VP-211K - 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
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 (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VP-211K away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

VP-211K - Overview
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 default) or IN
2—depending on how the DEFAULT INPUT switch is set, as Section 4.2
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 300MHz, 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
Lets both PC inputs pass the EDID information from the acceptor (display) to
the source (laptop/PC)

4 Connecting the VP-211K
Always switch off the power to each device before connecting it to your
VP-211K. After connecting your VP-211K, connect its power and then
switch on the power to each device.
To connect the VP-211K as illustrated in the example in Figure 2:
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
described in Section 4.2
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.

4.1 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 switch. 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.
Note that the connection should be permanent, since the VP-211K reverts to an automatic
switcher when the connection is removed.

VP-211K - Connecting the VP-211K
Do not connect both the REMOTE IN 1 and the REMOTE IN 2 to
PIN G simultaneously.
Route input 1 to the output, by
attaching PIN IN 1 to PIN G:
Route input 2 to the output, by
attaching PIN IN 2 to PIN G:
Figure 3: REMOTE Terminal Block Connector
4.2 Selecting the Default Master Source Signal
The DEFAULT INPUT switch is factory preset to IN 1 and the VP-211K detects 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 signal (perhaps no connected source, or a source is connected and
powered OFF) 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 reroutes 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 reroutes 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 still routes 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 still
routes 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
