Cap Decode - Digital Alert Systems DASDEC II User Manual

Two other options unique to the DVS168 protocol are also provided.
1. To send just the EAS alert audio message, instead of the EAS FSK header and EOM audio and
attention audio, use the provided checkbox. Before using this option, it is important to make sure your
local EAS plan allows the FSK audio to be discarded.
2. Alert duration data format. Typically, this is in minutes, but some DVS-168 interpreters have coded this
differently. The selector provides two other interpretations.
The DVS168 protocol does not provide a programmable schema. For DVS168, the data schema is
predefined and the schema selection is not displayed. As with the other EAS NET protocols, the Video Start
Delay time, the Duration Extension time, and FIPS based net alert triggering are all configurable.
When you finish making changes, click
DVS168/EARS operation - When a forwarded/originated EAS alert is to be sent using a DVS-168 EAS NET
client, a TCP socket is temporarily opened from the DASDEC II to the DVS-168 remote host. If this
succeeds, and the alert is a non-national alert (and FTP is enabled), a WAV file of the EAS audio and a text
file of the alert details are FTP'ed to the DVS-168 remote server host. Then a control message is sent over
the TCP socket that describes the alert and provides names for the data files. For non-national alerts, this is
the only notification by TCP needed. For EAN and EAT national alerts, the audio and text files are not
generated or sent, since EAN/EAT alert audio is live and of undetermined duration. When the alert ends, a
second control message is sent over the TCP socket to signal the end of the national alert. After this, the
socket connection is "torn-down". The Operation Log will log each of these actions and their success or
failure.

This toggle enables or disables CAP decoding for the DASDEC. Set it to enable to see all of the available
options for CAP Decoding.
Global CAP Options
The two advanced text to speech options (David and Allison) are available after a purchase of the License
Key (See the bottom of Setup > Server > Main/License). The download for the voice is available online, but
still requires activation. If the advanced text to speech options are not purchased, a basic text to speech
engine will be used.
CAP Text Message to Speech when CAP alert audio not available
Check this toggle to enable the text to speech option when there is no audio file sent with the CAP Alert.
Logging Options
These options are available to keep control over what CAP Alerts make it into the log of Decoded alerts.
