    1. General X2 Environmental Data Logger Overview The X2 is an all-in-one environmental data logger that can be controlled from any internet browser using a smartphone, tablet, or PC. It automatically recognizes sensors and sends data to the WQData LIVE web data center via Wi-Fi, cellular, radio, or satellite telemetry.

  • Page 6: Internal Features

    Power Port: (1) 6-Pin for Power and Communication (Primary/Secondary/Backup Input, RS-485 Host, GND) Direct Communication CONNECT software enables users to interface directly with any NexSens X2-Series data logger using a UW6-USB-485P cable. It supports a growing number of diagnostic and configuration tools to facilitate system setup and troubleshooting.

  • Page 7: Telemetry Options

    Telemetry Options The X2 supports Wi-Fi, radio, cellular, and satellite telemetry. A radio to cellular option is also available. Wi-Fi Communications: 802.11b/g/n (Direct to X2 or Connect X2 to an existing network) Antenna: Internal to device Range: 250 ft. maximum Actual distances may vary by location.

  • Page 11: Typical Applications

    This setup is ideal for long-term, unattended monitoring applications as it provides a constantly recharged battery source. However, solar systems are more susceptible to damage and failure than a simple battery. The X2 provides the benefits of a solar-charged system while simultaneously allowing for a backup reserve battery to be connected. The reserve battery can provide power to the system if the solar panel stops charging the main battery without an interruption in data collection.

    CON). This ensures that all signal wires are connected to the appropriate pins, and the connectors are sealed with epoxy to provide fully waterproof connections. While this is critical for use on buoys (X2-CB, X2-SDL data loggers) and in other wet environments, users may in some cases choose to install UW Field Wireable Plugs (part number UW-FWP).

    Contrarily, X2 data loggers use sensor detection to simplify the programming requirements for environmental measurement systems. At startup, the X2 automatically scans each of its sensor ports for sensors connected to the logger. This process works by running a series of scripts designed to check for the presence of common sensor types.

    (12) X2 meta parameters/diagnostic readings. X2 Meta Parameter Descriptions 1. Processor Power – The regulated supply power being fed to the X2’s CPU and other internal components. It is nominally 3.3V but typically ranges between 3.2-3.5V. 2. RTC Power – A real-time clock (RTC) lithium coin battery inside each X2 allows the logger to maintain accurate time while powered down or reset.
  • Page 76 All other systems will return ~0V (as shown), indicating that no secondary power input is present. 5. Sensor Power – The X2 regulates power to its sensor ports. Depending on the state of the system’s primary or secondary power, the X2 will boost or reduce sensor power accordingly to maintain a nominal 12V output.
  • Page 77 9. Internal Temperature – Registers the ambient temperature inside the housing of the X2 logger. 10. Internal Humidity – Reflects the amount of moisture in the air inside the X2 housing. Acceptable values will range from a slight negative percentage (effectively zero) up to ~50%.
  • Page 78 Expected values are given in the following: 1. Cellular systems a. -51 to -79 dBm for strong signal strength (~4-5 bars equivalent) b. -80 to -89 dBm for moderate signal strength (2-3 bars equivalent) c. -90 to -99 dBm for weak signal strength (1-2 bar equivalent) d.
  • Page 79 12. Cell Status – The cell status field displays error codes from a failed or compromised X2 data transmission attempt. Similarly to cell signal strength, the cell status parameter applies to all telemetry types including cellular, radio, Iridium satellite, and Wi-Fi.

  • Page 80: Field Installation

    The X2’s mounting kit accessory provides an easy way to attach the logger to a pole, pipe or wall. Mount an X2 to a 1-1/2 to 2″ (38 to 50 mm) pole by following the instructions in this guide. Alternatively, user-supplied screws may be used to mount an X2 to a wall.

  • Page 82: X2 Data Logger Grounding

    Regardless of the environment, measurement systems should always include proper grounding of a data logger and other electronics. Proper grounding helps reduce the risk of expensive damage to the system. For this reason, the X2 data logger comes standard with a grounding kit recommended for installation.

  • Page 83: Troubleshooting And Maintenance

    7. Troubleshooting and Maintenance Running a Sensor Re-Detection After running a sensor auto-detection during initial setup, WQData LIVE receives and parses the specific XML data format that outlines the logger’s sensor configuration (i.e., sensor id, parameter ids, parameter units, etc.). Once the sensor configuration is received, it is saved on the backend of WQData LIVE and used to parse data for future transmissions from the logger.

  • Page 84: Confirming The New Sensor Configuration

    After a successful re-detection, the new sensor configuration must be sent to WQData LIVE. Depending on the extent of the changes, the user may need to contact a support specialist at NexSens Technology to re-create the device on the web. NexSens Technical Support Line: (+1) 937-426-2703 Re-creating the device will make the original device obsolete on the web.
