The +12V supply is fused and has a maximum output current of 200mA.
GPIO ports can be set up as GPO or GPI. GPO are open collector, this means
the output pin is connected to ground when the GPO is active. GPI are
active low this means they are triggered when pulled down to ground. GPIO
configuration can be managed through the devices embedded web server.
Network Interfacing RJ45 Connections
In an ideal installation, the lower port should be connected to a dedicated
network switch that handles audio and audio related traffic only. All
other AoIP sources and destinations, and grandmaster clocks should be
connected to this network. The upper port can then be connected to a
separate network to provide access to the embedded web server. With this
setup, potentially heavy network traffic on a company LAN does not affect
the performance of the AoIP network.
Ethernet
All devices in the AVN portal series have a female RJ45 used for network
interfacing, this is the top port and is used to access the devices embedded
web server.
AoIP
All devices in the AVN portal series have a female RJ45 used for audio
transfer and network interfacing, this is the bottom port and is used
primarily to transfer audio across a network, however it can also be used to
access the devices embedded web server.
SFP Interface
AoIP
All units in the portal series are fitted with an SFP (Small Form-factor
Pluggable) port this allows the user to install a SFP transceiver of their
choice such as a 1Gbit/s copper or optical SFP transceiver. The AoIP
network interfacing RJ45 connection cannot be used at the same time as
the SFP interface.
12V DC Input
This 4-pin connector allows an ex12V power supply to be used
to power the unit. Both the 12V DC input and the mains AC input can be
connected at the same time, this provides redundancy if needed.
Mains Fuse
This 20mm x 5mm anti-surge mains fuse is rated at 2A.
Mains AC Input
This universally filtered IEC is the mains AC input power supply to the unit.
