Setting the Parameters Using Direct Register Access
To set the trigger mode for the frame start trigger to on and to select a trigger source via direct
register access:
Set the value of the Trigger Mode Frame Start register to On.
Set the value of the Trigger Source Frame Start register to Software, Line 1, CC1, CC2, or
CC3.
If the trigger source is set to Line 1, set the GPIO line to operate as an input by setting the
value of the Line Mode Line 1 register to Input.
If the trigger source is set to line 1, CC1, CC2, or CC3, set the value of the Trigger Activation
Frame Start register to Rising Edge or Falling Edge.
To set the trigger mode for the frame start trigger to off, set the exposure time, and set the frame
acquisition rate via direct register access:
Set the value of the Trigger Mode Frame Start register to Off.
Set the value of the Exposure Time Raw register as desired.
A value in a raw register is simply an integer value with no units. To determine what the actual
setting will be, you must multiply the value in the raw register by the camera’s time base. The
time base on ace cameras is 1 µs.
For example, if you set the Exposure Time Raw register to 1000, the exposure time would be
1000 µs (1000 x 1 µs = 1000 µs).
Set the value of the Acquisition Frame Period Enable register to 1 (true).
(This will enable the camera’s ability to internally control the frame period.)
Set the value of the Acquisition Frame Period Raw register as desired.
(Frame Rate = 1 /Frame Period.)
