SIGNAL DESCRIPTION CENTRAL ELECTRONIC MODULE (CEM)
General
All the values given below are between the connections in column 1 and connection #A28 in column 2 (power ground). This applies unless otherwise indicated in the last column.
Note. It is important to connect the breakout box and check the ground terminals before taking readings.
| U= | DC voltage in volts (V) | T = | Time in milliseconds (ms) |
|---|---|---|---|
| U bat = | Battery voltage (V) | F = | Frequency in Hertz (Hz) |
| U low = | Voltage approximately 0 V | % duty | Duty cycle (pulse ratio) as a percentage (%) |

SIGNAL DESCRIPTION
General
| 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 % |
