Excessive Engine Speed (Rpm); Vehicle Speed; Vehicle Battery Voltage (Low Battery Warning) - Novatel RTT2211 User Manual

Excessive Engine Speed (RPM)

Excessive engine speed alerts are triggered when the engine speed (in RPM) exceeds a
defined RPM level (in ¼ RPM increments) for a defined period of time in seconds (e.g., 30
seconds).
The MT 3060 has three definable thresholds.
Unnecessary wear and tear on the Powertrain Control Module (PCM) may occur if constant or
frequent excessive engine speed is reported. One of the following situations may cause
excessive engine speed:
Obstructions, such as ice or mud, that may cause wheel slippage if the obstruction is not
l
removed
Revving the RPM while in neutral
l
Speeding or reckless driving that causes excessive RPM engine speed
l
The following AT command example sets the excessive engine speed threshold at 1 to 4000
RPM. Then, if exceeded for 3 seconds, it triggers the input event. This event will clear once
engine RPM is below 4000 for 30 seconds.
AT$OBDEES=1,4000,3,30

Vehicle Speed

A vehicle speed alert is triggered if the device is configured for vehicle speed alerts and the
vehicle moves faster than one of the three configurable thresholds (e.g., 70 MPH).
The following AT Command example sets the vehicle speed threshold at 1 to 112 KPH
(~70MPH). When the threshold is exceeded for 10 seconds, an input event is triggered. This
event will clear when the vehicle speed is reduced to 104KPH (~65MPH).
AT$OBDSPD=1,112,10,104

Vehicle Battery Voltage (Low Battery Warning)

The vehicle battery voltage alert is triggered when the vehicle's battery is reported to be
below a threshold (e.g., 10.8 V) for a user-defined period of time in seconds (e.g., 300
seconds).
The following AT Command example sets the low battery threshold to 10.8 volts. When the
voltage remains below this threshold for 300 seconds (5 minutes), it triggers an input event.
Restoring voltage above the threshold for 300 seconds (5 minutes) will clear this event.
