Expanded protocol adapter for in-vehicle networks
First Claim
1. A protocol adapter for wirelessly transferring diagnostic signals between a vehicle network and a computer, said protocol adapter comprising:
- said protocol adapter is for transferring diagnostic signals between a vehicle network and a computer that is a lap-top or bench top computer where said protocol adapter is used as a diagnostic tool to bridge the computer to a vehicle network wherein said protocol adapter wirelessly performs ECU fault code interrogation, communication with a remote network, vehicle maintenance status checks or trip performance data downloads, and improved asset control, logistics and inventory management, diagnostic support and maintenance scheduling;
a plurality of electrical circuits and an RS232 bus, said circuits being capable of operating in more than one protocol, said circuits including a voltage translator for translating a voltage so that the protocol adapter operates in a pass-through mode;
a processor contained in the protocol adapter;
a processor memory map of the processor of said protocol adapter having a bank switching feature that is used to increase the amount of usable memory beyond the amount directly addressable by the processor, wherein memory is swapped in and out of the processor memory map to provide for multiple programs to be run on said protocol adapter, wherein said bank switching feature provides for field upgrade capability wherein non-volatile memory is programmed in the field such that new software features are added in the field.

Abstract
A protocol adapter for in-vehicle networks that provides diagnostics, analysis and monitoring. The protocol adapter has a pass-through feature (voltage translator)/smart mode that allows the protocol adapter to emulate older boxes. Visual indicators (LEDs) indicate the pass through feature is in operation. LEDs also indicate activity on the RS232 bus between the adapter and a PC. Single color and multiple color emitting LEDs indicate a program is being executed and identify the program that is being executed. The protocol adapter supports RP1202 and RP1210, J1708 and J1939 and J1939 Transport Layer. The protocol adapter has a Real Time Clock, Standard COMM port connection, 7-32 Volt Supply and is CE compliant. The adapter can be used wirelessly.
