conditions. Over seventy percent of all EAS and EBS activations were a result of natural
disasters and were weather related. Linking NOAA Weather Radio digital signaling with
the EAS digital signaling will help NWS save lives by reaching more people with timely,
site-specific weather warnings.
FEMA provides direction for state and local emergency planning officials to plan and
implement their roles in the EAS.
What you need to do as a Broadcaster
The encoder/decoder allows your facility to decode EAS alerts originated from alert
sources in your area. These sources can be radio, TV, and cable TV stations. These
stations can be forwarding alerts received from a web of broadcasters, or originating
alerts if designated as a primary source.
To meet minimum requirements of the FCC,
you must send randomized weekly tests, forward monthly tests, and forward Nation
-
al alerts
. Your state and local EAS plan may also impose other requirements.
A good source of information is the EAS website at
https://www.fcc.gov/general/
emergency-alert-system-eas
. The FCC provides handbooks in Adobe PDF format for AM
and FM radio, for TV and for Cable TV.
PERIPHERALS
The One-Net/DASDEC supports many peripheral devices, from character generators to
printers. As of this release, the EAS device can replace most commercial EAS encoder/
decoder units, depending upon the peripheral hardware to which they have been
connected.
Monroe Electronics Cable Envoy and CEMS 500/1000
The EAS device directly supports Monroe Electronics Cable Envoy multi-channel analog
video CG and the CEMS 0500/1000 single channel analog video crawl overlay keyer.
The Cable Envoy interacts with and acts as a controller for the EAS device. For instance,
it controls running audio from the EAS device. The CEMS unit is a basic CG to which
the EAS device can send text crawl commands. Both Monroe units require a straight
through RS-232 cable. The Monroe CEMS requires a valid TV license key. See EAS

.
Keywest VDS-830/840/Starmu/Star-8
The EAS device directly supports the single channel analog Keywest Technology VDS-
830 and 840 character generator units. These units require a NULL modem RS-232
cable. The EAS device can crawl alert text on the VDS as well as provide severity color
coded backgrounds. The VDS-830 cannot key the crawl over a video background. It
will the full page with a gray background. The VDS-840 can key the crawling text over
live video. The EAS device also has modes to support the Starmu and Star-8 CG’s. This
option requires a valid TV license key. See

.
Chyron CODI
The EAS device can replace systems that operate Chyron CODI character generators.
The EAS device supports both the analog CODI as well as the Digibox CODI. The EAS
device can crawl alert text overplayed on live video on these units. The Digibox CODI
provides SDI digital video input and output. The EAS device also supports simultaneous
network based control of multiple CODI Digibox units that provide a built-in LAN port.
