NETWORKING
NETWORKING OF SPEAKERS
All the speakers are equipped with a dual Ethernet port for connection
to INFINITO MANAGEMENT SOFTWARE and a high-brightness front
BLUE LED that allows you to physically identify the speaker when
connected to the network and remotely controlled.
With the WINK function present on the INFINITO software, the LED
flashes allowing the association between the virtual device in the PC
workspace and the physical device.
There are 3 ways to connect to the network:
1.
Star connection: it is possible to connect each speaker individually
to the network by connecting the NET IN port directly to the dedicated
switch. This type of connection is the simplest from the point of view of
the complexity of the network itself, as it involves the least number of
HOPS (switch jumps that a packet must make from the PC to the target
device). This type requires a large number of network ports on switches
and also very long wiring to reach the farthest devices (for example, the
speakers at the end of a line array). From a safety point of view, a faulty
network cable results in a loss of control on only one device
2.
Daisy Chain connection: it is possible to connect a whole series of
speakers close together (e.g. Line array) to a single switch network port,
using both available NET IN and NET OUT connections. Simply connect
the switch port to the first speaker through the NET IN port, then wire
the NET OUT with the NET IN of the second speaker, and so on to the last
in the series. This type of connection simplifies the physical operation of
wiring, resulting in being able to use shorter cables (similar to the set-up
for the analog signal link), but complicates the structure of the network
and increases the number of hops (and therefore the arrival time) of
network packets especially intended for devices at the bottom of the
chain. Any interruption of a network cable results in the loss of control
on all devices located downstream of the breakage
3.
Mixed connection: it is possible to use a mixed structure, dividing
each cluster into subgroups of devices. The first device in each group
is connected via NET IN to the switch, then using the daisy chain
structure the other elements are connected. In this case, an intermediate
complexity network is obtained both from the physical point of view
of the wiring and from that of the operation of the network itself. The
interruption of a network cable causes the loss of a small number of
devices, depending on how many devices each group contains and the
level at which the breakage occurred within the group.
In the case of a large number of devices (for example, very large line
arrays) it is advisable to use a mixed connection, dedicating a switch for
each line array and dividing it into groups of up to 8 devices, connected to
each other in a daisy chain.
Each device is equipped with a hardware bypass device of the network
that, in the event of a serious malfunction that involves the shutdown
of the internal logic, short-circuits the NET IN and NET OUT ports; in
this way, all the devices located downstream of the breakage will still be
controllable through INFINITY.
The system is able to compensate for
the breakage of 3 consecutive devices within each single daisy chain.
In order to ensure the correct operation of the system it is advisable to
use cables of category CAT5e or higher.
SN / SND UPGRADE PROCEDURE
Optional DANTE module installation (upgrade from SN / SND version)
•
Remove the rear panel
• Refer to the figure to locate the position of the card and the
correct orientation
• Lift the flat cable and gently press the card in alignment with the
connectors so that the PCB touches the screw columns
• Screw in the two fixing screws supplied
• Reposition the rear panel
• When switched on, the system detects the new “SND” version
which entails additional functions in the menu (related to
DANTE). By connecting the device to the network, the INFINITO
MANAGEMENT SUITE software detects the “SND” model
