6.2.3 Network connectors

The two Neutrik RJ45 EtherCon
passing multiple PLM Series units as well as a PC running the Lake Controller software. Network connec-
tion permits full control of all PLM functions, and monitoring of all PLM operating parameters, from a remote
position. The PLM Series also supports the Dante audio networking protocol, which allows transmission of
multichannel, high-definition digital audio over the same Ethernet connection.
The Ethernet ports automatically switch to operate
at the two standard Ethernet data rates of 10Base-T
and 100Base-T, and also allow either "crossed" or
"straight" network cables to be used. Two LEDs
above each port indicate connection to a valid network (LINK)
and network activity (ACT).
Full information on how to connect the PLM to a network
is contained within a separate document, the PLM Series
Network Configuration Guide.
Primary connector
Use this connector when the network is a simple "star" configuration, consisting of individual Cat-5e
connections between PLMs and a local Ethernet switch. Alternatively it can be used to connect to the
Secondary connector of another PLM within a network, thus forming a daisy-chain topology.
Secondary connector
The secondary network connector can be used as a loop-through to daisy-chain multiple PLMs into the
network. Alternatively, system security can be greatly increased by using a dual-network topology. In this
case, the Secondary connector is connected to an alternative Ethernet distribution system employing a
second set of switches, thereby ensuring full redundancy and no single point-of-failure in the case that
Dante is used and a switch or cable fails. Further information on PLM network configurations can be found
in the PLM Series Network Configuration Guide.
When connecting multiple PLMs to an Ethernet
network, care must be taken NOT to create a ring
(closed loop) with the PLM Ethernet ports. Ethernet
by default will not support a ring topology; creating a
ring will cause the network to malfunction.
