What is Network ???– a stuff that is consisted by nodes and

routes, there is flow in it.

f Wiki difrom Wikipedia…Human networks

Business network, Entrepreneurial network, Social networkEconomic network, Old boy network,

MediaRadio network, Television network,

TechnologyElectrical networkComputer network, Telecommunications network, Energy transmission and distribution networks

Focus on “computer network” !

Definition of Network in General

C i d b h h d l• Consisted by more than three nodes, alsopossible to communicate each other

Page 5: Network101.ppt [modalità compatibilità ] Networking.pdfProtocootoco eac ayel in each layer OS fOSI reference model 7 Application HTTP, SMTP, SNMP, FTP, Telnet, AppleTalk, X.500 6

“Non-Network”

“Point to Point”• “Point to Point”• Communication between two nodes

e.g. RS232, AES/EBU, MADI etc.

Criterion for separation?p

AES/EBU is Point to Point• AES/EBU is Point to Pointbut… utilizing with matrix router, it works as Network g

• Computer Network is…connection PC and switch is Point to Point

�we call its mass ”Network”�

There is no clear criterion...

But, the separation helps to understandfeatures of a format

Pros / Cons

• “Point to Point” style format has…E t lik l i i– Easy to use, like analog wiring

– Less flexibility comparing “Network”

• “Network” style format hasNetwork style format has…– More flexibility comparing “Point to Point”

S ti d IT kill ( diffi lt)– Sometimes, needs IT skill (more difficult)

Benefit of Audio Network• Cable

– Less thickness, Less weight, Less number,• Routing by software• Routing by software

– to reduce “on site job”j– needless to patch physical cable

• Possible to carry control signal

Comparing with analog systemComparing with analog system

• New factors– Latency– Latency

• System design considering latency

R d d– Redundancy• Cable damage might effect on whole system• Cable redundant and network device redundant

– Different skill for audio system designDifferent skill for audio system design• Needs network skill (case by case)

TipsTipsTipsTips• IN port is “MDI”, OUT port is “MDIX” (Old products). Take suitable

cat5 cable straight or crossedcat5 cable, straight or crossed.

• Device name is memorized in PC, linking with MAC address.

Setting is memorized in ES device but don’t forget to save setting• Setting is memorized in ES device, but don t forget to save setting into memory on ES device. Take “write to non-volatile memory”

• “IN” means audio flow from Yamaha device to EtherSound

• Clear “LOOP BACK ON” before starting to design configuration. Use “force to Mono direction”.

• Clear “TUNNELING ON” before starting to design configuration.

• Use special serial cable for HA remote between mixer remote port and AVY16 ES serial portand AVY16-ES serial port.

• Before loading cfg file in ES monitor, make it offline mode.

MUTE “Cl ti ” Mi d it!!• MUTE means “Clear routing”. Mind it!!
