Signal Specification: Notes
NOTE:
It is important to connect the breakout box and check ground terminals before taking readings.
There may be several connections and connectors between the control module and components.
For further information about:
- connecting the breakout box, see "Connecting the breakout box, phone module (PHM)".
- checking the ground terminal, see "Checking the ground terminal, Phone module (PHM)".
| U= | DC voltage in volts (V) | UAC = | AC voltage in volts (V) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | t = | Time in seconds |
| PWM = | Pulse width modulated signal as a % | - | - |
