VP-721DS VP-722DS
1.1 A Word about Video Scalers
Kramer’s Digital Video Scalers are designed to convert Composite and S-Video signals to a variety of computer
resolutions. Different versions are required to handle NTSC and PAL video standards. Kramer Video Scalers
have many features to enhance performance. AFM (Adaptive Film Mode) is an automatic 3:2 pull-down
detector that provides clear and crisp de-interlacing video from 24 frames-per-second film. It offers significant
enhancements when viewing movies on a large screen. VT (Vertical Temporal Filter) can remove jagged edges
and other de-interlacing artifacts for video motion sequences. Our Static Picture Detector uses a simple field
merging technique to perform de-interlacing and it is very beneficial for static images or scenes with very little
or no motion.
1.2 Factors Affecting Quality of Results
There are many factors affecting the quality of results when Composite or S-Video signals are de-interlaced and
up-converted (scaled) to computer resolutions. Some basic precautions will ensure the best possible
performance from your Video Scaler.
Output display device
of display device used. Specifically, some video projectors just look better than others.
Distance between the Video Scaler and the display device – This plays a major role in the final result.
Long distances are possible, but special measures should be taken in order to avoid cable losses. These
include using high quality (coax-type) cables or adding line amplifiers.
Output connection cables – Low quality cables are susceptible to interference. They degrade signal
quality due to poor matching and cause elevated noise levels. Therefore, cables should be of the best
quality. Coax-type computer cables are because of their superior internal shielding characteristics.
Interference from neighboring electrical appliances – These can have an adverse effect on signal
quality. For example, an older computer monitor often emits very high electromagnetic fields that can
interfere with the performance of video equipment in its proximity.
– The quality of the output signal will depend largely upon the type and quality

5.2 Connecting the Video Inputs
The Video Scaler provides for a Composite Video or an S-Video input signal for scaling, as well as a computer
signal input (4 in the case of the VP-722DS) that is passed through the unit when it is in the Bypass Mode.
Composite Video - use the composite video cable provided to connect from the composite video output
of the source video equipment to the back of the Video Scaler (the BNC connector marked CV).
S-Video - use the S-Video cable provided to connect from the S-Video output of the source video
equipment to the back of the Video Scaler (the 4-Pin Mini-DIN connector marked SV). S-Video
provides improved performance over Composite Video.
Computer RGB with H&V Sync - connect the source computer’s RGBHV (Red, Green, Blue, H.Sync
and V.Sync) output signal to the Video Scaler’s PC In HD15 connector. In the case of the VP-722DS,
four such source computer signals may be connected to the Video Scaler at the HD15 Input connectors
labeled PC1, PC2, PC3 and PC4. Note – These Computer Input Signals are not scaled, but are available
for pass-through when the Video Scaler is in the Bypass Mode.
5.3 Connecting the Video Output
Connect the Video Scaler’s RGBHV output to the target computer monitor, video projector or other destination
via the 5 BNC connectors or the single HD15 connector labeled Output. The slide switch between these output
connectors is used to select whether the output signal is sent to the 5 BNC’s or the HD15. Note – The output
signal is not available at both simultaneously.
5.4 Connecting the Serial Cable
In addition to the Front Panel Buttons, the VP-722DS can have its Video Input selection made by an external
control device. This is accomplished by connecting the unit’s RS-232 port to an external control system. See
the section on 'RS-232 Control' later in this manual on how to use this control feature.
5.5 Connecting the AC Power
The Video Scaler requires an AC input power source of 100-240VAC@50-60Hz. The unit’s switching power
supply automatically accommodates this input power range. With the Power On/Off switch on the rear of the
Video Scaler in the Off position, plug the AC Cable supplied into the AC Receptacle on the back of the unit and
plug the AC Cable into the power outlet.
5.6 Connecting the Audio Control (VP-722DS Only)
The VP-722DS has the ability to control an external Kramer audio routing switcher (with contact closure
control) for audio-follow-video applications. This is accomplished by providing a set of contact closures that
follow the Video Input selection. This connector strip is located on the rear panel of the unit and a “normallyopen” pair of contacts is provided to correspond to each input: SV, CV, PC1, PC2, PC3 and PC4. When a
particular video input is selected via the front panel Input Button, its respective set of contacts “close”, thus
providing an indication to the external audio switcher. Please refer to the Kramer audio switcher’s user manual
for instructions on connecting the Video Scaler’s contacts to the audio switcher’s contacts.
5.7 Turning the Video Scaler On
Make sure that all cables are connected and that all other equipment is turned on. The Video Scaler’s AC Power
Switch on the rear panel should be switched to the On position. When the Video Scaler is switched on, some of
the LED indicators on the front panel will illuminate. If a video input signal is present, an image should be seen
on the output display device. If there is no picture on the display device, go to the Troubleshooting section.

Scaler. It also provides information on the Status Indications given by the Front Panel LED’s.
7 INPUT SELECTON
The Video Scaler’s Input can be chosen from the Front Panel in two ways:
Automatic Input Select Mode - the Video Scaler determines when a video signal is present at either the
Composite Video or S-Video input connector and automatically selects that as the active input. If a signal is
present at both inputs, priority is given to the S-Video input. E.g., this feature allows input selection to be
done by switching power on or off to the source video devices.
Manual Input Select Mode - allows manual selection of which input video signal is chosen. Repeatedly
pressing the button toggles through the available inputs:
a) VP-721DS = Composite Video, S-Video or PC.
b) VP-722DS = Composite Video, S-Video, PC1, PC2. PC3 or PC4.
Note – The PC Inputs are simply pass-through connections to the output and are not scaled.

9 VIDEO SIGNAL ADJUSTMENT
The Video Scaler has an integral processing amplifier capable of adjusting various signal parameters of the
incoming Composite or S-Video signal. This is done by using the Select Button to choose the desired parameter
and then using the + and – Buttons to make the adjustment.
9.1 Select, + and – Buttons
Repeatedly pressing the Select Button toggles through the available adjustments, as indicated by the respective
LED. Pressing the + Button increases the value of the selection, while pressing the – Button decreases the
value. The LED will flash rapidly when the end of the adjustment range is reached. The settings are
automatically saved after adjustment and will remain in memory, even when power is switched off. Pressing
the + and – Buttons at the same time returns all settings to the factory preset levels. Note - These adjustments
have no effect on the incoming computer signals, which are simply passed through the Video Scaler.
Horiz LED – The Horizontal Position LED illuminates when the Select Button is pressed repeatedly
until this parameter is available for adjustment. This is for horizontally centering the image. When this
LED is illuminated, pressing the + Button moves the position of the image to the right on the output
screen. Pressing the – Button moves the position of the image to the left on the output screen.
Vert LED – The Vertical Position LED illuminates when the Select Button is pressed repeatedly until
this parameter is available for adjustment. This is for vertically centering the image. When this LED is
illuminated, pressing the + Button moves the image up on the output screen. Pressing the – Button
moves the image down on the output screen.

12 TROUBLESHOOTING
If the recommended actions still do not result in satisfactory operation, please consult your Kramer Dealer.
Before seeking technical assistance, if the problem is image related, please try to find out the screen resolution
and refresh rate being used from the computer and if the problem only affects one particular resolution.
Problem Remedy
The picture on the video
display is black and
white.
There is no picture on
the video monitor.
Some colors come out
wrong on the video
monitor.
How can I reduce
smearing?
1. Check the condition of the cables being used. In particular, a
faulty S-Video able will cause this problem.
2. Make sure that the version of the Video Scaler (NTSC or PAL)
matches the video standard of the equipment you are using:
NTSC or PAL.
3. Ensure that the color controls on your computer monitor or video
projector are all set correctly.
4. Ensure that the Color adjustment on the Video Scaler is not
adjusted completely down. It may be necessary to reset the video
levels by pressing the + and – Buttons simultaneously.
1. If no LED’s on the Video Scaler are illuminated, ensure that the
proper AC Power is being supplied to the unit and check the fuse
(The procedure located elsewhere in this manual).
2. If the LED’s are illuminated: a) Check that the output switch on
the rear panel of the Video Scaler is set to the proper position,
either BNC or HD15, depending upon which method is used to
connect to the display, b) Check that the output you are using
from the Video Scaler is also connected at the unit and the
display, and c) Check that your display is switched on and set to
the correct input and that its Brightness and Contrast are set
correctly.
1. Try altering the color (saturation), hue (tint) contrast and
brightness settings on your display. These are usually set up for
viewing computer images, which may be somewhat different
from viewing images that have been up-converted from video.
2. Make sure your output cable assembly is not faulty. Perhaps the
Red, Green or Blue signal is not being passed through the cable.
1. Smearing usually occurs when a Composite Video input is used
and is generally unavoidable, unless you can switch to using SVideo. It occurs because the luminance and color information is
combined as one signal and the two parts have to be 'bandwidthlimited' to avoid them interfering with each other.
2. Using good quality video cable will help towards reducing this
affect.
