Overview of /eld_devices
An ELD Device object represents the actual hardware device used to record data from engine and other sensors. Once the ELD Device record is assigned to a vehicle, all data recorded after the assignment is attributed to the specific vehicle. If the ELD Device record is reassigned to a different vehicle, the data recorded after the reassignment is attributed to the new vehicle.
Recording data
Assign an ELD device record to a Vehicle record before using the hardware; otherwise, the data will not be attributed to the specific vehicle.
