5.2.2 Transaction-Level Decoding

Transaction-level decoding presents a higher-level analysis of 1394 data. There are several
ways to activate transaction-level decoding in FireInspector:

• Click on the button for the desired decoding level on the View Level toolbar.

• Use the General tab of the Display Options dialog to set the Trace Viewing Level.

• Select the desired transaction decoding level from the View menu.

• Use the Trace View menu (described on page 79) to set the view level.

Selecting a transaction decoding level causes FireInspector to look for the selected type of
transaction in the Trace. If any are found, they are decoded and displayed.

Transactions are made of one or more packets. FireInspector displays transactions in order
of initiation, meaning that the transaction that begins first in a recording is shown nearest
the top of the Trace. The transaction that begins second is next, then the one that begins
third, and so on. The order is determined by the position of the transaction's starting packet;
the position of the transaction's last packet is irrelevant to the order. Therefore, the packets,
or subactions, that make up a transaction will not necessarily be numbered consecutively.

Transaction Number Field

The first field for all transaction-level rows in a Trace is the transaction number field. It
contains the transaction protocol name and the transaction number.

Expanding and Collapsing Transaction Rows

Transaction rows can be expanded and collapsed in order to show or hide lower transaction
levels and packets. Rows are initially collapsed by default. There are several ways to expand
and collapse the rows:

• Left-click the arrow in the upper left-hand corner of the transaction number field for the

row you want to expand or collapse. You can expand or collapse all transactions of the
same protocol by left-clicking on the arrow and long-clicking — holding down the
mouse button for about 1 second.
