DataLOG

The DataLOG (MWX8) is developed to meet the needs of researchers for portable data collection and monitoring in human performance, sports science, medical research, industrial ergonomics, gait laboratories, and educational settings.

DataLOG can be worn on the arm or leg in addition to the traditional belt/waist placement and incorporates a color graphics LCD, joystick, micro SD card interface, and a real-time Bluetooth® wireless technology link to a PC.

DataLOG is available as a medical or non-medical device

During all stages of the design and development process, attention has been given to the Bluetooth Wireless link, providing real-time data transfer and display. In addition, the data is automatically backed up to the Micro SD card providing complete peace of mind.

  • Latest Generation Fully Programmable Portable Data Collection
  • Real Time Data Display and Analysis
  • 8, 16 or 24 Independent Programmable channels
  • Sampling Rates up to 20 KHz / channel (160 Khz total per DataLOG)
  • Auto Data Backup using Micro SD card
  • State of the art Wireless Bluetooth Technology
  • Dynamic Link Library (dll) for Real Time Data Transfer to Other Applications
  • Readily Synchronizes with 3rd party Systems
  • Full Colour Graphics LCD
  • The DataLOG Management Software may simultaneously control up to 3 DataLOG units, giving the researcher the flexibility of up to 24 independent programmable channels.

Features & Accessories

DataLOG is a general purpose, programmable Data Acquisition Unit allowing the user to collect both analogue and digital data from a wide range of sensors. All Biometrics Ltd sensors readily connect to the DataLOG including:

Data recording options include:

  • display and analyze real time within the PC using Bluetooth
  • store on the PC and auto-back-up to the Micro SD card
  • store data to the Micro SD card for later download
  • transfer data real time using the Dynamic Link Library into 3rd party programs using tools such as MS Visual Basic or Visual C++
  • store as ASCII or as a standard Sound Wave file for passing into other applications such as Microsoft Excel or Cool Edit
  • display real time on the DataLOG Graphics Display in engineering units, or as a bar chart, or as adjustable audible alarms
  • manual start with pre-set automatic stop
  • remote record start/stop by TTL signal sent from other instrumentation to the DataLOG (via included SYNC1 Cable) i.e. DataLOG is a slave
  • start/stop other instrumentation by TTL signal sent from the DataLOG (via included SYNC5 Cable) i.e. DataLOG is the master

The front end amplifier configuration and sensor power supply are programmable enabling the researcher to also connect a wide range of general or custom transducers including:

  • General Load cells
  • Strain gauge devices
  • Single ended voltage inputs
  • Differential voltage inputs
  • Temperature probes
  • Flow meters
  • Microphones

The DataLOG is configured from the host PC using the Bluetooth wireless link, including simple adjustments per channel for gain, power supply, sampling rate and datum settings. When Biometrics' sensors are connected these parameters are automatically set using a drop down menu.

After configuring from the PC, many operations are carried out using the DataLOG LCD and menu system. The screens are selected by scrolling left or right using the navigation joystick.

Event Markers

These useful accessories allow time marks to be registered in the recorded data. The events are marked for the duration of the time the switch is pressed:

  • IS3 - A 1.8 meter cable with a suitable connector at one end to connect to the DataLOG, and a hand held switch at the other.
  • IS3LED – Same as the IS3, but with a LED in the hand held switch, which illuminates when the switch is pressed for visualization on video recordings.

Remote Start / Stop Switch

  • IS4LED - The IS4LED remote start/stop switch is a 1.8 metre cable with a suitable connector at one end to connect to the DataLOG, and a hand held switch at the other. Pressing the switch will activate the start or stop recording function. An LED in the hand held switch, which illuminates when the switch is pressed for visualization on video recordings.

Record Indicator

  • IS5-LED - Used for video synchronization, the IS5LED is an indicator LED switch which illuminates when the MWX8 DataLOG starts or stops recording data.

Multi Unit Cable

  • SL100 - It is strongly recommended that the SL100 Synchronization Cable is connected when using more than one DataLOG simultaneously to achieve 16 or 24 channels of data collection. The SL100 cable connects to any one of the digital channels on each unit.

Synchronization Cables

  • SYNC1 - For remote start / stop by a TTL signal {i.e. the ability to switch a signal line from logic 1 (+5V) to logic 0 (+0)} sent from other hardware systems to synchronize data collection from multiple sources (ie. DataLOG is a slave). The SYNC1 is a 3 metre cable with a connector at one end to connect to the digital input socket of the DataLOG and 2 flying wires at the other end. Alternatively, this cable may be specified with any connector of choice.
  • SYNC1BNC - A synchronization cable with a BNC connector fitted for interfacing to certain 3rd party systems such as Qualisys or Vicon. Connector chassis is wired as common or ground. NOTE: Please contact Biometrics Ltd or the 3rd party equipment manufacturer for specific instructions before this cable is used.
  • SYNC5 - For remote start / stop by a TTL signal sent to 3rd party hardware systems to synchronize data collection from both sources (ie. DataLOG is the master). The SYNC5 is a 3 metre cable with a connector at one end to connect to the digital input socket of the DataLOG and 2 flying wires at the other end. Alternatively, this cable may be specified with any connector of choice.

Contact Switch Assembly

  • FS4 - An assembly of 4 Force Sensing Resistor Sensors (FSRs) each on 1.2 meters of cable which are readily connected to the DataLOG via one connector for use as switches to indicate contact e.g. heel and toe strike or palmer contact. The sensors are thin and robust and are usually placed inside the subject's shoe or glove for convenience.
