Time Multiplexing
Time multiplexing allows the Piranha HS 41 to send data to your framegrabber using a
Camera Link Base Configuration. The readout from taps 1 and 2 and taps 3 and 4 are
merged into two time slots. Figure 7 and Figure 8 compare camera readout between the
Medium Configuration and the Base Configuration. Refer to the Camera Link™
Configuration Table on page 49 for more information on tap reconstruction.
