5.7.2. 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 rst amplier’s IN port. Then a daisy-chain

is established by connecting the rst amplier’s OUT port to the next amplier’s IN port, and so on. If a closed

loop network is desired for improved redundancy (highly recommended), the last amplier’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.

TIP: 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.

NOTE: If any cable format or connection other than Cat-5 (or better) and RJ45 is utilized, network

performance may be compromised. In this event LAB GRUPPEN cannot guarantee that the

NomadLink network will be fully operational.

5.7.3. NomadLink network cable lengths

The connection between the NLB 60E and your PC is a standard Ethernet network running the TCP/IP protocol.

Cable distances between NLB 60E and your PC follow standard rules for Ethernet systems.

In situations where the ampliers and the NLB 60E will be positioned in different locations at some distance from

each other, or where groups of ampliers within a single subnet with up to 60 units will be installed with a distance

in between, these general rules applying to Ethernet cabling limitations may be considered.

• Rule 1: The maximum cable length in between any two devices may not exceed 300 meters / 980 feet.

• Rule 2: In a non-closed-loop daisy-chained subnet the total maximum cable length is 400 meters / 1300 feet.

• Rule 3: In a closed-loop subnet the total maximum cable length is 700 meters / 2300 feet.
