Signal Specification, Parking Assistance Camera (PAC)

GENERAL

U=	DC voltage in volts (V)	U_AC =	AC voltage in volts (V)
U_bat =	Battery voltage (V)	f =	Frequency in Hertz (Hz)
U_low =	Voltage approximately 0 V	t =	Time in seconds
PWM =	Pulse width modulated signal in %	% duty =	Duty cycle (pulse ratio) in percent (%)
