This section contains fault-finding information, useful if the documentation and videos above haven't been able to help you.
To fault find it is recommended that the problem is isolated to one area first.
To do that use a standard servo, powered at 5volts, to check a PWM channel is working properly
on the RC system. Without a known good servo signal available we cannot proceed.
With this known good signal applied to the left 3 pins, and no camera connected,
moving the stick around should cause flashing on the LEDs.
If not check the servo lead and cabling between RC system and the left pins.
Connect the camera, make sure the connector is fully pressed in, virtually all
cameras will work without any menu or configuration change.
If the unit starts taking pictures like an intervalometer this means power has been applied but the PWM signal (the white or yellow wire on the servo connection) has not been connected.
