Chapter 1
Overview
This manual supplement provides descriptions and operating instruction for
the
+EAS
Option available as an option on various new Cobalt
®
cards and
BBG-1000 standalone units, and as a purchased field-installed licensable
feature upload for the same models. Compatibility of this option for various
card and device models is indicated on the web page for the card or device.
+EAS Option Functional Description
(See Figure 1.) Option
+EAS
provides for automated keying Emergency Alert
System (EAS) text crawls in the active program video output. The function
receives its text stream via a card serial data input. The EAS crawl start can be
set to trigger upon receiving the serial data message, or be set to use a GPI to
trigger start of the EAS crawl.
Embedded in the received serial data are commands which set the message
severity to be shown by the keyed crawl (severity is correlated to
user-specified text color and background color for the crawl). User controls
allow control of the crawl speed and repeat of the crawl burn-in (if desired).

Read and understand the content of this supplement and all setup procedures
herein before implementing the Emergency Alert System (EAS) functions
described herein for practical use. Proper and expected EAS crawl insertion
must be manually observed and verified upon setup and subsequently during a
regularly scheduled EAS test (and optimally upon any actual emergency
communications). More information regarding EAS requirements and practices
are specified and promulgated in USC CFR 47 Part 11.
