A Quick Guide To Networking - MOTU 1248 User Manual

Large-scale venues
With long cable runs and industry standard
networking infrastructure, MOTU AVB systems
are well-suited for large-scale commercial
installations such as arenas, stadiums, theme
parks, clubs, casinos, houses of worship, broadcast
facilities, schools, universities, and so on. Audio
streams can travel long distances with sub-
millisecond latency through as many as seven
switches. Audio can be distributed from a
centralized location to anywhere in the venue.

A QUICK GUIDE TO NETWORKING

MOTU AVB networking has been designed to be
powerful, yet straightforward to set up and use.
Here are a few things that are useful to know.
Networking basics
Before proceeding below, review the networking
■
connection diagrams on pages 43-45.
To make network connections, use shielded
■
CAT-5e or CAT-6 cables (a higher grade cable).
Network cable lengths can be long: 100 meters
■
with standard copper wire cables; much longer
with fiber-optic network cables.
Working with AVB switches
Networks of three or more interfaces require an
■
AVB-compatible switch. You can use any standard
AVB switch on the market. MOTU offers the five-
port MOTU AVB Switch™ (sold separately).
☛
A non-AVB compatible switch will not work.
Connect MOTU AVB interfaces to any AVB
■
Switch using their NETWORK ports.
On the MOTU AVB Switch, connect MOTU
■
interfaces to the five AVB NETWORK ports (not
the Ethernet port). Connect the Ethernet port to a
WiFi router, your Local Area Network (LAN) or
your computer (for running web app only).

MOTU AVB interfaces or
other AVB switches
Expand the network by adding more switches.
■
Make a single connection from one switch to the
other. On MOTU AVB Switches, use their AVB
NETWORK ports, NOT the Ethernet port.
You can daisy-chain switches in serial fashion,
■
but don't create loops. For example, in the network
below, do not make any additional connections
between any two switches.

C
AVB audio can't pass through more than seven
■
switches. However, you can daisy-chain more than
seven switches and route audio freely among them.
You just won't be able to create point-to-point
connects that span more than seven switches.
Working with computers on a network
Computers are not required for network
■
operation, as you can control the network from
iPads, tablets and smart phones.
