1. A protocol adapter for transferring diagnostic messages between two or more vehicle networks and at least one external host computer, said adapter comprising:
- a channel matrix tool for providing communication of diagnostic messages that are any signals for monitoring a vehicle network within the vehicle for diagnostics and maintenance purposes, said communication occurs between said two or more vehicle networks and said at least one external host computer, wherein the channel matrix tool includes custom routing configurations that are configured via a serial interface with use of a software program that allows the channel matrix tool to communicate with both the external host computer and the two or more vehicle networks;
one or more output ports of the channel matrix tool, said one or more output ports are used as triggers based on receiving a specific message;
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 two or more vehicle networks.

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.
