rS232 output
an rS232 port is available on the Super-Nuova to output
elapsed time and speed data. The data is printed once every
second when the unit is powered on (displays on). a comma
separates each piece of data so that it may easily be import-
ed into a spreadsheet as CSv (Comma Separated values).
The actual data stream sent every second consists of:
elapsed Time, Stirring Setpoint and actual Stirring Speed.
elapsed time is a 1 second counter that rolls over to zero
again every 12 hours (43,200 seconds). The speeds are
given in rpM. When the unit is first powered on (displays
turn on) a header will print indicating the columns.
In order to communicate with the Super-Nuova, the com-
puter connected to it needs to be set with the following
parameters:
• BITS per SeCoND: 57,600
• DaTa BITS: 8
• parITY: NoNe
• STop BITS: 1
• FLoW CoNTroL: NoNe
also, the first time a unit is plugged in, a paragraph of diag-
nostics information will be sent via rS232 and can be viewed
with a terminal program. an example of the data that is sent
is:
Software version: 1.00
Stir Hours: 0
Heat Hours: 0
Calibration Set point: 70
Calibration offset: 0.0
Since there is no heating feature on this unit, Heat Hours will
remain at 0. Stir Hours and Heat Hours are kept internally in 1
minute increments and displayed to the nearest hour. The
Calibration Set point and Calibration offset will also read 0.
