Wordclock for Ring Topologies
For ring topologies, the device for which the user sets Ring Active becomes the Preferred
Primary Master and assumes the role of wordclock master. In the event of a cable failure,
the network reverts to a daisy chain network. In this case, the wordclock master device
automatically switches from the Preferred Primary Master to Primary Master, the device at
the start of the daisy chain. From the moment of ring failure until wordclock switchover is
complete, to avoid audio interruptions, all devices must be configured to receive wordclock not
from internal oscillators or external sources but from the EtherSound network. Also, all
devices should have their Emergency Clock set to ON.
AuviTran Firmware for Ring Topologies
Before connecting devices in a Ring Topology, make sure that AuviTran firmware version
“C0F” or greater is running on all Yamaha EtherSound devices. The AuviTran firmware
version can be checked in the AVS-Monitor Properties tab.
Note: The AuviTran firmware version number uses the hexadecimal (base 16) numbering
system. The symbols 0 through 9 to represent values zero to nine, and A through F to
represent values ten to fifteen. C0F < C10 < C11 < C12 …etc.
