downstream mode.
The DASDEC II can interface to multiple SqueezeMax units using the LAN based EAS NET protocol, but the alert must be
played on all SqueezeMax units at the same time. EAS NET sends alert text to each interfaced SqueezeMax unit and
then goes into a pending alert play-out state. The text alert sent to the SqueezeMax places it into a pending EAS play-out
mode. The EAS crawl can then be triggered manually on the SqueezeMax via 2020 Master Control switcher when desired
(within a few minutes). Master Control supports this action via a custom macro, associated with a panel button, which
triggers the SqueezeMax EAS preset, switches audio output to the DASDEC II input, and produces a GPI contact closure
for triggering alert play-out on the DASDEC II. The DASDEC II goes out of pending alert mode and plays the alert audio
until finished. When the alert is finished, SqueezeMax is taken out of EAS display and Master Control returns audio back
to normal program audio.
The DASDEC II can also be directly connected to a single SqueezeMax using a serial connection.

Refer to description above for the SqueezeMax. A DASDEC II can interface to mixed SD and HD SqueezeMax units, but
as described above, the alert must be played on all units at the same time.
