Electrical Connection of Strobe and GP Out

The electrical connection of the strobe and GP Out of The Imaging Source cameras is Open Drain MOSFET. In very simply words, they work like a switch. Therefore, there is no square wave or other signal to be measured

Please use a pull-up resistor to connect this output to Vcc (max. 24 VDC). Please note that the max drain current is 200 mA

The pin assignment of older cameras can be found in White Papers Trigger and IO.

The pin assignment of the 33U,37U,38U, 33G,37G,38G series can be found in the Technical Reference Manuals at the cameras under "Documentation" tab too.

A sample connection circuit is:

The pin numbers can be different at the camera model you use. The "U out" to "Strobe on off" relation depends on strobe polarity, if available on your camera.
