L900 RSTAR ARRAY RADIO SERIES SYSTEM

DESCRIPTION

The RSTAR Array Radio Series uses wireless technology to provide automated data acquisition. A complete RSTAR L900 System uses L900 RSTAR Nodes at the sensor level, deployed in a star topology from a continuously active L900 RSTAR Hub, which consists of an L900 RTU interfaced to a FlexDAQ data logger. The RSTAR Array Radio Series is based on the 900 MHZ, 868 MHz, and 2.4 GHz spread spectrum band (country dependent) with extensive open-country range through use of simple dipole or directional antennae.

A complete RSTAR L900 System is packet-oriented, and consists of slave RSTAR Nodes comprised of sensors and compatible "DT Series" Data Loggers which can accommodate: vibrating wire sensors, potentiometers, MEMS tilt sensors, strain gauge (full bridge) sensors, digitally bussed (DT-BUS) sensors, 4-20 mA sensors, and thermistors. RSTAR also uses a L900 Radio and Antenna kit and a L900 RTU (master) which is a DIN-rail mounted module in the FlexDAQ enclosure. The RSTAR L900 nodes wake from low power and collect data from their attached sensors. This data, which includes RTU node address, address, node serial number, diagnostics, data, and CRC check, is then sent wirelessly as a packet to the L900 RTU. Upon reception to the FlexDAQ, the L900 RTU will issue an ACK signal which may include clock synchronization and rate data.

The L900 RTU stores the data in a temporary register set which is overwritten as new data is received; there is an intermediate data logging function in the RSTAR L900 Node. The data logger within the FlexDAQ has ultimate responsibility for logging data.

Power requirements for a single RSTAR L900 node is one lithium ‘D’ cell. The FlexDAQ can be powered by a solar panel, batteries or AC power.

APPLICATIONS

To allow remote wireless data collection from nodes (sensors) to a data logging hub.

QUICK SPECS

Fully compatible with RST "DT Series" Data Loggers.


Excellent Hub - Node range (up to 14 km in open country).


Ultra-low quiescent power. RSTAR Nodes powered by 1 lithium `D` cell (up to 10 years of life).


Simple star routing - no mesh overhead.


Up to 255 L900 Nodes per FlexDAQ.


Simple network setup: add node serial number to RSTAR Hub, deploy.


Based on proven FlexDAQ experience and technology.


Multiple telemetry options (cell, modem, LAN, radio, satellite).


Data can be accessed at multiple locations via WWW.


Data is protected at all stages by encrypted, error-corrected transmission and storage.


Fully compatible with RST GeoViewer Software.
