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 video 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 forwarding. GPO relay 2 is still programmable,
but supports fewer options.
