Notes
If you use this mode, the external ports must be connected with the internal
function using the IO Configurator of CST.

Line trigger mode (Const. int. time)
The following two modes are available:
Line trigger mode:
With the line trigger, the camera sends one line per pulse:
Encoder mode:
The camera measures the distance of the signals and sends lines with the requested
resolution. An internal line trigger is generated. The desired transport and encoder
resolution must be specified in CST.
NOTE
Minimum pulse duration of the line trigger or encoder has to be 5 pulses of the
internal pixel clock of 85 MHz. Minimum pulse duration is 60ns. Otherwise, the
pulse might be ignored due to debouncing within the camera.
Minimum speed with encoder mode is:
V,min = mm/Encoder pulse
0,789s
Example for the required minimum speed with encoder mode:
Encoder has 12,5 pulses per mm
1 Encoder pulse is 1/12,5mm = 0,08mm
V, min = 0,08mm/0,789s = 0,101mm/s
