button. To get original protocol settings use 'Revert' button.
Below is an example of the Protocol-Settings dialog. In this example you can see the settings for the SBP
protocol .
Mostly the protocol analyzer will need information about the Units inside the nodes that comply to the
protocol. For example the SBP protocol will need to know which nodes contain SBP Units and for these
Units it needs to know the 'Management Agent, 'ORB size' and supported 'Command Set. All this
information can be found in the Configuration ROM of the node. The analyzer will search for
Configuration-ROM reads to find out this information automatically.
Node Specifications
To specify a device on the bus within the recorded data, we use a Node Specification. We can not specify
a device with only one node ID, because the node ID of a device may change after a bus reset. So to fully
specify a device, we will need a node ID for each reset segment.
Reset Segments
With a reset segment we refer that part of a recording where the node IDs do not change. Thus resets are
the boundaries of reset segments. All recorded data, up to the first reset event (reset 1) is called
reset-segment-0. All data up to the next reset (between reset 1 and reset 2) is called reset-segment-1,
etc.
Below we will explain how you can make Node Specifications using reset segments.
Triple Analyzer
Below is an example of the Protocol-Settings dialog for a triple Analyzer. It shows the settings per
Analyzer node. In this example you can see the settings for the
SBP protocol of Analyzer node a. Settings
of the other Analyzer nodes are selected with the control above the Node Specification.
