Signal Specification

All the values given below are between the respective terminal in column 1 and terminal #C1-2 in column 2 (power ground) unless otherwise stated in parenthesis after the table entry.

NOTE:

It is important to connect the breakout box and check the ground connections before starting to measure.

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 in % % duty = Duty cycle (pulse ratio) in percent (%)
