L-NET network cabling

6.9.1 L-NET network overview
L-NET network is for transferring data to and from LA NETWORK MANAGER software (see the LA NETWORK
MANAGER User Manual [3.4]). It allows remote control and monitoring of a network of amplified controllers.
By using LA-PANEL, various digital network topologies such as daisy-chain, star, and hybrid are quickly and easily
configurable, allowing total flexibility in achieving the required system architecture. The star and hybrid network
topologies require the addition of a universal Ethernet
Note: The more reliable digital cabling scheme is the external star/internal star one.
 To cable L-NET network, use CAT5e U/FTP cables (or higher category) fitted with RJ45 connectors.
 The length of each network cable must not exceed 100 m/328 ft.
 Only connect network devices featuring a minimum speed of 100 Mbps.
IMPORTANT
6.9.2 Internal cabling
LA-PANEL features four RJ45 I/O sockets. When leaving the factory the LA-PANEL also features four CAT5e U/FTP
cables already installed. If cables replacement is needed follow the procedure described in [7.3].
The cable linked to the IN connector on the back of LA-PANEL allows network connection for all three LA8, following
two potential cabling schemes, illustrated in Figure 30:
- either by connecting a first LA8 via its L-NET IN connector, and routing the network towards another LA8 via the L-
NET OUT connector, for a daisy-chain topology;
- or by connecting the cable to a switch (not provided), which will feed all three LA8, for a star topology.
The cable linked to the OUT connector on the back of LA-PANEL allows getting back the network signal from the L-
NET OUT connector of a LA8, to send it towards another LA-RAK and set up an external daisy-chain topology.
