5.6 Getting Started
Before a profile can be started the software must be configured. Make sure
that the data acquisition device (DAQ) and chiller are connected and
powered up. Then select the Tools > Options menu item to display the
Options dialog.
5.6.1 Selecting a Digital Certificate
First, a digital certificate must be selected. Cryopilot uses a digital certificate
to guarantee the authenticity and integrity of saved data files. The Certifica-
tes tab shows a list of available certificates. It is ideal to use a certificate
issued by a trusted certification authority (CA). If your information techno-
logy (IT) organization already has a digital certificate infrastructure establis-
hed then they may be able to provide a certificate for use with Cryopilot.
In the event that you do not have a certificate to use with Cryopilot, you can
create what is known as a self-signed certificate. "Self-signed" means that
the person who creates the certificate also vouches for its legitimacy. For
Click the Create button, and then click the Yes button on the dialog that
appears. The newly created certificate will be shown in the list of available
certificates.
5.6.2 Configuring Hardware
Next, the hardware must be selected. The Hardware tab contains settings
for common hardware configurations. The most common arrangement
consists of a data acquisition device (DAQ), a chiller, and a shaker. In most
cases the hardware will be detected automatically.
If you will not be running any processes and will only be using Cryopilot to
review data files, then select "None" for all Data Acquisition, Chiller, and
Shaker.
To save the options, click OK.
5.6.3 Program Flow
When Cryopilot software is launched, a splash screen appears briefly and
then the main window is displayed.
At this point the software is idle and will not do anything until the user starts
a process.
To start a process, select the Process > Start menu item or click the Start
Process button on the toolbar. The Start Process dialog will be displayed.
Once the user clicks OK, the software attempts to connect to the data
acquisition device, the shaker, and the chiller, if configured. If any of these
devices is configured but not connected then the user is prompted to check
connections and retry or cancel.
Once a process is started, the temperature chart and the legend are recon-
figured to display the appropriate plots, communications are established
with the chiller, and the data acquisition device (DAQ) is initialized. Once in-
itialization is complete, the initialization message disappears and first set of
data points is plotted. Subsequent data points are displayed at the sampling
interval, which is fixed at 15 seconds.
