Protocol adapter for transferring diagnostic signals between in-vehicle networks and a computer
First Claim
1. A circuit board having quick-start data logging capability and is functional with a protocol adapter for providing communication between a vehicle network and a host computer in one or more of a plurality of protocols, said circuit board comprising:
- a removable circuit board configured to connect between a protocol adapter and a vehicle network;
a circuit of said removable circuit board in communication with a vehicle network and a host computer;
at least one transceiver circuit selectively in electrical communication with said circuit, said at least one transceiver circuit supporting at least one vehicle network protocol;
a volatile memory device in electrical communication with said circuit, such that said volatile memory device is operable to receive data from a vehicle network operating in said vehicle network protocol prior to said protocol adapter and said host computer completing boot up; and
wherein said circuit is operational and begins immediate logging of vehicle network data onto said volatile memory prior to the host computer and the protocol adapter having completed booting up.

Abstract
A protocol adapter for simultaneously communicating with one or more remote computers over any one of a plurality of protocols. The adapter includes a motherboard having an integrated CPU, a plurality of interface modules, a plurality of device drivers and a plurality of daughter-board module slots. The protocol adapter further includes at least one daughter-board interface module mounted in one of the plurality of daughter-board slots. The at least one daughter-board modules expands the number of protocols of the adapter beyond those protocols being run by the motherboard.
