Power
P = duty cycle * U
D
* I
The duty cycle is a coefficient < 1, which defines the power of the resistor. It is the ratio
of the time period while current flows compared to the total time. If the current always
flows, "P = U * I" will be the determining factor. If the current only flows a hundredth of
time (duty cycle 1 %), a resistor with a hundredth of power will be enough.
NOTE
For the connected LEDs and the ground of the external power
supply, you have to use the ground of the camera at pin 2.

WARNING
The series resistor has to handle the power, which depends on the
duty cycle and the frequency.
Example circuit 3: Controlling a motorized lens
It is possible to control a motorized lens. However, an external micro relay is necessary
which changes the polarity of the lens slider when triggered by the camera's digital out-
put. The following figure shows an example circuit:
