Chapter 2 Introduction Back Panel© 2012 Harmonic Inc. 18 Electra 1000, Version 3.0, Rev M2.10.3.1 Analog Audio Input PortsTwo Phoenix™ 1881480 6-pin connector ports support balanced or unbalanced stereoanalog audio input to the AIC.The connector that mates to the analog ports is a Phoenix 1881367 connector. SeeB.3.3 Analog Audio Input Ports on page 46 for pinout information.2.10.3.2 Digital Audio Input PortsTwo BNC ports support AES3 or S/PDIF to provide the stereo digital audio input to the AICmodule.2.10.4 Video Input PortsThe back panel contains up to four video input ports. These are BNC coaxial ports thatsupport standard definition serial digital video input or composite format.Each video input port connects internally to a video processing card (VPC) The videoprocessing cards are not visible from the encoder back panel.See 3.5.3 Connecting the Video Input Cables on page 25 for cabling instructions.2.10.5 IP Output PortOne 10/100/1000 Base-T Ethernet port provides two redundant IP output channels. The twoRJ-45 connectors are labeled GbE PRI and BKUP.The IP output port supports manual redundancy. The port also supports hot/warm standaloneredundancy: when the primary IP data channel detects a cable disconnection, the primarychannel stops outputting, and the backup channel takes over.In manual redundancy, you can enable one channel or both channels. If you enable onechannel, you must manually switch to the other channel after a service-affecting alarm. If youenable both channels, the encoder outputs the same data from both channels.See 3.5.4 Connecting the IP Output Cables on page 25 for cabling instructions. Set the IP addressand other network information for the IP output ports using NMX.2.10.6 Ethernet Management PortThe Ethernet management port, labeled ETH, is 10/100 Base-T and uses an RJ-45/UTP cableto connect to an Ethernet network. See 3.5.5 Connecting the Ethernet Management Cable onpage 25 for cabling instructions. See B.3.1 Ethernet Management Port on page 44 for pinoutinformation.2.10.7 Fault Relay PortThe fault relay port connects to a Form C relay that can switch up to 0.25 amps at 30 VDC.See B.3.2 Fault Relay/GPI Ports on page 45 for port pinout and additional information.The encoder energizes the fault relay during normal operation. The fault condition is indicatedin 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.
