Camera/Gimbal Setup Parameters

Hello,
I am trying to set up a camera trigger (Seagull Map2) to a Sony a5000 using a Kakute H7 v1.3. I’ve connected the camera trigger to servo 5 and I have been following the Seagull manual but it suggests using the Camera/Gimbal Setup page on Mission Planner which is currently greyed out for me, not allowing me to select any of the dialogue boxes. I am unsure of which parameters (In the full parameter list) the camera shutter dialogue boxes correspond to. Does anyone happen to know?

Take a look here

In MNT_ options set what you need for gimbal, then you can set i think camera shutter in Servo_ options
