Diagram of a typical hardware configuration for the Datahub

Physical & Power installation

  • The DataHub should be installed in a dry location in the boat, that is, within a 2m cable run of your NMEA2000 instrumentation system. If no instrumentation system is available, please install it in a location where the GPS antenna will receive reception.

  • The DataHub should be powered with a DC power supply directly from the boat's house battery bank.

  • The unit requires 9-60 VDC and is reverse polarity protected.

  • The centre pin of the power connector is positive. To wire the DataHub directly to the boat’s house battery, start by cutting the power lead off of the supplied AC/DC adapter. Connect a 3 amp fuse to the positive power lead (The black wire is positive, and the wire with a white stripe is negative) and wire to the vessel’s switch panel.

  • Before powering the DataHub use a voltmeter to ascertain that the centre pin in the connector has a positive voltage. Reversing the polarity on the connector will not damage the DataHub, but it will prevent it from powering on.

  • You will notice a blue status LED on the top of the unit illuminates when the unit is correctly powered on.

NMEA 2000 (N2K) installation - Highly Recommended

  • The DataHub has an optional N2K cable and T-connector to connect the DataHub to the boat's instruments to receive all N2K data, including GPS position, True Wind Speed/Direction, Depth and AIS data if available. Getting GPS data from a marine GPS installed on decks will guarantee the accuracy and reliability of the GPS data. The True Wind Speed/Direction data is a great safety feature for your GPS tracking page so friends and family can see you in real-time weather conditions. All of this data is also essential for the PredictWind Anchor Alert App.

  • Connect the N2K cable to the back of the unit, and insert the T-connector into the N2K instrumentation system. You have now completed the physical installation.

  • If you do not have an N2K instrumentation system and optional N2K cable, you will need to use the supplied GPS antenna.

DataHub N2K Setup

It is important to change the settings in the DataHub to take advantage of this N2K data.

  • Connect your laptop (Recommended) or mobile device to the DataHub Wi-Fi network. It will look like PW-Hub-XXXX in the list of available Wi-Fi networks on your device.

  • Open a Chrome or Safari browser and type in the URL bar.

  • Log in with username admin and password admin.

  • To get the GPS, Wind Speed/Direction, Depth & AIS data, go to the left menu, select NMEA and click on the drop-down box to select NMEA2000 on CAN0.

  • Then select Save & Apply.

Automatic Polar updating

  • Select Polars from the left menu, then click the check box Automatic Mode, then Save & Apply. This feature will automatically update your boat polars as you are sailing. You will need the professional package of PredictWind to take advantage of this feature.
