CHAPTER 1
Understanding the i.LON 10
As discussed earlier in this chapter, the i.LON 10 Ethernet
Adapter converts twisted-pair network data to Ethernet
network data, allowing you to connect RMS to one or more
LNS servers via the TCP/IP protocol.
Each i.LON 10 must have its own static IP address, which
will provide its RMS identity as a network segment in the
network database. It will also have its own database in the
RMS host computer and each network database segment
will contain all of the Neuron ID (the unique loudspeaker
identification number) information on the network for the
loudspeakers contained on that particular segment of the
network.
NOTE:
i.LON 10 installation procedures
are covered in more detail in Chapter 2,
“Installing Transition Hardware.”
Hubs and Switches
A hub is a device that joins multiple computers or other
network devices together to form a single network segment.
Switches look nearly identical to hubs, but a switch is
more intelligent. Switches are capable of inspecting the
data packets as they are received, determining the source
and destination device of that packet and forwarding
that packet appropriately. Switches conserve network
bandwidth and offer better performance than hubs.
A Hub or a Switch is needed for an RMS Ethernet network
that contains more than one i.LON 10 or if you are sharing
an existing Ethernet network connection.
NOTE:
A network repeater or an Ethernet-
based system with multiple i.LON 10s is
required if you want to connect more than 62
loudspeakers to an RMS host computer. This
will increase the data traffic capacity through the
network as well as signal strength over longer cable
runs.
TIP: While it is possible to wire an RMS
system in a near-infinite number of ways, a
typical network using Free Topology (flexible wiring
configuration) can only address 62 loudspeaker
nodes over a maximum cable length of 500 meters
(1,640 feet) using 20 AWG cable and a single
bus terminator (a terminator is a simple resistive
capacitive device designed to prevent network
reflections.).
NOTE: Each i.LON 10 equals one network
segment. You can have many network
segments within a network depending on your
installation needs.
