Multiplexing device with provision for expansion
First Claim
1. An adaptive cable for use with a vehicle diagnostic tool, comprising:
- a complex programmable logic device adapted to receive instructions from the vehicle diagnostic tool;
a multiplexer adapted to receive instructions from the complex programmable logic device to configure multiplexer connections for a vehicle communication protocol and for a jump connection of cable pins;
a first cable to connect the adaptive cable to the vehicle diagnostic tool at a first end and to communicate with the complex programmable logic device at a second end;
a second cable to connect to a data link connector in a vehicle at a first end, the first end having the cable pins for the jump connection, and to communicate with the multiplexer at a second end;
a housing that houses the multiplexer, a portion of the first cable, a portion of the second cable, and the complex programmable logic device; and
a plurality of switches on a surface of the first end of the second cable, each of the plurality of switches paired to the corresponding cable pin.

Abstract
An apparatus and method are provided that allow a diagnostic tool to communicate with a data link connector in a vehicle and place the vehicle in a desired state for diagnostic testing. A cable that can automatically multiplex its connections in order to make the appropriate connections between the diagnostic tool and the data link connector based on a communication protocol of the vehicle under test. A connector allowing for selective switching of pins of the connector to jump connect the selected pins. This allows the vehicle to be placed in the proper state for diagnostic testing and the diagnostic tool to communicate with the data link connector regardless of the pins being used by the communication protocol of the vehicle.

15. A method of placing a vehicle in a desired state diagnostic testing, comprising the steps of:
-
receiving a communication protocol instruction from a diagnostic tool via a first cable of an adaptive device having a complex programmable logic device and a multiplexer; sending configuration instructions from the complex programmable logic device to the multiplexer, wherein the multiplexer configures its connections based on the communication protocol instructions; providing communication between the diagnostic tool and a data link connector with a communication protocol module, and the multiplexer via a second cable connected to the data link connector; and providing a connection between connector pins on the data link connector of the vehicle to place the vehicle in the desired state. - View Dependent Claims (16, 17, 18, 19, 20)
