EASy-PLUS® User Manual6 – TRILITHICRev 1.02SECTION 1GENERAL INFORMATION1.1 INTRODUCTIONThe EASy-PLUS® encoder/decoder is a third generation product from Trilithic, Inc. The encoder/decoder is a fully self-contained system, which includes a NTSC video character generator output, multiple balanced audio outputs, audio andvideo switching, 100 message queue, speaker and microphone, two internal AM/FM/NOAA radios and four program-mable contact closures used for such things as OM-1000 digital switching.The EASy-PLUS® E.A.S. Encoder/Decoder is a two-U rack mounted control center capable of performing manual or auto-mated EAS messaging for cable Headends and Hub sites, in accordance with CFR 47 part 11 FCC regulations, and theEAS Cable Handbook.The EASy-PLUS® receives E.A.S. messages from up to six audio sources (internal or external), decodes the message, andoperates Cable System equipment to replay the message for subscribers. In addition, messages can be originated by theuser via local or remote control of the EASy-PLUS®. The E.A.S. audio sources for the EASy-PLUS® include internal AM/FM/NOAA radios and external audio inputs that can be connected to any known E.A.S. audio source. E.A.S. audio isdecoded by the internal AFSK circuitry, sorted, and then interpreted to determine the type of emergency or test. Thelocations codes for which the emergency applies, and other information supplied in the E.A.S. header are also decoded. Ifa voice message is contained in the E.A.S. message, it is recorded for playback to subscribers. E.A.S. messages thenpass through a series of tests to determine if the message matches predefined, user configurable filters and parameters foryour location. E.A.S. activation of the cable system then automatically occurs. To play an E.A.S. message to your subscrib-ers, the EASy-PLUS® activates TTL drivers and Contact Closures, as well as sending commands via RS-485 and HighData Rate AFSK. The EASy-PLUS® also supplies pertinent video and re-encodes and plays the E.A.S. FSK header andrecorded audio. The TTL drivers, Contact Closures, and RS-485 commands activate your interface equipment (i.e. I.F.switching, comb generator, baseband character generators) throughout the headend to provide the emergency audio andvideo to all channels of the cable system. In addition to the E.A.S. messaging capabilities, the EASy-PLUS® logs allreceived and transmitted messages to a printer, the LCD display, and it’s internal log storage area.The EASy-PLUS® has an optional dial-in telephone interface and a unique remote feature using EASy-NET® optionalsoftware for remote control of the entire system. Using the EASy-NET® software, the operator can generate any eventcode and header by simply clicking on the list of events. Prerecorded, or live audio can also be added to the event.FLASH-BIOS is used to update the EASy-PLUS® nonvolatile memory, programming, and FCC event codes list.The EASy-PLUS® encoder/decoder has the ability to parse FIPS codes out to individual counties or areas in conjunctionwith the appropriate wiring architecture of the cable headend. This keeps the interruptions to a minimum for customersnot affected by the alerted area.Trilithic’s unique AFSK transmitter card comes standard in the system. The AFSK signal alerts Trilithic’s downstreamVirtual Controllers to perform channel insertions at remote hubs, OTNs, and headends for channels not originating at themaster headend.The EASy-PLUS® encoder/decoder can handle cross-county applications as well as cross-state-line scenarios. Multiplestates and counties can easily be added with a click-of-the-mouse.1.2 UNPACKING AND INSPECTIONWhen your system arrives, immediately inspect its shipping container and contents for visible damage. Keep all packingmaterials until equipment performance has been confirmed. If any of the equipment is damaged or fails to operateproperly due to transportation damage, file an immediate claim with the transportation company or, if insured separately,with the insurance company.The EASy-PLUS® encoder/decoder may, or may not, arrive in a single shipping container.

EASy-PLUS® User Manual10 – TRILITHICRev 1.02SECTION 2UNDERSTANDING THE EASy-PLUS® SYSTEM2.1 INTRODUCTIONThis section includes an overview and description of the EASy-PLUS® equipment including front and rear panel controls,connectors and displays. The EASy-PLUS® encoder/decoder is the device which, when radio station signals aresupplied to its internal radios, decodes Emergency Alert System header information when monitoring your (local primary)LP-1 and LP-2 stations, and optionally, your National Weather Service radio signals (on NOAA frequencies 162.400 MHz(WX2), 162.425 (WX4), 162.450 (WX5), 162.475 (WX3), 162.500 (WX6), 162.525 (WX7), 162.550 (WX1).Your LP-1 (local primary one) and your LP-2 (local primary two) radios are usually an FM and AM radio station, respec-tively. These radio stations are assigned in your state emergency plans, usually available on the home WEB site for yourstate. Your state plan should detail how your entire state emergency alerting system functions, including your assigned(SP) state primary frequencies and transmitter locations. Your LP-1 and LP-2 broadcasters typically have the obligationto pass through to your encoder/decoder the EAN (that’s the Emergency Action Notification-the presidential message)and the RMT (the Required Monthly Test). You will also receive RWT (Required Weekly Tests), which you may, or maynot, be required to pass on to your cable system headend. You are required to perform your own locally generated RWT,which can be done from the front keypad, remotely via a telephone, or by using the random RWT generator built intoyour EASy-PLUS® system.Your EASy-PLUS® encoder/decoder is the first piece of equipment to receive the alert from your monitoring stations. Itwill decode the signal, format the message into an NTSC video signal (standard analog format) and present this video toits output port (CG VIDEO OUT). Depending on whether you’ve looped your “designated E.A.S. channel” video throughthe CG VIDEO IN, your E.A.S. will either crawl over incoming video, or crawl over an internally generated full-screenE.A.S. page.The E.A.S. alert audio associated with the message is also available at the rear connector and is distributed to eitheryour I.F. switching interface or your comb generator, just as the video output is distributed to these same interfaces.For remote hub site channel insertions downstream, your EASy-PLUS® has a built-in AFSK in-band data generator forsignally Trilithic’s remote headend/hub site Virtual Controller. The V.C. is used for multiple applications at remote hubsites for performing channel insertions, remote OM-1000 control for force-tuning Motorola settops during an E.A.S. alertas well as many other off-site applications.The FCC requires logging of all incoming E.A.S. events and tests. This is accomplished by applying a customer-supplied parallel printer (non-Windows driver based) to the DB-25 parallel printer port at the rear of the EASy-PLUS®system.Visit WWW.TRILITHIC.COM and click on EAS DIVISION to view or download manuals on all of Trilithic’s E.A.S.products.2.2 FRONT PANELThe EASy-PLUS® front panel contains four items.Perforated holes for the internal microphone.Perforated area for the internal speaker.LCD display16 button keypadThe keypad is used for rudimentary setup at the cable headend and for initiating the Required Weekly Test. Most setupfeatures are programmed using the SETUP program provided with each EASy-PLUS® encoder/decoder.ENCODERInitiating E.A.S. events (other than the RMT and RWT) is accomplished using the SETUP software. Activation of eventswill be covered in the software setup section of this manual.DECODERThe decoder is an automated mechanism used to decode incoming E.A.S. messages via the baseband radio inputsignals to the microprocessor.2.3 BACK PANELRS-232 COM1 Used for uploading setup data from PC or Laptop.COM2 Future Use.PARALLEL PORT: Used for connecting a standard (EPSON emulation) parallel printer for FCC mandatory logging of allincoming E.A.S. events and tests.CG VIDEO: IN: Connect “designated E.A.S. channel” video, (your tune-to channel), to CG VIDEO IN, if and only
EASy-PLUS® User Manual – 11TRILITHIC Rev 1.02if, you plan to use a video distribution amplifier at the CG VIDEO OUT to distribute the video back toyour tune-to modulator as well as to your comb generator. NOTE: This is done only if you plan touse a “tune-to” video and audio message supplied to your comb generator prior to running the alerton your “designated E.A.S. channel”. This will be explained further in the applications section of thismanual.OUT: Connect CG VIDEO OUT to the input of your I.F. source modulator or to your comb generator.If you are using an external video D/A, connect to input of D/A and then connect one output to yourcomb generator and one output to your “designated E.A.S. channel” video input.AUDIO EXPANSION 1:Ch 1: AM or FM or NOAA radio antenna input.Ch 2: AM or FM or NOAA radio antenna input.AUDIO EXPANSION 2:Ch 3: AM or FM or NOAA radio antenna input.Ch 4: AM or FM or NOAA radio antenna input.RS-485: For use with Trilithic external character generators, remote Virtual Controllers.2.4 TERMINAL CONNECTOR:TTL OUTPUTS: The individual programmable outputs which switch between TTL levels of 0 and 5 vdc.

EASy-PLUS® User Manual – 21TRILITHIC Rev 1.02SECTION 6EASy-PLUS® Encoder/Decoder Installation and Wiring6.1 INTRODUCTIONThe EASy-PLUS® receives E.A.S. messages from up to six audio sources (internal or external), decodes the message, andoperates Cable System equipment to replay the message for subscribers. In addition, messages can be originated by theuser via local or remote control of the EASy-PLUS®. The E.A.S. audio sources for the EASy-PLUS® include internal AM/FM/NOAA radios and external audio inputs that can be connected to any known E.A.S. audio source. E.A.S. audio is decodedby the internal AFSK circuitry, sorted, and then interpreted to determine the type of emergency or test. The locations codesfor which the emergency applies, and other information supplied in the E.A.S. header are also decoded. If a voice messageis contained in the E.A.S. message, it is recorded for playback to subscribers. E.A.S. messages then pass through a seriesof tests to determine if the message matches predefined, user configurable filters and parameters for your location. E.A.S.activation of the cable system then automatically occurs. To play an E.A.S. message to your subscribers, the EASy-PLUS®activates TTL drivers and Contact Closures, as well as sending commands via RS-485 and High Data Rate AFSK. TheEASy-PLUS® also supplies pertinent video and re-encodes and plays the E.A.S. FSK header and recorded audio. The TTLdrivers, Contact Closures, and RS-485 commands activate your interface equipment (i.e. I.F. switching, comb generator,baseband character generators) throughout the headend to provide the emergency audio and video to all channels of thecable system. In addition to the E.A.S. messaging capabilities, the EASy-PLUS® logs all received and transmitted mes-sages to a printer, the LCD display, and it’s internal log storage area.7.2 INSTALLATION AND WIRING OF THE EASY-PLUS® ENCODER/DECODERTypical installation of the encoder/decoder requires the operator to attach radio antenna inputs at the Audio Expansion 1coaxial input connectors, attach AUDIO and CG VIDEO Outputs to either an I.F. source modulator or audio input to a combgenerator, and attach either TTL control line output to I.F. switching devices or a contact-closure output to the comb genera-tor. Optional control of the Motorola OM-1000 QPSK modulator is accomplished by using a secondary contact-closureattached to the red and black terminals at the rear of the OM-1000.7.3 PINOUT DESIGNATIONS AT THE REAR PANEL OF THE EAS-yPLUS® ENCODER/DECODER.asf

EASy-PLUS® User Manual – 23TRILITHIC Rev 1.02SECTION 7I.F. (Composite I.F., Aux. I.F., Single I.F.) INTERFACE and INSTALLATION7.1 INTRODUCTION Single I.F. ReplacementComposite I.F. (both visual and aural intermediate carriers on the same coaxial cable) replacement is a technique whichis used to change the program content on a channel without altering the RF output carrier frequency or amplitude. Withthis technique you will need to install an I.F. switch in the composite I.F. loop-through on the rear of the modulator orprocessor housing (i.e. the channel’s rack mount assembly). Generally, modulators have this I.F. loop on the back of thehousing. In some cases, you may be able to install the loop into the housing to implement this type of switching. For theE.A.S. application, the alternate I.F. signal will be taken from an independent distribution system which will be explainedas you move through this manual.Single (Composite) I.F. Switch Installation (SW-1)The first step when assembling the E.A.S. system is to install an SW-1 or SW-4 switch on the rear of each modulator orprocessor. The SW-1 is a three terminal device used to substitute the current I.F. source with an alternative I.F. source.The SW-4 switch is a two terminal device with a terminal strip localize as a contact-closure for such chassis as the S-AContinuum modulators and processors.For each SW-1 installed, you will need two (2) 75 Ohm cables of equal length about three (3) to six (6) inches in length.The next step will cause a brief interruption of the channel involved while the I.F switch is being connected, but the signalwill return once the switch is installed.Connect the 75 Ohm cable from the I.F. OUT of the modulator or processor to the I.F. IN of the SW-1 switch. Connectthe I.F. OUT of the SW-1 switch to the I.F. IN of the same modulator or processor. See the following diagram.

Channel” at I.F.You will assign one channel on the cable system as the “Designated E.A.S. Channel”. This is the channel on which allE.A.S. alerts and messages received via your Local Primary monitoring stations (i.e.: AM, FM, or NOAA) will bedisplayed. Depending on installation techniques used, these messages and alerts will appear in the form of a gen-lockedcrawl message over either the existing video or over a full page blue background. Selecting a low priority channel (onewhich is not trapped or scrambled as it enters every home on the system) as the “Designated E.A.S. Channel” isoptimum. Generally, a community access channel, government channel, or character generator channel in the VHFtelevision band (i.e.: ch. 2-13) is ideal to use for the “Designated E.A.S. Channel”.NOTE: IN ALMOST ALL INSTANCES A MODULATOR WITH A COMPOSITE I.F. LOOP WILL BE USED FOR THE“DESIGNATED EAS CHANNEL”. THERE ARE EXCEPTIONS, SUCH AS BASEBAND OR CHARACTERGENERATOR EAS SYSTEMS OR COMBINATIONS OF BASEBAND AND I.F. SYSTEMS. THESE EXCEP-TIONS WILL BECOME APPARENT IN EACH INTERFACE SECTION OF THIS MANUAL.7.3 LS-16P Lossless Splitter Placement and ConnectionThe LS-16P is a precision I.F. distribution amplifier (D/A) which has a 20dB continuously variable precision attenuator forI.F. alignment on each of its 16 output connections. The LS-16P is also used to insert a DC drive voltage on the outputdrop cable’s center conductor for activating each SW-1 or SW-4 switch, as well as other LS-16P input connections whenthe EAS system is activated.For most applications, multiple LS-16P(s) will be needed. In all installations, the first LS-16P, which receives its input
EASy-PLUS® User Manual – 25TRILITHIC Rev 1.02from the I.F. source modulator, should be labeled by the customer as the “Primary LS-16P”.Any other Primary LS-16P output port may be used to drive Secondary LS-16P(s) input ports or SW-1 and SW-4switches.For example, in a typical headend of 46 channels you will need three (3) LS-16P(s). One LS-16P will serve as thePrimary and the two (2) remaining LS-16P(s) will serve as Secondaries. Total channel capacity will be twelve (14) portsfrom the Primary LS-16P, with the remaining two (2) ports of the Primary feeding two (2) Secondary LS-16P(s). Two (2)times sixteen (16), or thirty (32) ports from the Secondary LS-16P(s) added to the fourteen (14) ports leftover from thePrimary LS-16P totals 46 ports.As shown in the following diagram, one (1) LS-16P will serve up to sixteen (16) remotely located SW-1 and/or SW-4equipped modulators and processors and/or Secondary LS-16P(s). When installing the LS-16P, place in bays or rackswhere their distribution coverage will be maximized. See the following diagrams.Typical LS-16P Placement and Connection.Bundled drop cable feeding I.F. switchesLS -16P
EASy-PLUS® User Manual26 – TRILITHICRev 1.02The composite I.F. distribution system is now installed.7.4 Auxiliary I.F. Switch Installation (SW-4)The SW-4 switch is used to locally activate a contact closure on the rear of a modulator or processor enabling theinternal I.F. switch built into the chassis. The E.A.S. I.F. signal and DC current are fed to the input port of the SW-4switch from the LS-16P. The signal passes through the switch to the Aux. I.F. Input port on the rear of the modulator orprocessor. The DC current is blocked at the input to the SW-4 and converted to a normally open (N/O and N/C) contactclosure. The N/O terminal of the SW-4 should be attached to the rear of the modulator on the appropriate screw terminalto cause the internal I.F. switch to activate when the LS-16P distribution system sends its signal to the SW-4. The groundterminal on the SW-4 should also be attached to an appropriate grounding point on the modulator or processor.Rear ViewFront ViewLS-16P15 13 11 9 7 5 3 1I.F.

EASy-PLUS® User Manual – 27TRILITHIC Rev 1.027.5 Single (Composite) I.F. Source Modulator Installation (IFS-3)The I.F. modulator receives its video signal from the CG VIDEO OUT at the rear of the EASy-PLUS® and audio from theterminal strip and modulates these signals onto I.F. subcarriers. Once the IFS-3 source modulator is mounted, connectthe RF OUT port to the I.F. IN port on the Primary LS-16P.7.6 Precision I.F. Level Alignment of the LS-16P Lossless SplitterThe LS-16P was designed for precision I.F. output level adjustment. In most instances, different modulators or proces-sors require different I.F. input levels to maintain proper RF output levels due to the absence of an AGC at the I.F. stage.It is imperative that the headend maintain the same R.F. output level on each channel during an entire E.A.S. sequenceof events. When alternate I.F. levels match those I.F. levels which are currently present at the rear of the modulator orprocessor, system wide stability of the trunk amps, pilot carriers, slopes, R.F. levels and scrambling systems will bemaintained.DC power is delivered through the coaxial cable’s center conductor to enable the Secondary LS-16P(s), the SW-1(s),and the SW-4(s) switches.CAUTION: DO NOT INSTALL FIXED OR VARIABLE ATTENUATOR PADS IN THE INPUT OR OUTPUT CABLES OFANY LS-16P LOSSLESS SPLITTER. ELECTRICAL SHORTING OF THESE DEVICES MAY OCCUR.The I.F. alignment procedure consists of setting the output level of the I.F. source modulator and then setting the outputlevels on the Primary and Secondary LS-16P(s) for proper I.F. levels at the rear of the modulators and processors. TheMaster Gain on all LS-16P(s) is factory set to unity gain. This adjustment should not need to be reset. Each 20dBpotentiometer on the front panel of the LS-16P is factory set to 0 dB loss (i.e.: 42 dBmV output on each port of the LS-16P if the IFS-3 is set to 42 dBmV output.)The test point on the front panel of the LS-16P(s) is to check for signal presence ONLY. No test alignment measure-ments should be made at this test point.7.7 Procedure for precision I.F. Alignment:1. Set the output level of the I.F. source modulator to maximum and then pad its output down to 2 dBmV higherthan the highest I.F. level on your modulators/processors (typically 32-42 dBmV). Set the audio carrier level13-17 dBmV down from the video carrier.2. Turn all J1 - J16 dip switches on the front panel of the Primary LS-16P to OFF (disabled), except for those dipswitches which control the feeds of the Secondary LS-16P(s) INPUTS. These dip switches will remain ON(enabled) at all times.3. Enable the I.F. alignment mode in the menu system of the EASy-PLUS® encoder/decoder.4. Using a spectrum analyzer or field strength meter connected to the trunk line test point, identify the channelunder alignment.5. If applicable, be sure to disable any I.F. AGC switches on all modulators in the headend under I.F. alignment.6. Looking at the channel under alignment on the spectrum analyzer or field strength meter, note the output level.7. Turn the dip switch ON (enable) for the channel under setup, ONLY. This will enable the SW-1 or SW-4 switchat the rear of the modulator or processor under setup. You should now see the “I.F. Alignment Screen” appearon the television on the channel under test channel.8. Using the respective potentiometer J1 - J16 on the front of the LS-16P for the channel under alignment, turnthe potentiometer counterclockwise until the exact R.F. output level is achieved on the spectrum analyzer orfield strength meter.9. Turn the appropriate dip switch back OFF (disable) on the LS-16P.10. Proceed to the next channel and repeat steps 4 through 10 until all channels are aligned.11. Turn the I.F. AGC(s) ON for all modulators.12. At the keypad of the EASy-PLUS unit, take the menu system out of I.F. alignment.13. Turn all dip switches ON (enable).CAUTION: The EAS system will not trigger in the automatic mode for an EAS alert while the system is in the “I.F.Alignment” mode.You have now completed the composite precision I.F. alignment procedure.
