This raises a question. We're often in the position of having to fill in a dummy gateway address to make some configuration app happy. Is there a standard or proper value to use? One least likely to cause a problem? Scott?
If you must choose, all 0's is the correct choice. It means 'no gateway.' This is why that is the default. Dante doesn't work with gateways (unless you have DDM).
According to the CL/QL Series System Design Guide, it IS the 'Device Control' tab.
. . . 'Device control' tab sets the IP address for the Primary Dante connection.
Almost. Dante Primary and Secondary can only be set in Controller, because that is the Audinate Brooklyn II card.
'Device Control' is the Yamaha's internal interface, for the purpose of injecting control onto the Dante subnet. The document is clear that there are three interfaces involved, and how each one must be set. It basically suggests device control should be on the Dante Primary subnet.
In my experience some Dante devices seem to require being connected directly to them and/or powered cycling to take IP address changes. Whether you fill or don't fill DNS and gateway does not make a difference.
