Desktop Data Acquisition
DataLINK is an on-line general purpose subject worn programmable Data Acquisition System allowing the user to collect both analog and digital data from a wide range of sensors including Biometrics’ Goniometers, Torsiometers, active EMG sensors, Accelerometers, Pinchmeters, Hand Dynamometers and Contact Switches. Examples of other general sensor inputs include load cells, strain gauges, potentiometers, temperature probes and flow meters.
DataLINK has been developed for the diverse needs of researchers for laboratory based data collection and analysis in industrial, medical, and educational settings.
- On Line Data Collection
- Real Time Data Display
- 40 KHz Total Sampling Frequency per DataLINK
- 8, 16, or 24 Analog Channels
- Audible Threshold Alarms
- Readily Synchronizes with Other Systems
Sensors connect to a small, lightweight Subject Unit with both programmable instrumentation amplifiers and power supply responsible for energising the sensors, sampling and converting the inputs into a digital output. The data is transferred from the Subject Unit to the tabletop Base Unit via a RS485 data transfer cable. This cable (type no. R7000) is 7 metres in length but may be specified any length up to 20 metres. The Base Unit connects to the PC using a USB port where the data may readily be stored on disk or passed real time into other applications such as Microsoft Excel or Microsoft Visual Basic using the DLL (dynamic link library). Analog outputs may be obtained using an optional output cable (R2000i) attached to the Base Unit allowing the DataLINK to be interfaced to virtually any analog data recording system.
DataLINK comes with 8 analog inputs, accommodating both single ended voltage inputs and differential voltage inputs, and with 5 digital inputs, and the DataLINK Management Software.
Each input channel is individually controlled and configured within the versatile and easy to use DataLINK Management Software. Options for the analog inputs include selectable gain, selectable sampling frequency, selectable sensor supply voltage, and selectable zero or threshold level and selectable hysterisis level.
