The DataHub black stubby GPS is connected
Please screw in the black stubby GPS antenna, which ships with the DataHub. To receive a GPS position, the DataHub is best flat-mounted with the GPS antenna tilted towards the sky. The GPS antenna may take some time to find an initial fix. You may need to place the DataHub outside, near a window, or high in the cockpit to get a GPS fix.
Even if you plan to use the NMEA2000 / N2K network to provide a GPS source into the DataHub, it's a good idea to connect this antenna because it will provide a backup GPS source in case your boat is struck by lightning and your NMEA network is destroyed, or in case your boat instruments go offline for any reason.
The GPS antenna may be faulty and unable to achieve a GPS fix. If you have attached it and cannot get a fix after one hour, and you received the DataHub Accessory Pack with your delivery, please connect the GPS patch antenna it shipped with instead of the Black Stubby antenna.
If you cannot achieve a GPS status Active with either of these antennas, as below, and you're sure the DataHub and antenna are well positioned, please contact us for support.
Complete GPS Tracking Setup
If you have not done so already, please follow the step-by-step guide here to set up GPS tracking for your boat:
Update DataHub Firmware
For customers using the GO exec to update positions, the DataHub must run the latest Firmware if they are on the GO exec PredictWind Unlimited Data Plan. Please update the Firmware, then try again.
NMEA network is enabled as the NMEA source
Log into the DataHub on 10.10.10.1
Login and password: admin
Click the NMEA menu.
If you have connected the NMEA2000 / N2K network to your DataHub, select Source NMEA2000 on CANO. If you need to change this, please click SAVE & APPLY.
Click on the top menu GPS.
Check the GPS Status is Active and that a full reading of GPS data is being received.
Check the DataHub has an Internet connection
Click on the Settings menu.
Check the WAN Interfaces; at least one box must be coloured green with Status: Online.
If you are using the GO! or GO! exec, then the box being red is expected; this is OK. It's best to use a USB tether, Cellular, Starlink or Wi-Fi connection to resolve GPS tracking issues. If you cannot, please ensure the GO!/exec is connected and activated when you click Position in the next step.
Check Tracking is enabled, and positions are not spooling
Click the Tracking menu.
Check that Enable Tracking is ticked.
Check the Network Spool count is 0. If positions are spooled, they are pending to be sent.
If you see spooled positions, click the Tools menu.
Click POSITION to send your position immediately.
Check your tracking page after 1-2 minutes to see if it has updated, and check that the spool count is now 0.
If the spool count is still increasing, return to the Tools menu, click RESTART, wait one minute, then click POSITION, and recheck it.
If required, please press PURGE to delete pending reports and start again.
Check the Tracking SysLog
Once you have sent a position report manually, after 1-2 minutes, please check the Sys Log. If it shows lines like the above, your tracking reports are being sent successfully. If you see failures reported, please copy and paste this into an email with your DataHub Serial number from the Tracking Page and Contact Us for more help.
If you see errors like this in your SysLog, or similar issues where files cannot be read, please reformat the SD card on the DataHub, as your file system may be corrupt.
The solution is to reformat your SD card and set up PredictMail again, if you have it. To do this, your DataHub must have Firmware version 3.92 or later.
See below if you don't have PredictMail, or click here to jump down the page if you do.
Reformat your SD Card without PredictMail
Update your Firmware if it is not 3.92 or later.
Click on Settings under the Services menu.
Click on the Maintenance top menu.
Click the FORMAT button and click OK.
Please wait around 5 minutes for the DataHub to reformat your SD card. Your browser might show it doing this continuously, not letting you know when it is complete. It will be finished after five minutes. Please refresh the page.
Send a fresh Position report from the Tracking->Tools page.
Wait 1-2 minutes and check your tracking page.
Click here if that doesn't resolve the issue to send your Serial number to Support.
Reformat your SD Card with PredictMail
Important Note: Please use your email app to download any email from the DataHub first before following the steps below. Please ignore these first steps with PredictMail if you have not bought this.
Log into the DataHub on 10.10.10.1 with username and password: admin
Update your Firmware if it is not 3.92 or later.
After the Firmware Update, login to the DataHub again and click on PredictMail.
Remove the tick from Enable Email, then click Save and Apply.
Click on Settings under the Services menu.
Click on the Maintenance top menu.
Click the FORMAT button and click OK.
Please wait around 5 minutes for the DataHub to reformat your SD card. Your browser might show it doing this continuously, not letting you know when it is complete. It will be finished after five minutes. Please refresh the page.
Log back into the DataHub and re-enable PredictMail with your email address, password and full name per initial setup. Click FORCE SETTINGS if you are offshore, so it will save the settings without validating they are correct.
Click Save and Apply.
Your Inbox and Outbox should now load as expected, and downloading a new email will work if the DataHub is connected to the Internet.
Send a fresh Position report from the Tracking->Tools page.
Wait 1-2 minutes and check your tracking page.
Send the Serial number to Support
If position reports are being sent from your DataHub successfully, and you are not seeing these reflected in the tracking page from your boat within a few minutes, please copy and paste the DataHub serial number and send it to us so we can check the set-up from our side. Please click here to contact Support.
Also, if you have a cellular or Wi-Fi/Starlink Internet connection, enable remote support with Startup on Boot and Persistent Connection so we can log in remotely and review your DataHub.
