8. Reading a CATC Trace
8.1 Trace View Features
• The Merlin II packet view display makes extensive use of color and graphics
to fully document the captured traffic.
• Packets are shown on separate rows, with their individual fields both labeled
and color coded.
• Packets are numbered (sequentially, as recorded), time-stamped, and
highlighted to show the device status (master or slave).
• Display formats can be named and saved for later use.
• Pop-up Tool Tips annotate packet fields with detailed information about their
contents.
• Data fields can be collapsed to occupy minimal space in the display (which can
in turn be zoomed in and out to optimize screen utilization).
• The display software can operate independent of the hardware and so can
function as a stand-alone Trace Viewer that may be freely distributed.

BTTracer display. Packet #0 is described from left to right:
