Introduction:

The DASDEC-III Emergency Alert System (EAS) Analog and Digital CAP/ Encoder/Decoder platforms are relatively easy to install and set up. This manual covers the installation and hardware connections of the DASDEC-III.

Hardware:

The DASDEC-III is a 2U rack-mounted EAS device that utilizes standard computer technology in a dedicated chassis with broadcast quality connectors. The PC motherboard uses industry-standard connectors for USB, PS/2, serial, VGA, HDMI, networking, and audio. In addition to the standard motherboard connections, the platforms feature broadcast-quality video, audio, antenna, contact closure, and power connectors. All external connectors are located in the rear of the unit. An LCD with a backlit tactile keypad, status/alert LEDs, and an internal speaker are located on the front of each unit.

Front Panel:

The Expansion Slots are used for optional additional Network Interfaces and additional EAS Audio input hardware. Expansion hardware is only available with the DAS3-EX or the DAS3-GX.

Installation

The DASDEC-III frame mounts in an EIA-compliant equipment rack by means of four rack screws fastened through the front mounting ears.

For safe, long-term reliability:

  • Ensure the ambient air temperature surrounding the EAS device is within the product’s specified operating temperature range.
  • Maintain adequate ventilation within the rack.
  • Ensure that adequate space exists on all sides of the frame for sufficient airflow. It is recommended a 1RU space be maintained between equipment, to avoid the transfer of heat between devices.
  • Ensure the location of the EAS device is accessible, dry, and free of dust.

Radio Antennas

The EAS device can be equipped with two or three (optional) internal radio receivers and connect using industry-standard F-type connectors for each receiver. If not equipped, each radio’s F-type connector will be covered with a cap plug. Review your state’s Emergency Alert System Plan for the appropriate monitoring assignments; these assignments will assist in determining the proper antenna for the frequencies that need to be monitored.

The EAS device’s internal radios are designed to receive the following frequencies:

FIG 9 Radio Antennas.JPG

For proper reception, use a good quality, shielded RG6 coaxial cable and connectors. The quality of the incoming audio signal will affect the operation of the audio decoders, and the quality of the forwarded audio messages.

Audio Wiring

Overview
The DASDEC-III platform has two types of analog audio: EAS Monitored Audio and Program Audio. EAS Monitored Audio Inputs feed the internal EAS decoders for processing. Only signals with EAS information should be directed to these inputs. Program Audio connections are used for internal switching of program audio.

Program Audio and Monitor 4 Wiring – Analog/AES Digital (optional)
The DASDEC-III utilizes RJ45-style connectors for analog and digital audio. These balanced audio outputs deliver a continuous audio program stream that switches between the Program Audio inputs and EAS audio during an alert.

The following wiring diagram illustrates the connections using common T-568B cabling.

FIG 10 Program Audio and Monitor 4 Wiring.jpg

Connection diagrams for EAS Monitor Input 4 (DAS3-EX/GX), Analog and AES Program Audio.

There are several sources for professionally terminated cables in various lengths and formats. One excellent source is Studio Hub (https://studiohub.com/adapters/)

AES Digital Audio Wiring
An optional AES audio input/output function is available for the DASDEC platform. This includes the capability for an AES digital audio output, along with a switching AES audio output when an AES audio input is connected. Refer to the diagram above for the cabling of the AES audio inputs and outputs.

EAS Monitoring Inputs
Radio signals for the DASDEC-III to decode EAS alerts can be received in two ways:

  1. Via internal radios, connect to your site’s antenna via a coaxial connection.
  2. Via external radios that pass on audio to the DASDEC-III via a line-in-jack.

Four connection options are available.

  • A line-in-jack connection with external radios using a 3.5mm jack. and
  • An additional sound card (EXP-EAS) with its 3.5mm jack.
  • Radio tuners Radios 1, 2, and 3
  • Monitor 4 input

See the back panel graphic on the next page for references to specific components.

FIG 11 EAS Monitoring Inputs.jpg

Back Panel View shown with optional EXP-2NICGIG and EXP-EAS monitoring audio expansion

  • Each audio line connector (3.5mm TRS) supports two EAS decoders. The left side of the input is decoded separately from the right side.
  • The line-in-jack option uses a monoaural connection, meaning that one 1/8 mini plug will need to be wired to provide the audio of two sources provided from external radios.
  • Refer to the diagram below:
  • The tip is left input, the ring is right input, and the sleeve is common ground.
  • Line-in-jack will utilize the blue 3.5 mm jack for main input 1 & 2 and if applicable the blue 3.5 mm jack on the sound card or aux input 3 & 4.

FIG 12 Monitoring Inputs.jpg

Video Wiring

HDMI-Video Output is a standard on the DAS3-GX model and optional for all other DASDEC-III units. When enabled, full-screen emergency alert details and accompanying audio is present during alert forwarding and/or alert origination via the HDMI connector on the back panel.

MPEG Encoder

The optional MPEG Encoder requires installing a “dongle” (shipped in the accessory kit) that must be placed on the VGA port. The system must have this installed during a cold start for the system to properly recognize that the port is active.

FIG 13 MPEG Encoder.JPG

General Purpose Input/Output (GPIO)

The EAS platform comes standard with two General Purpose Input (GPI) contact closures and two General Purpose Output (GPO) relays. The connector is located on the back panel, a 7-pin pluggable terminal connector is provided.

GPIO Terminal Connector

GPO relay outputs are programmable. Triggering can be filtered against specific alert FIPS Groups and EAS Group codes. Events that can trigger a GPO relay include:

  • Remain closed during EAS audio playout
  • Momentarily closed at start of EAS audio playout
  • Momentarily closed at start of an alert that has been decoded but not forwarded,
  • Remain closed if an alert is held or delayed pending a GPI action.

The EAS device comes with two General Purpose Input (GPI) contact closures. They can be programmed to trigger a variety of actions, such as:

  • Issue a Required Weekly test
  • Trigger origination of an alert header/attention signal, pausing for voice dub of the audio message, followed by trigger of the EOM audio
  • Review of audio portion of an active alert
  • Active alert acknowledgment
  • Forwarding of a monthly test with original audio
  • Re-enabling of active alert forwarding capability

Additional Expansion GPIO Options
For installations that require additional GPIs and GPOs, there are several options available that will expand the standard capabilities. An internal GPIO card may be installed in the PCI expansion slot to enable eight additional GPIs and eight additional GPOs. If the PCI expansion slot is unavailable, several network-connected GPIO devices, such as the R190A Remote LAN Hub Controller / Net GPIO, are options. The DASDEC platform can mix and match any combination of internal and network-connected GPIO devices.

Serial Port Wiring
Each EAS device has one RS-232 serial port on the back panel. The serial ports connect to and drive a variety of external video character generators and BetaBrite LED signs. The software supports a wide variety of serial protocols, including the most commonly used protocols in legacy EAS equipment, such as TFT Standard and Sage Generic.

An optional USB/serial port expander can provide up to four additional RS-232 serial ports. This option is useful when additional character generators and LED signs are needed.
Each serial port has the same pin-out, as shown below.

Direct Connection

FIG 16 Direct Connection.jpg

Direct Connection

1. Connect one end of the factory-supplied CAT-5 network crossover cable to the Main Network Interface port at the back of the EAS device and the other end to the network interface port of a standalone PC or laptop computer. Once the EAS platform is powered up and completely booted, it can be accessed via a web browser launched from the directly connected, customer-supplied standalone computer.

Attention
It is advised that you contact a network administrator before starting the following procedure, as a valid IP address and subnet mask settings are required to complete this initial setup. Working knowledge of how to change the network settings of the standalone computer is also necessary.

Hub/Switch Connection

FIG 17 Hub Switch Connection.jpg

Hub/Switch Connected

The primary difference between this type of connection and the direct connection method is the inclusion of additional networking hardware.

  1. Connect a standard CAT-5 network cable to the Main Network Interface port
    at the back of the EAS device and the other end into the open port of a routing hub or other network switching device.

  2. Once the EAS device is powered up, booted, and operational, it should be accessible via a web browser running on any remote computer on the local area network routed to see the address 192.168.0.200.
