Introduction to the Presenter
X-Ray, Document & 3-D Object to Video Transfer System
TheNavitarPresenterisanidealpresentationtool.It
enables you to easily convert large documents and blue
prints, 14” x 17” medical X-rays and MRIs as well as 3-D
objects into high definition video images which can be
projected through a video projector, viewed on a TV
monitor or imported into a computer.
The on-screen resolution in incredible. The lack of noise
and outstanding contrast is amazing. Images are pro-
duced with such superior contrast and vivid color rendi-
tion that they can be shown as large projected images
without losing clarity or legibility. Details are clear and
easy to examine.
The Presenter is extremely versatile, making it ideal for
telemedicine and medical applications, as well as use in
courtrooms,boardrooms,auditoriumsandtrainingrooms.
Youcan present your imageson a TV monitoror video
projectorforlargegrouppresentations,orinputtheminto
yourPCfor medical archiving. And because it’scapableof
zooming out to view images as large as 17” x 23”, it can
also be used for tele-engineering applications to view
large C-size documents, blueprints, architectural draw-
ings and 3-D objects.
Description of the Presenter
Navitar’s ultra high resolution presentation system
features 750 TV lines of resolution, a 14X zoom lens, full
X/Yimagepositioning,RS-232 control, Random Access,
aswell as portrait and imagelandscapemodes and
variablebrightnesscontrolonthe baseilluminationsystem.
When viewing medical X-rays or MRI’s, the variable
brightness intensity allows you to clearly view darker or
lighter image areas or help correct for overexposed or
underexposed X-ray film. Sharpness is improved be-
cause you can increase the base illumination and then
step down the iris in the camera system.
The Presenter camera head is mounted on a moveable
overheadframe for X/Yimagepositioning.This feature lets
youzoom in on anydetailanywhere on your X-ray,
document or object. It is easily operated manually with
the joystick control or by RS-232 remote control. The
camerahead also has a portraitorlandscape mode.

Full RS-232 control also enables remote operation of the
camera and lens functions from a PC computer or
boardroom control system. A software package for a PC
computerisavailablefrom Navitar. Forexample,usingour
software package, you can zoom in full screen on any one
of16MRIX-rayimagesandthenviewotherareasatthe

Safety Precautions
To prevent damage to the equipment and operating
personnel, please observe the following precautions:
Make sure that the voltage source contains a satisfactory
path to ground.
Do not operate the unit where water or other 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:
Disconnect the electrical supply.
Allow the unit to cool.
Use only an EVD36V-400W (36 volt, 400 watt) lamp or the
equivalent.Higherwattage lamps willcausesevere
internaldamagetothe camera and electronics.
Thereare no userserviceablecomponents(other than
changing the lamp). Opening the unit will expose danger-
ous voltage levels and sensitive electronic components.
All repairs should be performed by a qualified technician.
To protect the unit from damaging condensation and
thermal shock, certain procedures must be followed:
Incold weather, keep theunit away from moisture.
Eitherkeeptheunitwarmduringtransportation or allow
sufficient time for it to warm up at the destination. (The
goal is to prevent warm, moist air from striking the cold
electronic and optical components which will cause
damagingcondensation).
Warning
Never operate a cold projector to warm it up.

Features and Functions
RS-232 Remote Control
In the past, most products were controlled by simple
contactclosure.Today’sadvanced boardroom control
systems,however, are using RS-232 for control oftheAV
componentsandroomfunctions.
With the Presenter, you can electronically control the
video camera, zoom lens and X/Y image positioning
functions of your video transfer unit by RS-232 control
from your PC computer or boardroom control system via
the RS-232 control port, (9-pin sub D socket) located on
the video output panel. Use a 9-pin D-Sub male to 9-pin
D-Sub female for connection (1:1, shielded).
Asoftwarecontrolpackage for a PC computer is available
fromNavitar.
Motorized ZoomThe motorized zoom function allows you to zoom in on
any position of the X-ray for increased magnification or
zoom out to view the entire 17" x 23" viewing area.
Random Access You can access preset image locations at the push of a
button.You can pre-program the exactsequenceyou
require or randomly jump to any image position at any
time.
Genlockability The Presenter can be genlocked into any video system.
In order to utilize the genlock feature, a second video
source, a video switcher and the appropriate input/output
cablesarerequired.See page 21 for more information.
X/Y Image Positioning
You can zoom in on any specific point on your image and
magnify it up to 14X with the X/Y image positioning
system. You can reset your image to the starting posi-
tion (center) by pressing the home button. This joystick
controlledsystem can be operatedremotelyby RS-232
control. Simply move the joystick to the desired location
and press the zoom button to size your image.

Camera Menu Controls
Various settings on the camera can be controlled by using
the on screen menu displayed on the monitor. Once you
have made your selections they will remain in the
camera’s memory so it is unnecessary to re-set them
each time you use the camera. These functions can also
be controlled by an RS-232 control system. See page 14

Operation
Understanding Which Video Output is Best for You
CompositeVideo
Standard video image quality, which is fine for showing
pictures of objects on a TV monitor.
Y/C (also known as S-Video and S-VHS)
Improvedresolution that is lessgrainydue to the elimina-
tion of dot crawl. Better for presentation of text and
graphic slides because words are more defined.
RGB/Sync
Separate red, green and blue signals are output for
display on devices that are RGB/Sync capable. This is
similar to Y/C in performance, but colors seem more
pleasing to the eye.
Component Video (Y/P R /P B )
Thebestpossiblevideosignalavailable. Requires a
specialmonitororprojector.
Note: You can output Y/C, Composite Video and RGB/
Sync or Component Video simultaneously if you desire.
Understanding Video Cables
Thequalityofyour video cables can affect your picture
quality. Inexpensive and thin cables can cause noise in
the picture and reduce the details and sharpness of your
image. A thicker, higher quality cable with good connec-
torswilloftenprovide a slightly sharper picture.
ThePresenterrequires“grounded shieldvideo”grade
cables, 75 OHM.
Adjusting the Zoom Lens
Using the button on the control panel
Press the zoom button until the desired image magnifica-
tion is selected. This a high resolution 14X zoom lens.
Using RS-232 Control
The zoom lens can also be controlled by RS-232.
