Installing the Capture Card
You are likely to need a at blade and /or a cross head screwdriver for the installation of the
VisionSC-SDI4 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 re-connection
• Remove the PC cover
• Locate a vacant PCI Express slot (x4 or higher) on the motherboard and remove the blanking plate
(retain all screws) 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
• Power up the PC and commence the software installation
How to Connect Input Sources
The VisionSC-SDI4 card has four BNC type connectors for four separate, simultaneous inputs. The
connectors have green LED’s. Connect the cables distributing the video source signal to BNC input
connectors on the VisionSC-SDI4 capture card.

When connecting BNC cables, ensure connectors are fully twisted and locked in place. Failure to lock the
connector can result in the BNC cable becoming separated from the card and the connection being lost.

Cable Lengths
The VisionSC-SDI4 supports cable lengths of up to 150m for 3G-SDI. This gure is based on using low loss
coax cables (Belden 1694A). Avoid tight loops or kinks in the cables.
