Note:
All plug-in cards are static sensitive and are packed in anti-static material. Please keep the card in its
packaging until you are ready to install.
It is recommended that you do not discard the packing box until you are completely satised with
the VisionAV capture card and it is fully installed and working correctly. We also recommend that you
make a note of the serial number of the card in a prominent place before the card is plugged into the
computer. This should hasten any query should you need to contact our Technical Support
Department. The serial number is displayed on the card itself and the box label.

Installing the Capture Card
You are likely to need a at blade and /or a cross head screwdriver for the installation of the
VisionAV card; it would be useful to have these to hand before you begin.
• Power down the PC (including peripherals), switch o at the mains and disconnect all the cables
connected to the computer, noting the positions for accurate reconnection.
• Remove the PC cover.
• For the VisionAV/F capture cards, locate a vacant PCI Express slot (x4 or higher) on the
motherboard and remove the blanking plate (retain all screws).
• If the VisionAV/H is to be installed in a short form computer, two locations are required. The
VisionAV/H and the Audio Module should be installed adjacent to enable both cards to be connected
together using the ribbon cable supplied. The Audio Module does not require a slot on the mother-
board.
If you are in doubt consult your motherboard documentation to correctly identify a PCI Express slot. If
the card is forced into a 32 or 64 bit PCI or PCI-X slot it will be irreparably damaged when the system is
powered up and the warranty will be void.
• Reconnect all cables to the PC then connect a DVI cable (not supplied) distributing the DVI source
signal to the connector on the VisionAV capture card
• A standard denition signal can be connected to the RCA connector on the VisionAV
• An Audio feed can be connected to the Audio Module via the Audio Breakout Cable
• Power up the PC and commence the software installation
How to Connect Input Sources
The VisionAV/F card has one DVI-I and one RCA (female) connector and one RGB (male) connector on the
Audio Module:
The DVI-I connector supports DVI, HDMI, Component and RGB (VGA) inputs using the supplied adapters
where required.
A DVI input is connected directly into the DVI-I connector which accepts DVI-D (digital) or DVI-A (analog)
inputs:

An HDMI input is connected to the DVI-I connector using the supplied DVI-HDMI Adapter:
A Component input is connected to the DVI-I connector using the supplied DVI-Component Adapter:
An RGB (VGA) input is connected to the DVI-I connector using the supplied DVI-VGA Adapter:
A Standard Denition input is connected directly into the RCA (female) connector on the VisionAV card:
Audio is connected to the Audio Module using the Audio Break Out cable provided:
1 Balanced (XLR) Input Left
2 Balanced (XLR) Input Right
3Unbalanced Input Left
4 Unbalanced Input Right
5Audio Out Left
6Audio Out Right
Installing Multiple Cards
Multiple cards can be installed in a system providing a large number capture channels. Combinations of
Vision capture cards in the same machine are supported by the driver.
In order to control the order in which the driver uses the cards, it is recommended when installing multiple
cards that the J5 links on the VisionAV are congured. The example below shows the jumper link
settings for up to 32 cards in a single system. When two cards share the same link settings, their order is
determined by the PCIe bus.
