Exposure ON: Open drain ON
Exposure OFF: Open drain OFF
Open drain output requires a pull-up resistor for the external circuit. Configure the circuit so that it satisfies the
following formula.
C ≥ A × 1/(B+1)
A: PU power supply voltage (V)
B: PU resistance (kΩ)
C: VIL of the external circuit (V)
FOCUS terminal/TRIGGER terminal (Input)
Focus ON: 0 V
Focus OFF: Open
Trigger ON: 0 V
Trigger OFF: Open
Connect this pin to a switch that can toggle between the open (unconnected) and GND (0 V), or an open drain/open
collector circuit.
