5.3.5 Sequencer
The sequencer is used when different exposure settings and illuminations are
needed in a row.
Values to set Description
Sequencer interval Duration of the interval
Exposure start Exposure delay after interval start
Exposure stop Exposure stop related to interval Start
Strobe start Strobe delay after interval start
Strobe stop Strobe stop related to interval Start
PWM frequency Basic duty cycle ( 1 / Hz ) for PWM
PWM change Demodulation results
In the current GenICam implementation, all values have to be entered in tic val-
ues.
1 tic = 15 ns
Every adjustment (times, frequencies) has to be recalculated into tics and done in
tics. See the example below.
When setting “Exposure Start” and “Stop” consider ‘read-out-time’ of the sensor. It
has to be within the Sequencer interval.
For physical input and output connections refer to pin-out or specifications or see
example below. After trigger signal all programmed intervals will start. Up to 16
intervals can be programmed.
Sequencer settings can be saved to camera EEPROM.
Example
For demonstration, imagine following task to be done:
Scenario
An object should be inspected with a monochrome camera. For accentuating dif-
ferent aspects of the image, 4 images should be taken in a row with 4 different col-
ours of light: Red, Green, Blue, White. White light should be generated from the
RGB lights being activated at the same time. Basis is a dark environment without
other light sources.
Camera wiring
l
3 LED lights are physically connected to the camera on out 0-2 (red, green,
blue)
l
Out 3 is not used
