time on a hub.
You may display data from either the most recent collection session or from a previously
saved session.
Datascope window
The Settings panel contains listboxes for selecting the serial hub port number and the maximum
number of the sample “buckets” in the buffer (see
on page 54 for
more information).
The main panel contains 16 rows of data during operation or review - 8 receive data rows and 8
transmit data rows, arrayed in Rx/Tx pairs. Each row contains 16 characters of hexadecimal data
plus the equivalent ASCII characters. Nonprintable ASCII data is displayed as a period (.). Blanks
are written in fields where no valid data exists.
