3 Overview
The Kramer VP-436 is a high quality presentation switcher and scaler. It
accepts one of seven inputs: a component video
1
on RCA connectors, computer
graphics on a 15-pin HD connector, composite video on an RCA connector,
s-Video on a 4-pin connector and two HDMI signals. It scales the video,
embeds the audio, and outputs the signal to the HDMI output as well as to a
computer graphics output, an RGBHV video output together with a digital audio
output and an analog stereo audio output.
The VP-436 is HDTV compatible and the resolution can be up- or down-
scaled as follows:
Native, VGA, SVGA, XGA, SXGA, UXGA, 480i, 480p, 576i, 576p, 720p
2
, 1080i
2
,
1080p
2
, WXGA, WSXGA, WUXGA, 1280x800, 1440x900, 1400x1050
The VP-436 Presentation Switcher / Scaler:
Has analog audio inputs and digital (S/PDIF) and analog stereo audio
outputs
Automatically detects and selects the audio source for the HDMI input.
Default selection is HDMI – if this is not present, then the machine uses
the audio from the analog input
Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
Has a non-volatile memory that retains the last settings used
Supports firmware upgrade
3
via RS-232
Control your VP-436:
Directly, via the front panel push buttons
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
Remotely, from the infrared remote control transmitter
The VP-436 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240 VAC universal switching power supply.
1 Also known as Y, Pb, Pr, Y, Cb, Cr and YUV; compatible with both SD and HD component

3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the maximum high-definition image and sound quality in use
today. Note that Kramer Electronics Limited is an HDMI Adopter
2
and an HDCP
Licensee
3
.
In particular, HDMI
4
:
Provides a simple
5
interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and video monitor, such as a
digital flat LCD / plasma television (DTV), over a single lengthy
6
cable
Supports standard, enhanced, high-definition video, and multi-channel
digital audio
7
on a single cable
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
8
, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
Has the capacity to support existing high-definition video formats (720p,
1080i, and 1080p/60), standard definition formats such as NTSC or PAL,
as well as 480p and 576p.
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
2 See http://www.hdmi.org/about/adopters_founders.asp
3 See http://www.digital-cp.com/list/
4 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
licensing LLC
5 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
6 HDMI technology has been designed to use standard copper cable construction at up to 15m
7 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
8 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

3.2 Recommendations for Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise-
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position
your Kramer VP-436 away from moisture, excessive sunlight and dust

Installing the VP-436 in a Rack

5 Installing the VP-436 in a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5°to +45°C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20°to +70°C (-4°to 158°F)
Storage humidity range 5 to 95% RHL, non-condensing

CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:

6 Connecting the VP-436 Presentation Switcher / Scaler
To connect
1
your VP-436, as illustrated in the example in Figure 2, do the
following:
1. Connect an HDMI source (for example, a DVD player) to the HDMI 1
VIDEO INPUT connector
2
.
2. Connect a computer graphics source to the VGA 15-pin HD VIDEO
INPUT connector.
3. Connect a composite video source (for example, a composite video player)
to the CV VIDEO INPUT RCA connector.
4. Connect an s-Video source (for example, an s-Video player) to the YC
4-pin VIDEO INPUT connector.
5. Connect a component video source (for example, a component video
player) to the COMP 1 PR, PBand Y, VIDEO INPUT RCA connectors.
6. Connect the audio input signals to the AUDIO IN terminal block
connectors, as required (not shown in Figure 2).
7. Connect the RGBHV VIDEO OUTPUT BNC connectors to an RGBHV
acceptor (for example, an RGBHV display).
8. Connect the HDMI VIDEO OUTPUT connector to an HDMI acceptor (for
example, a plasma display).
9. Connect the VGA VIDEO OUTPUT 15-pin HD connector to a VGA
acceptor (for example, a projector).
10. Connect the audio output signals to the OUT stereo analog audio acceptor
and/or the digital audio acceptor, as required (not shown in Figure 2).
11. Connect the power cord
3
(not shown in Figure 2).
1 You do not have to connect all the inputs and outputs, connect only those that are required
2 Alternatively, you can connect the DVI connector on the DVD player to the HDMI connector on the VP-436 via a
DVI-HDMI adapter. When using this adapter, you can connect the audio signal via the terminal block connector
3 We recommend that you use only the power cord that is supplied with this machine
