Compatibility between Raymarine Axiom and eS/gS Series – Important Limitations and Recommendations

Learn which Axiom models can be integrated with older eS and gS systems, which require downgrading to LightHouse 3.11.42, and which only work with LightHouse 4.

Raymarine continues to develop the LightHouse 4 operating system with new features and improved performance. This means that the ability to downgrade the software to LightHouse 3.11.42 has ceased for certain Axiom models. Downgrading has previously been necessary to ensure compatibility with older eS/gS Series systems, but more modern hardware such as Axiom+ and Axiom 2 series can no longer be downgraded.

Why is this important?

If you plan to integrate an Axiom display with an existing eS or gS system, you must check compatibility before installation. Incorrect combination can lead to units not communicating correctly, affecting functions such as chart sharing, radar, and network integration.

Axiom Pro and older systems

Axiom Pro models manufactured after August 2022 can no longer be downgraded to a LightHouse version compatible with the eS/gS series. This is an important detail for those who upgrade incrementally or retain older units in the system.

Compatibility table for Axiom models

The table below shows which Axiom models are compatible with eS/gS Series and what limitations apply:

Recommendations for upgrading

• Check the model's manufacturing date before planning integration with older systems.
• If compatibility requires downgrading, ensure you have the correct LightHouse version (3.11.42).
• For new Axiom 2 models, it is recommended to upgrade the entire system to LightHouse 4 for best functionality.
