Signal Specification, Rear Seat Entertainment Module (RSE), Generation 4.3

All the values listed are measured between the terminal in column 1 and terminal #A8 (ground), unless otherwise indicated in brackets.

U= DC voltage in volts (V) UAC = AC voltage in volts (V)
Ubat = Battery voltage (V) f = Frequency in Hertz (Hz)
Ulow = Voltage approximately 0 V t = Time in seconds
PWM = Pulse width modulated signal as a % - -
