Connection And Setup; Nomadlink Network Cable Lengths - Lab.gruppen FP+ Series FP 10000Q Operation Manual

Up to 60 amplifiers can be connected to one NLB
60E in a daisy-chain or closed loop.
When the NLB 60E is powered up, the NomadLink
network receives phantom power. This causes the
blue NomadLink LED on the amplifier front panel
and the NomadLink LED on the rear panel to light
up. NomadLink is active even when the amplifier has
mains power disconnected or is not yet powered
up.
The amplifier does not have a stand-by power
supply for the network. The network is solely
powered from the NLB 60E. Should an amplifier fail
or be inadvertently disconnected from the mains,
network integrity is fully maintained and all amplifiers
remain visible on the system.

7.7.2 Connection and setup

The NomadLink network requires use of an NLB
60E NomadLink Bridge & Network Controller. The
NomadLink network is established by connecting the
NLB 60E OUT port to the first amplifier's IN port.
Then a daisy-chain is established by connecting the
first amplifier's OUT port to the next amplifier's IN
port, and so on. If a closed loop network is desired
for improved redundancy (highly recommended), the
last amplifier's OUT port must be connected to the
NLB 60E's IN port.
For all connections, straight Cat-5 RJ45-equipped
Ethernet cables should be used.
OPERATION AND PERFORMANCE 7
Optimal NomadLink performance can only
be assured when using Cat-5 cables.
However, as NomadLink is only using two
wires + ground for communication and
phantom power it is possible to create converters
from RJ45 to, for example, XLR connectors using
2-wire shielded cable. The NomadLink network can
then be operated using a standard tie-line in a
multicore signal distribution system. See the drawing
below for an example of how to create a
converter.
If any cable format or connection other than
Cat-5 (or better) and RJ45 is utilized,
network performance may be compro-
mised. In this event Lab.gruppen cannot
guarantee that the NomadLink network will be fully
operational.

7.7.3 NomadLink network cable lengths

In situations where the amplifiers and the NLB 60E
will be positioned in different locations at some
distance from each other, or where groups of
amplifiers within a single subnet with up to 60 units
will be installed with a distance in between, these
general rules may be considered:
