Controls, Indicators and Connections
Ethernet Ports
The two locking Ethernet ports on the back of the device are labelled
‘Primary’ and ‘Secondary’ and are used for AoIP connectivity and to provide
power to the device via Power over Ethernet (PoE) on the AVN-CU2 or PoE+
on the AVN-CU4. PoE/PoE+ can be provided via a supporting network
switch or by using a PoE/PoE+ injector.
The two ports can be configured to function in either redundant or
switched mode, via the Dante Controller interface. Selecting redundant
mode allows the two ports to be connected to separate networks, this
means that if one network fails, the other network will be used instead; in
this case a separate address is given to each port. Selecting switched mode
allows devices to be daisy chained allowing the secondary port to be used
by another AoIP device in order to communicate on the network; in this
case only the ‘Primary’ port is given an address.
Each Ethernet port has two LED indicators. The LED located to the top-left
of the port indicates the link state, this is green when the connection is
operating at 1 Gbps, orange when operating at 100 Mbps, and off when
operating at any other speed. The LED located to the top-right of the port
flashes if data is being transmitted/received on the port, the rate of the
flashing varies depending on the rate of data transmission.
Both Ethernet ports are locking in order to prevent accidental removal of
any connections. In order to remove a connector, the ‘PUSH’ button should
be held whilst removing the connector.
SFP Ports
The SFP (Small Form-factor Pluggable) connector allows an alternative
interface type (for example fibre) to be used for each network port. If an
SFP interface is used, the corresponding RJ45 port cannot be used for
network communications at the same time however, the RJ45 port can still
be used to provide PoE/PoE+ functionality.
Audio Inputs
Stereo Analogue/Digital Input
This RJ45 input can be configured as either analogue or digital via the
embedded web server (this input is only digital on the AVN-CU4). The port
uses a St compatible pinout as follows:
• Pin 1: Left+/AES3+
• Pin 2: Left-/AES3-
• Pin 3: Right+
• Pin 4: Ground
• Pin 5: No Connection
• Pin 6: Right-
• Pin 7: No Connection
• Pin 8: +12V
Inputs A, B, C and D (AVN-CU4-DANTE only)
These inputs are analogue inputs on locking female XLR connections. The
inputs have the following pinout:
• Pin 1: Ground
• Pin 2: Input+
• Pin 3: Input-
+12V DC Input
This 4-pin connector allows an ex12V DC power supply to be used to
power the unit. The connection has the following pinout:
• Pin 1: Ground
• Pin 2: +12V (Legacy)
• Pin 3: N/C
• Pin 4: +12 V
