Control Master Functions
This section describes the individual functions of the Control Master device
in a Pro64 network.
Enumeration
When the Control Master is powered on, its first job is to identify and count
all connected A‑Net modules in the network in a process called
enumeration
.
The time for this process will vary based upon the number of Pro64 modules
in a system. This process cannot begin until the host Yamaha device has
finished its own power‑up cycle when a 6416Y2 A‑Net Interface Card is the
Control Master.
Enumeration is an automated process performed by the command and
control portion of the A‑Net software. There are no user‑controllable
functions or settings.
During the enumeration process, all connected A‑Net modules will flash their
blue A‑Net LEDs, indicating that a request to be added to the Pro64 network
is being made. Once granted entry by the Control Master, the individual
module’s blue A‑Net LED will light solid to indicate that it is now receiving
valid A‑Net packets and is part of the Pro64 network.

The blue LED is used to indicate network status.
If valid A‑Net packets are not received, the module will reset and wait until a
valid A‑Net stream is detected.
During enumeration, any conflicts will also be resolved. For example, consider
a new Auto Mode installation using eight input modules set to the same
A‑Net Slot range with all channels activated during a bench configuration.
When all these input modules are connected and then powered up, only
one of them will be allowed to have all 16 channels activated. The remaining
seven modules will have their audio channels deactivated. Conflicts with
channel activation on 6416Y2 cards must be resolved manually since Slot
activation is controlled via DIP switches.
