Signal Specification

General

All the values given below are between the respective terminal in column 1 and terminal #C1:13 in column 2 (power ground) unless otherwise stated in brackets after the table entry.

NOTE:

It is important to connect the breakout box and check the ground terminals before taking readings.

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 as a %
