluids can come into
contact with the electrical components.
Maintain a six-inch air space around all sides of the
equipment to allow for proper ventilation.
When changing the bulb:
1. Disconnect the electrical supply.
2. Allow the unit to cool.
3. Use only a General Electric 787 (6 volt, 10 watt) lamp
ortheequivalent(Navitarpart#9-12126). Higher
wattagelampswill cause severe internalDamageto
thecamera and electronics.
There are no user serviceable components (other than
changing the lamp). Opening the unit will expose danger-
ous voltage levels and sensitive electronic components.
A qualified technician should perform all repairs.
To prevent the unit from damaging condensation and
thermal shock, certain procedures must be followed:
1. In cold weather, always put the unit in a moisture proof
containeror enclosure before transporting.
2. Either keep the unit warm during transportation, or
allow sufficient time for it to warm up at the destination.
Keepthe unit inthe original moistureproof package
while it warms up. (The goal is to prevent warm, moist
air from striking the cold electronic and optical compo-
nents,whichwill cause damagingcondensation).
Warning
Never operate a cold projector to warm it up.

Voltage Selection
Check Voltage Setting
The VideoMate 2250 is exported throughout the world to
countries with different mains voltages. The projectors
are set to a fixed mains voltage at the factory.
120v Mains
Shipments to countries with 120v mains will be equipped
with a 4A fuse.
220, 230 or 240 Mains
Shipments to countries with 220, 230 or 240v mains will
be equipped with a 2A fuse.
Before you switch on your projector, make sure that
the voltage is correctly adjusted!
An incorrectly adjusted mains voltage can damage the
projector. The voltage Indicator must show your
country’s actual mains voltage.
Setting a Different Operation Voltage
1. Pull out the fuse link compartment by gripping the
small catch.
2. Push the fuse link into the compartment so that the
appliedvoltagecan be seeninthe window ofthe
compartment.
3. Pushthe loaded compartment (withmounting under-
neath)firmlyintotheprojectoropeningprovided.
Warning
For safety, the mains lead must be unplugged.
Important
Make sure that the 120v setting uses a different fuse
than the 220/240v setting.

Quick Start
Quick Start If you are familiar with both the operation of a 35mm slide
projector and your video display, you may follow an
abbreviated start-up procedure.
Before starting, review the precautions on page 5.
To “Quick Start” the VideoMate 2250, proceed as
follows:
1. Check the voltage setting before powering on. Make
sure that the setting above the power cord is correct
for your voltage. In addition, the fuse behind the
voltage settings needs to be checked.
2. Plug the power cable into a suitable power supply.
3. Connect your TV monitor to the composite video and/
or Y/C (S-Video) output connector on the back panel
of the VideoMate.
4. Set the computer input On/Off switch to OFF. Set the
Auto Focus switch to OFF.
5. Load the slide tray onto the projector
6. Turn on the TV monitor and the VideoMate power
switch.
7. Advance to the first slide.
8. Adjust the iris and focus controls on the rear of the
projector and the TV monitor controls to produce a
suitable image.
Note: A very dark slide may require readjustment of the
iris, but a setting can usually be reached that produces
an acceptable display throughout a range of slides.

Slide Tray
Loading and Installing the Slide Tray
The VideoMate 2250 will accept all 80 and 140 Carousel,
Ektagraphic and SAV slide trays. We recommend the 80
slide tray for maximum reliability.
1. Check that the base plate of the slide tray is locked
into the zero position and cannot be rotated.
2. Load the slides upside down for normal front projec-
tion. Replace and lock the cover to prevent damage
in case the tray is dropped or turned over.
3. Place the loaded tray into its zero position on the
projector’s transport ring. The cleft on the slide tray
(zero position) fits into the notch of the transport ring.
Before you switch on the projector, please make sure
that the tray setting switch is in the correct position.
Tray Positioning Index Mark
Projectors are often installed on racks where tray instal-
lation may be difficult and only possible from the rear of
the projector. In this case, the tray positioning mark on
the back of the projector is very helpful: The tray is
properly set when the index mark aligns with the mark
placed on the tray (at slide #20 of the 80-slide tray and at
slide #35 on the 140-slide tray).
Camera Alignment
The following illustration shows the image orienta-
tion adjusting screws on the bottom of your
VideoMate projector.
The four screws marked “A” are used to shift the image
on the monitor left or right. Loosen (do not remove) the
four screws and apply pressure to one of the screw

12
heads to move the internal unit in a sideways motion.
Retighten the four screws.
The two screws marked “B” provide both vertical and
rotational image movements. Turning one screw will tip,
or rotate, the image, while turning both screws will move
the image in a vertical direction.
Caution
Do not turn screws marked “X” or the reference position
will be lost. It should never be necessary to move any
screw far from its “as received” condition. Excessive un-
threading of a screw could result in loss of engagement
and major disassembly.
Changing Slides Slides are changed by using the arrow buttons on top of
the projector. The key moves the tray forward and
the key moves it backward.
To transport the tray quickly in either direction, press and
hold down the correct slide change button until the
position desired is reached. The tray will, however,
automatically stop at #0 and will remain in this position.
If you want to repeat the search run; press the slide
change buttons again.
The VideoMate 2250 can sense when there is a slide in
the gate. Only then will the shutter open and the lamp
achieve its optimum brightness. It is no longer neces-
sary to use dark slides when the slide gate is empty.

Using the power switch
Turn the projector off by the power switch. When the
projector is turned on again, it will complete a system
check and bring the slide tray back to the zero position.
Removing the Slide Tray
In an emergency (such as a transport failure), the tray
can be removed from the projector in any position:
1. First, switch off your projector!
2. Push aside the slide tray lock and hold it while lifting
off the tray.
3. Turn the slide tray over and rotate the base plate until
it clicks into the zero position. Otherwise, the slide
tray cannot be replaced on the projector in the zero
position.
4. Turn the projector on again. The slide remaining in
the slide gate will be ejected by the slide lift and can
be replaced in the slide tray.

Operation
Understanding Which Video Output is Best For You
Composite Video
Standard video image quality which is fine for showing
pictures of objects on a TV monitor.
Y/C (also know as S-Video and S-VHS)
Improved resolution that is less grainy due to the elimina-
tion of dot crawl. Better for presentation of text and
graphic slides, since words are more defined.
Note: You can output both Y/C and composite video
simultaneously if you desire.
SYNC For Genlock
Additional equipment required
To use the genlock feature, a second video source, a
video switcher and the proper input/output cables are
required. We also strongly recommend the use of a
vector scope for the best possible results.
When an external sync signal is input, the display mode
changesfrom the factoryset INT (internalsync) to AUTO
(external sync) automatically.

Features and Functions
Dissolve Operation
The VideoMate 2250 is fully equipped for dissolve
operation and is fully equipped for dissolve operation and
is fully compatible with external dissolve. Control sys-
tems already in existence.
Remote Control In the past, most projectors were controlled by simple
contact closure. Today’s advanced boardroom control
systems, however, are using RS232 for control of the AV
components and room functions.
With the VideoMate 2250, you can electronically control
the projector, lens and camera functions of your slide-to-
video transfer unit by RS232 control from your PC
computer or boardroom control system via the P-Bus-In
(9-pin sub D socket). For connection, use a monitor
cable (1:1, shielded).
A software control package for a PC computer is avail-
able. With the help of the communications language
P-COMProtocol, commands are given directly to the
projector’s microprocessor. Commands are transferred
in binary code. For more information, call Navitar directly
or e-mail us at [email protected].
Motorized Zoom The motorized zoom function allows you to zoom in on a
slide for increased magnification or zoom out to view a
vertical slide.
Random Slide Access
You can pre-program the exact slide sequence you
require or randomly jump to any slide tray position at any
time. For example, you can randomly program your slide
sequence to go from slide #1 to slide #10 and have
different zoom positions (magnifications) and brightness
presets for each slide. Just punch the number of the
desired slide into your control system and press enter.
It’s that simple.
