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.
