DASDEC II Hardware and Software Specifications

An Emergency Alert System Analog/Digital Encoder/Decoder Platform

The DASDEC II is a State-of-the-Art Emergency Alert System (EAS) Analog/Digital Encoder/Decoder platform. First
introduced in 2005, this system is being deployed around the United States in a wide variety of Cable, Broadcast, IPTV,
and Emergency Operation facilities. The DASDEC II is built with the latest digital PC computer technology. The DASDEC
encoding/decoding technology is software based, and is built upon the Linux OS. The DASDEC II core hardware is a
standard PC motherboard and digital audio sound cards. The DASDEC II is easy to upgrade, not requiring custom ROMS.
The DASDEC II also exploits the benefits of modern network technology. It is fully operable over a LAN using secure
network protocols. In addition, it supports existing methods of device control using a serial port. The DASDEC II is
representative of the continuing advance of PC hardware into technological areas that only a few years ago required
custom hardware.
