Digital Alert Systems, LLC - DASDEC 1.0 Users Manual 4 2.The Emergency Alert System 2.1.Purpose According to the FCC, "The EAS is designed to provide the President with a means to address the American people in the event of a national emergency. Through the EAS, the President would have access to thousands of broadcast stations, cable systems and participating satellite programmers to transmit a message to the public. The EAS and its predecessors, CONELRAD and the Emergency Broadcast System (EBS), have never been activated for this purpose. But beginning in 1963, the President permitted state and local level emergency information to be transmitted using the EBS." But the EAS system is used for much more than to support a method of communication that has never been (and hopefully never will be) used. The EAS system provides state and local officials with a method to quickly send out important local emergency information targeted to a specific area. This includes weather alerts as well as other local emergency alerts such as child abductions and disasters. The EAS system also has test alerts which are run on a weekly and monthly basis in …

The signal is brought into the EUT on the Audio Line In port and, after processing, is output the Audio Out/Speaker ports. The unit has Ethernet and serial ports for control purposes. A parallel printer port is available for logging purposes. USB and Composite video ports are available for expansion purposes, although, at this time the expansion is undefined. Monitor, mouse, and keyboard ports are not typically connected, but on occasion may be and for this testing these devices were attached to the EUT. Two versions of the DASDEC-1EN were tested. The difference is in the main processor board and the sound card. The tables below show the internal configurations of the DASDEC-1EN devices tested. The worst-case emissions were seen during testing of the configuration with the VIA ME6000 main board and the results in this report are from testing this configuration. 600 MHz System Component Description VIA ME6000 Main computer board and processor FSP Group FSP150-50PL Power supply Speaker Internal speaker Maxtor 20 GB Hard drive Matrix Orbital LCD Display Display module Seal SSC-2 Sound Card COMMUNICATION CERTIFICATION LABORATORY TEST REPORT: 73-7972 ISSUE DATE: 06/01/2004 Page 6 of 34 1000 MHz System Component Description VIA ME10000 Main computer board and processor FSP Group FSP150-50PL Power supply Speaker Internal speaker Maxtor 30 GB Hard drive Matrix Orbital LCD Display Display module Soundblaster PCI 16 Sound Card 2.3 EUT and Support Equipment: The FCC ID numbers for all the EUT and support equipment used during the test (including inserted cards) are listed below: Brand Name Model Number Serial No. FCC ID Number Description Name of Interface Ports / Interface Cables BN: DAS MN: DASDEC-1EN (1) N/A EAS Encoder/ Decoder See Section 2.3 BN: CA MN: Speakers N/A Speakers Audio/Unshielded cable with stereo mini-jack connector (2) BN: Gateway MN: EV500A SN: 15017A444139 BEJCB575B Monitor Video/Shielded attached video cable (2 & 4).

©Digital Alert Systems, LLC 2004 Page 1 DASDEC Compliance to FCC EAS Encoder/Decoder requirements in Part 11.32, 11.33, and 11.34 Digital Alert Systems,LLC - July 2004 Introduction The DASDEC-1EN is a new kind of Emergency Alert System Encoder/Decoder platform. This is because it is built with the latest digital PC computer technology, instead of from custom electronic boards and circuits. The DASDEC encoding/decoding technology is software based, and is built upon the Linux OS. The DASDEC core hardware is a standard PC motherboard and digital audio sound cards. The DASDEC 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 or ports. The DASDEC is representative of the continuing advance of digital device technology into technological areas that only a few years ago required custom hardware. Compliance Statements What follows is an item-by-item list of the FCC regulations for EAS Encoders and Decoders and how the DASDEC-1EN complies with each regulation. Note: As an aside, a method to incorporate text transmission techniques into the EAS protocol as referenced the 2001 NPRM and the 2002 R&O has been developed by Digital Alert Systems, LLC and is available in the DASDEC if this methodology is accepted. Please reference www.digitalalertsystems.com for information on this methodology. 1994 R&O and FNPRM Adopted: Nov. 10, 1994 Released: Dec. 9, 1994 R&O 12-9-94 ENCODER 11.32 EAS Encoder. (a) EAS Encoders must at a minimum be capable of encoding the EAS protocol described in 11.31 and providing the EAS code transmission requirements described in 11.51. EAS encoders must additionally provide the following minimum specifications: The DASDEC encodes messages into digital audio files (WAV format) using 16000 samples a second. Each encoded file may be played out of an analog audio output port from the sound card (s) into a transmitter or into an EAS decoder. These files are distortion free because they are mathmatically computed. The audio quality of the soundcards is excellent and works well for the purpose of EAS encoding. Reliable communications with the TFT 911 and SAGE Endec, both certified EAS encoder decoder packages, attest to the accuracy of DASDEC EAS encoding. The audio files exactly encode messages in the format described in 11.31 as follows: [PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL- (one second pause) (HEADER repeated three times) (transmission of 8 to 25 seconds of Attention Signal) as described in 11.51 (transmission of audio, video or text messages) alert or test audio and text messaging [PREAMBLE]NNNN (END of MESSAGE repeated three times) ©Digital Alert Systems, LLC 2004 Page 2 (1) Encoder programming. Access to encoder programming shall be protected by a lock or other security measures and be configured so that authorized personnel can readily select and program the EAS Encoder with Originator, Event and Location codes for either manual or automatic operation. DASDEC encoder access is via a Web browser interface. The DASDEC acts as a Web server and provides pages for configuration, monitoring, and operation. The interface is available to any HTTP browser, which can access the network to which the DASDEC belongs. Alternately, the same interface can be run directly upon a VGA monitor connected to the DASDEC. The Web interface provides a login page that is password protected. It can be set to use secure socket protocols, and is readily accessible to authorized personnel. The DASDEC is further secured in that it provides a password protected login shell on a VGA monitor and keyboard directly connected to its back plane connectors. The DASDEC is very easy to program EAS alerts because it presents a graphical interface for all required operations on a single page. Since the DASDEC is accessible to computer workstations via a network, simply by using a browser on a workstation, an operator does not have to be physically present at the device in order to encode and send EAS alerts, but he must have the authorizing password…
