KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The VS-2DVA is an all-in-one 2x1 switcher for DVI, XGA/UXGA1, and
unbalanced audio signals.
In particular, the VS-2DVA:
Equalizes and reclocks the DVI input, effectively reconstructing and
retransmitting the DVI signal
Has an XGA/UXGA1 video bandwidth of 340MHz, that ensures
transparent operation is achieved at the highest resolutions
Comes with contact closure remote control for forced operation
Is housed in a half 19" rack size and is 12VDC fed
In addition, with the high quality VS-2DVA, both:
DVI inputs have their own corresponding audio inputs, and the DVI
output has its own audio output
XGA/UXGA1 inputs have their own corresponding audio inputs, and the
XGA/UXGA output has its own audio output
DVI and XGA/UXGA1 signals can be switched separately or ganged
(switched together)
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 VS-2DVA 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.

Connecting the VS-2DVA 2x1 DVI / XGA / Audio Switcher
5 Connecting the VS-2DVA 2x1 DVI / XGA / Audio Switcher
To connect1 your VS-2DVA 2x1 DVI / XGA / Audio Switcher, as the example
in Figure 2 illustrates, do the following2:
1. Connect an XGA source (for example, a laptop’s digital graphics card) to
the INPUT 1 XGA 15-pin HD connector, and connect its audio to the IN 1
3.5mm mini jack3 (using a separate cable or the Kramer C-GMA/GMA
cable4: VGA HD15M +Audio jack to VGA HD15M +Audio jack).
2. Connect a DVI source (for example, a DVI computer graphics source) to
the DVI INPUT 1 connector, and connect an unbalanced stereo audio
source to the corresponding AUDIO input 3.5mm mini jack3.
3. Connect the XGA 15-pin HD output connector5 to the XGA acceptor (for
example, an analog display) and connect the corresponding AUDIO output
3.5mm mini jack to an unbalanced stereo audio acceptor3.
4. Connect the DVI output connector5 to the DVI acceptor (for example, a
projector) and connect the corresponding AUDIO output 3.5mm mini jack
to an unbalanced stereo audio acceptor3 (for example, the Kramer 903
Personal Stereo Amplifier).
5. Connect6 the contact closure remote control PINS (optional), see section 5.1.
6. Connect6 the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity.
1 You do not have to connect all the inputs
2 Switch OFF the power on each device before connecting it to your VS-2DVA. After powering up your VS-2DVA, switch
on the power on each device
3 The audio connections are not illustrated in Figure 2
4 Not supplied. The complete list of Kramer cables is on our Web site at http://www.kramerelectronics.com
5 You do not have to connect both outputs. For example, if you only want to switch DVI, connect only that output of the
VS-2DVA, and leave the XGA output unconnected
6 The connection is not illustrated in Figure 2

Connecting the VS-2DVA 2x1 DVI / XGA / Audio Switcher
5.1 Connecting the Contact Closure Remote Control PINS
You can use the contact closure remote control PINS to:
Route an input, and its corresponding unbalanced stereo audio output, by
remote control
Toggle the GANG selection, that is, switching the DVI and XGA inputs
in a combined action or separately. (By default, at the moment that the
GANG function is selected, the DVI selection takes priority over the
XGA selection), see section 6.2
To do so, momentarily connect the appropriate1 REMOTE terminal block
connector PIN to the REMOTE terminal block connector Ground PIN (see the
illustration in Figure 3). The appropriate front panel push button(s)
illuminate(s) as the selected input(s) routes to the appropriate output(s).
Do not interconnect PIN DVI 1, PIN DVI 2, PIN XGA 1, PIN XGA 2, or PIN GANG
Do not connect more than one PIN to the Ground PIN at the same time
Figure 3: Connecting the Contact Closure Remote Control PINS
1 To route DVI Input 1, connect PIN DVI 1 to the Ground PIN; to route DVI Input 2, connect PIN DVI 2 to the Ground PIN.
To route XGA Input 1, connect PIN XGA 1 to the Ground PIN; to route XGA Input 2, connect PIN XGA 2 to the Ground
PIN. To route the GANG, connect PIN GANG to the Ground PIN

Operating the VS-2DVA 2x1 DVI / XGA / Audio Switcher
6 Operating the VS-2DVA 2x1 DVI / XGA / Audio Switcher
The VS-2DVA automatically selects DVI INPUT 1 and XGA INPUT 1 when
the VS-2DVA is turned ON (see Figure 4):
Figure 4: Initial Status of the SELECTOR Buttons
You can switch one of the two DVI inputs1 to the corresponding DVI output2,
and one of the two XGA inputs1 to the corresponding XGA output2, either:
Separately, see section 6.1
Together (Ganged), see section 6.2
6.1 Switching DVI and XGA Signals Separately
To switch a DVI input and an XGA input in two separate actions:
If the GANG (DVI + XGA) button is illuminated, press to toggle for
separate selection. The button no longer illuminates
Press one of the two DVI SELECTOR buttons
The pressed button illuminates, indicating selection and outputting of that
video and audio source
Press one of the two XGA Selector buttons
The pressed button illuminates, indicating selection and outputting of that
video and audio source
6.2 Switching DVI and XGA Signals Together (Ganged)
To switch a DVI input and an XGA input in a combined action:
If the GANG (DVI + XGA) button is not illuminated, then press to toggle
for GANGED operation
The button is now illuminated
Press one of the two DVI or XGA SELECTOR buttons
The pressed button illuminates, together with the XGA or DVI
SELECTOR button corresponding to the same input number, indicating
selection and outputting of those video and audio sources
