Features

  • 5 bi-directional RS232 inputs/outputs for computer, modem, remote sign board, character generator

  • 6 Audio inputs on standard models. All audio inputs and outputs are transformer isolated from encoder-decoder board.

  • Automatic interruption of stereo program lines when pre-selected header code is received for insertion of alert message on transmitter. No external relay panel is required.

  • 2 minutes of digital audio storage (5 kHz)

  • 5 programmable relays to supply contact closures to handshake with automation equipment or signal other equipment.

  • 25 pin parallel printer port for external printer to keep E.A.S. log.
  • Alert is displayed on a 4 line 40 character back lighted LCD display for rapid interpretation of alert message. Alert message can also be scrolled on a remote sign board, a computer screen or with a character generator on a video monitor.

  • 20 key keypad to set input level.

  • Can have password code that will be known only by those who will be adjusting the equipment.

  • Automatic reset of decoder after 2 minutes.

  • The stored audio message can be routed to the speaker for review so that the urgency of the message can be gauged.

  • Will operate over audio input levels from 0.14 V to 2 V R.M.S.

  • Diagnostic information can be printed out on a printer if unit is malfunctioning and can be faxed to us for analysis.

  • Quality 2 1/2 inch 8 ohm front panel QUAM speakers for clear audio.

  • Non-volatile memory and non-volatile voice storage.

  • 4 layer board with all signal traces on top and bottom and all IC's mounted in sockets for ease of repair.

  • Unit has a CMOS EPROM 32 PIN 1MB for future changes.

  • Units are programmed for your location at no charge.

  • Can be easilyupgraded to an EAS encoder-decoder unit to meet your stations expanding requirements.

  • Compatible with both RS232 and FSK modes of the CAP-DEC 1 CAP-to-EAS decoder.

  • Easily configurable using the Gorman-Redlich Setup Software (Windows XP/Vista/7 and DOS compatible)

Rear Panel Terminal Description

Term. Label Description
1-12 Audio In-Monitor inputs 1-6 Six pairs of audio inputs are each coupled to the decoder by 600 ohm to 600 ohm isolation transformers. These six audio sources are scanned for EAS alert messages.
13-14 Audio Out - 600 ohm select Balanced 600 ohm continuous audio output from an operator selected monitor input.  Any channel #1 - #6.
15-16 Audio Out - 8 ohm select. Balanced 8 ohm continuous audio output from an operator selected monitor input. Any channel #1 - #6.
17-18 Audio Out - 600 ohm alert Balanced 600 ohm audio output from the channel carrying the alert message.
This output is gated on when the alert takes place
19-22 Control Out - Alert Two contact closure outputs can be used to signal remote control equipment, automation equipment, or to activate a remote bell or lamp.
23-24 Console Muting These terminals allow console muting of the panel speaker when the unit is installed in an on/air room.
25-32 Audio In/Out Program Lines A/B Eight terminals for balanced 600 ohm stereo program audio lines. Via these inputs and outputs, the encoder interrupts the program audio to insert the alert message.
33-34 Control Out - Send Alert Contact closure which can complete the circuit for an external relay coil for a coaxial relay during the time the encoder is sending an alert signal. This will allow a low impedance coaxial alert feed directly into a transmitter exciter circuit, thus bypassing all audio processing or energizing external relays to put the alert on additional transmitters.
35-36 Control Out - EAS - Complete Contact closure output to signal automation equipment that the EAS interruption is completed.
37-38 Control In - Delete Audio Contact closure input for deleting the 853/960 attention signal and the audio message portion of a received alert message. The encoder will send only the FSK (frequency shift keying) header and EOM (end of message) portions. The contact closure would be supplied by remote switch or remote control equipment contacts.
39-40 Control In - Send Alert Contact closure input to tell encoder to send a stored alert message now.
41-42 Control In - Local Contact closure input to switch the encoder from automatic to manual control.
43-44 Control In - EOM Contact closure input to remotely send EOM (end of message). FSK code.
45-46 Control In - RWT Contact closure input to remotely send RWT (required weekly test). FSK header code and FSK EOM code.
47-48 Control In - RMT Contact closure input to remotely send RMT (required monthly test). FSK header code and dual tones.
49-50 Data In/Out - RS485 Serial data option for future remote control equipment.
51-52 Spare terminals for future use.
