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) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | % duty | Duty cycle (pulse ratio) as a percentage (%) |
