Signal Specification

General 

All values given below are between the terminals stated in column 1 and terminal #B5 (power ground). This applies unless otherwise indicated in brackets.

NOTE:

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

U= DC voltage in volts (V)    
Ubat = Battery voltage (V)    
Ulow = Voltage approximately 0 V
