 Every line input supports two (2) EAS decoders. The left side of the input is decoded
separately from the right side. So two line inputs provide four (4) EAS decoders.
 EAS alerts are selectively played out of the analog line output ports. Software is used to
select which ports are used for alert origination and forwarding.
 The main microphone input is used to record EAS audio messages.
For decoding, each side of the stereo input of any audio input can be selectively used as a
single decoder source. In other words, one stereo input supports two EAS decoders. A dual
RCA to 3.5 mm jack input adapter can be used to connect two separate mono input signals to
a One-Net
SE
line input jack.
For alert encoding an audio cable is run from a software-selected 3.5 mm line output jack
into your systems alert audio wiring. Only analog audio output is supported.
2.5 Video Wiring
The video output provides an NTSC analog composite video signal through the yellow RCA
jack. This will provide a details page during alert forwarding and/or alert origination.
2.6 GPIO Output relays
The One-Net
SE
provides two General Purpose Output relays and two General Purpose inputs.
During an alert origination or forwarding, the GPO relay 1 is closed for the duration of the
alert audio portion of the alert, and GPO relay 2 can be programmed to close during the audio
or video portion of the alert.
2.7 MPEG Encoder Card Wiring
For One-Nets equipped with the optional MPEG2 Encoder card, see the illustration below for
wiring the MPEG2. The video output needs to be loop cabled back into the video input of the
Encoder card. Likewise, one audio output needs to be cabled to the MPEG audio input port.
Optional MPEG2 PCI Encoder Card Audio/Video connections
NOTE: The SPDIF digital audio output port is not used.
