Enabling and Polarity of IO Signals
The polarity of the input and output signals indicating their active
states is selectable (positive or negative logic).
The polarity of level-sensitive signals can be set to High (positive
logic) or Low (negative logic).
The polarity of edge-sensitive signals can be set to Rising (positive
logic) or Falling (negative logic).
Detailed Explanation for Status Expos SMA #4 Signal Timing
Setting in pco.camware:
There are four different signal types selectable. The example timing
diagram shows all four different possibilities:
• Shows the exposure time of the first line
• Shows when all sensor lines are exposed
• Shows the exposure time of the last line
• Shows if any sensor line is integrating
