Signal Specification

General

All the values given below are between the terminals stated in column 1 and terminal #A8 in column 2 (power ground). This applies unless otherwise indicated in brackets.

NOTE:

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

U=	DC voltage in volts (V)	U_low =	Voltage approximately 0 V
U_bat =	Battery voltage (V)
