Iridium 9555 and 9575/Extreme and Win-10 Drivers

The original Iridium USB drivers for the 9555/9575 handsets were not compatible with Windows-10, resulting in a “blue screen” Windows crash whenever the USB port was opened. It took a long time for updated drivers to become available, in the meantime we created a work-around (details below) which is no longer needed.

A CD that came with a recently-purchased phone will have the correct drivers, or you can download them from Iridium at this website: https://www.iridium.com/services/data-tools/

There are two downloads on that site, the “Iridium 9555 – USB and Modem Drivers” download is a zip file containing the driver files themselves which can be used with Device Manager’s “update drivers” function. (Save the download file, open WIndows Device Manager from the Windows search box, find the Iridium handset under “Ports”, right-click and select “Update Drivers” then browse to wherever you saved the driver files).

There is also a “Iridium Handsets – USB Driver Installer” download on that Iridium page, which is a driver-installer program which can be run to install the drivers. Download that file, then run (open) that file with the handset disconnected from the computer to install (or re-install) drivers.

Alternately you can download the driver-installer from our website here: http://siriuscyber.net/sailmail/Iridium Handset USB Driver Installer 6.3.9600.9520.exe  Again, be sure the handset is disconnected from the computer.

If you want to read the Iridium release notes click here: http://siriuscyber.net/sailmail/IRDM-1023-SRN-007 v1.3 – Iridium Handset USB Driver Installer – 6.3.9600.9520.pdf

An important note: We have received reports that Windows-10 update will occasionally overwrite these driver files with versions that won’t crash, but also won’t connect. So be sure to keep a copy of the Iridium drivers or diver-installer, and re-install the Iridium drivers if you encounter this after a Windows update.

If you have already done our previous work-around, then no need to un-do that.  If you installed ver 3.5.041 of our Airmail software and used the driver-checker then again this works fine, but you can re-open  Airmail’s “Check Iridium Driver” (under Tools menu) and click “Reset Driver-Test Mode”.  Also, if you disabled the UEFI “Secure Boot Mode” then you can re-enable that if you want:  From the Windows button click Power, Shift-Restart, Troubleshoot, Advanced Options, UEFI Firmware settings, Restart, “Secure Boot Control”.  Whew!

Once the drivers are installed, go back to the Iridium set-up page to finish the setup.

How to request PredictWind data via email/SailMail

How to download with a Satellite/SSB Connection using an email request

NOTE: This help topic is not relevant for Iridium GO! users, which can be used to download direct.

• Open the PredictWind Offshore App

• Move your start point (green) and your destination point (red) to your desired locations. You can zoom in and out to get a better view of your route. Please ensure your start and destination points are in the water and not on land. Each time you change your route the App automatically selects the relevant high resolution & offshore GRIB files, GMDSS text forecasts & Satellite imagery.

• You can add intermediate waypoints (between start and destination) by clicking on the “+” button next to the start waypoint control – top right of the screen. For the purposes of weather routing, we recommend that you minimise the number of waypoints so the weather routing is free to find the optimum route.

• Click ‘Download’ button from the left menu

• Make your selection of items to download. The total file size to receive via email is shown above the download button.

• Click ‘Next’.

• Choose ‘Email’ tab.

• Make your final selection of items to download. The total file size to receive via email is displayed below the table.

• Click ‘Save Request’ – save the file to to a “PredictWind” folder on the desktop or under “Documents”

• Open a new email. Send the saved file to offshore@predictwind.com by attaching the file to the email. You can leave the subject line blank. Please Note: The email will be sent back to the email address that you send the request from.  You do NOT need to change the email address for your PredictWind login.  

• After a few minutes you will receive multiple emails with GRIB files and PWU files.  Save these files to a “PredictWind” folder on the desktop or under “Documents”.

• Go back to the PredictWind Offshore App.

• Click File > Open and open the folder where you saved the files. (Hint: Sort by date so that the new files are at the top). Use the ‘ctrl’ button to select multiple GRIB files, and the PWU file.

• The PredictWind Offshore App will then load the files into the app. You can then view the files that you have downloaded by clicking on the different Menus and Views

NOTE: For SSB radio services there are maximum file sizes that these services allow. Please make sure your requests are below these limits.
