Matrox Pulsar T Grabbing from two genlocked cameras Matrox Pulsar Matrox Pulsar h Grabbing from two non synchronous cameras with different formats 42 Chapter 5 Using multiple Matrox Pulsar boards Number of cameras per board Matrox Pulsar has four software selectable video input channels but only one analog to digital converter Therefore although you can connect uptofour cameras per board you can only grab from one monochrome camera at a time PCI bandwidth requirements Sustained PCI transfers to memory require the use of a high performance PCI core logic chipset such as the Intel 430H X 430V X 430T X 440F X or 440L X If a high performance chipset isused you should not haveany PCI bandwidth problems when transferring two full sized images simultaneously from two Matrox Pulsar boards in real time H owever transferring more than two images simultaneously might result in PCI bandwidth problems When transferring images from three or more Matrox Pulsar boards simultaneously you will haveto reducethe image sizeto avoid reaching the upper limits of the overall available bandwidth Chapter 6 Matrox Pulsar

ISA CARD SLOTS Some computers have a large black ridged heat sink that prevents long boards from using most PCI board slots Matrox Pulsar must not touch this heat sink Therefore choose a slot where the board completely avoids it For digital input you must free up a second slot If you are installing the optional RS 422 digital interface companion board this slot must be an ISA slot If present removethe blank metal plate located at the back of the selected slot Keep the screw at thetop since you will need it to fasten the Matrox Pulsar board Installing Matrox Pulsar 17 5 Beforeyouinstall your board ensurethat the DIP switches are set properly for the display configuration you want to use The default settings which are for a single screen configuration are shown in the illustration below 12 sini OFF ALAIN AI Bs DIP switch settings SW 1 OFF BIOS protected default ON BIOS unprotected SW 2 OFF Pulsar VGA enabled default ON Pulsar VGA disabled See the next section for more details on setting these switches 6 Carefully position M atrox Pulsar over theselected PCI slot as illustrated below PCI BOARD hr RETAINER 0 88 1 1 1 1 1 GUIDES 32 BIT PCI CARD SLOT Notethat Matrox Pulsar has a PCI board retainer attached toit Thisis because most
