2.10.3.1
Analog Audio Input Ports
Two Phoenix™ 1881480 6-pin connector ports support balanced or unbalanced stereo
analog audio input to the AIC.
The connector that mates to the analog ports is a Phoenix 1881367 connector. See
B.3.3 Analog Audio Input Ports
on page 46 for pinout information.
2.10.3.2
Digital Audio Input Ports
Two BNC ports support AES3 or S/PDIF to provide the stereo digital audio input to the AIC
module.
2.10.4
Video Input Ports
The back panel contains up to four video input ports. These are BNC coaxial ports that
support standard definition serial digital video input or composite format.
Each video input port connects internally to a video processing card (VPC) The video
processing cards are not visible from the encoder back panel.

2.10.5
IP Output Port
One 10/100/1000 Base-T Ethernet port provides two redundant IP output channels. The two
RJ-45 connectors are labeled GbE PRI and BKUP.
The IP output port supports manual redundancy. The port also supports hot/warm standalone
redundancy: when the primary IP data channel detects a cable disconnection, the primary
channel stops outputting, and the backup channel takes over.
In manual redundancy, you can enable one channel or both channels. If you enable one
channel, you must manually switch to the other channel after a service-affecting alarm. If you
enable both channels, the encoder outputs the same data from both channels.
3.5.4 Connecting the IP Output Cables
on page 25 for cabling instructions. Set the IP address
and other network information for the IP output ports using NMX.
2.10.6
Ethernet Management Port
The Ethernet management port, labeled ETH, is 10/100 Base-T and uses an RJ-45/UTP cable
to connect to an Ethernet network. See
3.5.5 Connecting the Ethernet Management Cable
page 25 for cabling instructions. See
B.3.1 Ethernet Management Port
information.
2.10.7
Fault Relay Port
The fault relay port connects to a Form C relay that can switch up to 0.25 amps at 30 VDC.
See
on page 45 for port pinout and additional information.
The encoder energizes the fault relay during normal operation. The fault condition is indicated
in the same way as the encoder’s powered-off condition, which is with the relay de-energized.
You can use this method to correctly identify a power supply failure or loss of input power.
The signals are normally open or normally closed.
NOTE:
Any alarm causes the fault relay to change to the fault state. When multiple alarms accumulate,
all alarms must be active for the relay state to change.
