With this control you are able to select the protocol analysis result of each supported Analyzer node.
14.2.2. Relations Pane
This pane shows all found transactions and packets, grouped into items and displayed in a tree. The tree
structure indicates the relation between the items. The items are not necessarily recorded in the same
order as displayed in this tree. However, all items inside the same item of the tree (at the same level) are
listed in the same order as the first corresponding packet of each item was recorded. To find out the order
of corresponding transactions and packets, see the 'transactions and packets' pane or take a look at one
of the other views of the Recorder (e.g. the Transactions View).
For each found or manually specified NodeSpec there will be a root item in the tree (NodeSpec 0 above).
For information about NodeSpec's, see 'IIDC-Protocol Settings' below. For each found or manually
specified Unit, there will be a Unit item inside the corresponding NodeSpec (Unit 0 in NodeSpec 0
above).
A black item indicates that it has no corresponding transactions or packets (e.g. NodeSpec and Unit
above). It just is used for proper grouping of the items in the tree. All colored items however correspond to
one or more transactions or packets. When selecting such an item, the details of that item are displayed
in the 'details pane' and the corresponding transactions and packets are highlighted in the 'transactions
and packets' pane (see below). Note that bus resets like '' are also displayed in black, but have a
corresponding item in the 'transactions and packets' pane.
The type of items that can be displayed are:
· Node: displays a 1394 node with IIDC units inside that node below it. Each node gets a logical node id,
which is fixed for the entire recording. This logical node id is called a NodeSpec and is displayed in the
tree.
·
Unit: displays a IIDC unit inside a 1394 node. The tree shows the logical unit number.
· Feature register reads or writes.
· Status and control register reads of writes.
·
Read of inquiry registers.
· Video frame.
· Channel allocation and de-allocation.
·
Bandwidth allocation and de-allocation.
For each item in the tree two extra columns indicate the source and destination NodeSpec ID.
The following color scheme is used for these items:
·
item group
· write of a feature
·
read of a feature
