Figure 11. Connecting Strobe units to a Huygens Optics Camera Interface (Type: HO-CIF2.001 with
2 outputs) using standard strobe cables (HO-STCA.001)
When using the Huygens Optics Camera Interface, the power supply to the units as well as the
trigger pulses from a camera or external source (optical of inductive pick-up element) will be routed
correctly. Always first connect all the cables to the interface
before switching on the power
. For
more information, refer to the Camera Interface manual.
When connecting to a camera, the timing of the camera should be set such that the flash is within
the exposure interval of the camera. This is schematically shown in figure. Make sure that the
positive slope
of the camera’s trigger output is within the exposure interval of the camera.
Otherwise the camera will show a dark or underexposed image.

Connection to other interfaces
The device can also be connected to other camera interfaces. Modern industrial cameras generally
contain (multiple) IO ports that can be used to trigger units such as the CamStrobe. If an optocoupler
output is available, this is the preferred way to connect the camera, since it is less likely that the I/O
port of the camera is damaged. Many direct camera IO ports only allow voltages of 3.3V. Figure 13
shows a typical scheme of how a CamStrobe can be connected to an optocoupler output of the
camera.
