Abstract: A system having a data bus, bus controller(s), remote terminal(s) and a logger. The data bus has an inverted differential line and a non-inverted differential line. The bus controller(s) are electrically coupled to the data bus. The remote terminal(s) are electrically coupled to the data bus. The logger has a bus transceiver and a controller. The bus transceiver is electrically coupled to the data bus. The controller is electrically coupled to the transceiver. The controller is configured to: capture a non-inverted data stream from the bus transceiver, capture an inverted data stream from the bus transceiver, convert the non-inverted data stream into non-inverted packets having a packet size, convert the inverted data stream into inverted packets having the packet size; and write the non-inverted data packets and inverted data packets to a non-volatile memory.

Abstract: A system having a bus controller, a remote terminal, and a message filter, with the message filter having a first transceiver, a second transceiver, and a message processor. The first transceiver is electrically coupled to the bus controller by a first data bus. The second transceiver is electrically coupled to the remote terminal by a second data bus. The message processor is configured to: receive a message from the first transceiver, the message comprising a command word, begin transmission of the message by the second transceiver, extract a destination address from the command word, and stop the transmission of the message when the destination address does not match at least one determined destination address.
