Section I: EAS-1/CG Description
EAS-1/CG Encoder Specifications
Access Control: Access to the encoder to generate an alert is protected against
unauthorized personnel generating false alerts by requiring a four-digit access code which
must be entered from the front panel keypad or optional telephone interface. The four-digit
code is not required if the encoder is being programmed through the DB9 S232 PC port or
when a valid incoming alert is being manually forwarded.
Audio Storage: The encoder has the capability of inserting an up to two-minute audio portion
of the alert message by using a microphone or playing back up to two minutes of audio stored
in the internal digital audio storage unit, as well as recording and replaying another up to one-
minute audio message that is normally used for a "tune-to" message. With the inclusion of the
optional telephone interface, the audio portion of the two-minute alert message can be stored
in the encoder from a remote location using a telephone or similar device with a DTMF
telephone keypad. The keypad can be used to play back the stored audio messages for
editing prior to forwarding a complete, full-blown EAS civil emergency message. The DB9
S232 PC port can be used to compose a data message using a 1200 baud rate. Audio may
be recorded either through input 6, which also will accept an amplified studio microphone, or
through the front-panel speaker.
Audio Outputs: The encoder has an adjustable balanced audio output on the rear of the unit,
in one of the terminal plugs, which is 600 ohms @ +8 dbm max. The DB9 PC port is a two-
way data port which can be used as a data output port ( S 232, 1200 baud). The front panel
keypad is used to adjust the internal digital pots which set the output level of each of the four
frequencies used to generate the FSK header and dual-tone attention signal.
Header Infor ation: When the encoder originates a message, the date, hour and minute
that are derived from the internal clock are encoded in the burst of FSK as well as the
identification of the originating entity.
Other Features: The programming data and stored audio messages are non-volatile and
unaffected by power interruption. The front-panel 4-line, 40-character display lets the operator
know what the encoder and decoder are doing at all times. The display reports sending or
receiving FSK, attention signal, voice message and EOM. The front-panel speaker
simultaneously presents the same audio and if the unit is installed in a room where radio
traffic is generated, a microphone switch can be wired in through the rear terminal block to
mute the speaker on the EAS while the microphone is being used in the radio room.

Gor an-Redlich EAS-1/CG Decoder Specifications
Audio Inputs: The EAS-1/CG decoder section provides six audio inputs which greatly
exceeds the FCC specification of two audio inputs from EAS monitoring assignments. It also
has a DB9 S232 data input port which operates at 1200 baud.
Message Handling: The unit compares the three bursts of FSK and must have the same
data at each position in the header in two out of the three bursts of FSK to have a valid
header. If this condition is met, the unit then checks to see if the incoming message is a
duplicate of one already received, or if the message was originated by the receiving unit.
Duplicate messages are printed out but cannot be forwarded. If neither of these two
conditions are met, it next checks to see if the incoming message has expired. If the incoming
message is still within its valid time period, the unit checks to see if the event is one of the
required or preselected event codes. If this condition is satisfied, the decoder next checks to
see if there is one of the programmed counties in the incoming header. If all of these
conditions are met, the audio (up to two minutes in length) will be stored and this message
can be forwarded.
Header Storage: The EAS-1/CG can currently store twenty preselected event and originator
coded combinations, exceeding the FCC's required ten, in addition to the four mandatory
code combinations of tests and national activations. Firmware has been completed and is
being tested to expand the preselected table and to permit additional event codes to the be
entered (in the current test version, all 32 available header codes may be programmed and
stored). The header codes of the last ten received valid messages are stored for comparison
with the incoming valid header codes of later messages.
Inco ing Messages: Valid EAS header codes that are received are converted to a text
message and displayed on the 4-line, 40-character, LED backlit display. The audio message
portion of an alert is heard on the front panel speaker. The EAS-1/CG also monitors each of
the audio inputs and presents a visual indication of whether or not the audio is present on
each channel. Program data is preserved in case of loss of power.
Other Features: The decoder has a DB9 S232 1200-Baud data port where received
messages are available for logging. The front panel keypad can be used to monitor each
decoder audio input using a built-in front-panel speaker. Decoder programming is protected
from unauthorized adjustments by the requirement that four-digit code be entered on the front
panel keypad.
The decoder will automatically reset after two minutes if the originator of the incoming
message fails to send the EOM. Only the EAN event code can override this feature. When the
EAN code is received, it will automatically override any other incoming code.

Section II: Setting up the EAS-1/EAS-1CG
1. When installing the unit in the rack, be sure to ground it well. We recommend
grounding it to the rack from one of the rear grounding screws, and then grounding the
rack.
2. We strongly recommend placing the EAS-1/CG on an uninterruptible power supply
(UPS). The printer and the receivers used to monitor the National Weather Service
and/or broadcast stations should also be plugged into this.
3. When installing the printer, be sure to use an IEEE shielded parallel printer cable. Also,
we strongly recommend finding a used dot-matrix printer with a normal-width capacity.
In our experience, these work better than laser or inkjet printers.
4. Input audio should always be connected to the lower-numbered input channels
(terminals 1-12). However, if there is an input from the National Weather Service, it
should be connected to input channel 3 (terminals 5-6). Studio microphones should be
routed to input 6 (terminals 11-12), and must go through an amplifier.
5. Once the audio inputs are connected, it's essential to set the input levels. Instructions
for doing this are to be found in Section VIII, item 3.
6. Once the program audio lines are looped through the unit, it's essential to set the
modulation, using the outgoing program line. The 853 and 960 tones should be set at
forty percent, while the 1560 and 2083 tones should be set at eighty percent.
Instructions for doing this are to be found in Section VIII, item 2.
7. A sign board in the "on-air" studio is a good idea if the EAS-II equipment is installed in
another room. Warning messages will be scrolled in ED, watches in YELLOW, and
required tests in G EEN. If you are using a sign board, Utility Menu option 11 should
say "TOGGLE SIGN OFF " and if you are not using a sign board, it should say
"TOGGLE SIGN ON." Pressing changes this from one to the other.
8. When the unit operates in any mode other than MANUAL, incoming header codes
targeted for one of the counties in the listening area trigger two sets of relay contacts.
These close for one second upon completion of the three bursts of FSK EOM
(terminals 19 & 20 and 21 & 22). This contact closure can be used to turn on a bell or
light, or signal remote control or automation equipment. Some locations operate in
manual twenty-four hours and do not interface with automation, but would like to have
a contact closure under the above circumstances to call attention to the incoming
message. If Utility Menu option 12 reads "TOGGLE ALERT OFF," the contacts will
close in manual, also.
9. If the station is an LP1 or and LP2, the required monthly test that you originate should
have a valid time period of one hour. All other stations that originate an MT should
use a valid time period of 15 minutes.
10.Be sure to go through the other sections of this manual, especially Section VIII: Using
the EAS-1/CG Utility Menu. We strongly recommend going through this section, step
by step, to better familiarize yourself with the system. If you need to change any
programming for your location, then be sure to read Section X: Station Setup.
Section III: Setting up the EAS-1/EAS-1CG
NOTE: The DOS EAS Setup software has been replaced by a new Windows compatible
setup program. Check the Gorman edlich website for the instruction manual for the new
software version (PDF reader required).
