Evertz Keyers
Evertz Logo Insertors, Media Keyers, and other digital and analog Evertz character
generators are supported by the EAS device using the SAGE generic CG protocol. The
Evertz unit must support an EAS option and be pre-programmed to recognize EAS
communication on the specific com port being used. For digital operation the EAS
device must be equipped with an optional AES audio output or the EAS device Analog
audio needs to be encoded into AES digital audio with an A to D converter. The GPI EAS
Audio output of the EAS device is used as an input to trigger voice-over activation on
the Evertz unit. The Evertz units handle all switching between normal program video/
audio to EAS play-out. The EAS device offers manual alert forwarding notification with
GPI output relay indication of pending alerts. This allows EAS to be forwarded when
appropriate, either manually by an operator or by automation. See the diagram below.
The directions provided by Evertz for the SAGE generic protocol has been tested by
Evertz and will work with the EAS device. See

.
XBOB CG
The EAS device can generate a crawl on a single video channel that is passed through
an XBOB. This option requires a valid TV license key.
BetaBrite LED sign
The EAS device supports driving the wide range of BetaBrite LED signs from a EAS
device serial port. A special cable is usually needed to connect the EAS device RS232
serial ports to a BetaBrite. The Betabrite protocol on the EAS device supports running
EAS alert text crawls immediately upon decoding as well as during alert origination and
forwarding.
Other Character Generators
Any character generator or turnkey system that can operate the standard TFT 911 EAS
serial control protocol or supports the SAGE Generic protocol can interface to a EAS
device. A Null modem cable from the CG serial port must be connected to the EAS
device serial port for TFT emulation. The serial cable required for units using the SAGE
Generic CG protocol depends on the unit.
Character generators that can be run from the SAGE generic CG protocol include
Evertz Keyers and Miranda ImageStore units. Also, for Miranda interfacing, refer to the
diagram above for Digital CG.
Utah Scientific SqueezeMax
Interfacing to a TV system with Utah Scientific SqueezeMax HD system with Utah
Scientific 2020 switcher, downstream mode.
The EAS device 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).
