2 VP-4x4K - Getting Started
2 Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
•Review the contents of this user manual
Use Kramer high performance high resolution cables
Use only the power cord that is supplied with this machine
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid 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 that may adversely
influence signal quality
•Position your Kramer VP-4x4K away from moisture, excessive sunlight and
dust

VP-4x4K - Overview 3
3 Overview
The VP-4x4K is a true 4x4 matrix switcher for computer graphics (up to and exceeding
UXGA) signals and balanced stereo audio signals. The VP-4x4K lets you
simultaneously route any or all of the four inputs to any or all of the four outputs.
In addition, the VP-4x4K features:
•A video bandwidth of 400MHz that ensures transparent UXGA performance
•DC coupled inputs and outputs
•A selectable delayed switching mode (ranging from 0 to 3.5sec, in
increments of 0.5sec) for clean transitions (seamless switching) when
switching between non-genlocked sources
•Audio gain control for the inputs and the outputs
•Audio-follow-video and breakaway options
•Storing and recalling setup options
•A TAKE button for precise switch control that lets you execute multiple
switches all at once
•A LOCK button to prevent tampering with the front panel
•The ability to automatically detect connected input signals (the respective
button illuminates in green)
•Our innovative integrated sync processing; KRISP™ technology that lets you
achieve a sharp, stable image when the sync level is too low, by restoring
the sync signal waveform
Control the VP-4x4K using the front panel buttons, or remotely via:
•RS-485 or RS-232 serial commands transmitted by a touch screen system,
PC, or other serial controller
•The Kramer RC-IR3 infrared remote control transmitter
•The Ethernet

VP-4x4K - Installing in a Rack 7
4 Installing in a Rack
This section provides instructions for rack mounting the unit.
Before Installing in a Rack How to Rack Mount
Before installing in a rack, be sure that the
environment is within the recommended range:
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.
When installing on a 19" rack, avoid hazards by
taking care that:
. 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.
. Once rack mounted, enough air will still flow
around the machine.
. The machine is placed straight in the correct
horizontal position.
. 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.
. 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.

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:
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

5 Connecting the VP-4x4K
Always switch off the power to each device before connecting it to your
VP-4x4K. After connecting your VP-4x4K, connect its power and then
switch on the power to each device.
This section describes how to:
•Connect the VP-4x4K rear panel (see Section 5.1)
•Connect a balanced/unbalanced stereo audio output (see Section 5.2)
•Connect the stereo audio output (see Section 5.3)
•Connect several VP-4x4K machines (see Section 5.4)
•Connect to the Ethernet (see Section 5.5)
•Set the DIP-switches (see Section 5.6)
5.1 Connecting the VP-4x4K Rear Panel
To connect the VP-4x4K, as illustrated in the example in Figure 2, do the
following:
1. Connect up to four computer graphics video sources to the 15-pin HD INPUT
connectors (from INPUT 1 to INPUT 4).
2. Connect up to four unbalanced stereo audio sources (for example, the audio
source of the computer) to the AUDIO INPUT 3.5mm mini-plug connectors
(from 1 to 4).
Alternatively, you can connect a separate audio source (as shown for input 1 in
Figure 2), or no source at all.
3. Connect the four 15-pin HD OUTPUT connectors to up to four computer
graphics video acceptors (for example, displays).
4. Connect the four AUDIO OUTPUT terminal block connectors to up to four
balanced stereo audio acceptors (for example, balanced stereo audio
amplifiers with speakers).
See Section 5.2.
5. Set the DIP-switches (see Section 5.6).

6. As an option, you can connect a PC and/or controller to the RS-232 port
(see Section 5.3), the RS-485 port (see Section 5.4) and the Ethernet (see
Section 5.5).
7. Connect the power cord.

5.3 Connecting to the VP-4x4K via RS-232
You can connect to the VP-4x4K via an RS-232 connection using, for example, a
PC. Note that a null-modem adapter/connection is not required.
•To connect to the VP-4x4K via RS-232, connect the RS-232 9-pin D-sub
rear panel port on the VP-4x4K unit via a 9-wire straight cable (pin 2 to pin
2, pin 3 to pin 3, pin 5 to pin 5) to the RS-232 9-pin D-sub port on your PC

VP-4x4K - Connecting the VP-4x4K 11
5.4 Cascading Machines
You can cascade up to 16 VP-4x4K units with control from a PC or serial
controller.
To cascade 16 individual VP-4x4K units via RS-485, as illustrated in the example
in Figure 5, do the following:
1. Connect the sources and acceptors (see Section 5.1).
2. Connect the RS-232 port of the first VP-4x4Kunit to a PC.
3. Connect the RS-485 terminal block port on the first VP-4x4Kunit to the
RS-485 port on the second VP-4x4K unit and so on, connecting all the
RS-485 ports.
4. Set the first VP-4x4K unit as Machine # 1 and the following VP-4x4K units
as Machine # 2 to Machine # 16 (see Section 6.4).
5. On the first and last VP-4x4Kunits, set the RS-485 TERM DIP-switch to ON,
terminating the RS-485 line at 120Ω(see Section 5.6), and set this DIP-
switch to OFF on the other VP-4x4K units.
