There are two options for downloading weather data on a Satellite Connection.

NOTE this does not relate to Starlink, Iridium GO exec or the Iridium GO.

For Starlink use WEB as the download method.

Both options require the Standard or Professional Forecast Subscription.

1) Satellite

This option is recommended if you have a high speed internet connection, that already comes with a Wi-Fi or ethernet connection for your boat, and also a firewall to prevented unwanted traffic. ie your system already has the built in capabilities of the Optimizer. For example an Iridium Certus unit.

Set-up Instructions for Offshore App and Satellite download option:

Please make sure these ports and IP addresses are white listed and open with your device and satellite provider. Please contact your satellite provider if you are unsure how to do this.

IP ADDRESSES:

23.21.179.247

107.22.198.134

107.21.94.132

23.21.175.100

PORTS:

  • Ensure the Wi-Fi on your laptop is connected to your Satellite device

  • Click on the Download Button, then "Next", then select the "Satellite" as the download method.

2) Optimizer

What does an Optimizer do?

  1. This device can connect to any Satellite System to create a Wi-Fi hotspot for any easy connection of laptops, phones & tablets.

  2. The Optimizer contains all the software device drivers, so all software interface issues are eliminated.

  3. The Optimizer contains a firewall to prevent unwanted windows downloads (for example) over your satellite connection.

  4. Get weather downloads direct into the PredictWind Offshore App, so you do not need to go through the numerous steps for an email request.

Set-up Instructions for the Offshore App and Optimizer

  • Open the Offshore App, and go to Preferences > Optimizer and select your connection type. Then close the preferences

  • Ensure the Wi-Fi on your laptop is connected to the Optimizer.

  • To do a download with the Optimizer, click on the Download Button, then select the "Optimizer" as the download method.
