c. After the rotor stops spinning, the cover unlocks and
the lid locked indicator is turned off. The display
reverts to last set parameters.
d. Open the cover and remove samples.
GENERAL: During the run, display shows actual parameters.
To check set parameters, press View button and Select
button. The display will revert temporarily to the set points for
approximately 5 seconds.
Drying Rate
Thermal energy can be applied to the concentrator chamber
to counteract the cooling effect of evaporation, maintain the
samples in the liquid state, and accelerate the concentration
run. Select the highest drying rate if you desire accelerated
drying. To ensure against over drying of samples, and
possible denaturing, it is recommended that the "Heater"
timer be set for only a portion of the total run time (e.g., 50%-
75% of total run time).
Exporting Live Run Data
The unit is equipped with a USB port to enable
communication with an external computer. The USB port is
located on the rear panel of the unit and is connected to a
computer via a standard USB type A to B cable.
CAUTION: USB lead length less than 3 meters
shall be used to connect to the computer
Figure 2. USB Port location
When a run is ongoing, the unit exports the following
information via the USB port every minute.
•
The live temperature applied to the samples chamber
8 |
Operation
•
The remaining heat time for the run ("CCC" indicates
continuous heating)
•
The remaining or elapsed run time, depending on the run
type (manual or automatic)
The data are sent at a fixed baud rate of 115200 and are
comma-separated as shown in the format: <temperature>,
<heat time>, <run time>.
•
The temperature is represented as a 2-digit integer in °C
•
The heat time is expressed as a 3-digit integer in minutes
(or "CCC" for continuous heating)
•
The runtime is expressed as a 3-digit integer in minutes.
In case of a communication failure between the
monitoring program of the computer and the
product, user can re-establish the connection by
disconnecting and reconnecting the USB cable.
Note: The following section details the step-by-step
procedures for configuring Microsoft

HyperTerminal
Configuration
1. Power up the host computer and close any running
applications.
2. Open the HyperTerminal application by clicking on Start \

"HyperTerminal."
3. In the "Connection Description" box, enter the name
"SPD210" and choose an icon and click OK.
4. Connect to the virtual COM port that is linked with the
SpeedVac™ concentrator attached to the computer
(USB virtual com port).
5. In the "COM Port Properties" box \ "Port Settings" folder
select the following options:
Bits per second: _ 115200
Data bits: _ 8
Parity: _ None
Stop bits: _ 1
Flow control _ None
After verifying the above settings, click OK.
6. In the main dialog box click on File \ Save.
