I am updating my FLARM config and am seeking advice on the protocol version. I can't see any mention in the S100 manual but have seen Paul's advice to use V9.

V7 is default in FLARM configurator and I'm not sure what the LXNAV tool uses as default.

Can anyone confirm that V9 is good to go with the S100?
Bonus points for explaining what changes between versions and if there is any real world benefit of one vs the other with an S100 and standard PowerMouse.

Thanks

Hi Peter,

I always select the latest FLARM protocol (currently version 9) when setting-up FLARM units and in my own sailplane. It works great with my LXNAV products.

Best Regards,

Protocol version for data port 1 on the PowerFLARM Fusion (often just called FLARM Fusion) refers to the version of the FLARM proprietary data port protocol (also known as the Interface Control Document or ICD protocol) used for outputting data on that specific serial data port.

FLARM devices like Fusion have multiple data ports (typically Data Port 1 and Data Port 2) that connect to external displays, EFIS, or other instruments. The protocol version determines the format and content of the data sentences sent over the port, such as traffic information ($PFLAA), status ($PFLAU), and others.

Newer versions include additional fields and features (e.g., better support for ADS-B/Mode-S targets starting from version 6, more detailed signal strength from version 9, and other enhancements).
It is a configurable setting in FLARM Hub (the web-based configuration tool accessible via Wi-Fi).
Recommendation from FLARM documentation: Set the highest protocol version supported by the connected display or device, along with the highest compatible baud rate, to maximize information transfer without overwhelming older devices.

This ensures compatibility and optimal data flow. For example, older displays might only support up to version 6 or 7, while modern ones handle the latest (currently up to version 9 or higher in recent firmwares).

If you're seeing this in the configuration menu, check your connected device's manual for its supported ICD version to avoid data loss or incompatibility.
