Scheme 1

Scheme 1: Signal Specification

Connector C, terminals #C1-#C2

All values given below are between the terminals stated in column 1 (terminal in the breakout box) and terminal #C2 (ground). This applies unless otherwise indicated in brackets.

Note. It is important to connect the breakout box and check ground terminals before reading off.

U=DC voltage in volts (V)U AC =Alternating current in volts (V)
U bat =Battery voltageF =Frequency in Hertz (Hz)
U low =Voltage approximately 0 V%duty =Duty cycle (pulse ratio) as a percentage (%)
T =Time in milliseconds (ms)
