<long_desc>Selects which FMU pin is used (range: AUX1-AUX6 on Pixhawk controllers with an I/O board, MAIN1-MAIN6 on controllers without an I/O board. The PWM interface takes two pins per camera, while relay triggers on every pin individually. Example: Value 56 would trigger on pins 5 and 6. For GPIO mode Pin 6 will be triggered followed by 5. With a value of 65 pin 5 will be triggered followed by 6. Pins may be non contiguous. I.E. 16 or 61. In GPIO mode the delay pin to pin is < .2 uS.</long_desc>
