Gateway Overview

The WSDA-2000 is a data acquisition gateway designed to configure, co-ordinate, and collect sensor

data from LORD Sensing wireless sensor nodes. The gateway supports all data acquisition sessions

between wireless nodes and host computers including: continuous sampling, burst sampling, and

datalogging. The gateway also facilitates precision sampling synchronization between sensor nodes by

transmitting a continuous, system-wide timing reference known as the beacon. Communication between

the nodes and gateway is wireless and uses the LORD Sensing LXRS and LXRS+ data communications

protocols.

The WSDA-2000 utilizes Ethernet and USB interfaces to transfer data from the wireless nodes to a host

computer for viewing, analysis, and storage. It also provides a CAN data ouput.
