EAS
The Anywave Encoder can automatically detect an Emergency Alert System (EAS)
signal from an external EAS generator and switch all channels to the Video/Audio signal
of the EAS generator.
To enable this feature do the following:
1) Connect the CVBS video and stereo audio output of an EAS generator to the
EAS input of the Anywave Encoder (Composite video and stereo audio)
2) Start the EAS channel (last channel on the control page)
3) Check that the EAS channel is running (on the control panel the input signal
should be green. The status information will show an active video and audio
signal encoding (just like other channels))
Some EAS generators have test modes. We recommend testing your Anywave encoder
with your EAS generator signal to be sure all connections and setup are correct.
When an EAS alert occurs, the Anywave encoder detects the alert tone on the EAS
input, then automatically switches all encode channels to the EAS signal. Therefore, all
channels will have the same EAS video and audio signal. When the EAS signal alert
ends with a second alert tone, then the Anywave encoder will switch back to the normal
signal programming.
