Vela NDU
The Vela NDU 710 is a sophisticated character generator controller and general messaging system from Vela Broadcast.
It comes with a complete EAS management system that controls a TFT-911 EAS encoder/decoder. The DASDEC II can
replace a TFT-911 in this system. It can be connected via a Null modem cable from the NDU serial port to the DASDEC II
serial port. The DASDEC II alert audio output must be wired to the selected NDU audio input port. The DASDEC II CG
setting must be set to TFT. After that, the NDU will run normally without further configuration. For details on the Vela NDU
701, refer to the literature at
www.vela.com .
Monroe Electronics Cable Envoy and CEMS 500/1000
The DASDEC II directly supports Monroe Electronics Cable Envoy multi-channel analog video CG and the CEMS
0500/1000 single channel analog video crawl overlay keyer. The Cable Envoy interacts with and acts as a controller for
the DASDEC II. For instance, it controls running audio from the DASDEC II. The CEMS unit is a basic CG to which the
DASDEC II can send text crawl commands. Both Monroe units require a straight through RS-232 cable. The Monroe
CEMS requires a DASDEC II TV license. See EAS equipment at

Keywest VDS-830/840/Starmu/Star-8
The DASDEC II directly supports the single channel analog Keywest Technology VDS-830 and 840 character generator
units. These units require a NULL modem RS-232 cable. The DASDEC II can crawl alert text on the VDS as well as
provide severity color coded backgrounds. The VDS-830 cannot key the crawl over a video background. It will replace the
full page with a gray background. The VDS-840 can key the crawling text over live video. The DASDEC II also has modes
to support the Starmu and Star-8 CG's. This option requires a DASDEC II TV license. See
www.keywesttechnology.com .
Chyron CODI
The DASDEC II can replace systems that operate Chyron CODI character generators. The DASDEC II supports both the
analog CODI as well as the Digibox CODI. The DASDEC II can crawl alert text overplayed on live video on these units.
The Digibox CODI provides SDI digital video input and output. The DASDEC II also supports simultaneous network based
control of multiple CODI Digibox units that provide a built-in LAN port. This option requires a DASDEC II TV and Plus
Package license. See
www.chyron.com .
Evertz Keyers
Evertz Logo Insertors, Media Keyers, and other digital and analog Evertz character generators are supported by the
DASDEC II 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 DASDEC II must be
equipped with an optional AES audio output or the DASDEC II Analog audio needs to be encoded into AES digital audio
with an A to D converter. The GPI EAS Audio output of the DASDEC II 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
DASDEC II 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.
NOTE: Two Evertz keyers can be run from one serial port output wired in parallel to two ports.
NOTE: Monroe Electronics manufactures the DASDEC II under license and markets it
under the name OneNet to the Cable and Telco markets.
