Getting Started

Overview

3 Overview

The VP-2x2 is a high performance matrix switcher for VGA/SVGA/XGA/UXGA

signals and balanced stereo audio signals. The user can simultaneously route

an input to one or both outputs

In addition, the VP-2x2 includes:

Videobandwidththatexceeds400MHz, ensuringtransparent

performance in all applications

Audio-follow-video switching and audio breakaway (when audio and

video are switched separately)

A TAKE button that allows the user to pre-select a setting and then

activate it

A LOCK button to prevent tampering via the front panel

Control via the front panel buttons, or remotely by RS-232 serial

commands transmitted by a touch screen system, PC, or other serial

controller

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-2x2 in a

location free from moisture and away from excessive sunlight and dust

Caution – No operator-serviceable parts inside unit.

Warning – Use only the Kramer Electronics input power

wall adapter that is provided with this unit

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.

1 Input 1 (or 2) to outputs 1 and 2 simultaneously, or input 1 (or 2) to output 1 and input 2 (or 1) to output 2

2 For example: model number AD2512C, part number 2535-000251

5 Connecting the VP-2x2 2x2 XGA/Audio Matrix Switcher

This section describes how to connect:

The VP-2x2 rear panel (see section 5.1)

A balanced stereo audio input/output (see section 5.2)

The VP-2x2 to a controlling device via RS-232 (see section 5.2)

5.1 Connecting the VP-2x2 2x2 XGA/Audio Matrix Switcher Rear Panel

To connect

the VP-2x2, as illustrated in the example in Figure 2, do the

following

1. Connect the VGA/UXGA computer graphics sources to the INPUT 15-

pin HD computer graphics video connectors.

2. Connect the balanced

stereo audio sources to the AUDIO IN balanced

stereo audio 5-pin terminal block connectors.

3. Connect the OUTPUT 15-pin HD computer graphics video connectors to

the VGA/UXGA video acceptors (for example, displays).

4. Connect the AUDIO OUT terminal block connectors to the balanced

stereo audio acceptors (for example, amplifiers with speakers).

5. Connect a PC and/or controller (if required) to the RS-232 port (see

section 5.2).

6. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity (not shown in Figure 2).

1 You do not have to connect both inputs or both outputs

2 Switch OFF the power on each device before connecting it to your VP-2x2. After connecting your VP-2x2, switch on its

power and then switch on the power on each device

5.3 Connecting a PC

You can connect a PC (or other controller) to the VP-2x2 via the RS-232 port

for remote control, and for upgrading the firmware.

To connect a PC to a VP-2x2 unit, using the Null-modem adapter provided

with the machine (recommended):

Connect the RS-232 9-pin D-sub rear panel port on the VP-2x2 unit to the

Null-modem adapter and connect the Null-modem adapter with a 9-wire

flat cable to the RS-232 9-pin D-sub port on your PC

To connect a PC to a VP-2x2 unit, without using a Null-modem adapter:

Connect the RS-232 9-pin D-sub port on your PC to the RS-232 9-pin

D-sub rear panel port on the VP-2x2 unit, forming a cross-connection

, as
