Figure 14. CrossNet System
The CrossNet system is composed of the following:
•
A PC or other Hub with a Bluetooth Radio
•
Nodes
•
SIO Cables
•
Sensors
Hubs control single or multiple Nodes. Using Bluetooth’s Piconet
capability, multiple Nodes (up to seven) can be accessed simultaneously.
This allows up to 28 channels of data to be streamed to the hub at the
highest data rate. Hubs can support more than seven Nodes through point-
to-point connections.
Softsens® software runs in all hubs and controls, manages, and collects all
data from the nodes. For PCs, Softsens is an ActiveX component that can
be used in multiple development environments.
Nodes are the central part of the CrossNet system. Conditioned analog
signals from the SIOs are converted to digital data in the chosen
engineering units (e.g., psi). Onboard Node memory is used to buffer the
data. This data can be continually streamed across the Bluetooth radio to
the hub or stored in the Node for later readout. Data measurements can be
taken at user-defined intervals.
