Input / Output Connectors (Cont.)
Inputs:
Line In:
This is a balanced analog input that is used for bypassing the CobraNet system and inserting an
analog audio signal directly into the self-powered loudspeaker. If CobraNet is functioning, this
signal will be summed with the CobraNet signal being received on Ch 1. In the CobraNet
Breakout Box, this connector has no function.
CNet (CobraNet):
This is a balanced analog input used for inserting an audio signal onto the CobraNet network.
This can be used for sending a signal from the location of the loudspeaker or breakout box to
another location in the facility.
Outputs:
Ch 1 through Ch 6:
These are balanced analog audio outputs from the CobraNet network. Their purpose is to
eliminate the need for more than one CobraNet network module or Breakout Box in all but the
largest clusters and systems. The Ch 1 output is the same signal that is routed internally to the
self-powered loudspeaker.
Indicators:
CobraNet (Ethernet) RJ-45 LEDs:
On each of the RJ-45 Ethernet conn
ectors are two LEDs. If the Primary connector is being
used, then the LEDs on this connector will show activity. The same is true for the secondary
connector.
The left LED on the RJ-45 will either glow steadily or flash. This LED will be flashing when it
is the conductor. When it is in use it will glow steadily.
The right LED on the RJ-45 will either be green or orange. Green indicates the unit has a link.
Orange indicates a fault condition.
Sig (Signal Present) LED:
This is the signal present LED. It will indicate when the Ch 1 output has audio present.
Unit Identification
In order for the CobraNet units to communicate on the Ethernet network, a unique address must be
supplied to each device.
Mac Address
Each CobraNet unit has a unique MAC Address. This MAC address number is affixed to each
CobraNet product with either a sticker or a tag. The MAC Address number, for example, should
look something like 0062b02319e. It is important to save this number because it will help aid in
identifying a particular CobraNet unit during set-up and configuration.
