3 Overview
Your Kramer VP-211K is a high performance 2x1 automatic switcher for
computer graphics video (UXGA) and stereo audio signals. The VP-211K
detects the presence of the active VGA-type input signal from either IN 1 (the
default1) or IN 2—depending on how the DEFAULT INPUT switch is set, as
section 5.2 describes—and automatically routes it to the acceptor connected
to the UXGA OUT and the AUDIO OUT connectors.
In addition, the VP-211K:
With its video bandwidth of 00MHz, ensures transparent operation at the
highest resolutions
Automatically switches the stereo audio signal with the video signal
(audio-follow-video) when switching the active input to the output
Includes a DEFAULT INPUT switch for selecting the default UXGA
master source signal
Includes a loop UXGA output for connecting an additional display
Comes with contact closure remote control for forced operation
Uses active switching and has flexible sync detection and reconstruction
circuitry
Includes the Kramer innovative integrated sync processing; KRISP™
technology, which lets you achieve a sharp, stable image when the sync
level is too low, by restoring the sync signal waveform
Achieving the best performance means:
Connecting 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)
Avoiding interference from neighboring electrical appliances and
positioning your VP-211K away from moisture, 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 unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

This section describes how to:
Connect the VP-211K (see section 5.1)
Select the default master source signal (see section 5.2)
Connect the REMOTE connector (see section 5.3)
5.1 Connecting the VP-211K Automatic UXGA / Audio Switcher
To connect the VP-211K, as illustrated in the example in Figure 2, do the
following1:
1. Connect a UXGA/audio source (for example, a PC graphics card) to the
UXGA IN 1 15-pin HD connector and to the AUDIO IN 1 mini plug
connector.
2. Set the DEFAULT INPUT switch to IN 1 (the factory preset default), as
section 5.2 describes.
3. Connect a UXGA/audio source (for example, a PC graphics card) to the
UXGA IN 2 15-pin HD connector and to the AUDIO IN 2 mini plug
connector.
4. Connect the UXGA OUT 15-pin HD connector and the AUDIO OUT mini
plug connector to the acceptor (for example, a display with speakers).
5. If required, connect an additional display to the UXGA LOOP OUT
15-pin HD connector.
6. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.
1 Switch OFF the power on each device before connecting it to your VP-211K. After powering up your VP-211K, switch on
the power on each device

5.2 Selecting the Default Master Source Signal
The DEFAULT INPUT switch is factory preset to IN 1 and the VP-211K will
detect the presence of the master source signal at the UXGA IN 1 connector.
If you connect active sources to both the UXGA IN 1 and the UXGA IN 2
connectors, the source at the UXGA IN 1 connector takes priority over the
source at the UXGA IN 2 connector and it is routed to the UXGA OUT and
the AUDIO OUT connectors (audio follows video).
You can change the default so that the VP-211K automatically detects an
active source signal from UXGA IN 2, by setting the DEFAULT INPUT
switch to IN 2. When active, the source at the UXGA IN 2 connector takes
priority over the source at the UXGA IN 1 connector and it is routed to the
UXGA OUT and the AUDIO OUT connectors (audio follows video).
If the VP-211K detects:
No signal1 at the UXGA IN 1 input (when IN 1 is selected as the default),
the VP-211K routes the signal from the source at UXGA IN 2 to the
UXGA OUT and the AUDIO OUT connectors. Similarly, if the VP-211K
detects no signal at the UXGA IN 2 input (when IN 2 is selected as the
default), the VP-211K routes the signal from the source at UXGA IN 1 to
the UXGA OUT and the AUDIO OUT connectors
A signal from the UXGA source at UXGA IN 1 input (when IN 1 is
selected as the default), while routing the signal from the UXGA source
at UXGA IN 2, the VP-211K will reroute the signal from the UXGA
source at UXGA IN 1 to the UXGA OUT and the AUDIO OUT
connectors. Similarly, if the VP-211K detects a signal from the UXGA
source at UXGA IN 2 input (when IN 2 is selected as the default), while
routing the signal from the UXGA source at UXGA IN 1, the VP-211K
will reroute the signal from the UXGA source at UXGA IN 2 to the
UXGA OUT and the AUDIO OUT connectors
No signal at all (that is, when there is no active input from a source at
UXGA IN 1 or at UXGA IN 2), the VP-211K will still route UXGA IN 2
to the UXGA OUT, and continue to examine UXGA IN 1 input (when IN
1 is selected as the default), switching back to it when it detects a valid
signal. Similarly, if the VP-211K detects no signal at all (when IN 2 is
selected as the default), it will still route UXGA IN 1 to the UXGA OUT,
and continue to examine the UXGA IN 2 input, switching back to it when
it detects a valid signal
1 Perhaps no source is connected, or that source is connected but its power is OFF

5.3 Connecting the REMOTE Terminal Block Connector
You can force the routing of one of the two inputs to the UXGA output by
remote control. To do so, connect the appropriate REMOTE input terminal
block connector pins to a contact closure switch1. For example, as Figure 3
illustrates, to route REMOTE IN1 to the UXGA output, connect PIN IN1 to
PIN G (Ground). To route REMOTE IN2 to the UXGA output, connect PIN
IN2 to PIN G.
Do not connect both the REMOTE IN1 and the REMOTE IN2 to PIN G
simultaneously
Route input 1 to the output,
by attaching PIN IN1 to PIN
G:
Route input 2 to the output,
by attaching PIN IN2 to PIN
G:

is removed
