Overview

3 Overview
The Kramer VA-1DVIN is a unique DVI EDID emulator, with a DVI-D
input and DVI-D output on DVI-I connectors
1
. When connecting the
VA-1DVIN to a display device and pressing the CAPTURE EDID button,
the VA-1DVIN reads and stores the EDID (Extended Display Identification
Data) from the display device
2
. For example, when the DVI signal is
extended more than 100 meters over fiber optic cable, the VA-1DVIN can
emulate the EDID information
3
. The display can be disconnected and later
reconnected, without rebooting the operating system.
Note: The VA-1DVIN does not work with HDMI devices.
In addition, the VA-1DVIN:
Features a maximum data rate of 3.3Gbps
Is housed in a Pico TOOLS enclosure
4
Is fed from a 5V DC power supply
Note that only the digital signal (DVI-D) is available on the DVI connector
To achieve the best performance:
Connect 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)
Avoid interference from neighboring electrical appliances and
position your Kramer VA-1DVIN 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
5
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 Note that only the digital signal (DVI-D) is available on the DVI connector
2 The computer needs to have the EDID information available when it boots up, otherwise the DVI output will be disabled
3 The DDC (Digital Display Channel) cable has no effect for distances over 100 meters
4 Four units can be rack mounted side-by-side in a 1U rack space with the optional RK-4PT rack adapter
5 For example, part number 2535-052002

3.1 Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure,
provided by a display, to describe its capabilities to a graphics card (that is
connected to the display’s source). The EDID enables the source (for
example, a PC) to “know” what kind of monitor is connected to the output.
The EDID includes the manufacturer’s name, the product type, the timing
data supported by the display, the display size, luminance data and (for
digital displays only) the pixel mapping data.

5 Connecting the VA-1DVIN Virtual EDID
In the example illustrated in Figure 2, a projector is disconnected from a PC
in order to reinstall it at a distance, after the PC has read the projector’s
acquired EDID from the VA-1DVIN. The projector is then reconnected,
without the need to reboot the system.
The configuration illustrated in Figure 3 requires two separate stages:
The VA-1DVIN needs to acquire the projector’s EDID
information (see section 5.1)
The PC is connected to the VA-1DVIN, letting it read the
projector’s EDID information even if it is not connected to the PC
(see section 5.2).
The projector can now be reconnected at a distance to the PC via
the VA-1DVIN
5.1 Acquiring the EDID
To use the VA-1DVIN to acquire the EDID information, as illustrated in
the example in Figure 2, do the following:
1. Connect the OUTPUT DVI connector to the input DVI connector of the
display (for example, a projector), using a short cable.
2. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity
1
(not shown in this illustration).
The ON LED should light.
3. Press the CAPTURE EDID button.
The ON LED turns off while the EDID information is read and stored in the
VA-1DVIN non-volatile memory. When the ON LED lights again, the
EDID is stored.
4. Disconnect the projector’s DVI connector from the OUTPUT DVI on the
VA-1DVIN.
5. Disconnect the power source.
1 Also make sure that the projector is connected to the power supply

5.2 Reconnecting the Projector
To reconnect the projector at a distance from the PC, as illustrated in the
example in Figure 3, do the following
1
:
1. Connect a DVI source (for example, a DVI computer graphics source) to
the INPUT DVI connector on the VA-1DVIN.
Turn on the DVI source only after connecting the VA-1DVIN, so it can acquire
the EDID properly
2. If required
2
, connect the 5V DC power adapter to the power socket and
connect the adapter to the mains electricity.
3. When installation is complete
3
, connect the OUTPUT DVI connector of the
VA-1DVIN to the projector, using the required cable length.
1 Switch OFF the power on each device before connecting it to your VA-1DVIN
2 Usually, the PC can supply power to the unit
3 The EDID is transmitted to the PC via the VA-1DVIN, so the PC gets the EDID information even if the projector is
temporarily disconnected. When installing the display again at a distance, there is no need to reboot the PC
