1 DASDECIIHardware
1.1 Introduction
The DASDEC II is a 2U rack mounted unit built with the latest digital PC computer technology. It is an embedded PC
platform. The front of the DASDEC II, pictured below, provides a very simple face for a very sophisticated platform. The
DASDEC II exposes the PC motherboard connectors and single PCI slot in the rear of the unit.
Front panel of the DASDEC II
1.2 Front Panel
The front panel features a 2 x 20 character backlit LCD that indicates power-on and real-time device status. There are two
LEDs - one red, one green - to indicate specific types of status. A small grill provides space for audio from the internal
speaker. One push-button can initiate a simple weekly test.
1.2.1 LCD
The backlit green LCD shows real-time status of the DASDEC II. The LCD has numerous purposes indicating
system and/or encoding/decoding and active alert and button action status. Here is a list of information available
from the LCD.
When the DASDEC II is powered on, the LCD lights up, indicating power-on state.
When the DASDEC II begins to boot load system software, the LCD displays three phases of power up
disk check status, eventually moving on to display a busy booting indicator and the clock time. After all
system startup software is loaded, the LCD displays a startup message, eventually arriving at the ready
state where the first line displays DASDEC II: ON, followed by a crawling display showing the
programmed unit name, the software version number and the IP address. The second LCD line
continues to display the current clock time.
If the system software is manually stopped or temporarily restarted due to an internal problem, the LCD
will display a Server Stopped message until the software restarts into a ready state.
During decoding of an incoming alert, the LCD displays information about the source and the stage of th e
decoding.
While decoded, forwarded or originated alerts are active on the DASDEC II, the top line repeats,
displaying pertinent identification for each active alert.
If the front panel button is pressed, the bottom row of the LCD will display information about the button
push action. When the button push is to start a Weekly test, the display instructs of the need to push the
button once more in order to confirm the issue of the Weekly Test. When the button push is to
acknowledge an unforwarded decoded active alert, the display briefly displays the acknowledgment.
When a backup configuration is loaded or when the server software is restarted, the LCD will indicate
when the server is down or running again.
During a software upgrade, the LCD display will progress through server down states and eventually will
display "Upgrading'. When the upgrade is finished, the LCD will progress back to the original ready
state.
4 Digital Alert Systems: DASDEC User Manual
1.2.2 Status LED
The DASDEC II's two LEDS are used for a variety of status indications, making it easy to see the state of certain
important system information.
System Status - Green LED
When the DASDEC II is first powered on, the green LED is dark.
When the booting process advances far enough, the green LED begins to blink.
When the DASDEC II nears a ready state, the green LED blinks more rapidly. When the DASDEC II is
ready, the green LED light is on solid. A solid green LED indicates the DASDEC II is operational.
If the green LED starts blinking, the DASDEC II server has become non-operational. This can happen
during software restart or upgrades.
Alert status - Red LED
When the DASDEC II is first powered on, the red LEDs are dark.
After the DASDEC II becomes operational, in a ready state, with the green LED solid, the red LED
indicates decoding, alert sending status, and unacknowledged, unforwarded active d ecoded alerts.
If the red LED is blinking quickly, with pauses, the DASDEC II server is decoding an incoming alert. If the
red LED is solid, the DASDEC II is sending an EAS alert. If the red LED is blinking slowly and regularly,
an active alert has been decoded and has not been forwarded or acknowledged. Alerts are
acknowledged by pressing the front panel button or by pushing the Acknowledge button for the alert on
the Web browser. If the red LED is blinking quickly and regularly, an active alert is being held pending
GPI 1 input closure.
1.3 Back Panel
The back of the DASDEC II provides all of the connection ports. In addition to the standard PS/2 mouse and keyboard
and VGA monitor ports, the DASDEC II provides an RS-232 serial port (COM1), two RJ45 LAN ports, four USB ports,
main audio line in, out, and microphone jacks, optional auxiliary audio li ne in, out, and microphone jacks, radio antenna
jacks, GPIO, and a TV video out connector. The DASDEC II provides software support for the TV out as a licensed option.
The optional second audio sound card likely also has an unused MIDI interface port.

2 Setup:Hardware
2.1 Audio Wiring
Audio wiring on the DASDEC II has some flexibility due to the option of adding a second sound card and because of builtin software control. Here are a few rules:
EAS decoder input uses the analog audio line inputs or internal radio receivers.
Each available analog line input can be used for decoding audio provide d from an external receiver or another
EAS encoder. The web interface must be used to set an audio device input source from internal radios to line
input. Line input is NOT available on the AES digital card.
An audio line input supports two (2) EAS decoders. The left side of the input is decoded separately from the right
side. So two line inputs provide four (4) EAS decoders.
EAS alerts are selectively played out of the analog and/or digital line output ports. Software is used to select which
audio ports are used during alert origination and forwarding.
NOTE: The standard balanced audio hardware disables the main a udio line out mini-jack.
The Main analog audio output is instead routed out through the balanced audio output port. This output is
available on the screw terminal connector. The balanced audio hardware also features balanced stereo analog
audio input pass through for routing analog program audio through the DASDEC II. The inputs are also available
on the screw terminal connector. EAS alert play-out overrides the main audio output during the alert notification
(this is software configurable; the DASDEC II can be made to always override the input pass through source).
Audio pass through continues to operate when the DASDEC II is unpowered.
The main or aux microphone inputs can be used to record EAS audio messages. The ALSA sound software
option is required for these recordings to be clearly audible. DASDEC IIs come equipped with both OSS and
ALSA sound system options. The option can be selected from the Web interface by the Admin user.
AES Digital audio output is available as a hardware option. The AES option occupies one of the two PCI slots. It
provides both analog and digital audio output via two breakout cables. It also provides a separate output
monitoring analog mini-jack. The AES hardware option requires the ALSA sound system.
NOTE: Audio input and digital audio pass-through is NOT available w ith this hardware option.
See Section 1.5 later on in the manual.
For decoding, each side of the stereo input of any audio input can be selectively used as a singl e decoder source. In other
words, one stereo input supports two EAS decoders. A dual RCA to 3.5 mm jack input adapter can be used to connect
two separate mono input signals to a DASDEC II line input jack.
For alert encoding/origination, an audio cable is run from the main balanced audio output or from software selected 3.5
mm line output jack into your systems alert audio wiring. Only analog audio output is supported.
NOTE: The SPDIF digital audio output port is not used.
2.2 AES Digital Audio Wiring
The DASDEC II includes the capability for an AES digital audio output, and a Failsafe AES audio loop through. Refer to
the diagrams below for cabling of the AES audio inputs and outputs.
6 Digital Alert Systems: DASDEC User Manual
Diagram for Digital Audio Wiring
2.3 Video Wiring
Video output from the DASDEC II is an optional feature. When enabled, an NTSC analog composite vide o signal is
available from the RCA jack. This will provide a full details page during alert forwarding and /or alert origination. The video
page display takes a few moments to initialize. It will be steady when the GPO Audio or Video Output Relay is closed. It
will also be held until at least the Audio or Video relay is opened.
2.4 General Purpose Input / Output (GPIO)
The DASDEC II comes standard with two General Purpose Output relays and two General Purpose Input contact
closures. These are located in the upper middle of the back panel via a screw terminal connector. See the picture for
wiring info.
GPIO Terminal Connector
For DASDEC II's licensed for Broadcast features, both GPO relay outputs are programmable and triggering can also be
filtered against specific alert FIPS and EAS codes. GPO 1 is limited to Audio and Video events while GPO 2 supports
many other types of EAS events.
For non-broadcast DASDEC IIs, GPO 1 is non-programmable and is used as an Audio On-Air relay, being closed for the
duration of the EAS alert audio envelope play-out during alert origination or for warding. GPO relay 2 is still programmable,
but supports fewer options.
Digital Alert Systems: DASDEC User Manual
7
Examples of events that can trigger a GPO relay are EAS audio or NTSC video play-out of an alert, or when an alert has
been decoded but not forwarded, or when an alert is held or delayed pending a GPI action.
The DASDEC II comes with two General Purpose contact closure inputs. GPIO input 1 can be programmed to trigger
forwarding of an un-forwarded alert or hold/delay the play-out of an active alert. Depen din g on the DASDEC II option
licensing, GPIO input 2 can be programmed to a variety of actions, such as (1) issue a Required Weekly test; or (2) to
trigger origination of an alert header/attention signal, pausing for voice dub of the audio messag e, followed by trigger of
the EOM audio; or (3) review of audio portion of an active alert; or (4) active alert acknowledgment; or (5) re-enabling of
active alert forwarding capability; or (6) forwarding of a Monthly test with original audio.
See Chapter 4.11 Setup > GPIO: Setup General Purpose IO Options
2.4.1 Optional Expansion GPIO
The DASDEC II supports three different Networked GPIO hardware options. These modules provide a very
convenient and practical way of adding programmable relays and inputs to a DASDEC II system. T he DASDEC
II supports the Titus Technology WR-300 module with four relays (the same hardware as the Monroe Electronics
rack mounted R190 Hub Controller), and the Control-by-Web Web-Relay Quad with four relays (the same
hardware as the Monroe Electronics rack mounted R190A Hub Controller) and Control-by-Web Web- Relay Dual
module with two relays and two low voltage driven inputs. Web Relay Dual inputs require applied 3 to 12 VDC
(some industrial models 11 to 28VDC).
See Chapter 4.10.5 Setup > Net Alerts > Net GPIO.
2.5 Serial Port Wiring
The DASDEC II is equipped with one RS232 serial port on the back panel. In addition, one USB connect ion can be used
with a USB/serial port expander to provide up to four (4) more RS232 serial ports. The USB port expander requires an
FDTI chipset for compatibility. Digital Alert Systems can provide compatible adapters.
The serial ports are used to connect to and drive a variety of video character generators and Beta Brite LED signs. The
DASDEC II supports a wide variety of serial protocols, including the most commonly used protocols in legacy EAS
equipment such as TFT Standard and Sage Generic.
For configuration of serial port protocols, see Chapter 4.7 Setup > Video/CG.
Each serial port has the same PC pin-out as described below.

3.1 Power Up, User Interface and Initial Setup
The DASDEC II uses a standard AC power cord. It uses a single power toggle switch to power on.
NOTE: Power is supplied to the unit electronics while the external cord is plugged and
supplied with power.
There are two other ways to wire a network connection in order to use a Web browser user interface on a remote host.
The DASDEC II can be connected directly to another computer's Ethernet port using a network crossover cable, or can be
connected to a hub or router using a standard network cable. Network cabling may be d one at any time. The DASDEC II
is given a default static network address of 192.168.0.200.
No matter which way is used, the standard interface for configuring and controlling the DASDEC II is a browser based
Web interface.
NOTE: the DASDEC II must be fully booted before it can provide a network connection.
Once the DASDEC II is correctly wired; power up by pressing the power switch or rocker on the upper left corner of the
backside. The LCD screen will light up if power is applied. Allow the DASDEC II time to boot. The LCD screen and the
green system status LED will indicate when the DASDEC II is ready.
While the DASDEC II can operate with the KDE desktop enabled, the KDE desktop consumes much memory and extra
CPU speed. The provided KDE desktop applications are meant as conveniences and tools during DASDEC II
configuration. These should not be used indiscriminately during normal DASDEC II operation. Using applications from the
desktop during normal operation can interfere with the reliable performance of the decoder software.
3.1.1 Directly connecting a networked host computer
Once the DASDEC II is powered up, booted, and operational, it can be accessed via a Web browser from a
directly connected computer on the default DASDEC II network of 192.168.0.0.
Connect a CAT-5 network crossover cable, supplied with the unit, to the RJ45 port at the back of the DASDEC II
and to the RJ45 port of the network interface card (NIC) of a standalone PC or notebook computer. Configure the
standalone PC to use the static IP address 192.168.0.2 with a net mask of 255.255.0.0. After DASDEC II power
up and booting, it can be accessed via a Web browser on this host computer.
Now launch a Web browser application and direct the URL to http://192.168.0.200/. The DASDEC II will provide
a gateway page and quickly redirect to the DASDEC II login page. Follow the instructions in Chapter 3.2 Web
Server Login for logging into the DASDEC II using the Web login page. After login, the DASDEC II is ready to
use, although typically it will be desirable to reconfigure the network address. If the network address is changed,
subsequent logins need to use the new address in the http URL.
Follow the directions in Chapter 3 for general DASDEC II Decoder/Encoder setup via the Web browser
interface.
10 Digital Alert Systems: DASDEC User Manual
3.1.2 LAN connection with a networked host computer
Connect a standard CAT-5 network cable from the RJ45 port at the back of the DASDEC II into a routing hub or
other network switching device. You will likely need assistance from a network administrator to insure the
DASDEC II's default network address of 192.168.0.200 will be visible on the network, or will not clash with an
existing node (optionally, you will have to change the DASDEC II IP address using one of the methods described
above in section 3.1.1). Once the DASDEC II is powered up, booted, and operational, it can be accessed via a
Web browser from any remote computer on the LAN routed to see the address 192.168.0.200 (or whatever
address has already been used for the DASDEC II).
Follow the instructions in Chapter 3.2 Web Server Login for logging into the DASDEC II using the Web login
page. After login, the DASDEC II is ready to use, although typically it will be desirable to reconfigure the network
address. If the network address is changed, subsequent logins will need to use the new address in the http URL.
Follow the directions in Chapter 4 for general DASDEC II Decoder/Encoder setup via the Web browser interface.
3.2 Web Server Login
The DASDEC II features a built in Web Server that provides the user interface for all operations. This means the DASDEC
II can be operated over a LAN via any popular Web Browser. It also means that no special interface software or operating
system is required. When the DASDEC II is operated from a directly connected monitor, a built in Web browser is used
DASDEC II Web Browser Login Screen
To reach the DASDEC II Web interface from a browser, make sure the DASDEC II is on the same LAN as the browser
host and type http://<DASDEC II IP Address>
you must use https and a browser that supports 128-bit SSL encryption. When the DASDEC II successfully connects for a
Web session, it presents the following page in the Web browser.
Type Admin as the default user name
Type dasdec as the default password
Click the button. With the correct user name and password, the DASDEC II will login. If the user or password is
incorrect, the DASDEC II will display a message indicating the problem. If the DASDEC II is left unattended for 10 minutes
the idle logged in account will automatically logout. A message indicating session timeout will be displa yed on the login
screen. Multiple login sessions are allowed at the same time.
At the first login, DASDEC II will show the main tabbed page Setup with the radio button page Server in your web
browser (Setup > Server page). Subsequent logins will start at the last page displayed prior to logout.
(for example, http://192.168.0.200). If secure access has been configured,

3.3 DASDEC II Page Organization, Web Interface and Navigation
Each DASDEC II page has three sections:
TOP: the standard page header
MIDDLE: the interactive page
BOTTOM: a row of standard links
3.3.1 DASDEC II Page Header
The top section of every screen, or web page, has a standard header area with the following information:
DASDEC II Server Name
Four top level tabbed menu selections: Encoder, Decoder, Server, and Setup. A DASDEC II licensed as
both decoder and encoder displays four tabbed pages, including Encoder. A DASDEC II licensed as
decoder-only has three tabbed pages in the header; the Encoder page tab does not display.

3.3.2 Interactive DASDEC II Page
Below the standard page header is the interactive section of the DASDEC II page. This manual discusses each
section in detail.
3.3.3 Standard Links at Bottom of Page
At the bottom of each DASDEC II web page is a row of standard links. The links are:

to the DASDEC II Server > Logs > Web Session Log
3.3.4 Web Interface and Navigation
The DASDEC II uses a Web interface to setup, control, view status, and monitor all activity. Common web
interface commands are used. These include selecting radio buttons, toggle boxes or check boxes, entering text
in fields, pull-down menus and following active links. Commands can be entered with a mouse or the ke yboard.
The DASDEC II has three navigation levels. The first level is one of the three or four tabbed menus at the top
of the header: Encoder, Decoder, Server, or Setup. The second level is one of the selected radio buttons under
the tabbed menu. The page selected will show a darkened radio button. Most pages selected with a radio button
have a third level of navigation, which is a series of tabbed sub-pages. Some pages selected with a radio button
do not have multiple pages with sub-tabs.
To navigate, select one of the tabbed menus at the top. Then select a radio button. Then, if a level of sub-tabbed
pages is displayed, choose the page desired. When moving between top level tabbed menus, such as from
Setup to Server and Back
to Setup, the last selected location is remembered.
3.3.4.1 Back and Refresh Buttons
IMPORTANT! In general, DO NOT use the back button or the Refresh/Reload buttons on your browser.
Instead, ALWAYS use the DASDEC II and buttons. These are conveniently located in
both the standard header at the top of each DASDEC II page and in the row of links at the bottom of
each DASDEC II page.
Because the DASDEC II is a password protected Web interface, use the DASDEC II and
buttons when you want to go back one screen or reload the current page to current values. Although
using the browser's back or refresh buttons might appear to work, the DASDEC II page displayed as a
result may have misleading, out-of-date server state information. Also, in some cases, this can result in
unintended actions being performed.
3.3.5 How to Make Changes and Update
This manual informs how to make changes on each web page. Changes are typically made with toggle or check
boxes, selection boxes, buttons and text entry fields.
Toggle boxes are labeled as to the name of the feature the box controls. The feature is ei ther "Enabled" or
"Disabled". When the feature is "Enabled", a brief description of the feature usually follows, and the web page
instructs the user to click to disable the feature if it is not wanted. When the feature is "Disabled", the web page
instructs the user to click to enable the feature.
Many pages have an button, typically at the bottom of the screen. These pages allow users to
cancel changes before they are accepted.

3.3.5.1 Pages with an Accept Changes Button
On pages with an button, you must use the button to submit changes. Clicking on
the Accept Changes button updates the page information. If you exit the page without clicking on it, any
changes made are lost. When you return to the page, the page will still have the original settings.
On pages with an Accept Changes button, there will also be a button. Use this button
when you have made changes to the page, have not clicked the Accept Changes button, and want to
return all settings to the original settings.
3.3.5.2 Pages without an Accept Changes Button
Pages without an button make changes immediately through automatic page
submission. Changes made to check boxes, selection boxes, and by clicking buttons are immediate; the
page updates instantly. Pages with options that must change rapidly to be useful are the ones featuring
immediate updates. For example, changes on the Setup > Audio and Setup > Decoder > Forwarding
pages are immediate.
For text entry fields, generally you type the change in the field and then click the mouse anywhere on
the page, outside the text field box. The page updates immediately. (In this manual, the instructions for
text entry fields say, "Click page to change and update.") Some browsers also accept text entry
changes when you press the Enter key on your keyboard.

4.1.2 Configuration Management: Server Configuration Management
The interface on this page is used to manage configuration backup files. You can create a copy of the c urrent
configuration of DASDEC II settings and review previously saved configuration files. Each config uration backup
is stored in an encrypted ZIP file. The file contains all settings selected in the Setup process. The backup
configuration file does not
release 1.8-0, sound level settings are stored when a configuration backup file is created and are optionally
restorable. Configuration files made prior to 1.8-0 will load but do not contain audio level information and cannot
be used to set audio levels.
A recent backup configuration file is HIGHLY RECOMMENDED for a number of reasons. Backup configuration
files serve as a safety precaution. They provide a way to restore your DASDEC II settings in case of catastrophic
disk failure, or in the case of an upgrade error, or to restore the state of former DASDEC II settings when
experimenting with new settings. The backup allows you to easily and quickly return to the previous settings if a
serious configuration mistake is made. The backup configuration file can also be downloaded to another
computer for offline saving. Later, the backup configuration can be uploaded and reinstalled. The same
configuration file can be used to configure another DASDEC II EAS server.
When the DASDEC II is being configured for the first time, and before a backup configuration file is made, the
page states, "There are no backup configuration files yet." REMEMBER to return to this page to create a

Setup > Server > Upgrade web page
Upgrade DASDEC II Server Software from a DASDEC II RPM release file.
DASDEC II software upgrades are achieved by installing RPM package files. New DASDEC II software upgrade
files are periodically available and can be obtained from Digital Alert Systems Customer Service.
IMPORTANT: Always backup your DASDEC II server configuration before installing an update. Go to Setup >
Server > Configuration Mgmt page and click on the button. If you want, you can also download
any backup configuration file from the same page to a host computer for safe keeping. The 1.8-0 or later installer
automatically creates two configuration update files, one immediately before upgrade and one midway through
upgrade just before the current configuration files are modified by the upgrade. After the upgrade, these will
appear in the backup selection list on the Setup > Server > Configuration Mgmt page and are named
preinstall_2.0-0_config_1.zip and preinstall_2.0-0_config_2.zip. In case anything irregular happens during
the update, use your backup configuration file or one of these automatically created backups to re-install the
DASDEC II configuration settings.
The upgrade RPM file must be available from or on your local host computer’s file system to use this feature.
Type the path name of the file into the text box, or use the provided button. This will pop up a
browse dialog of your local computer's file system that will allow you to locate the RPM file and fill in the path
information. Select the correct RPM file once it is found. Then, click .
A confirmation page allows you to continue with or cancel the upgrade. After accepting the upgrade, an error
status is returned about the file if it is not an acceptable DASDEC II upgrade file. Otherwise, you will be logged
off the DASDEC II Web interface and will be directed to log back in after a short waiting period. The upgrade
should only take about a minute to complete. And to just emphasize the obvious but important, do not power off
the DASDEC II during the upgrade! The front panel LCD will display a message during the upgrade process. It
will also indicate when the DASDEC II is back to a login ready status.
Show Auxiliary Package Information
The main DASDEC II RPM software package is named 'DASDEC. Clicking on the button
expands the upgrade page to display auxiliary feature/securit y related packages that
can also be upgraded using the upgrade interface. Each auxiliary package is displayed along with an explanation
of its function, the currently installed version, and the latest known version (as known to the currently installed
Digital Alert Systems: DASDEC User Manual

DASDEC II package).
This expanded view also includes a special button for repairing the internal
package database. Use this button to repair the RPM package database in case of package installation f ailure
due to RPM database corruption. THIS COMMAND SHOULD RARELY, IF EVER, BE NEEDED!
Once the packages are reviewed, click the button to set the page back to the simple
upgrade interface display.
4.1.4 Options
Platform Configuration Options
Use this interface to set various platform options.
Server Debug Log Interface: This option enables or disables the DASDEC Debug Logs. This log is another
way for customer service at Digital Alert Systems to be able to view what is happening inside of the
DASDEC. If this option is enabled your DASDEC will keep track of these logs.
Select USB Port Speed Option: This option allows you to change the speed at which data is transferred
via USB in the DASDEC. This feature is important for some USB to Serial applications, where the USB to
Serial device may only support USB 1.1 and not USB 2.0. USB 1.1 Serial Adaptors need to run with USB
1.1 speed.
4.2 Setup > Network: Setup Network
There are two tabbed sub-pages on the Setup Network page: Configuration and Sec urity. Use the sub-pages to
configure the DASDEC II to operate on a network by entering such information as:
DASDEC II main and auxiliary network addresses
DASDEC II network server hostname
Static IP address
DHCP to automatically acquire an IP assignment
Netmask, optional DNS (domain name services), and an optional gateway value.
Force use of secure http when using the Web browser.
Management of ssh keys over a group of networked devices.
4.2.1 Configuration: Server Network Configuration
This page displays the current network state of the DASDEC II and provides interfaces to configure Server
Network Hostname, network Ethernet IP addresses, network gateway, and the static routes. It also displays four
informational sections about the current network configuration. These are the current network routing table, static
routes, network address configuration, and the contents of the /etc/hosts file.
The DASDEC II server can be configured to have static IP addresses or can use DHCP to automatically assign
network addresses. A second network interface can also be configured with a static or DHCP address. The
second network interface will only be enabled if the correct hardware is installed. Presently, the plug and play
USB-Ethernet Adaptor "Belkin F5D5050" is supported. Specific Ethernet PCI cards have not been tested or
approved, although many will work. The second network is usually meant to provide control and management
into a system that will use the main network for streaming MPEG, SCTE-18, or for sending other network based
alert data.
When a DASDEC II network interface is valid and operational, the web interface configuration box is dis played in
green and labeled "Enabled". Else, the interface box is the backgroun d color and labeled "Disabled". In the
example above, the main network interface is configured and enabled but the second network interface is
disabled, although it is fully configured, and is selected to be available. This would happen if the Ethernet adapter
is not present (for example, the USB-Ethernet adapter is unplugged).
24 Digital Alert Systems: DASDEC User Manual
The primary network interface on the DASDEC II defaults to a static IP address of 192.168.0.200. This is a
commonly used, non-public IP address for LAN based appliance hardware. This value is meant to be changed.
The default IP netmask is 255.255.0.0. No default DNS or gateway is configured. If the gateway is selected, it
defaults to 192.168.0.1. The currently used IP address is displayed just above the entry field for the Server
Network Hostname. Information on other important system network configuration is displayed on the bo ttom half
of the page. See subsequent chapters for more information.
To save changes to the Network Hostname, Gateway, IP address or Second network interface option, you must
click .
Setup > Network, Server Network Configuration (top half of web page)
4.2.1.1 Server Network Hostname
When configuring more than one DASDEC II, pick a unique Server Network Hostname. The name
cannot contain spaces.
The Server Hostname is different from the DASDEC II server name. (See Chapter 5.1.1 Main/License:)
The DASDEC II server name is the name the DASDEC II presents through its Web browser interface. It
serves to allow for simple identification of a viewed DASDEC II.
The Server Network hostname is the network name of the DASDEC II as defined by the underlying
Linux operating system. This name can also be very important for correct functioning of email.
Some email systems require a fully qualified network hostname (e.g. DASDEC II.mysystem.com).
If the DASDEC II has been given a network name by a system administrator, this name must be
entered here.
Digital Alert Systems: DASDEC User Manual

To submit changes to this name, you must click .
4.2.1.2 Network Gateway Configuration
Three radio buttons are provided to select a gateway route option. The selections are No Gateway,
Main Interface, or 2
access to the internet or to other networks within a LAN, or if the DASDEC II will be multicast streaming
either MPEG Audio/Video or SCTE-18. If a gateway is required, either network interface can determine
the gateway address range; but there can only be one gateway, and it must be within one of the defined
networks. If a gateway option is selected, enter the IP Address of Gateway within the chosen network.
Although not required, the common value for a gateway address ends in 1 (#. #. #. 1).
To submit changes, you must click .
4.2.1.3 Network Address Configuration
The DASDEC II network IP address can be manually configured to a static IP address or automatically
configured to a dynamically provided IP address via DHCP. Select the desired Network T ype bas ed on
your system requirements.
Network Type: Static (Manually Configure), Set the IP address manually)
To set a new static IP address, select Network Type > Static and then fill in the values for the
desired IP address and IP Netmask. If Domain name service resolution is needed, also select Use
DNS? and enter the corresponding values. The example above shows a ne w IP address of
192.0.0.23 and a netmask of 255.255.255.0, as well as a DNS (nameserver only) a nd gateway
configuration. DNS converts named IP addresses into the underlying numeric IP address.
DNS must be used if you configure any named IP addresses on the DASDEC II (instead of
numeric IP addresses). A likely requirement for DNS is to resolve an email server name.
To submit the new values, click .
Network Type: Automatic (via DHCP), Set the IP address via DHCP
DHCP is a very convenient way to network a computer. It requires that your LAN be running an
accessible DHCP server. When DHCP is used, the IP address, the netmask, gateway and a DNS
server are automatically granted. To use DHCP on the DASDEC II, select Network Type >
Automatic (via DHCP)
nd
Network Interface. A gateway is needed if the DASDEC II is to have direct
. See screen shot below.
Setup > Network : DHCP Network Configuration
Then click . Once the DHCP setting is accepted, the DASDEC
II will log you off. After a few seconds, you can log back in on the redirected address on the Login
page, as before.
26 Digital Alert Systems: DASDEC User Manual
IMPORTANT! You must be CAREFUL when configuring a static network address if you are
configuring from a remote host. If an address which is inaccessible to your network is accepted for
the DASDEC II, you will not be able to log back in from the remote host.
Second network interface option
The Second Network Interface checkbox below the main Network configuration box controls use
of an optional second network interface. The default is value for this option disabled. Check to
enable display of a configuration interface for a second Network Interface Card (NIC) adapter.
As stated above, this interface will display in green and show a status label "2nd Network is
Enabled" when the adapter has been properly installed and configured. When enabled, it will also
display the IP address currently in use for the adapter.
Configuration of the second network adapter is similar to the main network. You must choose a
Network Type from Static (Manually Configure) or Automatic (via DHCP). If Manual Configuration is
chosen, enter the IP Address and the Netmask. The network part of the IP address for the second
network must be unique compared to the main interface network! Otherwise, either interface will
probably not function. For example, if the main network is 10.0.1. #, an obviously separate network
would be 192.168.1. #. There is not a separate DNS to configure for the second network. You can
also optionally set the hostname for the second network as it appears in the Linux /etc/hosts file.
When options have been configured, you must click .
4.2.1.4 Network Status Information
Tables at the bottom of the Setup Network Configuration page show the current network routing
table, static routes, address configuration, and the /etc/hosts file. This information is provided to help
with network configuration and troubleshooting. The information is directly generated from Linux
network status applications and reflects the actual state of the DASDEC II network configuration. If the
network configuration is damaged, it is possible for the information in this table to not match the
configured values displayed in the user interface fields. The information in this table is definitive and
accurate.
Perhaps the most useful information is provided within the Current Network Configuration section.
Under the eth0 table is the IP address as the Linux OS sees it. This is the value provided next to the
label "inet addr:”. When a second network is enabled, a separate table will be shown for eth1.
4.2.1.5 Static Route Configuration
This simple interface allows statically defined network routes to be enabled or disabl ed and
added/deleted at network startup. Click the toggle box to Enable/ Disable a specific static route.
Digital Alert Systems: DASDEC User Manual
27
Setup > Network > Server Network Configuration (middle section of web page)
Static routes persist between rebooting of the DASDEC II. The DASDEC II comes preconfigured with
two static routes, either of which may need to be disabled depending upon the local area network.
These are 10.0.0.0 and 192.168.0.0. If the DASDEC II will be configured to run on a similar network, for
example 10.100.1.0, it is very likely that the default static-route of 10.0.0.0 should be disabled or
deleted.
NOTE: A conflicting route can block network connectivity.
Use the interface to control these requirements. The default static routes allow a DASDEC II to connect
to a 192.168.0.0 and 10.0.0.0 network by default, out of the box. Use this interface also to add other
needed routes out of your network. The provided user interface directly edits the file
/etc/sysconfig/static-routes. It is safe to directly edit this file as long as care is taken not to corrupt the
file. The contents of this file are displayed.

4.2.2 Security: Server Network Security Configuration
This page provides controls for managing network security. Two features are configurable for network security.
You can switch web access between secure mode (https) and regular mode (http). You can also use this page to
manage Secure Shell (SSH) keys across multiple platforms.
Web Interface Access Security
Use the Web Interface Access Security checkbox to force http SSL based communication to the Web Server.
The box is labeled Check To Only Allow https Secured Web Access to this server. If the box is checked,
browser access is forced to be via http. The change is immediate. All communications to the server will be
encrypted. Digital Alert Systems strongly recommends using this setting if the DASDEC II will be on a public
network
SSH Key Management Interface
WARNING: DO NOT MODIFY any SSH Keys without consulting with the factory!
Secure Shell is used for EAS NET network communication/control between a DASDEC II and other EAS NET
compatible platforms (including other DASDEC II's). SSH is a secure communications method that relies on
public/private key encryption. For a DASDEC II to communicate with another platform via SSH, the public key
from the DASDEC II's public/private key pair must be "authorized" on the remote platform.
Authorization usually is achieved by copying the public key into a file on the remote host. The DASDEC II uses
the open source package OpenSSH for SSH features. This package has a file called "authorized_keys2" under
/root/.ssh/ to hold the authorized public keys from remote platforms. Authorization allows secure access only
from the holder of the public key's corresponding private key. Even though this method of encr yption and secure
access is very safe, it is still as a good idea to update the public/private keys from time to time. This can be
tedious to do manually between a set of servers that already intercommunicate. The DASDEC II SSH Key
Management interface greatly simplifies this process. It allows a group of remote hosts offering SSH connections
to have all of the encryption keys updated from the current DASDEC II location. This updates and maintains
secure SSH based network interoperability for EAS NET across each platform with a single operation.
Digital Alert Systems: DASDEC User Manual
29
To use this interface correctly, you must add client interface descriptors for each remote platform in the managed
group. The button is used to create each descriptor. When a descriptor is added using this button,
there is no need to confirm the addition. The screen shot below shows a single remote client descriptor that was
added using . Add as many as descriptors as needed. (EAS NET allows up to 8 connections.)
SSH Key Management Interface
Once a remote host client descriptor interface is added, it must be configured. Reasonable default values for
SSH connection to the remote host are provided (except for IP address). Type in the IP Address and change the
remote host User name, the SSH configuration path (directory), the SSH authorized keys file name, DSA public
key and private key file names, and management status file name if needed.
Changes to these Host text field values are not saved until you click . You can
cancel changes by clicking the button.
A very useful feature of this interface is that it provides network connection tests to remote hosts. Set the selector
SSH Connection Test to the desired test and click the button .
You can try a variety of tests to prove SSH connectivity as well as network connectivity via "ping". Six tests are
supported:
1. "Ping". Use a simple network ping to test if the base network route to a remote host exists. To test
basic network connectivity, the ping test can be used without regard to the SSH field configuration.
Set the IP address (numeric dot.decimal format unless DNS is enabled) and run the Ping test using the
button.
2. "Uname" query via SSH (see example above). This will attempt to get the operating system name from
the remote host.
3. "Date" query via SSH. This will attempt to get the date and time from the remote host.
4. SCP test via SSH. This will attempt to copy a test file to the remote host.
5. "Key Management Status" query via SSH. This will attempt to retrieve the current state of the DASDEC
II key management status from the remote host.
6. "Get Public Key" query via SSH. This will attempt to retrieve the public key from the remote host.
Select a test and click the button to see the test results. Be patient; it can take several seconds to
run some of these tests. Results are printed just below the button.
30 Digital Alert Systems: DASDEC User Manual
When you have all of the remote host descriptors entered properly, and you have confirmed SSH connectivity to
each remote host, you may safely update the public/private keys for the entire group by clicking on the button
. You may also return to the prior set of keys by clicking the button
.
The status of the last group management operation is printed just below the button.
This gives a date and useful information about the last SSH management operation performed from this
DASDEC II.
The page display areas below the SSH Management interface provide two more useful pieces of information
about SSH. The first display shows the current SSH DSA Public Encryption Key and its installation date. Belo w
this is a printout of the "authorized keys" file. This shows remote hosts authorized for SSH connections to this
DASDEC II.
4.2.3 Proxy
Current Optional HTTP/HTTPS Proxy server assignments for getting CAP data
The server can be optionally configured to access remote http and/or https data (for CAP data) via a defined
proxy server address. Enter the hostname:port in the appropriate field. This option would be enabled if the user
wanted to use defined proxy servers for CAP data acquisition via HTTP/HTTPS.
4.3 Setup > Time: Server Date and Time Configuration
The Setup Time page allows the hardware clock on the DASDEC II to be set. Date, time, and time zone may be set.

Make changes to date and/or time and/or time zone, and then click Submit Date/Time/ Time zone Changes. If time
zone is changed, the DASDEC II will restart, and you will be forced to log back into the Web interface. If the time is set
forward far enough, you will also be forced to log back into the DASDEC II Web interface.
Official time link
If your browser has Internet access, click this link to pop-up a web page that displays the current official time.
Network Time Protocol (NTP) Configuration
The DASDEC II supports Network Time protocol (NTP) to synchronize its clock to another clock over a network. This will
synchronize the DASDEC II to an atomic clock over the Internet, or to another computer running NTP on your LAN, or to
another DASDEC II running as an NTP server on your LAN.
NTP Server name or IP Address:
Enter a name or dot notation IP address of a remote NTP server that is accessible from the DASDEC II LAN.
[ ] The checkbox for NTP must be checked to start NTP. If no NTP server name is entered and NTP is enabled, then the
DASDEC II will become an NTP server that can be pointed at from other DASDEC IIs over the LAN.
NTP Server Info
This is an informational display area that provides status about the NTP connection. Use this information to verif y the
time offset between the DASDEC II and the NTP source server.
Public NTP Servers
Public NTP servers can be viewed by following the link provided.
NOTE: The computer hosting the Web browser must have Internet access to follow this link,
and the DASDEC II must be able to contact the chosen NTP server.
4.4 Setup > Users
The Setup Users page is to manage user accounts on the DASDEC II Web Interface. Only accounts with Administrative
permission are allowed into this page. Keep in mind that these user accounts are separate from the Li nux system user
accounts. They do NOT control permissions to login to the base Linux system. From the Setup Users page, you can add
and delete user accounts, change the account Web Interface passwords, and set user permission levels. The Admin
account cannot be deleted, and only Admin can change the Admin password. Non-Admin accounts can be used to allow
users different levels of access. For instance, creating a user with View Only Level permission would allo w EAS alert
activity report downloads without risking the chance of accidental changes to DASDEC II settings.
32 Digital Alert Systems: DASDEC User Manual
Setup > Users web page
The DASDEC II allows multiple active user sessions. The same user or different users can be logged in more than once
and at the same time. A count of the number of active sessions is provided in the page header display on the right side of
the User:'accountname' text display. For instance, if Admin is logged on twice, the header displays User:Admin(2). The
total number of active sessions is displayed if that number is greater than the current user sessions. For instance, if Admin
is logged on twice and another user is logged on once, the header will display User:Admin(2)(3). Every active session is
managed separately; the page location within the Web interface can be different for the same user logged in twice.
However, keep in mind that virtually all of the provided controls and settings apply globally to the DASDEC II platform. If
two users with edit permissions are changing the same control (for example, tuning the radio), the last one to set the value
"wins". Refreshing the displayed page will display any changes mad e by other logged on users.

4.6 Setup > Audio
Audio is at the heart of an EAS system. From the factory, a DASDEC is configured ready for average field situations. The
EAS in your specific area could require some special tuning. At minimum, you will need to use the Setup Audio pages to
tune the Radio stations used for EAS monitoring. You will also likely need to adjust the decoder input levels for the
selected stations, since every station will vary in its signal strength. The audio output levels may also need some
adjustment to fit with your broadcast parameters.
38 Digital Alert Systems: DASDEC User Manual
The Setup Audio pages provide a variety of easy-to-use con t rols and status displays to facilitate these tasks.
Due to the need for immediate feedback when tuning audio, the Setup Audio pages do NOT have an Accept Changes
button. Changes to check boxes, selection boxes, and clicking buttons on these pages are immediate.
NOTE: Some browsers will not accept the text edit change to an audio level until the
mouse is clicked outside of the field entry box. Other browsers simply will accept the
change when the Enter key is touched. You may wish to review Chapter 3.3.4.2 How to
Make Changes and Update.
There are four tabbed sub-pages on the Setup Audio page: Decoder Audio
and Radio Tuners. Start with Audio Output Levels/Tests.
4.6.1 Audio Output Levels/Tests: Direct Audio Output Levels and Tests
The audio output levels for the DASDEC audio output device ports are configured from this page. In addition, the
output sample rate and the audio preview devices group are configured here. Each audio output device results in
an audio configuration interface on this page. Finally, audio W AV and MP3 files can be uploaded into the
DASDEC from this page.
All standard DASDEC(s) from the factory have a Front Panel speaker, a Main audio output device, and one
auxiliary audio output device. A labeled configuration table is provided for each one of these output devices. The
configuration table provides controls for setting output levels from 0 to 100% and for running audio tests. The
table also displays if alert origination and forwarding will use the specific audio output. For the main audio output,
a toggle control is provided for enabling or disabling the analog audio pass-through option.
One other audio output option available that affects the page display. A second analog PCI soundcard can be
added in the factory to provide two extra decoders (for a total of six). This will result in a second auxiliary audi o
device configuration table labeled Aux 2 Audio.
Audio tones can be played through each available audio output to test audio connections and calibrate levels
using audio test equipment. Configure the levels by entering numbers from 0 to 100 for any spec ific port. Output
level values near 70 are a good starting point for the DASDEC. Each audio device displays the same style of
table for the control interface. The table allows audio output level control, audio tests, and audio enable/disable
for alert forwarding and origination audio.

Main Audio and Aux Audio Tables
The interface tables for Main and Auxiliary (Aux 1 And Aux 2) audio operate much like the Front Panel
Speaker table described above. Auxiliary Audio is optional and thus may not appear. It is possible to have
two auxiliary audio interface tables. Also, Auxiliary Audio provides stereo output volume level control.
Otherwise, the same audio tests and alert audio toggles are presented.
Forwarding/Encoder Output Enable & Main Audio / Passthrough Audio
The Main Audio table has a special checkbox that controls the state of the Main analog audio pass-through
circuit. This circuit controls analog audio input/output pass-through on the screw terminal connector on the
back of the DASDEC. Pass-through audio allows external balanced audio to be passed throug h the
DASDEC and interrupted during an EAS audio activation.
If the Main audio output is to be tested by playing a file or a tone, or if pass-through audio is not needed, the
Main Analog Audio Passthrough toggle should be disabled. This will enable full time output of DASDEC
internal audio. Otherwise, check to enable analog audio pass-through. When Pass-through is Enabled, the
only time DASDEC generated audio is played on the Main audio output port is during an EAS alert.
Tests: To test the Main and/or Auxiliary Audio outputs, attach speakers to the DASDEC audio device output
ports and run the various tone test buttons. These tests allow the DASDEC to play each of the two single
tones that comprise the dual-tone EAS Attention Signal. The EAS Attention signal and WAV files can be
played as described above for the front panel speaker interface table.
Setup > Audio > Audio Output Levels/Tests web page, bottom sections
Alert Forwarding and Alert Origination: The Main and Auxiliary Audio tables display an active hyperlink
showing whether the forwarded and originated alert audio is output on the audio device. To make changes
to these states, click the text link to jump to the correct Decoder or Encoder Audio setup page and modify
the associated checkboxes.
5. Upload Audio .WAV file to DASDEC Server
The interface at the bottom of the page allows Wav and MP3 files to be uploaded into the DASDEC. Click
to locate the file on the host computer file system, then click . MP3 files will be
converted automatically into a WAV file on the DASDEC. Uploaded audio files are available for tests as well
as for encoding and manual forwarding.
4.6.1 Radio Tuners
The standard DASDEC supports three internal radio receivers. These can be configured, tuned, an d monitored
on the Radio Configuration page. Each radio can be programmed to any AM, FM, or NOAA frequency.
NOTE: External antennas are usually required for proper radio reception. Antennas are
connected to a coax connector on the back of the DASDEC II. Antennas can be
purchased through third party vendors. For recommendations, contact Digital Alert
Systems.
42 Digital Alert Systems: DASDEC User Manual
Setup > Audio > Radio Tuners web page
For a radio to be used by a decoder channel, the decoder must be set to the internal audio source that indicates
a radio is available (displayed per decoder under the Setup Audio > Decoder Audio page).
NOTE: It is important to tune the radios to stations that carry EAS alerts. This is a
fundamental part of setting up your DASDEC II for monitoring the Emergency Alert
System.
The chosen radio frequency settings are automatically recalled at boot time or whenever a software restart is
done. A numeric level indicator displays the strength of reception. FM, AM and NOAA band selection occurs
immediately. NOAA frequency selection occurs immediately upon button selection. Typed frequencies for AM
and FM must be submitted using the button.
As a convenience, the decoder channel associated with each radio tuner is displayed in an active web link. This
can be clicked to immediately traverse over into the Setup > Audio > Decoder Audio page.

NOTE: It is VERY IMPORTANT to verify radio reception and decoder input levels
after tuning. Radio reception can be monitored using the provided Listen on:
buttons for each radio. When you select one of the speakers listed, audio from the
associated decoder for the radio will play-out of the chosen output. To stop the audio
play-out, click on the Turn Radio Monitoring Off button that will be displayed above the
radio tuning sections. Radio frequencies can be tuned while listening.
NOTE: DO NOT LEAVE THE MONITOR ON DURING NORMAL OPERATION
NOTE: The Decoder Audio Monitoring interface provided on the Setup Audio > Decoder
Audio page can also be used to listen to radios. It is less convenient than using the
buttons provided on the Radio Tuners page. It is necessary to use the Decoder Audio
Monitoring interface to listen to the fourth decoder input or to listen to decoders five and
After tuning and verifying reception, check the input levels on the Setup Audio > Decoder Audio page and
make sure they are rated as OK (or occasionally Elevated).
4.6.2 Decoder Audio: Alert Decoding Audio Configuration
The Decoder Audio page has three areas to configure: Alert Decoding A udio, Decoder Audio Monitoring, and
Alert Forwarding Audio Configuration. For Administrative users, a fourth configuration option, Sound System
status and configuration, appears at the bottom of this web page.
Each EAS decoder channel can be independently tuned for input sensitivity and can be ena bled and disabled.
Decoder input can also be heard using the audio monitoring controls on this page. T he audio output devices
used during alert forwarding are also configured from this screen.
To make changes effective on Setup Audio web pages, see NOTE under the Chapter 5.6 Setup > Audio.
1. Main and Auxiliary Audio Decoder Configuration
Each analog soundcard (Main, Auxiliary) has its own decoder status and configuration di splay table.
NOTE: the AES digital audio card does NOT support EAS decoding. Each table
has a radio button selector for the Audio Input Source. Each soundcard supports two (2)
decoder channels. Decoders can be selectively enabled and disabled an d the input
levels can be set. The interface is described below.
Soundcard name and associated Linux mixer device
The name of the soundcard and its associated Linux mixer device name are shown above the display table.
Audio Input Source: Internal/Radio or Line-In Jack
To the right of the soundcard name is a radio button control that indicates the analog aud io input source for
the soundcard. This can be Internal Radio or Line-In Jack. The input source selection switch is VERY
important since it controls the origin of the audio input stream used as the EAS audio source. Typically this
will be set to the Internal/Radio setting for the Main Audio device. To connect external radio receivers, use
the Line-In Jack setting on the appropriate sound card device.
If Radio is selected, a link to the Setup > Audio > Radio Tuners page is provided in the first column on the
display table as a convenience.
The standard DASDEC has three built-in radio receivers. Two are connected to the main audio device. The
third is connected through the Audio Input Source "Internal A" connection. A fourth audio source, from the
back panel screw connector terminal, is also routed through this input channel.
44 Digital Alert Systems: DASDEC User Manual
When a new input source is established, refresh this page a few times to insure a consistent level quality of
OK. This page redisplays more slowly than most other DASDEC web pages, so be patient when you
access or refresh this page.
Soundcard decoder pair display table
Each table provides names and controls for two decoders to be selectively enabled and disabled and for
decoder input levels to be set. Typically, all decoders can be enabled. The DASDEC-1EN supports two EAS
decoders per stereo line input channel. This results in each soundcard device provi ding two decoders, one
on the left channel and one on the right channel (L1 and R1). Each decoder is disp layed in a separate row in
the soundcard status table. Each row has four columns to review and configure.
The audio soundcard table columns are:
1) Decoder Name, Label and Info – The decoder base name, automatically set by server, provides an
identification tag for the decoder. The input text field provides for each decoder channel to be giv en a
user label for identification of the channel in other interface pages. Also, if the Audio Input Source is
set to Radio, a link to the Setup > Audio > Radio Tuners page is displayed as a convenience.
2) Audio Input Level (1..100) – Change the input level as needed until the Audio Level Status is OK
(green) or occasionally Elevated (yellow).
3) Audio Level Status – EAS Decoding is sensitive to audio input levels. Input level status is
automatically rated at Zero, Low, OK, Elevated, or High and color coded. The quality of the input level
is constantly being rated in real time per decoder on the DASDEC server. When you use the
button in the standard header of the page, the Audio Level Status quality is redisplayed. This assists
in setting the correct level setting.
Each decoder is also given a button. When a button is clicked, a WAV file of the
corresponding decoder audio input buffer is saved on the DASDEC, dated, and displa yed as a web
link accessible via this web page. This can be a great aid for troubleshooting and testing audio.
The file is named based on the decoder channel name and can be downloaded via the provided web
link. In the screen shot, four snapshot files are shown:
L1 snapshot (Fri Jan 4 16:38:38 2008): L1_snapshot.wav
L1 Last Post Decoded Alert Snapshot (Tue Jan 8 09:19:26 2008):
L1_post_alert_snapshot.wav
R1 snapshot (Fri Jan 4 16:36:32 2008): R1_snapshot.wav
R1 Last Post Decoded Alert Snapshot (Wed Jan 16 11:17:12 2008):
R1_post_alert_snapshot.wav
Two of these are snapshots generated by the button, the other two, Post Decoded Alert
Snapshots, are generated automatically after decoding has finished. See the Decoded Alert Auto-
Snapshot option below.
4) Decoder Enable – Two toggles are provided to enable/disable a decoder and EAS Auto-scale. A
decoder must be enabled to decode EAS alert audio.
EAS Auto-scale is a method to automatically increase the input gain level when EAS alert data is detected.
This can result in decoding alerts that have low audio levels from the source.
Decoded Alert Auto-Snapshot checkbox
A toggle box located below the decoder status/configuration tables allo ws you to enable or disable the
Decoded Alert Auto-Snapshot. This feature should usually be enabled. It results in a snapshot WAV file
being generated after an alert is decoded or after a decode error is detected. This feature allows detailed
troubleshooting in the case where incoming EAS audio has resulted in decoder errors. Careful analysis of
the post-alert snapshot audio can pinpoint the nature and source of upstream EAS errors.

4.6.3 Encoder Audio
There are two main configuration options for encoder audio: Alert Encoding Audio Configuration and Alert Audio
File Recording.
1. Alert Encoding Audio Configuration
When the DASDEC encoder is used to originate an EAS alert, the audio associated with the alert must be
played out of an output port in order for the alert to be transmitted or decoded by another decoder. The
audio for the alert must be configured to play over a selected audio output. This interface allows for setting
audio sample rate, enabling/disabling Originating audio on each of the audio output devices, and for setting
a play-out delay time.
Audio Output Sample Rate
This selector controls the sample rate of audio played from the DASDEC.
NOTE: This same control is presented under Setup > Decoder Audio > Alert Forwarding
Audio Configuration and under Setup > Audio Output Levels/Tests. The sample rate
applies to audio for both alert Forwarding and Origination.
NOTE 2: AES Audio output requires 32000 or more samples per second.
Main Audio and Auxiliary Audio Tables
These tables allow for examining audio output status and enabling/disabling playing base station
alert audio on the individual audio output devices. The Main audio device is always present on a DASDEC.
Auxiliary Audio outputs are present if an appropriate sound card has been installed. A standard DASDEC
always has the Aux 1 sound device. The table has two columns: Audio Output Level and Encoder Output

2. Select audio device for alert audio file recording
The DASDEC Encoder provides an interface to record audio into WAV files (EG. the audio file recording
interface is available under the Encoder > Send EAS > General EAS web page). These files can then be
used for the voice audio portion of an EAS alert. This page provides for selecting which audio device and
input source (microphone or line input) is used for the recording.
NOTE: An active link to this page is provided wherever the audio recording
interface is presented.
Use the ALSA sound system when directly recording WAV files on the DASDEC. ALSA supports a mic
boost that results in clearer, louder, audible recordings.
Sound card source - The standard DASDEC provides one Auxiliary Audio card in addition to the Main
audio card. When more than one sound card device is present, a radio button selection option for the
recording sound card will be displayed. Select the card to use as the recording source.
Input Source - Once the source sound card is selected, set the Input Source to either Microphone Input or
Line Input Left. The selection is determined by the actual source from which you will record.
Record Input Level - Use the Input Level control to set the level for the recording input gain level. Enter a
value from 0 - 100 in the Record Input Level field. After you set the value, you must click on the text "(click
here to activate changed value)".

The Main Serial sub-page has three sections: Serial Port Character Generator Configuration; selected CG
Attribute Settings; and FIPS and EAS Codes filter configuration. Information in each section is reviewed below.
1. Serial Port Character Generator Configuration
The radio selection buttons show the Character Generator (CG) used when a decoded alert is for warded or
encoded (or no CG). There are eight supported character generator protocols: Monroe Envoy, Monroe
CEMS-0500/1000, Standard TFT, Chyron CODI, VDS 840, Sage Generic CG, DecadeNet XBOB, and
BetaBrite LED sign. Of these, the Monroe CEMS-0500/1000, VDS 840, and DecadeNet XBOB require a
DASDEC II TV license. The Chyron CODI interface requires both a DASDEC II TV and a Plus Package
license.
Choose the appropriate protocol for the connected serial device and check that option. T he CG should be
connected to the server serial port (on the back panel) using the correct serial cable (TFT, CODI, VDS use
NULL modem cable, Monroe CGs use straight through cable, SAGE Generic depends on specific CG,
usually a straight through cable). Use SAGE Generic for Evertz MediaKeyer and Logo Inserters as well as
for Miranda Imagestore Cgs. Most of the character generator protocols present some further configuration
options. Some, like Chyron CODI and VDS840 present direct control of ale rt repetition, font colors, number
of crawl loops, etc. Experiment with these settings to get the desired behavior. The CODI protocol also
presents options for generating test patterns. Most CG's also can be configured to run repetitions of the
video output during an alert. The available CG's and protocols are described in Chapter 9 - DASDEC II
Peripherals.
2. CG Attribute Settings
The options displayed here depends on the selected CG protocol. The screenshot shows the SAGE Generic
CG has been chosen. So, for SAGE Generic, a user would choose the correct settings for Serial Port Baud
Rate, Serial Port Flow Control, Iterations; and Repeat Alert Video Display. There is also a checkbox to
toggle the Throttle down serial port write speed from Enabled to Disabled.

4.7.2 USB Serial 1 through 4
The USB Serial sub-pages have the same organization as the Main Serial port page and operate in the same
way. Each page corresponds to a different physical serial port.
These ports are supported using the Serial Gear CS-42042 USB to 4 Port RS232 Adapter. Other adapters may
work, but they must be based on the FTDI chipset. As with the Main Serial Port, make sure that the proper cable
54 Digital Alert Systems: DASDEC User Manual
is used for the external CG hardware.
The USB serial ports offer a few different choices for CG's from compared to the Main serial port.
CG protocols are: Off; Monroe R194 CG; CEMS-0500/1000; Standard TFT; Chyron CODI; VDS; Sage Generic
CG; Sage News Room; XBOB; XBOB4; CG BETABRITE LED Sign; Monroe Envoy; BDI GPM – 300 Matrix
Switcher. The SAGE Newsroom protocol is only available on the USB serial ports. The Monroe Envo y protocol is
NOT available on the USB serial ports. The TFT standard protocol is available, but only one instance of the
protocol will actually be allowed to control audio play-out on the DASDEC II. The first instance configured on
Main or USB ports 1-4 would be granted the privilege of running audio.
Setup > Video/CG > USB Serial 1 web page
As with the Main serial port, a status box is also displayed above the CG radio button selector to inform of the
status of the specific USB serial port. If the port is available (the USB expansion unit is installed) on the DASDEC

output port on the back of the DASDEC II.
NOTE: In current software, running the NTSC video details generator will slow down the
start of every alert by a few seconds as the video system is initialized from a VGA
console state to a video output state. Depending on the required timing of your on-air
system, this can be objectionable. Only enable DASDEC II NTSC video details output if it
is needed.

4.8 Setup > Decoder: Setup Decoder Forwarding Options
A standard DASDEC II will run two EAS decoder channels from the Main audio device and two from the Auxiliary Audio
device. It will decode EAS out of the box, once the Master license key is valid. However, a variety of useful options can be
configured to tune the decoder for operation in a specific system within a specific geographic region. All decoder
60 Digital Alert Systems: DASDEC User Manual
configuration options can be accessed through the Setup > Decoder sub-pages.
The Setup Decoder Forwarding Options page has four tabbed sub-pages: Forwarding, Local Access Forwarding,
Demo Decode/Forwarding and Other.
A Decoder only DASDEC II will present a fifth tabbed page, Required Tests. This page requires a FIPS location code for
the geographical location of the DASDEC II. The location code will be used for the One-Button Weekly Test. The interface
also supports configuring random Weekly Test generation. See Chapter 4.9.2 Setup > Encoder > Required Tests for
information on the random Weekly Test interface.
Due to the need for immediate action when setting forwarding options, the Setup Decoder pages do NOT have an
button. Changes to check boxes, selection boxes, and clicking buttons on these pages are immediate.
NOTE: Some browsers will not accept the text edit change until the mouse is clicked
outside of the field entry box. Other browsers simply will accept the change when the
Enter key is touched. You may wish to review Chapter 4.3.4.2 How to Make Changes
and Update.
4.8.1 Forwarding: Decoder Forwarding Configuration
Setup > Decoder > Forwarding header screenshot
The Decoder Forwarding Configuration sub-page is used to configure EAS alert forwarding. Forwarding is
when a decoded EAS is relayed out an audio output of the DASDEC II, presumably into a broadcast audio
signal. Forwarding can be automatic or manual. Forwarding can be set so that all alerts to any FIPS area are
forwarded, or it can be highly constrained so that only a select few EAS codes to specific FIPS areas are
forwarded. Use this page to configure station identity settings and to select how EAS alerts are forwarded. To
select the actual audio output port(s) for forwarded alerts, use a different Web Interface page. See Setup >
Audio > Decoder Audio. Active and expired Forwarded alert events can be examined in detail on the Decoder
> Forwarded Alerts event display page.
There are seven main configuration controls on this page:
1. Local Forwarding controls
2. Forwarding Se rial Protocol
3. Auto or Manual Forwarding Operation
4. Pending Alert Acknowledgment

2. Forwarding Serial Protocol
This hyperlink displays the current serial protocol(s) selected during forwarding. Click the link to go to
the Setup > Video/CG > Main Serial CG Options page to review and/or change the serial protocol(s).
3. Configure Auto or Manual Forwarding Operation
One of the essential decisions that an EAS participant must make is whether to run an EAS decoder in
Auto-forwarding mode or in Manual forwarding mode. This section of options provides the controls over
these two basic options.
The text box on the left side of this section will indicate the current forwarding state. It will display either
"Auto-Forward Mode is Enabled" or "Manual Forward Mode is Enabled." The same information is also
prominently displayed on the Decoder > Incoming Alerts pages. To set the Auto-Forward Mode or the
Manual Forward Mode look to the checkbox to on the right side of this section.
Auto-Forward Mode checkbox: Check (enable) the first toggle box on the right side of this section to
select Alert Auto-Forwarding. Uncheck to select Manual Alert Forwarding. The toggle box will display a
standard label that says if Auto-Forward Mode is Enabled or Disabled and which mode is currently
selected.
When Manual forwarding is set, a user of the DASDEC II must use the Web Interface or use GPI input
contact closures to actively forward any unforwarded alerts from the Decoder > Incoming/Decoded
Alerts Active Decoded list display.
During Auto-Forward mode, the DASDEC II forwards alerts without review or intervention provided they
pass the currently configured Auto-Forwarding criteria.
NOTE: Emergency National Activation (EAN) and Termination (EAT) alerts always
forward automatically.
Digital Alert Systems: DASDEC User Manual

Plus Package License version features
Manual Forward Control – Plus Package licensing enables the user configurable option of
applying the Auto-Forward EAS and FIPS code filters to the pending manual alerts. This feature
allows an extra measure of protection against accidental forwarding. When this option is used,
pending alerts that DO NOT pass the Auto-Forward filter criteria will be blocked from Manual
Forwarding by not displaying the Manual Forward button. Instead, such alerts state that they are
blocked and provide a quick link back to the Setup > Decoder > Forwarding interface. Following
the link back to the Manual Forward control interface allows the control mode to be changed at will
in case it is too restrictive.
There are three levels of control:
1. Off
2. Apply the Auto-Forwarding criteria to just the manual alert forwarding buttons.
3. Apply the Auto-Forwarding criteria to both manual alert forwarding buttons and the GPI input
forwarding actions.
Setup > Decoder > Forwarding, middle section of web page, showing Forward Mode Timers
All licensed versions feature two Forward Mode Timers that can be enabled independently to
automatically switch the DASDEC II between Manual and Automatic Forwarding modes. The timers can
be set to run on a daily basis, or just on weekends or weekdays. Each timer provides a time setting for
enabling Auto-Forwarding and later disabling Auto-Forwarding. Active timers override the toggle for
setting Auto/Manual Forward Mode. The timers allow a station to schedule auto-forwarding when
unmanned and manual forwarding at other times. For both timers, the start time and the stop time fields
need to be modified by the system administrator to configure when the DASDEC II will go into AutoForward mode and it will go back to Manual mode. In the screen shot above, Auto-Forward Mode is
active from 11PM to Noon on Weekdays and all day on Saturday and Sunday.
4. Configure Pending Alert Acknowledgment
When an EAS alert is decoded during Manual forward mode, while active, it causes the red front panel
status light to flash until the alert is acknowledged. Alerts can be acknowledged from the Decoder >
Decoded Alerts page or by pressing the front panel button. In addition, some configuration options are
associated with alert acknowledgment.
Plus Package License version features:
Pending Manual Forward Acknowledge Announcement
Each type of alert category can be configured to play-out an audio announcement on the front panel
speaker during the time the alert is manually pending forward and before it has been acknowledged.
Use the provided selectors to control audio announcement for each alert severity categor y.

Setup > Decoder > Forwarding web page, Configure Pending Alert Acknowledgment
5. Configure Duplicate EAS Alert Handling for Decoder Auto-Forwarding
If an incoming EAS alert is determined to be an exact duplicate of a previously decoded alert, it is
completely discarded and a message is logged in the operation log. However, EAS alerts that are
duplicates except for Station ID or ORG code are stored as a decoded alert and can be optionally autoforwarded or held. Use the selector to choose the setting to control manual or auto-forwarding for these
alerts.
The Configure Update Policy for Active EAS Alerts option, allows you to expire an active alert when
a new alert is decoded and updates the previous alert. When enabled, you can choose what
requirements the new alert must have to expire the previous active alert.
Setup > Decoder > Forwarding Web Page, Configuring Handling of Duplicate Alerts
The following is an example of this situation: Two local radio stations are being monitored; both send
out a Monthly test for the same FIPS codes, and with the same start time and duration, but the stations
have changed the station ID. The alerts arrive several minutes apart. The DASDEC II has been set to
auto-forward Monthly tests to the given FIPS codes. The first decoded Monthly test is forwarded
automatically. The user has configured the duplicate alert handling to NOT auto-forward duplicate alerts
that differ in Station ID or ORG code. The second alert is decoded, but is held for manual forward.
6. Configure EAS code filters for Decoder Auto-Forwarding
Allow All EAS Codes. Use the toggle box to select ALL EAS codes or specific EAS codes to be
decoded and forwarded. When the toggle is checked, all EAS codes are allowed to auto-forward.
Choose from All EAS Codes:
This option is only available when specific EAS Code Forwarding is enabled. If so, select a set of EAS

codes that will auto-forward. Then click to the right of the list of codes. All codes selected for
auto-forwarding will appear in the Current Decoder Auto-Forwarded EAS Codes field to the right.
OR
Add Emergencies, warnings, watches, tests, advisories.
These buttons provide a convenient way to add an entire group of related EAS codes for autoforwarding.
Remove Selected
To remove codes from the auto-forward list, select each EAS code line in the Current Decoder Auto-
Forwarded EAS Codes field and click .
Setup > Decoder Web Page, EAS Codes Type Auto-forwarding
7. Configure FIPS code filters for Decoder Auto-Forwarding
The FIPS configuration section is to set the location code for the DASDEC II. A FIPS code is a unique 6
digit code that covers every State or Territory in the United States, as well as every Count y or County
Equivalent area in the U.S. The FIPS ID is used for Required Weekly Tests for a decoder-only DASDEC
II.
Allow All FIPS Codes. Use the toggle box to select ALL FIPS codes or specific FIPS codes to be autoforwarded. When the toggle is checked, alerts with any FIPS codes are allowed to auto-forward. When
specific FIPS code auto-forwarding is enabled, selection options are presented to create a list FIPS
codes used for auto-forwarding.
FIPS Subdivision, State, and one or more Counties.
This option is only displayed when Specific FIPS Code Forwarding is enabled. Nine subdivisions for
each main FIPS region can be set. The State ID has a pop-down menu to select the State or territory.
County ID has a scrollable selection box to allow one or more County (or County equivalent area) to be
selected for addition to the Auto-Forwarded FIPS list.

forwarding will appear in the Current Decoder Auto-Forwarded FIPS field to the right.
NOTE: When choosing the FIPS codes that you would like to filter, be sure to choose the entire
state FIPS code. This will not send you alerts for every county, but rather it will filter in alerts that
apply to the whole state. For example: New York (036000) in the previous screenshot.

4.8.1.1 Forwarding: Multistation Decoder Forwarding Configuration
Multistation operation leverages the flexibility of the DASDEC II platform to provide EAS operation for
up to five collocated broadcast channels or stations from a single DASDEC II. When Multistation mode
is licensed, the Decoder Forwarding Configuration sub-page is used to configure both system wide
base station forwarding options and for single station option bindings that control individual station
forwarding.
The base station configuration is simply the sum total of the DASDEC II options that enable system
wide control over video character generators (CGs), GPIO relay outputs, audio output por ts, and
network alert connections. When the various DASDEC II Setup web pages are configured you are
creating the base station configuration. DASDEC IIs without the multistation mode only use the base
station configuration. When the Base Station Info interface is edited on the Setup > Decoder >
Forwarding web page, you are configuring the decoded alert forwarding optio ns for the base station.
See the screen shot.
Digital Alert Systems: DASDEC User Manual
67
Setup > Decoder > Forwarding page showing Base Stat ion options
The main purpose of multistation mode is to enable targeted EAS alert origination/forwarding to specific
collocated stations.
IMPORTANT NOTE: This does not lessen the importance of base station forwarding.
Correct base station forwarding is critically important in multistation mode. It is used for
National Alerts (EAN and EAT) and for selected high priority alerts requiring quick
propagation to the public. In both cases simultaneous alert broadcast must occur on the
entire set of DASDEC II controlled stations. Make sure the DASDEC II will correctly
broadcast an EAS to ALL stations with a single alert broadcast while in
multistation mode.
68 Digital Alert Systems: DASDEC User Manual
Correct station configuration allows one DASDEC II to propagate (during alert origination or forwarding)
EAS alerts sequentially to any one of the set of collocated stations (or broadcast channels). During
setup, this is achieved by choosing an exact subset of the base station DASDEC II hardware
connections for each individual station (or channel). The choices are made within a station configuration
interface on the Setup > Decoder > Forwarding web page. The resulting station interface configuration
permits an EAS alert to play on the broadcast hardware for a specific station channel (or channels). In
this way a specific video CG can host an alert text crawl and a specific broadcast program audio path
(tied to the video crawl) can have EAS alert audio inserted on demand. As alerts are played in
sequence this way, the proper audio/video hardware is controlled from the DASDEC II to achieve alert
play-out on a single chosen station.
Setup > Decoder > Forwarding page showing an enabled station name Station 1
Digital Alert Systems: DASDEC User Manual
69
The screen shot above shows an example of a station configuration interface from the Setup >
Decoder > Forwarding web page.
NOTE: Many of the settings on the page also apply to alert Origination. If so, the label of
the control will state that the setting applies to both Orig/Fwrd.
Most of the options for a station can be thought of as providing an override action when compared to
the same option used or available during base station operation. For instance, the base station has a
control point to determine if the NTSC video details page is displayed during alert play-out . Each station
provides its own control for whether or not video details are used. Serial port operation provides another
useful example. The base station defines a set of serial ports that are used during alert play-out. Each
station interface must be configured to select which of the available base station serial ports are be
used for the station during alert play-out.
Here are the interface options for the page.
1. Select Station Configuration Interface
To edit station settings, use the pull down menu Select Station Configuration Interface to
select any station other than Base Station Info. This will display a special set of selection
options for the station.
2. Station Configuration Interface Name
You can rename the interface using the Station Configuration Interface Name text field. This
changes the label displayed for the station in the pull-down menu Select Station Configuration
Interface. The name also appears in many other places on the DASDEC II user interface where
station references are made.
3. ENABLE Station Interface
This toggle allows the station to be enabled or disabled at any time. It must be checked (enabled)
for the station to be available for EAS alert play-out.
4. Shortcut link For encoder station origination configuration options Goto: Setup Encoder
This provides a quick shortcut to jump to the same station configuration interface on the Setup >
Encoder > General web page. On that page are presented configuration options that ONLY
apply during alert origination.
5. Forwarding Station ID
This text field determines the EAS station ID used for the station during decoded alert forwarding.
This ID appears in many other places on the DASDEC II user interface where station references
are made. It is encoded into the EAS alert header audio when an alert is forwarded to the station.
This value is used in place of the Base station Forwarding Station ID.
.
NOTE: This value can be different from the Origination Station ID. However, typically
these should be the SAME. In the Forwarding Station ID is edited and becomes different
from the Origination Station ID, the GUI will display a notice of the fact and provide a
shortcut active link to allow quick editing of the Origination Station ID.
6. Video Output upon alert Orig/Fw rd play-out.
This toggle determines if the NTSC full screen details page is used with this station during EAS
play-out.
70 Digital Alert Systems: DASDEC User Manual
7. Text translation uses forwarded station ID...
This toggle determines if the station substitutes the forwarding station ID into the alert text
translation in place of the decoded station ID. When this option is enabled, another toggle optio n
Station Custom Origination (ORG) Code Translation is presented. This allows custom phrase
substitution for the standard translation of the EAS ORG code.
8. Multi-selection Settings
A set of selection box interfaces are presented for choosing station level hard ware control. Most
of these options apply equally during both alert origination and forwarding! The selection
box label will indicate which controls are shared for both alert origination and forwarding.
With these controls, the station can be set to use specific audio outputs, serial ports, GPO relays,
Network GPIO relays, EAS NET clients, streaming Mpeg clients, etc.
NOTE: The selected serial ports and network client interfaces MUST be enabled in the
Base station configuration.
Any changes made to these options do not take effect until the button is
pushed.
9. Station Auto-Forwarding Configuration
Each station can require specific FIPS codes and EAS codes to become active during alert playout. Careful use of this feature allows every station to play a different set of EAS alerts. If the
Base station already has FIPS and EAS auto-forward filters, they are also used for every
individual station.
The screen shot of Station 1 (above) shows a different station compared to the previous screen
shot. Note the different set of options selected (compare serial ports and audio output ports and
GPO relays) between the two stations.
4.8.2 Local Access Forwarding
The Decoder Local Access Forwarding configuration sub-page is used to configure customized forwarding
play-out for decoded CEM (Civil Emergency Message) EAS alerts. This mode allows for custom alert translation
text and repetition control when a CEM alert is auto-forwarded after being decoded from specific decoder
channels and optionally, from a specific EAS source station (as based on decoded station ID). The mode is
enabled using the checkbox Custom Text Translation for CEM (Civil Emergency Message).
Digital Alert Systems: DASDEC User Manual
71
Setup > Decoder > Local Access Forwarding web page
Custom Text Translation for CEM (Civil Emergency Message)
This toggle box controls activation of the local access forwarding feature. When Enabled, as shown in the screen
shot below, local access forwarding is active and can be configured. If a local access CEM alert is decoded, it
will be automatically forwarded (regard less of the decoder forwarding mode).
Local Access Message Play-out Status
The current status of Local Access Forwarding is displayed near the top of the page. When there are no active
local access CEM messages being played, the status displays:
When a CEM alert is forwarded under control of Local Access Forwarding, the status window will display the
DASDEC II ID of the local access message, information about the repetition number of the play-out and when it
will stop. It also provides a large flashing button for manually stopping the alert play-out at any time. While the
message play-out is active, the Setup > Decoder > Local Access Forwarding page will auto-refresh.
72 Digital Alert Systems: DASDEC User Manual
The same Stop button is also available for the active alert displayed under the Decoder > Incoming and
Incoming/Decoded Alerts page.
Decoder > Incoming/decoded alerts
Custom CEM Text Translation This text, if provided, will be the text displayed on the video details page and
sent to CG's and to network protocols (like EAS NET, SCTE18, etc.) when the CEM alert is forwarded. The
screen shot shows the text "Last night's snow storm has closed city offices today'. When a decoded CEM alert is
forwarded, this text will be displayed on the DASDEC II video details page, and will be sent to any serially
connected character generators and network protocols. If no custom text is entered, the standard translation of
the decoded alert is used. After text is entered, click on the Accept Text Translation Changes button to submit
the changed text.
NOTE: Changed text is not used for an in-progress message.
Optional Station ID filter code can be entered in the field below the CEM text box. This will limit action of local
access forwarding to those CEM alerts decoded from the Decoder Local Access Forwarding configuration
sub-page is used to configure custom forwarding play-out for decoded CEM (Civil Emergency Message) EAS
alerts specified source station.
Select Decoder Channels for Local Access CEM Custom Message This selector interface displays all of the
available decoders on the system. Select the set of decoders that will be valid sources for the CEM custom local
access forwarding response. CEM alerts decoded on the unselected decoder channels will not trigger local
access forwarding and will be processed like any other incoming decoded alert.

Setup > Decoder > Custom MSG Forwarding
If the DASDEC does not have any current active custom message alerts there will be a message that
says: No NET access decoded custom messages at this time.
If the DASDEC does have a current active custom message alert, that alert will appear on the right
hand side of this page in red.
If the NET Decode Custom Message Forwarding option is enabled, then more options appear.
Allow message stop from master NET message originator
This option allows the DASDEC that sent a custom message via EAS NET to control when the alert is
stopped on the receiving DASDEC. If this is not enabled, the user would manually have to stop the alert
on the receiving DASDEC (if it is before the alert is done).

4.8.4 Demo Decode/Forwarding
This page allows you to enable the Practice/Demo operation mode. Yo u can configure alert parameters for a
practice and test run of decoding and forwarding. By generating a trial decoded DMO (Demo/Practice Warning)
alert, rather than having to wait until an actual alert is received, you can simulate the behavior of any inc oming
decoded alert on the DASDEC II. The actual alert is generated with a button named Run Demo Decoded Alert
on the Decoder > Incoming/Decoded Alerts page. (See Chapter 6.2 Incoming/Decoded Alerts). Once
generated, all of the forwarding buttons and edit/review options for the active alert are available for operation.
This feature is especially useful for testing Multistation operation.
Pushing the Run Demo Decoded Alert button will insert a decoded demo alert for easily testing forwarding
configuration and options.
IMPORTANT! Forwarding this alert will take it to AIR! BE CAREFUL ! Examine if Auto-Forward

4.9 Setup > Encoder
To run EAS encoding, a DASDEC II must first be configured with a valid Encoder license key. Verify or enter the license
key on the Setup > Server page. See Chapter 4.1.1 Main/License: Server Name & License Key Configuration. Without a
valid license key, the DASDEC II will not show a Setup > Encoder page nor the main Encoder menu tab.
EAS alert encoding is when the digital codes and alert audio tones and message defined by the EAS protocol, are
assembled into a complete audio sequence for play-out over a broadcast medium for which EAS deco ders might be
listening. This process is call origination when the alert is encoded for the first time on an EAS platform.
The DASDEC II makes EAS alert origination very easy. Every action needed to encode and send any kind of EAS alert is
available on a single page of the DASDEC II Web Interface, under the Encoder > Send EAS pages.
But before you use the DASDEC II encoder, there are some configuration tasks that must be done on the Setup Encoder
General Options, on the sub-page General EAS. The tasks are explained in this chapter.
There are three tabbed sub-pages on the Setup > Encoder screen: General
Due to the need for immediate action when setting encoder origination options, the Setup Encoder pages do NOT have

4.9.1 General: Main Encoder Configuration
Setup > Encoder > General
The Main Encoder Configuration sub-page is used to set the basic encoder values such as EAS Origination
code, Origination code custom text substitution, the EAS station ID, and commonly used alert types and FIPS
locations. These basic items are needed for using the EAS encoder for originating any alert.
76 Digital Alert Systems: DASDEC User Manual
1. Basic EAS Encoder Values Setup
The top section on this screen provides controls to set the basic values to construct an EAS alert.
EAS Origination (ORG) Code
The ORG code is a standard part of the EAS audio protocol. It is placed in the EAS alert message when the
encoder originates an EAS alert. The same code is also used for forwarded alerts. Multistation operation
allows this value to be overridden per station definition. This code categorizes the type of organization
sending the EAS. Use the selection menu to choose the EAS Origination code for your system:
Broadcast station or cable system: Choose EAS
Civil authorities: Choose CIV
National Weather Service: Choose WXR
Primary Entry Point System: Choose PEP
Custom text for origination (ORG) code string: Default is disabled. The origination codes are given a
standard text translation when an encoded EAS alert is sent to a video display. When an EAS origination
Code is used, the alert text will start with the phrase "A Broadcast or Cable System has issued". Checking
the Custom Text option allows a custom translation to be used instead.
In the screen shot below Custom Text is enabled. When enabled, a text entry box is displayed in which you
can enter the organization name issuing the alert for Custom Origination (ORG) Code Translation. In the
screen shot, the phrase, "The Digital Alert Systems DASDEC II,” has been entered as the custom text. Thus
EAS translation text will use this phrase instead of the generic "A Broadcast or Cable System"; the phrase
`HAS ISSUED` follows the custom organization name in the alert translation.
Setup > Encoder, EAS Origination Code, top section of web page

EAS Station ID
Type up to 8 characters in this text field to identify the Station ID for this DASDEC II. This code is included in
all originated alerts, both manually forwarded and automatically for warded alerts.
NOTE: Encoder Station ID can be programmed differently from Forwarding Station
ID, although usually they should be the same value.
Attention Signal Duration
This control allows setting the duration of the two-tone attention signal from 8 to 25 seconds.
Block Origination and Manual Forwarding during in progress alert announcement
Check to block manual play-out of a new alert while another announcement is in progr ess.
Weekly Test Audio
Default is disabled. This checkbox controls whether the originated Weekly Test (RWT) can be constructed
with an audio message.
Segmented Alert Origination
Default is disabled. This checkbox controls whether the option for segmented alert origination is available on
the Encoder > Send EAS pages. Segmented alert origination is when the alert header and attention signal
are played with a pause for live audio voice dub. A separate button then allows the play-out of audi o files
and EOM. (In EAS, the End of Message (EOM) is signaled by the final three FSK audio bursts.)
TDX controls on Send general EAS page
Check to enable TDX controls.
2. Configure Available EAS Types for Encoder Alert Origination Interfaces
The DASDEC II must be configured for the types of EAS alerts that will be available for selection during alert
origination encoding. This is done by constructing a list of alert types to be held in a common pool. The list is
referred to on the DASDEC II as the "Configured Available Encoder EAS Codes". The list appears on the
Encoder > Send EAS > General EAS screen (See Chapter 6.1.1 General EAS).
Setup > Encoder, Available EAS Types, middle section of web page
Choose from All EAS Codes:
To build or edit the available EAS code pool list, choose one or more EAS code types from the selection
box list and click . Codes selected for encoding will appear in the Configured Available
Encoder EAS Codes box to the right. Be sure to add all common EAS types that will be used when
encoding alerts from this DASDEC II. If you find you are missing a code during encoding, you can edit
the pool list at any time.

Codes selected for encoding appear in the Configured Available Encoder EAS Codes box to the right.
To remove a code from the list, select one or more codes and click .
3. Available Encoder FIPS Codes
This section is labeled Configure Available FIPS Pool for Encoder in the user interface. The DASDEC II
must also be configured for the commonly used FIPS locations that will be immediately available for use
during alert encoding. Just as for the available EAS Codes list, a commonly used list of FIPS locations are to
be constructed from the list of all possible FIPS. The list is referred to on the DASDEC II as the "Available
Encoder FIPS Locations". There are thousands of FIPS location codes, so building this pool of commonly
used FIPS codes saves time during typical alert encoding construction. In the rare event that other FIPS
locations are needed, the pool can be edited at any time.
Choose one or more FIPS location codes using the FIPS Subdivision selector, the State (or territory)
selector and the County (or County Equivalent) selection box. Multiple selections can be made at the same
time from the County selection box. Then click . FIPS locations selected for use in the encoder alert
construction interface will appear in the Configured Available Encoder FIPS Locations field to the right.
Be sure to add all the common FIPS codes that will be used when encoding alerts from this DASDEC II.
Otherwise, while constructing an alert, you may have to return to this screen to add any FIPS codes that are
missing from the Encoder FIPS Pool on the Encode and Send an EAS Alert screen.
To remove a location from the FIPS pool, select one or more lines in the Decoder Auto-Forwarded FIPS
field and click .
All operations are immediate.
Setup > Encoder > General, FIPS Codes, at bottom of web page
When encoding an alert on the screen Encoder > Encode and Send an EAS Alert screen, if you find that a
FIPS location code is missing, there is a link on that screen back to the Setup Encoder > General screen. There
you can amend the FIPS pool.

5. Use custom text fo r Origination code string. This toggle controls if custom phrase substitution
is to be used for the standard translation of the EAS ORG code.
6. Origination Station ID
This text field determines the EAS station ID used for the station during alert origination (as
opposed to alert forwarding). This ID appears in many other places on the DASDEC II user
interface where station references are made. It is encoded into the alert header audio when EAS
is originated on the station. This value is used in place of the Base station Encoder Origination
Station ID.
NOTE: This value can be different from the Forwarding Station ID. However, typically
these should be the SAME. In the Origination Station ID is edited and becomes different
from the Forwarding Station ID, the GUI will display a notice of the fact and provide a
shortcut active link to allow quick editing of the Forwarding Station ID.
7. Multi-selection Settings
One selection box interface is presented for choosing station level audio output ports during
origination. Other station level hardware control options for alert origination are combined with
multistation forwarding setup on the Setup > Decoder > Forwarding web page. A convenient

keys to operate.
One of the benefits of the DASDEC II's inherent network nature is that it can support a variety of methods for network
forwarding/origination of EAS alerts, alert audio/video, and remote control. The DASDEC II supports several network
protocols. The EAS NET protocol provides a variety of flexible methods to send alert notifications and data from a
DASDEC II to a remote host (including another DASDEC II). The EAS NET protocol includes support for multiple DVS168 network clients. Another network EAS protocol supported as a licensed feature on the DASDEC II is DVS-644/SCTE18 alert messaging to cable systems. For video and audio, the DASDEC II can uni-cast or multicast an MPEG2
video/audio details page. This, in conjunction with EAS NET or DVS-644, provides a complete digital solution in one box
for EAS requirements. All of these features, when licensed, appear as tabbed pages under the Setup > Net Alerts.
Most of the Net Alert interfaces can be separately enabled / disabled per feature and per client interface. The standard
Networked GPIO supports FIPS programmable LAN based relay triggering during alerts and al ert states.
If a required network interface is not available, it can be enabled using the License Key M anager interface under Setup >
Server. (See Chapter 4.1 Setup > Server: Setup Server.) You must purchase a license key from Digital Alert Systems,
enter the key into the appropriate License Key Manager field, and enable the protocol by restarting the server.

All of the Setup > Network Alert Protocol Options pages use an Button for submitting option changes.
Multistation mode note: When DASDEC II multistation mode is enabled, the Net alert client interfaces used per station
are selectable. Thus, a station can choose to NOT use an enabled Net Alert interface. The station assignment options do
not allow reprogramming of a Net Alert interface, just its inclusion. Also, the specific included Net Alert interface MUST be
enabled for the station to be able to trigger its action. This allows specific Net Alert interfaces to be assigned to different
stations and thereby trigger a Net Alert action only when a specific station is active. Configure per station used Net Alert
assignments on the proper station interface configuration page under Setup > Decoder > Forwarding.

from the One-NetSE to the DVS-168 client, and a control message is sent that describes the alert. The
Operation Log will log each of these actions and their success or failure.
4.10.2 EAS NET
There are three sections on the EAS NET sub-page to configure: EAS NET Decoding, Web audio streaming,
EAS NET Clients.
1. Configure EAS NET Decoding
EAS Net Decoding is included with the EAS NET license key.
Discussion: EAS NET Basic Operation
EAS NET operates by sending optional audio, optional text translations, and an EAS event notification file
from a DASDEC II to a remote device over a LAN or WAN. There are some differences depending upon the
chosen EAS NET protocol. SSH STDIN Only does not offer sending of digital audio WAV files or text
translations. DVS168, being a legacy protocol, does not send the same type of event notification data as the
other protocols. For everything but DVS168, the remote host/server device is sent an event text file or ASCII
data sequence that contains a set of key=value style data lines describing the EAS alert. For every protocol
but SSH STDIN Only and DVS168, the text event file by default is copied into the remote host file
EAS_NET_ALERT under the remote user home directory. This filename and path can be overridden when
configuring the client schema file. A standard set of information fields is sent in the text file, but the actual
names of the keys can be custom edited per client according to a programmable schema. Each clie nt can
be set to use the Default schema or can use a custom edited schema. The DASDEC II EAS NET client
interface provides a schema editor to create specialized schemas.
There is only one toggle button to enable EAS NET decode. Check the toggle labele d "EAS_NET decode
from remote EAS NET sending devices". The DASDE C II will then be able to receive alerts sent via EAS
NET send from a properly configured remote DASDEC II. EAS NET decoded alerts are clearly labeled in the
Decoder > Decoded Alerts status page as being received from input channel EASNET. The alert event
files are stored in a separate disk storage area from audio decoded alerts. Other than those differences,

EAS NET decoded alerts are handled the same as alerts decoded from the audio inputs. Click the
button to save changes.
Setup > Net Alerts > EAS NET Configure EAS Decoding
2. E AS NET Web audio streaming
Discussion: EAS Net Client Web audio Streaming is included with the EAS NET license. This provides a
convenient way to stream live alert audio over a network. This is used primarily to provide live EAN/EA T audio
from EAS NET send to an EAS NET client device (including another DASDEC II). The stream is not an MPEG
transport stream. It is an http audio stream. Remote clients must actively load the URL for the stream in order
to play it. This can be done via most modern media players. A DASDEC II with EAS NET decode will
automatically use this audio stream as a live input for EAS audio as needed. Refer to the screen shot below.
EAS_NET Web (HTTP) Alert Audio streaming during alerts.
Enable this toggle to generate live web streamed audio during alerts. The default values of the options are
designed to work for EAN/EAT.
Audio Streaming on all alert types
This checkbox controls audio streaming for National Alerts (EAN/EAT) or all alert types. For testing
purposes, the toggle "Audio streaming on all alert types
have audio streaming. Make sure to use this button to test live audio for any remote DASDEC II EAS
NET decoder.
Audio Stream Format
You can select either OGG/Vorbis or MPEG Layer 3 (MP3) audio. For audio to a remote DASDEC II
EAS NET decoder, use OGG.
Audio Output Sample Rate Pull-down menu
The correct value for this depends upon the destination. For audio to a remote DASDEC II EAS NET
decoder, use the output sample rate selected on the remote DASDEC II. Choices are 16000, 32000,
44100, and 48000 samples/sec.
Pre-Alert audio/alert header/attention inclusion at start of audio stream.
Pre-Alert EOM Audio Streaming
These two toggle options are included for control of the total content of the alert audio that is streamed.
For purposes of this interface, alert audio consists of three parts: (1) Pre-Alert audio/EAS Alert FSK
header/Alert Attention signal, (2) Alert audio voice message, and (3) Alert FSK EOM audio. No matter
the choices, the second part, alert audio voice message, if it exists, is always streamed. Any
" can be enabled to allow all alert types to

combination of these options will work when streaming to a remote DASDEC II EAS NET decoder. The
default is to not stream the header or EOM sequence, just the audio voice message. Use the options as
required by the specific application on a remote server.
To review, the options allow the inclusion/exclusion of:
1. Pre-Alert audio/EAS Alert FSK header/Alert Attention signal
2. EAS alert FSK EOM.
Delay time before stream start; Starting silence duration; Ending silence duration: This option
allows streaming to be delayed by the duration of the alert header. Three numeric text fields allow entry
of three additional audio delay components. Each delay is in seconds and applies to a specific location
during the audio stream. Use as needed for the specific application.
Setup > Net Alerts > EAS NET Configure EAS Web audio streaming
3. Configure EAS NET Clients
Two toggles are displayed for enabling EAS NET during alert forwarding and origination.
Alert Forwarding to EAS_NET devices
This toggle enables EAS NET send processing during alert forwarding. It can be enabled / disabled at any
time.
Encoder Originated Alerts Sent to EAS_NET devices
This toggle enables EAS NET send processing during alert origination. It can be enabled / disabled at any
time.
Decoded Alerts Can be sent to EAS_NET devices
This toggle enables EAS_NET send processing during alert decoding. Decoded alerts can be sent to
another EAS_NET device without forwarding and putting it on the air.
NOTE: At least one of these toggles must be enabled to allow editing of EAS NET clients. In
the screen shot below
both toggles are enabled.
Digital Alert Systems: DASDEC User Manual
89
Setup > Net Alerts > EAS NET Configure EAS NET Clients
Configure EAS_NET Client Connection
Once enabled, you can create configurations for up to 8 EAS NET clients. Each client can be independently
enabled and disabled, allowing an easy way to stop or restart a client for a specific region.
If no client configurations exist, or if you want a new one and less than 8 clients exist, click the
button to create a new interface configuration.
To edit an existing client interface, select the named client from the pull-down menu Select EAS_NET client
and edit the fields provided in the table underneath.
To delete a client configuration, select the client and click on Client
Interface.
To duplicate an existing client interface (a different name will be automatically generated; less than 8 clients
must exist), select the button. This is the best way to create new
client interfaces that are mostly the same as an existing one except for the IP address.
Careful! EAS NET client configuration addition, duplication, and deletion is immediate and
cannot be canceled.
Discussion: The screen shot below demonstrates an example client configuration. The controls are
described below. The example shows an EAS NET client interface configured to use Secure Co py to send
the alert information and audio files to a remote DASDEC II host. This DASDEC II would need EAS NET
Decode enabled to receive the alert.
During alert processing, the Operation Log will log the success or failure of the EAS NET
forwarding/origination action per client.
NOTE: Every client configuration is used for whichever action of alert forwarding and alert
origination is currently enabled by the toggles described above.
EAS NET uses a flexible set of LAN communication protocols to send EAS data to a remote device.
Generally, the remote device needs to have running software that understands EAS NET files and data
formats in order for anything useful to be triggered by an EAS NET event. All EAS NET protocols will send
an alert event data notification file or ASCII data string from the DASDEC II to the EAS NET remote server
host. Most protocols also allow for sending separate data files (like audio WAV files).
Various information fields must be configured to identify and correctly communicate to the EAS NET remote
client. Common to all are the following:
Client Interface Name - This text box allows the client interface to be given a descriptive name. These
names appear in the selection list.
Client Enable/Disable - This toggle provides a quick method for enabling and disabling the EAS NET
client.
Remote EAS NET Host IP Address - The field displays the IP address of the remote EAS NET host
where the EAS NET event info is sent.
EAS NET Event Transfer Protocol - Displays the Event Transfer protocol. This is simply the LAN
communication method used to send the alert event data. Depending upon the Event transfer protocol,
other configuration fields are necessary or optional. Some protocols require passwords; others use
90 Digital Alert Systems: DASDEC User Manual
encryption keys. Most also provide for optional data file connections.
The event transfer protocol options are:
1. Secure Copy (SCP) – Uses the Secure Shell (SSH) network protocol for both the data file transfers and
event file transfer. No passwords are needed. For all of the Secure Shell protocols (1.3), passwords are
not used. Instead, the DASDEC II public ssh key id (under /root/.ssh/id_dsa.pub and also displayed at the
bottom of the Server > Status > Network page) must be added into the remote host's authorized ssh
keys list. The keys provide for encrypted data transfer and for secure authentication without a password.
2. Secure Shell STDIN Only (SSH) – Uses the Secure Shell (SSH) network protocol for the event file
transfer. No data files can be sent. This protocol requires that the receiving device read the EAS NET
event file from Standard input from within the shell script. In such a configuration, SCP and SSH login to
the EAS NET user will not present to the remote platform shell.
3. Secure Shell STDIN & Copy (SSH with SCP) – This is a variation on protocol #2 above. The event file is
sent as in #2. But the Web interface will display a field to enter a second user account for sending data
files to the remote host. The Secure Shell (SSH) network protocol is used for both transfers.
4. File Transfer Protocol (FTP) – Uses the File Transfer Protocol (FTP) network protocol for both the data
file transfers and event file transfer. A password is required. FTP does not encrypt or secure passwords
during transmission. The password is sent in clear text to the remote host FTP demon. If security is an
issue, do not use or design an FTP based EAS NET scheme. Some FTP daemons refuse passive port
connections. Use the provided checkbox to enable a non-passive connection if needed.
5. TCP event notification – Uses a TCP socket from the DASDEC II to the remote host to send the alert
event file. For sending the optional data files, one of FTP or SSH SCP network protocols can be selected.
A valid user account on the remote host must be entered. The information described above for passwords
and keys apply depending upon the chosen data protocol.
6. DVS168/EARS – This is a special case of EAS NET. A TCP socket is used to communicate an event
notification, while FTP is used to send data files.
7. Legacy Mediaroom – This is a special protocol bundled under EAS NET when the Microsoft©
Mediaroom
8. Mediaroom2 – This is a special protocol bundled under EAS NET when the Microsoft© Mediaroom
option is licensed. This is in accordance with the Mediaroom 2.0 software.
9. MINERVA – This is a special protocol bundled under EAS NET when the Minerva option is licensed. A
TCP socket is used to communicate an EAS event notification as per the Minerva protocol.
10. WideOrbit – This is a special protocol bundled under EAS NET when the EAS NET Automation option is
licensed.
11. RCS Nexgen – This is a special protocol bundled under EAS NET when the EAS NET Automation option
is licensed.
Remote EAS NET Host Port - The field displays the port on the remote EAS NET host where the EAS
NET event info is sent.
EAS NET User - Displays the user account name on the remote device. Files sent to the remote host
will by default be copied relative to this account home d irectory.
Current Schema
The schema determines key names of the information fields sent to the EAS NET client's remote host. It
also determines file names and paths for any files sent to the remote host. The schema can be edited
by clicking on the Edit/Review Schema button.

Other possible EAS NET Client Configuration Options
Not all of these options will appear for every EAS NET transfer protocol.
Client sends EAS NET alert info during alert play-out
When this option is enabled (checked) the EAS NET alert info is sent out prior to alert play-out. EAS
NET prior send is only needed with EAS NET compatible equipment that depends upon GPI controlled
delayed alert play-out.
SSH Public Encryption Key
The SSH based protocols provide this link to the display of the DASDEC II public key. This must be
copied to remote host's authorization file.
Composite Audio File Send
When enabled (checked) a composite WAV file of the entire EAS audio track will be sent as a separate
file to the EAS NET client's remote host. The file name and path on the remote host are determined by
the schema.
EAS Audio File send
When enabled (checked) the individual audio sections of the EAS alert will be sent as separate files to
the EAS NET client's remote host. The file names and path on the remote host are determined by the
schema.
Translation File Send
When enabled (checked) the EAS text Translation will be sent as a separate file to the EAS NET client's
remote host. The file name and path on the remote host are determined by the schema.
Translation File Newline Control
When enabled (checked) the EAS text Translation has all newline characters removed. When disabl ed,
the EAS text Translation includes newline characters.
Video Start Delay Factor (0-10 seconds)
When set to a non-zero value, this adds delay time to the video start time reported in the EAS NET
event file. This can be useful to handle latency between the DASDEC II and the EAS NET remote host.
Duration Extension Time (seconds)
This allows extra time to be added to the internally calculated duration time in the EAS NET event file.
Alert Duration == Audio Duration + Extension Time
All FIPS codes trigger
If enabled, all alert FIPS codes will trigger the EAS NET client interface. In the next screen shot this option is
disabled. Set the checkbox to enable/disable FIPS code filtered trigger control. If disabled, then the alert
FIPS codes are filtered for at least one specific match as a way to control whether or not EAS NET is
triggered. Alerts for specific FIPS areas can be filtered as a way to control whether or not EAS NET is
triggered. If All FIPS is disabled, select FIPS codes from the provided Encoder FIPS pool or the Forwarding
FIPS pool lists and add to the client FIPS list. If any of these FIPS are included in the incoming active
forwarded/originated alert, the alert will be sent using the EAS NET client. With careful use of this feature,
and with multiple clients, one DASDEC II can serve many different cable regions at the same time.

Discussion: Since EAS NET is used in conjunction with third-party management software (on the remote
host), typically, configuration details will depend upon the exact third-party solution. Often instructions will be
provided by this party. Configure the EAS NET client interface as required.
DVS168/EARS devices
DVS168/EARS can be selected as an option on the EAS NET Event Transfer Protocol selector. See the
screen shot below. Like the other EAS NET protocols, the EAS NET remote host IP address and port must
be entered. This would be the address and port of the DVS168/EARS server. Standard DVS168 uses FTP
to send data files, so an EAS NET FTP user and password value must also be entered for a standard client
configuration. However, there is an option to disable the FTP send. This is for servers that do not support
handling digital file data but can be alerted by the DVS168 event protocol. If this option is checked the FTP
user and password values are not displayed or needed since the audio and video files will not be sent.
