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
1
.
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
2
.
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
1
the VP-2x2, as illustrated in the example in Figure 2, do the
following
2
:
1. Connect the VGA/UXGA computer graphics sources to the INPUT 15-
pin HD computer graphics video connectors.
2. Connect the balanced
3
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
3
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
