Niwa Data Radio - Tait TM8105 (Custom)

Product Features
 
  • Niwa Data Radio - Tait TM8105 (Custom) uses this data radio extensively throughout the National Hydrometric Network for telemetering water level data.
  • This 25W, 24-channel data radio is proving to be a robust performer.
  • It's custom-engineered 3DK intelligent interface system enables the intelligent transmission of data at 1200 Baud.
  • It uses a 'one request-to-many' approach to achieve a superior throughput for this Baud rate.
  • The system is configured  for use with NIWA's Flosys software.






Niwa Modbus to SDI converter - Unidata 6543A

Product Features
 
  • Niwa Modbus to SDI converter - Unidata 6543A sometimes referred to as ‘BabelStar’
  • Alternatively it can convert High Speed Serial data to Modbus data.
  • A standard protocol that defines exactly how a sensor must communicate with a datalogger.
  •  HSIO is a Unidata proprietary protocol.
  • In the Modbus to SDI-12 conversion the protocol converter acts as a Modbus slave on a Modbus Remote Terminal Unit (RTU) bus.
  • On receipt of a Modbus command from the RTU, the 6543 converts it to SDI-12.
  • The SDI-12 command is sent to the SDI device, executed and the SDI response is converted to Modbus protocol and sent to the Modbus RTU. 
  • The data returned is selectable, as either BCD or floating point.






NIWA SDI Diagnostic Tool - NIWA SDI Explorer

Product Features
 
  • A diagnostic tool which turns your PC screen into a ‘window’ that allows you to observe the data traffic on an SDI-12 communications bus.
  • You can even take command yourself and directly interrogate any SDI-12 sensor within the system.
  • An industry standard serial data interface used extensively between low-power environmental monitoring sensors and loggers.
  • NIWA has developed this tiny USB to SDI-12 interface to fill the gap.
  • NIWA SDI Diagnostic Tool - NIWA SDI Explorer provides a simple connection between an SDI-12 serial data bus and a computer with a spare USB port.
  • The application software that comes with it allows you to view SDI-12 serial data and enables you to send SDI-12 commands.
  • In this way you can easily check your sensors, monitor and configure SDI-12 data connections.
