Video Passthrough
By connecting a second BNC16 Input Cable (available from X-View) to the second XV-SD8 connector it is
possible to daisy-chain the video signals to another device. In this case the video will normally be
terminated on the downstream device; therefore, the inbuilt terminations on the XV- SD8 should be
disabled by removing the links as shown in the following table:
Installing Multiple Cards
Multiple cards can be installed in a system providing a large number of capture channels. Combinations of
XV- capture cards in the same machine are supported by the driver.
To control the order in which the driver uses the cards, it is recommended when installing multiple cards
that the J5 links on the XV-SD8 are configured. The illustration below shows the jumper link settings for up
to 32 cards in a single system. When two cards have the same link settings, their order is determined
by the PCI bus:
