CONNECTORS
XLR connectors allow connectivity to an analog audio source. This input can be used as a back-up to
CobraNet™ or as a primary audio source in the absence of CobraNet™.
8) AUDIO IN
a) F-XLR Active 20K Ohm Balanced, 10K Ohm Unbalanced, PIN 2 HOT.
9) AUDIO OUT
a) M-XLR Passive Audio Pass-through.
10a & 10b) CobraNet™ PRIMARY and SECONDARY NETWORK CONNECTORS
a) The dual RJ-45 CobraNet™ connectors allow a Primary & Secondary connection to the 100Mb Ethernet
network and provide device control and monitoring as well as CobraNet™ digital audio on the same
CAT5 cable. Should the Primary connection (10a) lose Link activity with the network, the DPCN will
automatically switch to the Secondary connection (10b) to ensure uninterrupted audio and control/
monitoring. Use the Primary connector as your main CobraNet™ and Ethernet port.
NOTE: These dual RJ-45 connectors CANNOT be used to daisy-chain Ethernet cables. An external
Ethernet Switch is required to “distribute” Ethernet connections. See Section 7 for details.

device by the manufacturer and is not changeable by the user. This unique physical address
enables each device on the network to identify and communicate directly with other devices
connected to the network.
