Use the primary connector when using a star network topology, consisting of individual Cat-5e connections
between the devices and an Ethernet switch. Alternatively this connection can be used to daisy chain directly to
another LAKE Processor. The daisy chain topology should not be used with Dante.
For a technical reference of the Ethernet Port, please refer to section 7.3 of the LM Series Operation Manual.
Additional information is also available in the LAKE Network Configuration Guide.
NOTE: The Ethernet ports automatically switch to operate at Ethernet data rates of 100 Mbps or 1000
Mbps, and allow straight or crossed network cables. Two LEDs above each port indicate valid network
connection (LINK) and network activity (ACT).
Secondary Connector - The secondary network connector can be used to daisy-chain multiple LM & PLM
5
Series and legacy Dolby and LAKE devices. Alternatively, a Dante dual-network topology can be created by
connecting all secondary network connectors to a separate Ethernet switch, ensuring full redundancy in the event
of a network component failure.
NOTE: Additional processor configuration is required for a dual redundant network setup. See the
LAKE Controller Operation Manual for further details.
For a technical reference of the Ethernet Port, please refer to section 7.3 of the LM Series Operation Manual.
Additional information is also available in the LAKE Network Configuration Guide.
NOTE: When connecting multiple devices to an Ethernet network, care must be taken NOT to create a
closed loop which causes network malfunction.
GPIO Connector - A 9-pin GPIO (General Purpose Input Output) connection is provided to enable integration
6
with external systems such as alarm/fire systems, providing basic control of power state, mute along with fault
notification to an external monitoring system. Please refer to sections 6.9.4.4 and 7.4 of the LM Series Operation
Manual for further details.
Mains Power Connector - A universal power supply capable of accepting 70-265 V ~ 50-60 Hz : 25 W is
7
built into LM Series devices. The IEC power cable provided includes a locking feature via a pin on the bottom of the
connector; the connector can accept standard or locking IEC power cables.
The power supply must be connected to AC mains using a power cable with a correctly wired plug for the
country of operation.
