Feature description 57
6.3.5 Strobe Control
The SVCam 4I/O concept contains an integrated strobe controller. Its
controls are integrated into the GenICam tree. With LED lights attached
to the outputs, this enables the user to control the light without external
devices. Being controlled via GenICam, any GenICam-compliant 3
rd
party software is able to control the light as well. Depending on the
camera model, up to 4 (see
specifications ) independent channels are
supported with a peak current of max 1 Amp.

Shunt resistors are used to limit the LED current. Make sure, neither shunt
nor LED are run above specs.

USE RIGHT DIMENSION OF RESISTOR!
To avoid destruction of your LED light or camera, make sure to
use the right dimension of shunt resistor. If not done so, LEDs
and/or Camera might be damaged
