Update and ProAIS2 can't find unit

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum kalakai,

When interfacing the AIS650 to a computer and using the PROAIS2 software, the operator must first disconnect the AIS650 from all other devices and sources of power ... i.e. the AIS650 will be only be connected to a USB cable, which in turn will be connected to the PC. Please verify that you have done so and should the problem persist, then please respond accordingly. You may also want to consider trying another USB cable before responding

Regarding update the AIS650's software, it is recommended that the AIS650's software be updated via a SD memory card rather than via an interface to a PC. If updating the AIS650's software via a SD memory card and you experience an issue, then please respond accordingly.
