Appendix B: Installing the Video Capture Cards
B.6.6 Installing Multiple Cards
Multiple cards can be installed in a system providing a large number capture channels. Combinations of Radian
Video Wall Processor capture cards in the same machine are supported by the Radian Video Wall Processor
driver.
To control the order in which the driver uses the cards, we recommend when installing multiple cards that you
configure the J5 links on the VCC-HD-4-H or VCC-HD-4-D. 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.

DirectShow
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, click on Start/Run and type dplinks, and then press Enter.
The program will run, but no notifications are displayed.
