Audio Outputs
Stereo Analogue/Digital Output
This RJ45 output can be configured as either analogue or digital via the
embedded web server (this output 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: Cough GPI
• Pin 6: Right-
• Pin 7: No Connection
• Pin 8: +12V
An AVN-HA1 or AVN-HD1 can be connected to this output, the AVN-HA1
or AVN-HD1 can then be used to control the cough GPI pin.
Outputs A, B, C, D, E and F (AVN-CU4-DANTE only)
These outputs are analogue outputs on male XLR connections. The outputs
have the following pinout:
• Pin 1: Ground
• Pin 2: Input+
• Pin 3: Input-
GPIO Connector
The AVN-CU2-DANTE has a single female D-Sub (DA-15) connection, this
provides 10 configurable GPIO and a voltage free switching relay contact.
The connection has the following pinout:
• Pin 1: GPIO Port 1
• Pin 2: GPIO Port 2
• Pin 3: GPIO Port 3
• Pin 4: GPIO Port 4
• Pin 5: GPIO Port 5
• Pin 6: Relay – Normally Open Contact
• Pin 7: Relay – Normally Closed Contact
• Pin 8: Relay – Common
• Pin 9: GPIO Port 6
• Pin 10: GPIO Port 7
• Pin 11: GPIO Port 8
• Pin 12: GPIO Port 9
• Pin 13: GPIO Port 10
• Pin 14: Fused (50 mA) +12V DC Supply
• Pin 15: Ground
The +12V DC supply is fused and has a maximum output current of 50 mA.
GPIO ports can be set up as outputs (GPO) or inputs (GPI). GPO are open
collector, this means the output pin is connected to ground when the GPO
is active. GPI are active low and are triggered when pulled down to ground.
GPIO configuration can be managed through the devices embedded web
server.
AC Power Connection (AVN-CU4-DANTE only)
This universally filtered IEC is the mains AC input power supply to the unit.
Mains Fuse (AVN-CU4-DANTE only)
This 20 mm x 5 mm anti-surge mains fuse is rated at 2A.
Reset Button
On the AVN-CU2-DANTE, the recessed reset button is situated to the right
of the secondary Ethernet connection.
On the AVN-CU4-DANTE the button is situate to the right of the mains AC
input. A short press of the button will reboot the device leaving the
configuration unaffected. Pressing and holding the button for 10 seconds
will reboot the unit into recovery mode which can be used to install new
device firmware.
