Safety Instructions
To prevent damage to your Datapath product or injury to personnel operating the equipment, please
read the following safety precautions prior to operation. These instructions should be made available to
all those who will use and operate Datapath products.
Power Supply
All Datapath products require a mains power supply. This power supply must be disconnected when
equipment is being upgraded or relocated.
Do not expose cables to any liquids; doing so may cause a short circuit which could damage the
equipment. Do not place heavy objects on top of any cables as this can cause damage and possibly lead
to exposed live wires.
All computer equipment should be located in a well ventilated area. All ventilation holes on the computer casing must be kept clear of any obstruction at all times. Failure to do so will result in the system over
heating and damaging your equipment.
Working Environment
The equipment should be located in an environment free from dust, moisture and extreme changes
in temperature and should be placed on a stable and solid work surface. Liquids (hot/cold drinks etc)
should not be placed near the equipment as spillage could cause serious damage.
Gas/Flammable Liquids
Electronic equipment should never be used in the presence of gas or any flammable liquid, doing so
could result in an explosion or serious fire.
Smoke/Unusual Smells
Should you notice smoke or unusual smells being emitted from your computer, turn off and unplug the
system from the mains supply. The system should then be passed to a qualified technician for
inspection. Continued operation could result in personal injury and damage to property.
Maintenance should only be carried out by competent technicians, any Datapath plug-in cards that are
physically damaged should be returned to Datapath for repair using Datapath RMA procedures.
At the end of life all Datapath products should be disposed of as per local laws and regulations dictate.
In UK contact Datapath to arrange disposal. Our WEE registration number is WEEE/AA0005ZR.

Your packing box should contain the following items:
The VisionSDI2
Installation CD ROM
If there are any discrepancies, you should contact Datapath immediately.
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 satisfied with the
VisionSDI2 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 flat blade and a Phillips head screwdriver for the installation of the capture card; it
would be useful to have these to hand before you begin.
Installing the card is a simple process, follow the steps below to be up and running in a few minutes:
Power down the PC (including peripherals), switch off at the mains and disconnect all the cables
connected to the computer, noting the positions for accurate reconnection. Remove the PC cover
Locate a vacant PCIe (x4 or above) slot for the VisionSDI2 on the motherboard and remove the backing
plate (retain all screws) If in doubt consult your motherboard documentation to correctly
identify a PCIe (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.
Remove the card from its packaging and secure it firmly into the empty PCIe slot. Extreme care
should be taken when securing the card into the slot as some motherboards may have
components that impede the siting of the card
Screw the card bracket to the back panel of the PC and replace the cover
Re-connect all cables to the PC
Connect the cable(s) distributing the signals to the connectors on the VisionSDI2 card located on the
back panel.
Power up the PC and commence the software installation.
The VisionSDI2 card has four BNC type connectors for two separate, simultaneous inputs and two Loop
Through outputs. The connectors are identified by coloured LED’s; green for input and blue for Loop
Through outputs:
Supported Formats
The VisionSDI2 card supports the following formats:
SD-SDI (480i/576i)
HD-SDI (up to 1080i)
3G-SDI (upto 1080p)
Cable Length
The VisionSDI2 supports cable lengths of up to 150m for 3G-SDI and 300m for SD-SDI. These figures are
based on using low loss co-ax cables (Belden 1694A).
Installing Multiple Cards
Multiple cards can be installed in a system providing a large number of 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 J6 links on the VisionSDI2 are configured. 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 PCI bus.
If you change the link ordering after installation you must run dplinks.exe. This program will update the
existing input names used by the windows DirectShow interface.
To run the dplinks program open the Run by clicking on Start/Run and type dplinks and then press Enter.
The program will run, however no notifications are displayed.
Firmware Upgrades
The VisionSDI2 cards allow firmware upgrade to be completed on site rather than returning the card to
Datapath. Whenever a firmware upgrade is performed, LK1 MUST BE FITTED on the VisionSDI2.
To perform the upgrade, follow the step-by-step instructions provided by the upgrade application.
In the unlikely event that something goes wrong during the upgrade process (e.g. System power outage)
it is possible to revert to the factory settings by powering down the system, temporarily removing LK1
then powering up the system with the link removed. Once the system has rebooted, replace the LK1 link
(whilst the system is powered up) and restart the firmware upgrade process.
It should be noted that the latest driver installation program includes an automatic firmware update, if
required. Therefore, prior to installing the application and driver, ensure that LK1 is fitted.
Software Installation
The Vision software (driver and application) is installed by inserting the CD that was shipped with your
card into your CD ROM drive. The installation process should start automatically.
Should the CD fail to autorun use Explorer to browse the CD, locate then double click on install.exe
file e.g. d:/install.exe and click on Install Software… and follow the installation wizard instructions as

Using the card with other Datapath products
The VisionSDI2 captures data and stores it in an on-board video buffer. This data is then copied using
DMA to the host system for display, storage or streaming.
When a Datapath graphics card is used, VisionSDI2 transfers the data directly to the graphics card thereby
increasing performance. The VisionSDI2 sends the relevant portions of each captured image to each
display channel and instructs each channel to use its graphics engine to render the data. This fully utilises
the hardware and dramatically increases performance.
When a Direct3D compatible graphics card is used the data can be transferred direct to the graphics card
in a similar manner to the Datapath graphics card with the same benefit of non-tearing captures.
When the data is displayed on a non Datapath graphics card, the VisionSDI2 sends the data to system
memory or direct to the graphics card, dependant on the software used for display.
