DataLITE is a wireless data acquisition system allowing total freedom of movement, with 24 analogue and 12 digital channels for recording data from the range of DataLITE wireless sensors.

DataLITE ADVANCE is the latest addition to the DataLITE wireless sensor range of research and engineering products. It is a desktop unit incorporating all the same features of DataLITE with the addition of analogue outputs for each channel of wireless data. This standard analogue output is easy to interface to and provides the user with a very simple, accurate and robust way of sending data to 3rd party systems.

  • 24 analogue and 12 digital sensor outputs
  • Transfer DataLITE sensor data to 3rd party instrumentation such as video motion captures e.g. Vicon, Qualisys, and Peak Performance
  • Known exact latency of 100 mS delay to a 3rd party instrument
  • Additionally, once configured, DataLITE ADVANCE may be disconnected from the PC, allowing it to be used solely as an analogue output unit. This provides a very robust, novel product which may be used independent of the PC

DataLITE utilises a small transceiver for communications between DataLITE software and sensors. When used with a Windows 10 Tablet, the researcher can monitor and analyse data in real-time while the subject has total freedom of movement in laboratory or field studies.

  • Communicates with up to 24 channels of DataLITE sensors
  • DataLITE sensors typically have 11 hours of continuous use between charging
  • A typical work environment will give up to a 40m working range
  • Several DataLITE systems may be set up in the same working environment
  • Available as a medical or non-medical device with a two-year warranty

DataLITE Performance

DataLITE uses progressive frequency hopping, error detection and data recovery algorithms. This allows the readings to be smooth and robust even in the typical modern work environment which utilises many different types of Wi-Fi products.

Communications between a DataLITE interface and sensors use 4 frequencies out of a possible 32; these are evenly spaced in the range of 2.403 GHz to 2.480 GHz.

DataLITE wireless sensors convert input signals such as joint angle, EMG or force data and transmits in real-time to the PC for analysis. This produces a versatile and expandable design with the greatest possible accuracy, negligible drift and the greatest freedom for the test subject.

RF Channel Optimisation Test

A new RF Channel Optimisation Test is an easy way to detect errors on all 32 frequencies available to DataLITE and determine the optimum combination of RF Channels to use.

DataLITE communications use 4 frequencies out of a possible 32 within the range of 2.403GHz to 2.480GHz; the choice of 'RF Channel' number selects which 4 to use.

Because this frequency range is also used by many other devices, such as Wi-Fi and mobile phones, there is a good chance that if the distance between the Dongle and associated sensors is significant, some communications will be lost due to another device transmitting on the same frequency. DataLITE devices reduce the effect of interference by continuously frequency hopping between 4 frequencies using built in error detection and data recovery.

The RF Channel test performs multiple transmissions of data on all available frequencies in sequence without using any error correction. A result of 100% means that all data transmissions on that frequency have been successfully transmitted and received. The ideal 'RF Channel' to use would be one where all 4 frequencies used by that RF Channel are 100%.
