16.1. Recorder Protocol View
16.1.1. How to use it
To display the IP4 results, select the IP4 tab page in the Protocol View of the Recorder. The Protocol View
can be displayed by selecting it in the 'View' menu of the Recorder.
IMPORTANT:
You will need an IP4-Protocol license key to be able to select this view. However, if you open a Recorder
file that was made with a Analyzer with a valid IP4 license key installed, the Protocol View can be
enabled, even if you do not have a valid IP4 license key yourself. For more information about license
keys,

The IP4-protocol analyzer needs some information from the Configuration ROM of an IP4 device, to be
able to analyze the IP4 transactions and packets corresponding to this device. It also needs to know the
FIFO command address and IP address of the IP4 unit to be able to analyze IP4 data. There are two ways
the analyzer can get this information: automatically or manually.
Automatically finding IP4 information
To make sure the IP4 analyzer finds the IP4 information automatically, you should make sure that a read
of the Configuration ROM and an ARP request (which stands for address-resolution protocol) for the node
id of the unit are recorded. The Configuration-ROM information is normally read after a bus reset. ARP
packets are sent if an IP4 unit wants to communicate with another IP4 unit, but doesn't know the 1394
node id of that unit yet. One way to do this is to (re)connect the IP4 device while the Recorder is recording
data. You should also take care that this recorded information is not removed from the recorder buffer
because of recorder-buffer overflow (cyclic recorder buffer). One way to do this is to stop the recorder
before the cyclic buffer (the buffer part before the trigger position) fills completely, or by generating a
trigger before this part is filled completely (see the Recorder for more information).
Manually inputting IP4 information
If no Configuration-ROM reads or ARP packets are recorded, you will need to input this information
manually. Also if only part of this information can be found automatically, you will need to add information
manually. You can do this in the 'Protocol Settings' dialog. It can be opened by clicking the 'Protocol
Settings' button on the toolbar (see below). This dialog shows information used by the all-protocol
analyzers. It initially shows all information that it found automatically and you can change or add
information manually. See the description of the 'IP4-Protocol Settings' below for more information.
16.1.2. Details
The Protocol View consists of a toolbar on the top, with three parts below it: the 'relations' pane, the
details pane and the 'transactions and packets' pane.
