[DG] Raymarine 400G and Lighthouse 3

[svalvasori]

Is the 400 or 400G autopilot computer with the ST600R control unit designed to work with Lighthouse 3? I have the converter installed and passing data but am not able to enable auto pilot slider in the MFD display settings. The MFD's are es127 and Axiom 7.

Also, I see heading coming from the autopilot and displaying on the MFD's, but there is a 10 degree offset (autopilot control shows 120 deg and the MFD shows 110 deg). What would be the cause of this?

Thank you,

Steve.

HI svalvasori

Thank you for your enquiry

The older autopilots cannot be controlled from the AXIOM or LH3 units, only newer autopilots such as Evolution systems.

The difference in heading is likely to be Variation? Can you check Variation is set to AUTO in the LH3 units?

Also check there is only one source of Heading data in the system and no data loops are possible within the installation
