7.6.1.5 Pulse Width Modulated Outputs (only VCXG.I/.I.XT)
With the function Pulse Width Modulated Outputs (PWM) it is possible to control an illumi-
nation controller or an illumination directly connected to the camera in various ways. The
set LineSource is used as a signal for the control.
Caution
Erroneous settings can destroy the illumination! The outputs of the camera
are protected against destruction. Please follow the information in the data
sheets for your illumination. Contact the manufacturer of the illumination if
you are unsure about admissible parameters.
Setting a output to a specic illumination
1. Set LinePWMCongurationMode to true
2. Set at LinePWMMaxDutyCycle and LinePWMMaxDuration the
maximum admissible parameters of your illumination (e.g. Falcon
FLDR-i90B-IR24).
LinePWMMaxDutyCycle = 10 %
LinePWMMaxDuration = 10 ms
3. Set LinePWMCongurationMode to false.
→ The values set in step 2 are now the max. admissible parameters.
