3 Overview

The VS-2DVA is an all-in-one 2x1 switcher for DVI, XGA/UXGA2, 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/UXGA1video bandwidth of 350MHz, that ensures

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Your VS-2DVA 2x1 DVI / XGA / Audio Switcher

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/UXGA1inputs have their own corresponding audio inputs, and the

XGA/UXGA output has its own audio output

DVI and XGA/UXGA1signals 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

Connecting the VS-2DVA 2x1 DVI / XGA / Audio Switcher

5 Connecting the VS-2DVA 2x1 DVI / XGA / Audio Switcher

To connect your VS-2DVA 2x1 DVI / XGA / Audio Switcher, as the example

in Figure 2 illustrates, do the following1:

1. Connect up to 2 XGA/UXGA sources to the 2 HD15F input connectors,

and connect up to 2 unbalanced stereo audio sources to the 2

corresponding AUDIO input 3.5mm mini jacks, as follows:

Connect the XGA source 1 (for example, a laptop’s digital graphics card)

to the INPUT 1 XGA HD15F connector, and its audio to the IN 1 3.5mm mini

jack, for example, using a Kramer C-GMA/GMA cable (VGA HD15M

+Audio jack to VGA HD15M +Audio jack)2

Connect the XGA source 2 (for example, a PC) to the INPUT 2 XGA

HD15F connector and its audio to the IN 2 3.5mm mini jack, using separate

cables (as illustrated in Figure 2) or a Kramer C-GMA/GMA cable2

2. Connect up to 2 DVI (that is, DVI-D) sources (for example, computers) to

the 2 DVI-I input connectors, INPUT 1 and INPUT 2, and connect up to 2

unbalanced stereo audio sources to the 2 corresponding AUDIO input

3.5mm mini jacks.

3. Connect the XGA HD15F output connector3to the XGA acceptor (for

example, a monitor) and connect the corresponding AUDIO output

3.5mm mini jack to the unbalanced stereo audio acceptor (for example, an

amplifier and a pair of speakers).

4. Connect the DVI output connector3to the DVI acceptor (for example, a

projector) and connect the corresponding AUDIO output 3.5mm mini

jack of the VS-2DVA to the INPUT 1 3.5mm mini jack of the 903

Personal Stereo Amplifier.

5. Connect4the contact closure remote control PINS (optional), see section 5.1.

6. Connect4the 12V DC power adapter (wall transformer) to the 12V DC

socket and connect the transformer to the mains electricity.

1 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

2 Not supplied. The complete list of Kramer cables is on our Web site at http://www.kramerelectronics.com (click “Cables

and Connectors” in the Products section)

3 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

4 The connection is not illustrated in Figure 2

KRAMER: SIMPLE CREATIVE TECHNOLOGY

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 appropriate1REMOTE 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

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

power to 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 inputs1to the corresponding DVI output2,

and one of the two XGA inputs1to 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 lit, press to toggle for separate

selection. The button is now not illuminated

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 lit, 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
