This setting only appears when the Capture Trigger is set to
"BYTE EQUAL" or "BYTE NOT EQUAL".
Use the keypad to enter the byte value (in Hex) that the
selected byte's received value will either need to "equal" or
"not equal" in order to trigger the capture event.
When a Capture event has been triggered, 256 overhead
byte values will be captured (from 0 to 255).
This setting is used to specify how many of those 256 bytes
should be captured immediately following the trigger, and in
turn how many of those 256 bytes should be captured
immediately preceding the trigger.
If 255 is entered (default), then the triggered byte value,
and the following 255 byte values after the trigger event will
be captured.
If 254 is entered (default), then the one byte immediately
preceding the trigger, the triggered byte value, and the
following 254 byte values will be captured.
If 100 is entered, then the 155 bytes immediately
preceding the trigger, as well as the triggered byte value, and
the following 100 byte values will be captured.
