Bus Monitoring

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Bus monitoring is a term used in Flight Test when capturing data from avionics buses and networks in data acquisition telemetry systems. Typically a bus monitor must listen-only on the bus and intercept a copy of the messages on the bus. In general a bus monitor never transmits on the monitored bus. Once the bus monitor has intercepted a message, the message is made available to the rest of the data acquisition system for subsequent recording and/or analysis. Parser bus monitoring is also known as coherent monitoring or IRIG-106 Chapter 4 monitoring. Parser bus monitors are suited to applications where the bus is highly active and only a few specific parameters of interest must be extracted.
