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 Vision 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 VisionAV-SDI are configured. The example below shows the jumper link settings for up to 32 cards in a single system.
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 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 VisionAV-SDI cards allow firmware upgrade to be completed on site rather than returning the card to Datapath.
