[DG] [DG11] AIS 650 Connection failure

[Derek - Raymarine - Moderator]

Hi Uckel

Thank you for your enquiry below.

Please check that you have the latest version of PROAIS2 - this can be downloaded from the Raymarine website.

Please test with a different USB cable, we have seen numerous issues with this connection porblem attributed to a defective USB cable, often the cheaper cables sourced over the internet create problems.

If you are just powering it via USB, then either the USB port is not delivering enough power to the AIS, try a different USB port or power the AIS650 via STng, in this case make sure the laptop is running on battery only - not connected to the vessel's 240V since this may create a ground loop and trigger rthe problem too.

Regards

Derek
