Overview

3 Overview
Your Kramer VP-211DS is a high performance 2x1 automatic switcher for
VGA/SVGA/XGA/UXGA and stereo audio signals. The VP-211DS detects the
presence of the active VGA-type input signal from either IN 1 (the default
1
) or
IN 2—depending on how the DEFAULT SELECT switch is set, as section 5.2
describes—and automatically routes it to the acceptor connected to the XGA
OUT and the AUDIO OUT connectors.
In addition, the VP-211DS:
With its video bandwidth exceeding 00 MHz, 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 SELECT switch on the underside for selecting the
default XGA master source signal
Includes a loop XGA 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; KR-ISP™
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-211DS 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 unit
2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

This section describes:
Connecting the VP-211DS (see section 5.1)
Selecting the default master source signal (see section 5.2)
Connecting the REMOTE connector (see section 5.3)
5.1 Connecting the VP-211DS Automatic VGA / Audio Switcher
To connect the VP-211DS, as illustrated in the example in Figure 3, do the
following
1
:
1. Connect a VGA/Audio source (for example, a PC) to the XGA IN 1
15-pin HD connector and to the AUDIO IN 1 mini plug connector. Set the
underside DEFAULT SELECT switch to IN 1 (the factory preset default),
as section 5.2 describes.
2. Connect a VGA/Audio source (for example, a PC) to the XGA IN 2
15-pin HD connector and to the AUDIO IN 2 mini plug connector.
3. Connect the XGA OUT 15-pin HD connector and the AUDIO OUT mini
plug connector to the acceptor (for example, a video monitor with
speakers).
4. If required, connect an additional monitor to the XGA LOOP OUT 15-pin
HD connector.
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
6. If required, set the Hs and Vs switches for input 1 (H1 and V1) and input
2 (H2 and V2).
1 Switch OFF the power on each device before connecting it to your VP-211DS. After powering up your VP-211DS, switch
on the power on each device

5.2 Selecting the Default VGA Master Source Signal
The DEFAULT SELECT switch is factory preset to IN 1 and the VP-211DS
will detect the presence of the master source signal at the XGA IN 1 connector.
If you connect active sources to both the XGA IN 1 and the XGA IN 2
connectors, the source at the XGA IN 1 connector takes priority over the source
at the XGA IN 2 connector and it is routed it to the XGA OUT and the AUDIO
OUT connectors (audio follows the video).
You can change the default so that the VP-211DS automatically detects an
active source signal from XGA IN 2, by setting the DEFAULT SELECT
switch to IN 2. When active, the source at the XGA IN 2 connector takes
priority over the source at the XGA IN 1 connector and it is routed to the XGA
OUT and the AUDIO OUT connectors (audio follows the video).
If the VP-211DS detects:
No signal
1
at the XGA IN 1 input (when IN 1 is selected as the default), the
VP-211DS routes the signal from the source at XGA IN 2 to the XGA
OUT and the AUDIO OUT connectors. Similarly, if the VP-211DS detects
no signal at the XGA IN 2 input (when IN 2 is selected as the default), the
VP-211DS routes the signal from the source at XGA IN 1 to the XGA
OUT and the AUDIO OUT connectors
A signal from the VGA source at XGA IN 1 input (when IN 1 is selected as
the default), while routing the signal from the VGA source at XGA IN 2,
the VP-211DS will reroute the signal from the VGA source at XGA IN 1 to
the XGA OUT and the AUDIO OUT connectors. Similarly, if the
VP-211DS detects a signal from the VGA source at XGA IN 2 input (when
IN 2 is selected as the default), while routing the signal from the VGA
source at XGA IN 1, the VP-211DS will reroute the signal from the VGA
source at XGA IN 2 to the XGA OUT and the AUDIO OUT connectors
No signal at all (that is, when there is no active input from a source at XGA
IN 1 or at XGA IN 2), the VP-211DS will still route XGA IN 2 to the XGA
OUT, and continue to examine XGA 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-211DS detects no signal at all (when IN 2 is selected as the default),
it will still route XGA IN 1 to the VGA OUT, and continue to examine the
XGA 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 Connector
You can force the routing of one of the two inputs to the XGA output by remote
control. To do so, connect the appropriate REMOTE input terminal block
connector pins to a dry contact switch
1
. For example, as Figure 4 illustrates, to
route REMOTE IN 1 to the VGA output, connect PIN IN 1 to PIN G (Ground).
To route REMOTE IN 2 to the VGA output, connect PIN IN 2 to PIN G.
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 4: Remote Terminal Block Connector
When both XGA IN 1 and XGA IN 2 are connected, the signal from XGA IN 1
routes to the output. However, you can force the routing of XGA IN 2 to the
output by attaching PIN IN 2 to PIN G. If no input is present on XGA IN 1, you
can still force the routing of the output from XGA IN 1 (displaying a blank
screen) by attaching PIN IN 1 to PIN G.
1 Note that the connection should be permanent, since the VP-211DS will revert to an automatic switcher when the
connection is removed
