Chapter 6. Commander
The Commander has four separate functions:
The 'Topology' is used to display the current bus topology with, optionally, more-detailed information
about the nodes. Depending on node capabilities, one can suspend, resume, disable and enable a node.
One can also generate bus resets here and display the new bus topology.
With the 'Phy Register R/W' function, one can read and write the registers of the local and read the
registers of a remote phy interface. The register layout and a list of all register fields are shown.
The 'Memory R/W' function is used to read and/or write the memory of remote nodes. Read, Write and
Lock operations can be performed on a selected set of predefined addresses (like the CSR registers) or
on user-definable addresses.
With the 'Packet S/R' function, one can send all kinds of packets including phy packets, unformatted
packets and erroneous packets to a selected node. Optionally, one can wait for and display the response.
Both the packet sent and the packet received can be displayed as layout or field list.
6.1. How to use it
You can open the Commander by clicking on the Commander button in the main window, or select the
Commander from the 'Analyzer' menu at the top of the main window or one of the other open windows.
When you open the Commander, a window as shown below will appear.
The displayed topology will of course depend on the actual IEEE1394 bus configuration the Analyzer is
connected to.
You can select one of the pages depending on the commands you want to perform. We will describe each
page below.
