Digital Alert Systems Audio Management System

Installation / Operation & Integration

Introduction

The Digital Alert Systems (DAS) - Audio Management System (AMS) –

is designed as a simple solution for the “Twenty-First Century

Communications and Video Accessibility Act of 2010”1 (or simply

21CVAA) compliance, which requires television stations to provide audio

description in their Secondary Audio Program (SAP) channel to aurally

represent any “emergency information” appearing on the main channel.

This means any crawl or text displays on the main channel such as

weather alerts, emergency conditions, etc. – separate of actual

newscasts or EAS alerts – must be “voiced” on the SAP channel. In

addition, an “attention” signal or tone must be inserted on the main

channel to alert or indicate to viewer’s emergency audio is available on

the secondary channel.

The AMS is a two-part system consisting of a DAS Audio Message Controller (AMC) and its companion MultiPlayer™ whose

front panels are shown in Figure 2 and Figure 3 respectively; together provide proper message audio for both Main and SAP

audio streams. The DAS AMS is designed to aggregate information from a variety of sources, convert the text information to

audio using a high-quality Text-To-Speech (TTS) convertor, prepare it for playback on the different audio channels, then provide

audio and triggering signals on all configured channels under a single user interface.

Figure 2 Digital Alert Systems Audio Message Controller - Part 1 of the Audio Management System

Figure 3 Digital Alert Systems MultiPlayer™ - Part 2 of the Audio Management System

How it works

Both the Audio Message Controller and MultiPlayer are linked via a standard Ethernet (TCP/IP) network, which provides a

properly credentialed operator system configuration and control using any standard web-browser. Once configured, the AMC

gathers emergency information from a variety of sources by monitoring network file locations or by other systems transferring

files to it then applying input filters to retrieve the appropriate information for text-to-speech conversion and subsequent queuing

and playout.

Besides actively monitoring data sources, an operator may load a pre-produced audio file, enter message text directly, or cut

and paste message text for automatic Text-To-Speech conversion. The AMC then handoffs the .WAV file, or the TTS audio file,

to the MultiPlayer readying it for playback.

Revision 3.0 Page 4 of 31

Once an audio message is loaded (queued) in the AMS, the playback can be triggered in one of three ways;

1. Automatically - immediately after the audio message is loaded

2. By GPI trigger

3. By the operator clicking the "Play" button on the user interface

There are three Audio Types defined by the AMC and managed by the MultiPlayer

Audio Type

Action

Main

Plays attention tone only

SAP

(Secondary Audio Program)

Plays attention tone immediately followed by the alert text audio repeated the

number of times defined in AMC. The attention tone is not repeated.

Preview

Provides an audio output for an operator to listen to the queued event without

attention tone, or interrupting either audio program streams. Very useful for

evaluating word pronunciations while modifying the TTS lexicon

Table 1 AMS Audio Type definitions

When activated, Main audio plays the preset attention tone then quickly returns to normal programming. The user can upload a

.WAV file of their liking perhaps a two-tone burst or a pre-recorded announcer indicating, “Additional audio information is

available on your secondary audio channel”, or use the default three tone alert programed with the unit.

Simultaneously the SAP (Secondary Audio Program) port is switched in and plays its audio message the two times as the rules

require, or a user defined number of iterations, after which it returns to normal SAP audio.

Installation

Each piece of the AMS it designed to be rack mounted in a standard EIA 19” rack assembly. The location of each unit is best

determined depending on the easiest location for wiring the various audio and video connections.

Configuration Steps

The installation and configuration will cover three major steps;

Step 1. MultiPlayer — Installation and initial configuration

Step 2. AMC — Installation and initial configuration

Step 3. Data Source Configuration

Each of these steps is covered in detail within the following pages. Additional information is also available in the Appendix and on-line at www.digitalalertsystems.com

Digital Alert Systems AMS Installation / Operation & Integration Guide

Revision 3.0 Page 5 of 31

Step 1. MultiPlayer — Installation and initial configuration

The Digital Alert Systems MultiPlayer (model DASMP) is uniquely designed four-channel (designated as Ports 1 thru 4) audio

player and program switcher. The MultiPlayer works in conjunction with the AMC to provide independent audio playout for up to

four discrete channels whose particular operating attributes are defined in the AMC. The four independent ports can be

configured for mono-analog or stereo AES and ports can be “bonded” or grouped together to create multi-channel audio

configurations described below. The MultiPlayer’s flexible design allows it to be configured to use its internal switching or

originate the audio signal(s) for switching or embedding by downstream devices, including independent GPO’s to trigger these

devices. The MultiPlayer features automatic program bypass in the event of power fail thus assuring the program input for any

port is automatically routed to the program output of the same port if there is loss of power or power supply failure.

For clarity the term Audio Signal refers to the physical nature of the signal i.e. (AES) digital audio or analog, while Audio Type

denotes the action that will be applied to the signal during playback.

MultiPlayer - Mounting

The MultiPlayer manages the audio and contact closure wiring; therefore to facilitate ease of wiring it should be placed in close

proximity to audio signal sources and control points. The unit is attached to a 19” EIA equipment rack using the standard

mounting holes on the front panel. Mounting screws are included in the shipping box.

MultiPlayer – AMS Configuration Examples

The Multiplayer features four Ports, each having an independent audio switch, four (4) GPI’s, and two (2) GPO’s. Based on the

required number of audio channels for the application each port may be used and configured in a different manner. Playback

control PLAY/PAUSE/STOP can be independently managed per port, however in the AMS application the incoming data is the

same for all ports and therefore creates the same audio file which is loaded into each channel.

For simplicity, it may be a good idea to wire the station’s Main program audio through Port 1 and the associated SAP channel on

Port 2. This is by no means the only configuration as there are a variety of ways the MultiPlayer and AMC can be configured to

manage different signal and source scenarios.

MultiPlayer - Wiring

MultiPlayer - Audio Connections

Audio connections are made to and from the MultiPlayer for each audio signal through the XLR connections on the ports labeled

1, 2, 3 & 4 as shown Figure 6. The AMS application does not require the Master Port and this port should remain unused.

Figure 6 MultiPlayer rear panel showing connections on Ports 1 -4. Master Port is not used

MultiPlayer ports are configured by selecting one of the standard audio signals then, under the AMC interface, selecting the

audio type. In this manner any port may be used for any audio signal as each port is configured for the audio type; Main, SAP,

or Preview in the AMC configuration. This allows mixing and matching any audio type across the four ports, which is especially

useful for stations with multiple Main and SAP channels.

Each of the MultiPlayer’s audio input/output ports can be configured to handle any one of these audio signals:

MultiPlayer Audio Signals (per port)

Designation Description

AES3

AES digital with input (stereo pair) – locks to incoming AES signal for clock reference (Factory default)

ORIG

AES digital without input (stereo pair) – uses internal reference clock, generates AES silence when not playing

ANALOG

Analog mono – balanced audio input and output

SLAVE

Analog stereo – combination – ties playout with prior port ANALOG channel, creating an analog stereo pair.

Table 2 MultiPlayer supported audio signals and designations

From the factory each port is preset for AES audio signal pass-thru. This may be changed to reflect AES origination or analog

mono as explained in Audio Port Configuration section below.

MultiPlayer - GPI’s & GPO’s

The MultiPlayer features four (4) General Purpose Inputs and two (2) General Purpose outputs per each port. The table and

picture below define the wiring locations and the corresponding labeling in the AMC. These ports match the AMC configuration

settings in the Configure > GPIO menu.

Notes:

1. GPO’s are not grounded, having two connections (Pins 1 and 2).

2. The terminal strip is removable to facilitate ease of wiring.

MultiPlayer - Setting/Modifying IP Address

The MultiPlayer ships with a factory default static IP Address: 192.168.0.220. To match a

station’s network configuration the IP address will most likely need changing which requires

initially logging in to the MultiPlayer at the 192.168.0.220 address to modify IP configuration.

(Additional information on configuring a PC network connection can be found in the Appendix.)

A CAT-5 network crossover cable is shipped with the MultiPlayer to allow direct connection from

a PC network interface to the MultiPlayer network port.

CAUTION: Before directly connecting a PC to the MultiPlayer always verify the cable is a

crossover by referencing the picture in Figure 7. Failure to use a crossover cable may either

cause the interface to not work, and one or both network ports may be damaged.

To assure a stable and steady connection with the AMC, the MultiPlayer should be configured with a static IP address. Consult

the IT department to determine the following information:

Static IP Address

_ _ _ . _ _ _ . _ _ _ . _ _ _

Gateway

_ _ _ . _ _ _ . _ _ _ . _ _ _

Subnet Mask

_ _ _ . _ _ _ . _ _ _ . _ _ _

Use the following steps to modify MultiPlayer IP Address:

1. Power up the MultiPlayer by inserting the AC cord and attaching to 100 – 240 VAC power source

2. While the MultiPlayer is booting (approximately 10 sec) open a web browser on the PC

3. In the address line type 192.168.0.220 and press Enter button. You should be greeted with the MultiPlayer Home page as shown in Figure 8

4. On the left side of the page click the TCP/IP Configuration link. The screen should now display the TCP/IP configuration page as shown in Figure 9

5. Enter the previously obtained information for IP Address, Gateway Address and Subnet Mask in the associated fields

6. Click Save Changes to store the values

7. Click Restart System with New Values will restart the MultiPlayer with

the new values

8. Disconnect the network connection from the PC and plug into the network switch/router

9. In a networked browser enter the new IP address to confirm connection. The MultiPlayer’s home screen should appear

MultiPlayer - Resetting Default IP

If necessary to reset the MultiPlayer to the default IP Address (192.168.0.220), press and hold the RESET button (located in a

recess on the back panel) for 10 seconds.

MultiPlayer - Audio Port Configuration

Once the MultiPlayer’s network configuration is complete the next step is to configure the audio signals to match the wiring

descibed above. The MultiPlayer can support different audio signals per port.

MultiPlayer Audio Signals (per port)

Designation Description

AES3

AES digital with input (stereo pair) – locks to incoming AES signal for clock reference (Factory default)

ORIG

AES digital without input (stereo pair) – uses internal reference clock, generates AES silence when not playing

ANALOG

Analog mono – balanced audio input and output

SLAVE

Analog stereo – combination – ties playout with prior port ANALOG channel, creating an analog stereo pair.

Table 4 MultiPlayer supported audio signals and designations

Type the IP address of the MultiPlayer’s IP address into a

network connected web browser to display the MultiPlayer

home page.

Click Audio Port Configuration text link on the left to

navigate to the Audio Port Configuration page.

In the factory configuration, all channels are set as AES

digital channels. Each port operates independently and is

not bonded to another port.

The current signal type for each port is shown in the text

below Chan x: (where “x” is the associated port number).

To change audio signals use the pull down menus as

shown under Port 1 to the right. Refer to Table 4

MultiPlayer supported audio signals and designations for

more information about each selection.

In the analog mode each port is a single audio channel. to

create a stereo pair, select, Port 1 as “ANALOG” and Port

2 as “SLAVE”. This forms a bonded pair for Left and Right

audio. Similarly setting ports 3 & 4 in the same way

creates a second stereo analog pairing forming a second

bonded pair.

(Note: The “SLAVE” option is only selectable for Ports 2

and 4)

IMPORTANT NOTE: Selections must be made for each Port regardless if they differ with the current settings.

Once a selection has been made for all of the ports, click Save Changes. To ensure all settings have saved, click the Refresh button. If the configuration remains as desired the settings have been properly stored. If not repeat the selection of each port as outlined above.

Step 2. AMC — Installation and Initial Configuration

Figure 11 AMC - Audio Message Controller - Front Panel

Figure 12 AMC - Audio Message Controller - Rear Panel

Mounting

The AMC can be easily mounted in any standard 19” equipment rack. Device location is very flexible as it usually only requires

AC Power and a network connection able to reach the same network as the associated MultiPlayer. If the USB serial ports are

used (rarely) the distance to the serial data source should be taken in account making placement more distance critical.

Wiring

Connect the AMC to the same network as the MultiPlayer. Provide AC power.

Configuring

The AMC is initially configured with both factory default static IP Address at 192.168.0.210 and DHCP client for network

administrators wishing to manage DHCP access to these devices. The media access control address (MAC address) is printed

on the rear panel of the device, so network administrators may assign a specific IP address to the unit through the network

DHCP server. Please contact your network administrator if you have questions regarding your network connections.

AMC Menus

From a web browser type the IP address of the AMC (default is 192.168.0.210) and press Enter. The log in screen as shown in Figure 13 should appear.

If the page does not appear it may require entering the full path http://xxx.xxx.xxx.xxx or the secure version

https://xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx is the AMC’s IP address in order to gain access.

When using https:// a prompt may ask about the security certificate to allow access. Simply respond in the affirmative.

Home Screen - Queue Manager

Digital Alert Systems AMS Installation /Operation & Integration Guide

Revision 3.0 Page 11 of 31

The Alert Queue on the Home screen provides a list of items in the queue, in the order they were received. The fields for each line include the cue number, the file source, the time and date received as well as the first 15 – 20 characters of the contents. For more than one item the display shows a paged list of items allowing simple queue management by viewing and selectively deleting any of the queued items.

Beginning with Version 2.0 the Queue Manager features Replay Mode which automatically recues the same audio if there are no new items in the queue, meaning the last played item will remain playable until a new element arrives. If an item is in Replay Mode the queue counter will display Replay – indicating the system has an item available for playout, even though it has already played, at least once to completion, across all active channels.

1. The Alert Queue title bar indicates the number of items in the queue in the black box. If the Alert Queue is in Replay Mode, the queue counter will display Replay. The blue box number indicates the number of selected items. Clicking the arrow at the right expands and collapses the queue window.

2. Basic fields are: ID, file time/date, file source, and the first 15 to 20 chars of the content. The item at the top of the list is currently loaded and ready for playback. Clicking a line will select that element and turn the background blue. Clicking again will deselect it. Selected item can be deleted by clicking the Clear Selected button. If there are more than 5 or 20 (depending on selection) items in the queue the system will create another page indicated with the information at the bottom of this area. While in Replay Mode, a Clear All command from the User Interface or the new Clear Queue GPI will remove the recued audio and the queue counter displays a “0” (zero).

3. The Cued Text shows displays the full text of the currently cued alert, including if the alert is Replay Mode. Clicking in the box will allow direct entry of new text or editing the existing text. Clicking the Update button will generate a new entry in the queue.

Setting Playback Controls

• AMC Configure > Playout

The System menu set 5 operational parameters; the Play Mode, the number of Play Loops, the Replay Mode, Auto Delete, and the Attention audio.

The Play Mode defines how the system will respond to data inputs. In the Manual mode audio message will be queued in the order receive, but will not play unless a user specifically clicks the Play or Play All buttons on the Home screen. When set for GPI mode, response is governed by a GPI to trigger playback. Under Auto the system will play a message immediately upon conversion without waiting for an operator or GPI trigger. Regardless of the selected mode an operator always has override permissions for playback, pause, or stop (see Home screen).

The Play Loops parameter sets the number of iterations the message audio will play on a SAP configured channel. (Note: as of this writing the 21CVAA rules require message audio be played at least twice after the attention message)

Replay Mode automatically recues the same audio if there are no new items in the queue, meaning the last played item will remain playable until a new audio file arrives. If an item is in Replay Mode the queue counter will display Replay on the Home page – indicating the system has an item available for playout, even though it has already played, at least once to completion, across all active channels. The intent of this feature is to keep the last played Alert audio file in the Alert Queue so it may be played again without recreating the Alert audio file.

To the right of the Replay Mode check box is the Replay After check box along with Minute / Seconds values. Check the Replay After check box to continually repeat the Attention audio and the Alert audio. The Minute and Seconds value represents the amount of time after the Attention/Alert audio sequence is complete before replaying the sequence over again. This process will continue until:

• an operator clicks the Stop All & Return to Program Audio button on the Home page

• a new alert is received into the Alert Queue

• a GPI trigger is received

The Auto Delete check box enables the automatic deletion of alert audio files based on a time value. Hours and Minutes text entry fields will appear once this check box is checked. Set the desired amount of time (between 0-99 hours and 0-59 minutes) before the alert audio files will be removed from the system. (Note: the Attention audio will not be erased when Auto Delete is enabled)

The Attention area shows the audio file currently set and in use. The attention file will play on all Main and SAP configured channels. This file will interrupt the programming on a Main channel. On the SAP channel, the attention file will play first followed by the audio message for the number of times set in Play Loops or when in Replay Mode (with Replay After active). The Attention file can be changed by clicking the Choose File button and select a new attention file.

To accept any changes to this screen, click the Save button.

1. Assign the Play Mode using the pull down menu for Manual, GPI, or Auto

2. The value in Play Loops field indicates the number of times the audio message will play on a SAP configured channel

3. Enable Replay Mode to keep the last played alert audio file in the Alert Queue. Replay After will continually repeat the Attention/Alert audio sequence.

4. Check the Auto Delete check box to enable the automatic deletion of Alert audio files based on time

5. Just right of Attention is the audio file name set as the attention tone. To change click the Choose File and select a new file2 . The new file name will now appear

6. To accept any changes to this menu click the Save button.

For proper playback the attention tone must be a 16KHz sampled 16-bit.WAV, mono format file.

• AMC Configure > Sources

The AMS interfaces with a number of different data sources (see STEP 3 – Data Source Configuration below). Some sources communicate to watch folders in the AMC, while others rely on external watch folders. The Sources tab provides configuration adjustment for external watch folders.

The AMC establishes a File Transfer Protocol (FTP) link with the external folder and then periodically checks the designated files in the folder for changes. If the file contents have changed the AMC will then process the new information.

Initially or, if no external watch folder sources are configured the display starts as shown in Figure 15.

Clicking + Add Sources will open additional window for editing/modifying the links to the external watch folders.

1. In the Type field the pull-down selects an available interface type automatically filling the other fields with standard presets

2. The Name field is used to create a unique designation for the interface and will appear in a list in the left most columns

3. Just right of Attention is the audio file name set

a. IP Address - the network reachable IP

address of the watch folder b. Username - the watch folder ‘s login name c. Password - the watch folder’s login password d. Source Directory - the watch folder’s file

path, where source XML files are

stored/updated. Be sure the pathname is

complete including any “/” characters

4. File Names – The AMC is able to monitor multiple files in a watch folder. Simply list all monitored filenames separated by a space. e.g. “breaking.xml” or “breaking.xml closings.xml”

5. To accept any changes to this menu click the Save button

Sources may be enabled or disabled using the check box alongside the name in the leftmost column. In this way an operator can control access or the specific files/folders the AMC will monitor for source data.

Setting Channels

• AMC Configure > Channels

The Channels menu links the MultiPlayer Port with the audio Type or action desired for that port. Together with MultiPlayer’s Audio Port Configuration, which sets the audio signal, the Channels menu defines the playback manner of each port.

Selecting/de-selecting the box in the Enabled column will turn on or of the respective channel. When updated these changes are reflected on the Home page.

The Name field allows a channel to be labeled with the information entered here being displayed on the Home screen, therefore it is a good idea to use a station’s ID along with the type of channel to better understand the action a user should expect on that channel. For example, entering WQRR-Main for the Main channel, or WQRR-SAP for the secondary audio channel would let a user on the Home page

1. Click Configure on the top menu bar, then the Channels tab. (the default values are preloaded) When updated changes are reflected on the Home screen as indicated in by the boxes.

2. Selecting/de-selecting the box in the Enabled column will turn on or off the respective channel.

3. Enter any descriptive text in the Name text box. Best practice is to enter a station’s call letters.

4. Using the pull-down menu select the Audio Type – either Main or SAP. (defined in Table 1 above.)

5. Click the Save button to save any changes.

Setting Network

• AMC Configure > Network

As previously mentioned, the AMC is factory configured with both a default IP Address at 192.168.0.210 and DHCP client. For network administrators wishing to manage DHCP access the media access control address (MAC address) is printed on the rear panel of the device. With this information a network administrator may assign a specific IP address to the unit from the network DHCP server.

The current network settings will be displayed in the individual fields when this menu is opened. Modifying the IP address and other network parameters will over-ride the current settings.

CAUTION: Improper or incorrect settings may result in no access and restoring the default settings may be the only way to regain access to the unit.

Setting a Static IP Address

1. Using the Configure IPv4 pull-down menu select, Manual. The other fields are now editable (Values shown at right are examples only and may not reflect the required network values)

2. Enter the IP Address, the Subnet Mask, the Gateway (Router) and any DNS Servers. Multiple entries should be separated with a space. (Note: Several features require Internet access making these entries important to overall operation)

3. (Optional): Enter any Search Domains the AMC should look for simple or directed resolution. Not required for standard AMC operation

4. To accept changes, click the Save button. The system will immediately use the new settings, this may require changing the web address or refreshing the page

Using DHCP for IP Addressing

If the AMC found a DHCP server at start up those values would be shown in their respective fields. If there was no server or the unit is switched to Manual the DHCP client shuts off. To use a DHCP server to assign networking values:

1. Select DHCP from the Configure IPv4 pull-down menu. (Values shown at right are examples only and may not reflect the required network, moreover any information displayed without an input box were received from the DHCP server and are non-editable)

2. Click the Save button. The system will immediately use the new settings. This may require changing the web address or refreshing the page..

(Optional):

3. Enter any additional DNS Severs or Search Domains in their respective fields. Multiple entries should be separated with a space

4. Click the Save button Not required for standard AMC operation.

Resetting to default IP

If necessary, please contact the factory for information on resetting the default IP (support@digitalalertsystems.com)

Setting Text-To-Speech Options

• AMC Configure > TTS

This menu is used to select the TTS voices used for text conversions, in addition to adding, deleting or modifying a particular voice’s lexicon. The AMS features the standard “Callie” voice Text-To-Speech (TTS) engine and any future voices available for purchase and inclusion into the system.

The TTS engine uses a lexicon file for special instructions on how to “speak” a word or phrase in a particular way (Click the Options button to view the Lexicon features). For example the word “wind” can be pronounced both as “wīnd“ with a long “I” sound meaning to coil or wrap something, or “w-eh-nd”, as in a High Wind Warning. Also the text abbreviation “T-Storms” may be used as an abbreviation for the word “Thunderstorms”. Adjusting the lexicon can greatly improve the way a TTS system understands and voices these types of words. Along with being able to control individual words, Pitch and Speed parameters allow global adjustments to how the system speaks all text. There are a number of “test” buttons to sample any additions or modifications thus allowing a user to very closely refine how the system will speak any text.

1. The standard TTS voice is “Callie” a female US English voice standard on all AMC’s. Additional

2. The fields for Voice, Language are preset, as well as the licensing fields for the standard voice. These are grayed out and non-editable

3. Clicking the Options button near the bottom will expand the screen to reveal additional settings for controlling the text-to-speech playback

1. The screen displays the lexicon table of uniquely pronounced words or abbreviations. Each item consists of two fields: Literal and Pronunciation where Literal is the exact text of the word or abbreviation being defined, and Pronunciation is a list of "phonemes" which represent how to pronounce (voice) the word. The value in the upper right corner indicates the number of entries in the table. The word “T-Storm” is presented as a commonly used example. When the AMS “sees” the abbreviation it will speak it as “thunderstorm” described by the phoneme list to the right.

2. The Voice section allows for both Pitch and Speech Rate controls for fine-tuning the voice. The default values are “0” for Pitch and “6” for Speech Rate. Adjusting these sliders acts globally affecting the entire speech playback.

3. The Test area lets users create a sample sentence or words to test the settings of the speech engine before committing to the changes. Typing in the text field then clicking the right-facing triangle at the end of the line will create a sample audio file that will play on properly configured browsers. (Note: It can take several seconds to create the example audio playback so be patient)

Digital Alert Systems AMS Installation /Operation & Integration Guide

Revision 3.0 Page 18 of 31

1. To add a new lexicon entry click the Add button and the screen will expand with two text entry boxes for Literal Text and Pronunciation.

2. Type the word or abbreviation in the Literal Text entry field. There is no regard for capitalization, so Wind, WIND, WinD would all be spoken the same.

3. In the Pronunciation field enter the phonemes to create the sounds the TTS engine will use to speak the word. There is a great deal of information available as well as a number of important examples for creating a proper phonemes list by clicking the Help button. (Note: It takes time and practice to properly create the right set of phonemes and incorrect values will cause the system to simply use the default pronunciation for that word)

4. When done click the Add button to save the entries

Scroll down for phoneme examples

1. The lexicon table will be updated and the numeric indication incremented

2. To review or preview the sample highlight the text by hovering over the line then click the triangle “play” button on the right

3. After a few seconds an audio player control will appear at the bottom and the word or abbreviation text will be played through the browsers speakers. The selection can be repeated by clicking the play button on the audio control panel

4. To edit or modify the lexicon entry simply click the line and the entry lines will reappear. Make any changes then click the Save button to save the entries. This must be done each time a change is made in order to properly store the modified values

5. Clicking the play arrow on the lexicon line will create a new audio preview using the changes

6. The Test area can accept a full string of text allowing a user to preview how a word or an entire sentence, or phrase may be voiced, including any changes in Pitch or Speech Rate. (Note: any changes require clicking the play triangle at the end of the text line to create an updated audio preview)

Setting Date & Time

• AMC Configure > Date/Time

The Date/Time functions provide proper time/date stamping of files and logs within the AMS. The system can be run on an internal clock, or synchronized to a Network Time Protocol (NTP) server via the network connection.

1. Selecting the Set Date/Time using Network Time Protocol (NTP) Server check box will activate synchronization with the NTP server defined in the field. The north- america.pool.ntp.org server is one of many available via the Internet.

2. To change NTP servers, enter the address in the associated field. (Note: If the NTP is an Internet name the network settings must have a DNS location for proper address resolution)

• A red indicator

is displayed if the NTP

connection is severed or unreachable.

• An orange indicates the AMC is sync’ing with the selected NTP server. Recognize it may take up to 10 minutes to sync.

• Green means the AMC is connected and synchronized with the selected NTP server.

3. Using the time zone pull-down select the location to properly adjust the time offset for all records and logs. In other words, changing the time zone will reflect in the logged time stamps.

4. To accept any changes click the Save button.

Installing Updates

• AMC Configure > System

The AMC Configure > System page shows several pieces of hardware and software information currently running on the AMC. The system uses a simple Internet based updating mechanism that requires Internet access to the Digital Alert Systems/Monroe Electronics update server. Updates are not “pushed” to the AMC, rather they are only available on “demand” by the Administrator or an admin-level operator. This means an admin-level operator must click the Check for Updates button for the system to contact the update server to see if any updates are available. In addition, there is a Remote Support slider switch, which an admin can activate, allowing linked access to the Digital Alert System customer support network. This feature provides a mechanism for greater detailed support and evaluation, however should only be enabled when requested by DAS technical support.

1. Remote Support slider switch activates linked access to the Digital Alert System customer support network. This feature provides a mechanism for greater detailed support and evaluation, however should only be enabled when requested by DAS technical support.

2. Clicking the Check for Updates button instructs the AMC to check the Digital Alert Systems server for any updates.

1. The current status of each element will be displayed on an Updates pop-up. The currently Installed version and the latest Available version of each part of the system is displayed

2. If any new updates are available the display will indicate so in the tabular form shown at left

3. If all versions are current or to ignore any updates click the Cancel button

4. To update any one or all of the components select the check box to the left of each Package on the associated line, and then click the button.

If the Updates page shows more than one module available, it is generally advised to check them all to assure the OS and Applications remain synchronized. Some features or functions may not operate properly if only a single package is updated.

IMPORTANT: An App update requires a manual browser page ‘refresh’ and an OS update requires a manual reboot after closing the update dialog for changes to take effect.

1. The display will expand to show the download and updating progress as seen in the example on the left

2. Once the download and update is complete the screen will refresh with the latest information.

3. In those cases where a reboot is required it will display the log in screen

Setting General Purpose Inputs and General Purpose Outputs

• AMC Configure > GPIO

The AMS provides a number of General Purpose Inputs and General Purpose Outputs using the GPIO connections on the MultiPlayer (see Table 3 MultiPlayer GPI & GPO connections. Port 1 shown as example - other ports follow same configuration.) Each GPI and GPO features mnemonic area allowing each input or output to be labeled thereby making it easy to identify which device is either sending or receiving the intended signal. These labels and the current state are also shown in the MultiPlayer expanded view on the Home page.

1. Each of the GPI’s and GPO’s can be labeled by editing the Name text field above each of the pull down menus (Values shown at right are examples only and may not reflect the required or desired configuration)

2. Using the pull down menu select the desired action for each of the GPI’s and GPO’s. The actions for each function are described in the tables 6, 7 & 8 below. If there is no action required leave the action in the default states of Ignore for GPI or Disabled for GPO.

3. To accept any changes, click the Save button. To Reset all name and action settings, click the Clear / Reset All button.

Digital Alert Systems AMS Installation /Operation & Integration Guide

Revision 3.0 Page 22 of 31

GPI/O Prioritization

• When an alert is ready to play, any GPO’s designated “Cued” will close prior to play.

• Playout can be started manually (Manual), immediately (Auto), or by GPI according to the Play Mode (which is set

in Configure > Playout).

• The alert remains active until it has played on all configured channels at which point all the GPO’s will open.

• Regardless of playout mode, the operator can always manually control playback with the UI buttons.

• Multichannel GPI control can create ambiguous inputs conditions. For example, if one input has Play All ‘on’ and

another input has Stop All ‘on’, they clearly conflict. In cases where multiple conflicting GPIs are present simultaneously, the AMC use the following prioritization:

Priority

GPI Input

Note

Halt

These commands will work non-exclusively, in other words the system will accept them without priority

Clear Queue

Next All

Continuous Play

0 Delay Play

Disable Channel.

Channel will ignore GPI inputs

Stop Channel

Play/Pause Channel

Play Channel

Pause Channel

Rewind Channel

Stop All

Play/Pause All

Play All

Pause All

Rewind All

Table 5 GPI Prioritization shown in order

• Channel controls take precedence over global controls. In another example, if a Play All is ‘on’ for one input and a Stop Channel is also ‘on’, the Stop Channel takes precedence over the “All” command and that channel will stop

playout.

Other notes

o A channel may be switched off at any point. If anything is playing when it is switched off, that channel will

stop play, pulse any Momentary @ End GPO’s and leave all assigned GPO’s open

o While switched off, the channel will display in gray on the UI. If a channel is switch back on while an alert

is ready, the channel will cue any “Cued” GPO’s and remains in a Stopped state.

o Any time ‘Stop’ is pressed (either the channel or Stop All), any “Cued” GPO’s for the channel(s) will be

closed. In this manner the “Stop All” function has the effect of resetting to the beginning of alert.

o GPO’s now follow each channel independently meaning GPO ‘duration’ will be closed for the specific

channel as long as it’s playing/paused.

o Any GPO’s designated “Momentary” will pulse closed for roughly 200ms, then open again.

Global Commands – Controls all channels

Stop All

Stops playback on all channels, opens any GPO’s and returns to program audio

Play All

Active input causes all channels to Play audio at top of queue

Pause All

Active input high will pause all playing channels. Active GPO’s remain closed. Audio output is silent.

Play/Pause All

Active input causes all channels to Play All, Deactivated will Pause All channels.

Rewind All

Active input will return playback to the beginning of current file, and Pause All.

Next All

Active input will cause playback to jump to next item in queue.

Halt

Active input will disable any input processing or logging.

Clear Queue

Active input will clear all items in the queue. If an item is Auto Recued (counter shows =-1) it will be deleted.

Continuous

Play

When the GPI remains active, all alerts will automatically play. This is similar to Auto Playout Mode.

Delay Play

User definable delay before playing alert. (Delay can be set from 0-99 seconds)
