Overview

3 Overview

The VP-4x4 is a true 4x4 matrix switcher for computer graphics (VGA/XGA)

signals and balanced stereo audio signals. The VP-4x4 enables the user to

simultaneously route any or all of the four inputs to any or all of the four

outputs.

In addition, the VP-4x4 includes:

 A video bandwidth of 440MHz that ensures transparent VGA/XGA

performance

 Easy-to-connect detachable terminal block connectors on which the audio

signals reside

 DC coupled inputs and 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

Control the VP-4x4 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 (including the Kramer RC-IR1 external remote receiver).

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 that may

adversely influence signal quality and position your Kramer VP-4x4 away

from moisture, excessive sunlight and dust

Installing the VP-4x4 on a Rack

5 Installing the VP-4x4 on a Rack

This section describes what to do before installing on a rack and how to rack

mount.

Before Installing on a Rack

Before installing on a rack, be sure that the environment is

within the recommended range:

Operating temperature range +5 to +45 Deg. Centigrade

Operating humidity range 5 to 65 % RHL, non-condensing

Storage temperature range -20 to +70 Deg. Centigrade

Storage humidity range 5 to 95% RHL, non-condensing

CAUTION!!

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 supply

connections other than direct connections to the

branch circuit (for example, the use of power strips),

and that you use only the power cord that is supplied

with the machine.

How to Rack Mount

To rack-mount the machine:

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.

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
