1.2. Test with simulated data
There is a
data-generating program that comes with the Cascade DataHub called
DataSim. You can run
DataSim locally to create data for various connection
scenarios.
- Start the Cascade DataHub if it isn't already running.
Start DataSim using the Windows
menu, or by double clicking the
desktop icon.
Open the DataHub Data Browser by right clicking on the
DataHub system-tray icon
and choosing
from the pop-up
menu.
Select the DataSim domain in
the left-hand pane of the window.
The Data Browser window should fill with simulated
data updating in real time. The four updating data points
are DataSim/Ramp,
DataSim/Sine,
DataSim/Square, and
DataSim/Triangle.
You can click the
More... button
in
DataSim to access
some options for changing the data feed.
Briefly, you can change the Configurable
Options and click the Apply
Changes button to apply them. The
Waveform Parameters and
Update Frequency are all points in
the Cascade DataHub, and the corresponding points change their
values in the Data Browser as you make the changes.
Changing the Domain from
DataSim will yield no results until
custom domains are configured for the DataHub.
Now you are ready to start using the DataHub.connect to Excel or
connect over
a network or the Internet.
