This initial setup should be performed by or at least with the assistance of your Engineering department. It is important that the initial programming is done properly. PART 1: SYSTEM SETUP. STEP 1: GETTING TO THE STATION SETUP SCREEN. The first step is configuring the EAS unit. To enter the setup, go to the menu bar click on Config, then on Station Setup. This will take you to the station setup screen. . STEP 2: Identifier. Enter the station callsign in the upper left field. This must be 8 characters long. Fill any unused spaces with slashes "/" (required). STEP 3: Input Alias(s). Fill in the sources name you are receiving on the analog inputs. This step is optional but is recommended. STEP 4: Message Timeout. This is the recording timeout in seconds for received EAS messages (required). 120 seconds is typical. STEP 5: UTC Comp. This is the difference between universal time and your time zone in hours (required). STEP 6: Home FIPS. This is your home county (required). This the state code plus county code. Example: Say a station is licensed to New York, New York....New York's state code is 36. New York's county code is 061. So the code is 0+36+061 or 036061. A list of FIPS codes is available at this website: http://www.epa.gov/enviro/html/codes/state.html You may also obtain your county code from PART 2 on the next page. STEP 7: EAS Originator Code. This is a three-letter code assigned to the type of facility (required). A broadcast station would use EAS. The National Weather service uses NWS. Other government agencies use CIV. STEP 8: 2-Tone Length. This is the length in seconds of the two-tone attention signal (850Hz and 953 Hz) transmitted during alerts. At the time of this writing, 8 seconds is required. PART 2: COUNTY SETUP. STEP 1: GETTING TO THE EVENT/FIPS SETUP SCREEN. This is the second part is configuring the EAS unit. To enter the setup, go to the menu bar click on Config, then on Event/FIPS Setup. This will take you to the setup screen (see picture below). You will first want to adjust the priority of the Event Codes (optional). This is done on the right-hand pane. Click on the item(s) you want to adjust so it is highlighted in blue, select the Priority from the drop-down, and then press Change Priority of Selected. For example in most areas, a Tornado Warning would be second-highest priority after a national level emergency (EAN) which is a 1 priority. We suggest setting TOR (Tornado Warning) to a priority of 2. A priority of 0 means no automatic action will be taken, but it will be logged. STEP 2: Adding Counties to Event Codes. In this step you must highlight the Event/Priority codes on the right that you want your system to respond to (you may hold CTRL key to select multiple one, and/or you may drag to select all of them. Next, on the upper left, select a State and then select a County in your coverage area. Lastly, press the Add County Code + Event Code + Priority button to add them to the list on the lower left (see picture below). You will need to change the county and press the Add button for all counties in your service area. Congratulations! You have completed the software setup part of the instructions. Your system is almost ready to be put into operation. Audio Wiring: Note: Static Sensitivity: Some of the devices contained in unit are susceptible to static discharges. Appropriate static control procedures should be employed at all times when servicing. All devices connected to the unit should be grounded. For example, a properly grounded three-prong outlet is probably acceptable. In the event that the device does not have a proper grounding plug, a #12 or #14 stranded grounding wire should be added to the device in a “star” configuration. Many stations neglect to connect their satellite receivers, dishes, cable modems, DSL lines and etc to a common ground system. Because of the potential for lightning damage, all of the devices really need to be connected to a “star-type” common ground. In addition, a UPS with power, telephone, antenna, and Ethernet protection is strongly urged. Installation: The basic components of installation are the Audio …

The decoding/encoding status of EAS messages is shown on VGA monitor. Two serial ports and a network interface are provided for operational control. § 11.31 EAS protocol (a) The EAS uses a four part message for an emergency activation of the EAS. The four parts are: Preamble and EAS Header Codes; audio Attention Signal; message; and, Preamble and EAS End Of Message (EOM) Codes. The Unit complies with 11.31() for EAS protocol. During transmissions, this is generated digitally within software and outputted via a sound card. The unit is also capable to receiving the EAS protocol via audio card inputs, and complies with the revised provisions for expanded codes. To test overall compliance, a series of tests were transmitted and received to and from several commonly commercially available EAS Encoder/Decoder Units (Holly-Anne model HU-961, Sage model 1822, Gorman-Redlich model EAS-1). These tests served as a "double-check" of compliance and real-world compatibility with the EAS Protocol. These tests were conducted during September 2012. (1) The Preamble and EAS Codes must use Audio Frequency Shift Keying at a rate of 520.83 bits per second to transmit the codes. Mark frequency is 2083.3 Hz and space frequency is 1562.5 Hz. Mark and space time must be 1.92 milliseconds. Characters are ASCII seven bit characters as defined in ANSI X3.4-1977 ending with an eighth null bit (either 0 or 1) to constitute a full eight-bit byte. See attached pictures of header FSK tones as captured from audio output, as viewed in Cool Edit audio editor program. (2) The Attention Signal must be made up of the fundamental frequencies of 853 and 960 Hz. The two tones must be transmitted simultaneously. The Attention Signal must be transmitted after the EAS header codes. See attached pictures of two-tone attention signal as captured from the units audio output, as viewed in Cool Edit audio editor program. (3) The message may be audio, video or text. (b) The ASCII dash and plus symbols are required and may not be used for any other purpose. Unused characters must be ASCII space characters. FM or TV call signs must use a slash ASCII character number 47 (/) in lieu of a dash. (c) The EAS protocol, including any codes, must not be amended, extended or abridged without FCC authorization. The EAS protocol and message format are specified in the following representation. Examples are provided in FCC Public Notices. [PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL-(one second pause) [PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTTpJJJHHMM-LLLLLLLL-(one second pause) [PREAMBLE]ZCZC-ORG-EEE-PSSCCC+TTTT-JJJHHMM-LLLLLLLL-(at least a one second pause) (transmission of 8 to 25 seconds of Attention Signal) (transmission of audio, video or text messages) (at least a one second pause) [PREAMBLE]NNNN (one second pause) [PREAMBLE]NNNN (one second pause) [PREAMBLE]NNNN (at least one second pause) See attached pictures of relayed Required Monthly Test as captured from audio output, as viewed in Cool Edit audio editor program (If a higher resolution jpeg file is required please contact us.) The sample shows the three FSK Header Burst with one second pause between each one, at least one second pause, relayed audio content, at least one second pause, and the three ‘NNNN’ FSK bursts (EOM). [PREAMBLE] This is a consecutive string of bits (sixteen bytes of AB hexadecimal [8 bit byte 10101011]) sent to clear the system, set AGC and set asynchronous decoder clocking cycles. The preamble must be transmitted before each header and End of Message code. ZCZC—This is the identifier, sent as ASCII characters ZCZC to indicate the start of ASCII code. ORG—This is the Originator code and indicates who originally initiated the activation of the EAS. These codes are specified in paragraph (d) of this section. EEE—This is the Event code and indicates the nature of the EAS activation. The codes are specified in paragraph (e) of this section. The Event codes must be compatible with the codes used by the NWS Weather Radio Specific Area Message Encoder (WRSAME). PSSCCC—This is the Location code and indicates the geographic area affected by the EAS alert. There may be 31 Location codes in an EAS alert. The Location code uses the codes described in the American National Standards Institute (ANSI) standard, ANSI INCITS 31-2009 (“Information technology—Codes for the Identification of Counties and Equivalent Areas of the United States, Puerto Rico, and the Insular Areas”). Each state is assigned an SS number as specified in paragraph (f) of this section. Each county and some cities are assigned a CCC number. A CCC number of 000 refers to an entire State or Territory. P defines county subdivisions as follows: 0 = all or an unspecified portion of a county, 1 = Northwest, 2 = North, 3 = Northeast, 4 = West, 5 = Central, 6 = East, 7 = Southwest, 8 = South, 9 = Southeast. Other numbers may be designated later for special applications. The use of county subdivisions will probably be rare and generally for oddly shaped or unusually large counties. Any subdivisions must be defined and agreed to by the local officials prior to use. +TTTT—This indicates the valid time period of a message in 15 minute segments up to one hour and then in 30 minute segments bey…
