The FireInspector analyzer box monitors and records bus activity when connected to any
point in a 1394 tree. It then displays the recorded packets in CATC Trace format.
The analyzer connects to the IEEE 1394 bus topology as an active node and acts as a
repeater to all data and arbitration signals received on the bus. It listens and records relevant
signals on the bus.
The FireInspector analyzer includes provisions for on-the-fly detection of, and triggering
on, numerous events. Such events include specific user-defined bus conditions, PHY
packets, packet header information, data patterns, and abnormal (error) bus conditions.
FireInspector continuously records the bus data in a wrap-around mode.
Upon detecting a triggering event, FireInspector records data up to a specified point.
Real-time event detectors can be individually enabled or disabled to allow triggering on bus
events, as the events happen. This includes predefined exception or error conditions, and a
user-defined set of search conditions. The unit can also be triggered by an externally
supplied signal.
Real-time event detection information is available via an external DB-37 connector, making
many control, timing, and recovered signals available externally. These signals can be
probed and used by other circuitry.
The following sections explain how to set up recording options, how to make a bus traffic
recording, how to reset the 1394 bus, and how to enable or disable Configuration ROM in
FireInspector.
4.1 Recording Options
You can customize the way that bus traffic is recorded using the Recording Options dialog
in FireInspector. These settings can then be saved as a recording options (.rec) file. You can
load saved settings to use them at any time.
To access the Recording Options dialog, do one of the following:
• Click the Recording Options icon on the toolbar.
• Select Setup > Recording Options from the menu bar.
There are three tabs in the Recording Options dialog:
• General: the General tab contains options for generic recording settings.
• Events: the Events tab is used to specify the events that are used on the Actions tab.
• Actions: the Actions tab is used to configure what takes place when specified events
occur.
