RING ARCHITECTURE
Thanks to the native ES100 kernel of AVY16-ES100, you will be able to integrate your
device into EtherSound Ring architecture. Building a ring will improve redundancy of your
network.
A ring is a closed EtherSound loop, with one device configured as “Preferred Primary
Master” (PPM). The PPM acts as a usual primary master, i.e. it is the one that generates
the clock. Thanks to 3
rd
port, you are still able to control and monitor your network (as
the “IN port” of the PPM is now unavailable).
In this configuration, only 64 channels are available, as you must always insert audio
downstream, and extract upstream. Loopback is also automatically activated on each
device when ring mode is turned on. When a link is broken, the device which has its “In
port” open becomes automatically primary master and audio is not interrupted more than
few milliseconds.
This system is safer than a classic daisy-chain, as a dead link will interrupt audio and
data transmission only few ms before recovery. However, you can handle only 64
EtherSound channels, and not 128.
Notices:
-
Preferred Primary Master (PPM) must be unique in a ring.
-
PPM must be set before closing the ring.
-
Audio must be inserted downstream and extracted upstream (only 64 channels
available).
-
PPM does not exist on non-ES100 devices.
-
Devices with kernel < 2.09 must be VOID as data transmission from non PM may cut
the audio.
-
Kernel 2.09 can introduce noise at reconnection.
