<p>A method and apparatus for monitoring a data bus which transfers digital information and commands between components of a system wherein the bus operates according to a designated protocol and is of the serial, asynchronous type employing Manchester encoding. A bus interface (22) provides communication with the bus for receiving and processing message data from the bus, and a storage interface (24) provides communication with an external mass storage device such as a hard disk (56) and also stores an operational program for the data bus recorder. A processor (26) connected to both interfaces receives information from the storage interface (24) which defines message collection via a configuration file. A user operated control unit (14) selectively connected to the procesor (26). A personal computer (70) is utilized to specify the configuration file on the mass storage device (56).</p> |
