Eletronic schutter cable for cameras
Shoplink: Shuttercable
High-quality cameras (eg SLR, Canon G11, EOS 5D etc.) usually have an input for a remote trigger.
A trigger cable for these cameras can be easily built, which can be controlled by the FlightControl.
A blue LED on the Shuttercable signals the switching process.
Set
The Shuttercable-Set consists of:
- A board with optocouplers and LEDs
- A cable to connect the camera (Set1 = 2,5mm plug / Set2 = N3 plug)
- A two-core cable for connection to the flight control
- Transparent shrink tube
Connect the cable - Set 1 = 2.5mm plug
Strip the cable
Connection
INFO: The kit can be supplied with different cable colors.
Each of the colors in the assignment as follows:

The last booth cables (blue + white) are connected together. So the camera gets the same command to Focus and Shoot.

red cable = In+
black marked cable = In-

Connect to the FlightControl
The red cable is connected to the transistor outputs "Out1" or "Out2" (top row of SV2).
The red wire of the cable is always in the middle.
The outputs Out1 and Out2 can be used.
Trigger
The Shuttercable is connected in this example to "Out2".
The trigger can be controlled as follows:
Adjustable interval after engine start
- set interval and fixed bit pattern
- Here settings for Out2: fixed interval (30)
- Flash patterns is active only when the motors run
Values below 6 and over 220 result in an static signal. If you need a blinking interval, please use values between 6-220
Using switches on the remote control
- Select a potentiometer instead of the interval
- Settings for this Out2: Poti4 assigned

Optocoupler
An optocoupler provides electrical isolation between flight control and camera.
It protects the camera against damage in case of faulty connection or overvoltage.
The optocoupler operates almost like a switch.
