1. Data Port Sequencer Multi channel area scan and linescan cameras output image data in a variety of pixel sequences An important PC2 CamLink feature is its ability to transfer images to the host in the normal raster scan format for processing or display Re sequencing is performed in realtime without host processor intervention Typical multi channel image re sequencing consists of reordering odd and even pixel sequences odd or even lines or segmented scans The PC2 CamLink Data Port Sequencer has the ability to promote 10 bit 12 bit and 14 bit pixels to 16 bits It optionally supports truncation to 8 bits for all pixel depths above 8 bits The figures in this section illustrate a variety of multi channel pixel data sequences from linescan and area scan cameras PC2 CamLink can re sequence all situations shown Note The PC2 CamLink only supports re sequencing from left to right and top to bottom Any channel configuration scanning from right to left or from bottom to top is not directly supported and must be re sequenced by software on the host processor 44 e Part I PC2 CamLink Board PC2 CamLink User s Manual Single Channel One channel presents the pixel data in sequential order The acquired sequence represents the original image without need of sorting or reformatting The figure below single channel shows where the data appears in the original image PC2 CamLink can support this format for pixel depths

21. since the PCI bus communication protocol introduces overhead and that other devices are accessing the PCI bus the practical capacity is generally around 60 80MB per second and is highly dependant upon your PCI chipset In general 1 Ifthe required bandwidth is smaller than 60MB per second it should be acceptable for most PC systems available on the marketplace today 2 If the required bandwidth has a range between 60MB per second to 80MB per second precaution must be considered towards the system s chipset quality and towards other PCI devices installed within the same system 3 Bandwidth larger than 80MB per second cannot reliably be handled by PC2 CamLink because of its FIFO based architecture Consider using the DALSA PC CamLink or X64 CL in this case These latter boards provide enough onboard memory to compensate for PCI latencies Because the PC2 CamLink transfer engine is using a 4KB FIFO for transfers when the PC2 CamLink is acquiring and transferring an image simultaneously the FIFO gets filled at the maximum speed during one line period If the line size is smaller than 4KB the line blanking period will allow the FIFO to be emptied However a line size larger than 4KB requires the availability of the PCI bus when the frame grabber transfers an image This leads to two different methods of bandwidth computation required by a particular camera Note The line bandwidth is the limiting factor for both area scan and linescan cam
