2.6 Conversion Window
The Conversion Window (Figure 4) allows the
user to see the results of single and continu-
ous conversions, perform data averaging, uti-
lize the power-saving modes of the CS5461,
and reset the CS5461’s serial port. The Con-
version Window can be accessed by pulling
down the Menu option, and selecting Conver-
sion Window, or by pressing F3.
2.6.1 Single Conversion Button
On pressing this button, single conversions
will be performed repeatedly until the user
presses the Stop button. After each conver-
sion is complete, the Result data column will
update with the values present in each data
register. The Mean and Standard Deviation
columns will update every N cycles, where N is
the number in the Samples to Average box. It
may can take many collection cycles after
pressing the Stop button before the data actu-
ally stops being collected.
2.6.2 Continuous Conversions Button
This button functions similarly to the Single
Conversion button, except that continuous
conversions are performed instead. The data
on the screen is updated in the same fashion,
and the Stop button terminates this action.
There are some speed limitations when per-
forming this function, and if any of these limita-
tions are exceeded, the user will be prompted
to change some settings before proceeding.
2.6.3 Re-Initialize Serial Port Button
When this button is pressed, the software will
send the synchronization sequence discussed
in the CS5461 data sheet to the part. This se-
quence brings the CS5461’s serial port back to
