PowerMouse & S100 protocol
Peter Piper
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.

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.

I just didn't see anything in the S100 manual about which protocol versions it supports.

Both the LXNAV V9 and S100 use the standard FLARM data protocol over serial (RS232) connections for integration with external FLARM devices.
Key Details- Protocol: They receive and process standard FLARM NMEA sentences (primarily $PFLAU for status and $PFLAA for traffic targets). This is the universal FLARM data output format used across manufacturers.
- Connection:
- The S100 has a dedicated GPS/FLARM port (RJ12 connector, RS232 level) for direct connection to external FLARM/PowerFLARM units. It displays FLARM traffic (radar view, warnings) when connected.
- The V9 (as a vario unit, often paired with larger LXNAV systems like LX80xx/90xx) receives FLARM data via the system's bus (CAN/RS485) or serial input from an external FLARM module connected to the main unit.
- Baud Rate: Typically 19200 bps (common default for FLARM), though configurable in some setups.
- Compatibility: Works with classic FLARM, PowerFLARM, LXNAV's own FLARM modules (e.g., FlarmMouse, PowerMouse), and third-party units, as long as they output standard FLARM sentences.
No special or proprietary "FLARM protocol" variant is required—these units adhere to the open FLARM data specification for interoperability.
