4 Operation
(Future firmware versions will also allow showing trace windows from VME
and e.g. VSB at the same time, also a 200MHz waveform window with trace
data captured by the TIM200-PB).
Message line
The bottom line of the screen (in inverse video) is used to present simple
messages about the status of the analyzer and guide to the user as to which keys
can be typed etc. This line will also show error messages.
Block Cursor recommended
When using terminals like the VT100 etc., it is recommended to select the
cursor type
Block
for good visibility of the cursor throughout the VBT-325
user interface. If a Line cursor is used, this may be invisible in places like tick-
boxes [ a n d in single-character fields in the event patterns.
Refresh Screen
The screen may be refreshed by typing \ \ (backslash twice). This is useful if .
characters are lost, when you change terminal, etc.
Event Patterns
The Event Patterns window defines the patterns to be loaded into the word
recognizers of the VBT-325. The hardware provides four parallel word
recognizers (separate for the VME part and the VSB/SCSI/P2 part), but the
user may define a larger number of predefined patterns that can easily be taken
into use.
Per default, a list of four user-alterable patterns is provided. They are labelled
VMEO..VME3, when VMEbus is selected, VSBO..VSB3 when VSB is selected
and SCSIO..SCSI3 when SCSI is the selected target bus. In addition, there is an
unalterable pattern called AnyThing, which is always set to "Don't Care" (x). In
the figure below, one user-defined event pattern "Mytrigger" is included.
In the default setup, the most important signals and signal groups are shown in
the Event patterns window. The user may insert additional signals or signal
groups, as well as additional patterns with user-defined labels (instructions are
given below). Vertical or horizontal scrolling takes place when the user moves
the cursor around in the window, to show the part of the patterns that is hidden
outside the window borders.
