Index 2.1
Clear all data from a specified trace, and erase the trace area. As a result, the next Update Trace command
behaves as though it is the very first update after initialization.
Index Byte Index used to identify the desired trace. Specific to Traces.

Index Number
Index Number 2.1
Clear all data from multiple specified traces, and erase the trace areas. As a result, the next update trace
commands behave as though they are the very first updates after initialization.
Index Byte Index used to identify the first desired trace. Specific to Traces.
Number Byte Number of trace entries to be reset.
10.9 List All
Traces Dec

FE 73
þ s
2.1
Read a list of all traces. One entry is provided for each trace, an entry consists of the trace Index and a Value.
Return Message 252 115 Length ID Value
Index Byte Trace index number. One for each entry. 0 signifies an undefined entry.
Value Signed Short Current value of the trace. One for each entry.
10.10 Initialize a

þ t
Index X Y Width Height Min Max Step Style Red Green Blue
Index X Y Width Height Min Max Step Style Red Green Blue
Index X Y Width Height Min Max Step Style Red Green Blue 2.1
Initialize a graph trace for later implementation. Traces defined in the same area with the same step and style can
be updated simultaneously, as a multi-variable graph, using the Update Multiple Traces command. Individual
traces can be updated using the Update a Trace command.
Index Byte Index used to identify the desired trace. Specific to Traces.
X Signed Short Leftmost coordinate of the trace region.
Y Signed Short Topmost coordinate of the trace region.
Width Signed Short Width of the trace region.
Height Signed Short Height of the trace region.
Min Signed Short Value displayed at the lowest point of the trace.
Max Signed Short Value displayed at the highest point of the trace.
Step Byte Number of pixels shifted when a trace is updated.
Style Byte Orientation and Direction of the trace, as per eTraceTypeandDirection values.
A style is created by summing values of individual attributes. For example, a
Line with a Bottom Left origin, Shifting right has a Style value of 129.
Red Byte Intensity of red for trace colour, 0 to 255, limited to display metrics.
Green Byte Intensity of green for trace colour, 0 to 255, limited to display metrics.
Blue Byte Intensity of blue for trace colour, 0 to 255, limited to display metrics.
