Appeal No. 2006-2336
Application No. 09/849,916
The software is used to control the capturing
of the appropriate data and to provide that
data as output, according to control inputs
received from a user. As is well known in
the art, when necessary the software is
loaded from the mass storage device 26 to the
main memory 24 for use by the CPU 12. The
software of the present invention controls
the operations and functions of the IEEE 1394
serial bus network data capture and analyzer
device, allowing a user to specify that the
data captured will trigger or begin upon the
occurrence of certain events, such as the
detection of a specific packet header, field
or data pattern, an error, or a specific time
or cycle event. It should also be understood
that the data captured can be triggered off
of any other appropriate event. In order to
capture data triggered off of a specific
event, the software implements specific
capture filters based on the appropriate
trigger event. The capture filters are
implemented on the interface card 20 and
monitor the data passing through the physical
interface 22, between the devices within the
IEEE 1394 serial bus network 46, for the
appropriate data to be captured.
A user interface is also provided on the
display 28 for allowing the user to choose
the trigger events, to select captured data
for display and to provide the captured data
either to the printer 29 or to a media device
such as a floppy disk or magnetic tape,
through the mass storage device 26. Through
the user interface, the keyboard 30 and the
mouse 32, a user can choose specific trigger
events for capturing data which is
transmitted on the IEEE 1394 serial bus
network. The system translates the selected
trigger event into a predetermined sequence
of digital data. Once data is captured, that
data is stored in the internal memory 24 and
displayed under user command, on the user
interface. Through the user interface, the
user can also choose to have the captured
data printed on the printer 29 or saved on
the mass storage device 26.
