or “straight” network cables. two LEDs above each
port indicate connection to a valid network (LinK)
and network activity (aCt).
Full information on connection of PLM Series prod-
ucts to a network is contained in the PLM Series
network Configuration Guide, included on the sup-
plied PLM Series installation CD-RoM. or available
as a download from www.labgruppen.com/plm.
primary connector
use this connector when the network is a simple
“star” configuration, consisting of individual Cat-5e
connections between PLM units and the local Eth-
ernet 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 PLM units 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 employ-
ing 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.
Mains connector
aC input to the PLM is via a neutrik PowerCon
®
connector, rated at 32 a. in the interests of safety,
nEVER disconnect the earth (ground) pin on the
mains cable (aC power cord).
software does not support this mode and therefore
bridged operation is not recommended. Please
contact plmsupport@labgruppen.com for further
information on bridge-mode operation.
Binding posts
in this version, the power outputs for loudspeaker
connection are available on four separate pairs of
fully-enclosed binding posts.
Speakon connectors
in this version, the power outputs are simultaneously
available on a single 8-pole neutrik Speakon connec-
tor, and on two 4-pole neutrik Speakon connectors.
the two 4-pole connectors carry the power outputs
of channels 1 & 2 and 3 & 4 respectively. the figure
below shows the proper wiring scheme for these
Speakon outputs.

7.2.3 Network Connectors
the two neutrik RJ45 Ethercon
®
connectors per-
mit integration into an Ethernet control network
encompassing multiple PLM Series units as well as
a PC running the Dolby Lake Controller PLM Edition
software. network connection permits full control of
all PLM functions, and monitoring of all PLM operat-
ing 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.
7.2.3.1 10/100Base-T Network Connections
the Ethernet ports automatically switch to operate at
the two standard Ethernet data rates of 10Base-t and
100Base-t, and also allow use of either “crossed”
