Abstract
A protocol adapter for transferring diagnostic messages between networks within a vehicle and a host computer. The protocol adapter operates as a voltage translator to support J1708 software. The protocol adapter also recognizes when the protocol adapter is connected to a host computer running the J1939 and/or J1708 protocols and automatically switches to that protocol.
Claims35
A protocol adapter for transferring diagnostic messages between one or more vehicle networks and at least one external host computer, said adapter comprising:
- a channel matrix tool for providing communication between said one or more vehicle networks and said at least one external host computer;
- a central processing unit (CPU), said CPU controlling the operation of said channel matrix tool;
- and
- a non-volatile memory for providing storage of data received from said one or more vehicle networks.
A protocol adapter for transferring diagnostic messages between one or more vehicle networks and at least one external host computer, said adapter comprising:
- a channel matrix tool for providing communication between said one or more vehicle networks and said at least one external host computer;
- at least one input channel operable for providing communication between said one or more vehicle networks and said channel matrix tool;
- at least one output channel operable for providing communication between said channel matrix tool and said at least one external host computer;
- a central processing unit (CPU), said CPU controlling the operation of said channel matrix tool;
- and
- a non-volatile memory for providing storage of data received from said one or more vehicle networks, thereby allowing said protocol adapter to provide a streaming data function and record data simultaneously.
A protocol adapter for transferring diagnostic messages between one or more vehicle networks and at least one external host computer, said adapter comprising:
- a channel matrix tool for providing communication between said one or more vehicle networks and said at least one external host computer;
- at least one input channel operable for transferring data from said one or more vehicle networks to said channel matrix tool at one or more bit rates;
- at least one output channel operable for transferring data from said channel matrix tool to said at least one external host computer at said one or more bit rates;
- a central processing unit (CPU), said CPU controlling the operation of said channel matrix tool;
- and
- a non-volatile memory for providing storage of data received from said one or more vehicle networks.
