SYNC TRIGGER BUTTON CIRCUIT
The SYNC connector has a 3.3 V Schmitt trigger (5 V tolerant). The trigger is not a switch closure circuit, so it
requires that the trigger source supplies current. Both edges of the input signal may be used as a trigger.
For example, this is the behavior of the circuit when the GPI trigger is used for record start/stop:
 Start Record: On ground to 3.3 V transition
 During Record: Hold at 3.3 V
 Stop Record: On 3.3 V to ground transition
 During Stop: Hold at ground
