Patent ID: 7685307

Claim:
A method of binding a first wireless communication unit of a first telematics system of a first asset to a second wireless communications unit of a second telematics system of a second asset, wherein the first asset and second asset are electrically connected, comprising the steps of: (a) establishing communications between the first wireless communications unit and an other wireless communications unit of an other telematics system on an other asset within communication range of said first asset; (b) sending via the first wireless communications unit to the other communications unit a request for the other telematics system to apply one or more requested power pulses to one or more power lines connected to the other telematics system; (c) receiving said request at said other wireless communications unit; (d) said other wireless telematics system applying the requested power pulses through the one or more power lines connected to said other telematics system; (e) detecting at said first telematics system any pulses applied on said one or more power lines to which the first telematics system is connected electrically to the second telematics system; and (f) if the requested pulses are detected by the first telematics system, thus confirming that the other wireless communications system is the second wireless communications system of the second telematics system that is connected electrically to the first telematics system, binding the first wireless communications unit of the first telematics system to the other wireless communications unit of the other telematics system; wherein said first asset is a trailer and said second asset is a tractor, or said first asset is a tractor and said second asset is a trailer.
