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 con-
nected to the network and remotely controlled.
With the WINK function present on the INFINITO software, the LED fla -
shes allowing the association between the virtual device in the PC work-
space and the physical device.
There are 3 ways to connect to the network:
• Star connection: it is possible to connect each speaker individual-
ly 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 invol-
ves 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.
• 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. Sim-
ply 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.
• 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 phy-
sical 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 ar-
rays) 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 con-
trollable through INFINITY. The system is able to compensate for the
breakage of
3 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.
N / ND UPGRADE PROCEDURE
Optional DANTE module installation (upgrade from N / ND version)
•
Disassemble the amplification module from the speaker cabinet
• Remove the plastic cover
• Refer to the figure to locate the position of the card and the cor-
rect orientation
• Gently press the card in alignment with the connectors so that
the PCB touches the screw columns
• Screw in the two fixing screws supplied
• Refit the plastic cover and tighten the module to the cabinet
• When switched on, the system detects the new ‘ND’ version which
entails additional functions in the menu (related to DANTE). By con-
necting the device to the network, the INFINITO MANAGEMENT
SUITE software detects the ‘ND’ model.
