초록 ▼

An interface circuit for providing signals necessary to monitor one or more on-board vehicle computers through a serial communication link between an off-board controller and the on-board vehicle computer. The interface circuit is provided on the vehicle in order to provide the command signals to the off-board controller which will enable a standard monitoring device to read key information from the on-board vehicle computer. Additionally, the interface circuit also provides support of a second mode of operation that conforms to a proprietary communications protocol. The interface circuit automatically recognizes and adapts to the proper communication protocol for the tool sensed. The interface circuit complies with both a proprietary communication protocol and with an ISO 1941 format which satisfies an OBDII/CARB specification which all automobiles sold in the United States must comply with by the 1996 model year.

대표청구항 ▼

An interface circuit for automatically providing bi-directional communication with at least one on-board vehicle computer under a plurality of different communication protocols, comprising: bi-directional communication means for enabling communication under a first communication protocol; full duplex communication means for enabling communication under a second communication protocol, said full duplex communication means having a receive bus and a complimentary transmit bus; edge-detect means for distinguishing between identification data and communication data, said edge-detect means having an input; comparator means having a first input for receiving a voltage reference, a second input for receiving a data input and an output coupled to said input of said edge-detect means, said comparator means and edge-detect means changing a mode of communication between said first communication protocol and said second communication protocol; and feedback means coupled to the bi-directional communication means for enabling reception of incoming messages while filtering a local echo of a transmitted message.
