1.7 TECHNICAL SUPPORT Technical support is handled first, through the supplier of your equipment. If your supplier does not meet your service or repair needs, you may contact the manufacturer directly. Before any Trilithic Emergency Alert System equipment is returned for repair, the supplier, and/or Trilithic will issue an RMA# (Return Material Authorization). NO EQUIPMENT WILL BE ACCEPTED THAT DOES NOT HAVE THIS RMA NUMBER PROMINENTLY DISPLAYED ON THE OUTSIDE SHIPPING CARTON AND ON THE LABEL.
SECTION 2 UNDERSTANDING THE EASy-PLUS® SYSTEM 2.1 INTRODUCTION This section includes an overview and description of the EASy-PLUS® equipment including front and rear panel controls, connectors and displays.
if, you plan to use a video distribution amplifier at the CG VIDEO OUT to distribute the video back to your tune-to modulator as well as to your comb generator. NOTE: This is done only if you plan to use a “tune-to” video and audio message supplied to your comb generator prior to running the alert on your “designated E.A.S. channel”. This will be explained further in the applications section of this manual. OUT: Connect CG VIDEO OUT to the input of your I.F. source modulator or to your comb generator.
SECTION 3 PRE-INSTALLATION SYSTEM CHECK 3.1 INITIAL POWER APPLICATION When 120 VAC power is applied to encoder/decoder, the system will perform an internal self-check. If the system suffers from any internal failures, an error message or code will most likely be displayed on the LCD readout. 3.2 SELF-TESTING THE ENCODER/DECODER Press the button labeled with a ? Scroll down to Required Weekly Test (RWT) and initiate.
SECTION 4 BASIC PROGRAMMING OF THE EASy-PLUS ® ENCODER/DECODER 4.1 INTRODUCTION You may skip the BASIC PROGRAMMING in Section 4 and proceed directly to Section 5 to program the entire EASy-PLUS ® encoder/decoder’s nonvolatile memory and storage. The following procedure will require a PC or Laptop computer running Microsoft Windows 95 or later. The encoder/decoder does not need its setup software to be programmed.
SECTION 5 ADVANCED PROGRAMMING OF THE EASy-PLUS® ENCODER/DECODER 5.1 INTRODUCTION A null-modem serial cable supplied with the EASy-PLUS unit should be connected between a serial port a the PC or Laptop and COM1 at the rear of the EASy-PLUS unit. NOTE: Use only the serial cable supplied with the system. The advance setup software has been included in the shipping carton with the EASy-PLUS® encoder/decoder. It will be either a diskette or a CD.
ENTERING SYSTEM INFORMATION From the SYSTEM tab, make the appropriate selections for the following: SYSTEM NAME Enter your cable system name. CALL LETTERS Enter up to an eight character abbreviation for your cable system name in the CALL LETTERS box. ORIGINATOR Select EAS Broadcast Station or Cable System TIME ZONE Select the time zone which your headend resides in. ENABLE DAYLIGHT SAVINGS Select if your system headend is in a county/parish which adheres to Daylight Savings Time in April.
SELECTING COUNTIES COUNTIES tab Select the state your headend is in by pulling down the Select a State menu and then left-clicking on the appropriate states. You may select more than one state. Scrolling down the list of counties, first select your county that the E.A.S. headend system is located. Click on the County of Licence button. Then select the rest of the counties with which you feed cable or fiber to or which you have subscribers currently residing.
SELECTING EVENTS EVENTS tab On the EVENTS tab you will check each event desired, and then Enable Selected Event. To configure for each, click on the Configuration tab. Select EAS Channel, Tune To, or Full Screen for the display type of each event. If remote hub site channel insertions take place, enable the AFSK option by clicking on its button. Select Valid Originators for the Event enables which type of incoming radio transmission is valid for each event.
SELECTING CONTACT-CLOSURES EVENTS Contact Closures Typical headend components which need a contact-closure to operate are a comb generator or Motorola’s OM1000 data modulator. During the enabling and configuration of each event, there will normally be a contact-closure paired with the event. The relay contacts are found at the rear of the EASy-PLUS ® system. Enable the necessary number of contact-closures at the rear terminal strip of the EASy-PLUS ® unit by clicking on the Enable buttons.
SETTING AUDIO INPUTS AUDIO CFG Enable the Radio Receiver Board and then select FM or AM frequency band. Set the frequencies needed in your local area. Your local LP-1 and LP-2 monitoring stations can be found in your state’s SECC E.A.S. plan or contact a local radio or television broadcaster. If you cannot find a copy of the plan try contacting the FCC or go on-line to WWW.FCC.ORG and search their E.A.S. database. When selections are complete, go back to the System tab and click on Upload Configuration.

SECTION 7 I.F. (Composite I.F., Aux. I.F., Single I.F.) INTERFACE and INSTALLATION 7.1 INTRODUCTION Single I.F. Replacement Composite I.F. (both visual and aural intermediate carriers on the same coaxial cable) replacement is a technique which is used to change the program content on a channel without altering the RF output carrier frequency or amplitude. With this technique you will need to install an I.F. switch in the composite I.F. loop-through on the rear of the modulator or processor housing (i.e.
connect the EAS IN at the SW-1 switch later in this procedure. Repeat this procedure on all modulators and processors that have a composite I.F. loop-through on the rear of their housing. 7.2 Selecting a “Designated E.A.S. 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 all E.A.S. alerts and messages received via your Local Primary monitoring stations (i.e.: AM, FM, or NOAA) will be displayed.
from 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-4 switches. For example, in a typical headend of 46 channels you will need three (3) LS-16P(s). One LS-16P will serve as the Primary and the two (2) remaining LS-16P(s) will serve as Secondaries.

7.5 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 the terminal strip and modulates these signals onto I.F. subcarriers. Once the IFS-3 source modulator is mounted, connect the 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 Splitter The LS-16P was designed for precision I.F. output level adjustment.
