To acquire sensor data the following components are needed: 1) user-supplied external sensor
2) IEPE-Link
™
-LXRS
®
wireless sensor node 3) LORD MicroStrain
®
data gateway 4) local or
networked host computer with access to the data acquisition software, such as Node
Commander
®
and SensorCloud™. The selection of sensors, gateways, and software is
application dependent, but the basic interfaces are the same. For a connections overview refer
to
.
Nodes will communicate with any gateway. Gateways with analog outputs can be connected
directly to standalone data acquisition devices for data collection, however system
configuration will still occur through a digital communication interface.
Communication protocols between the gateway and host computer vary depending on which
model gateway is used. For example, the WSDA
®
-Base -10
x
-LXRS
™
gateway utilizes local
serial connections to the host computer, such as RS232 and USB, and interface with the Node
Commander
®
software. The WSDA
®
- 1000 - LXRS
™
gateway utilizes Ethernet
communications and can be used with Node Commander
®
and SensorCloud™. Users can
also write their own programs by utilizing the LORD MicroStrain
®
Wireless Sensors Network
Software Development Kit.
