Sage Digital ENDEC Manual Rev 2.0
8) Use ENDECSetD to configure your ENDEC with:
• Call sign – config tab
• Local Area – local area tab
• UTC Offset – config tag
• NTP (time) servers – network tab
• Filters for the types of messages you want to relay – incoming filter tab
9) Determine how you will receive CAP messages This is usually the Internet, but can also be a multicast
satellite receiver, or a VPN. Always use a firewall and additional access controls when connecting
your ENDEC to the Internet.
10) Connect the ENDEC to your air chain. We suggest that you don’t do this right away, get your setup
right, check the input levels, practice sending RWTs to the front panel speaker, etc.
Since an EAS alert can air automatically and unattended, the ENDEC needs to be able to switch out
your program audio and switch in its alert audio. You can pass through audio through the ENDEC
and use the ENDEC’s internal switching:
• Main Audio IN and Main Audio Out XLR connectors. This is the easiest way to switch out the
program audio and switch in the alert audio. Use connectors on the back of the ENDEC to
place the ENDEC between the console and other station audio sources and the transmitter (or
STL). The ENDEC is usually placed before any audio processing. See Figure 2-1.
• Digital Audio AES/EBU Connectors. When you use the digital audio IN and OUT ports, the
ENDEC automatically interrupts digital audio. If you use an external switch, you can use the
digital audio OUT port to provide digital audio to the switcher. In either case, the ENDEC
provides its own clock or it can derive clock from the digital audio IN port.
You can also use an external switcher. Connect the ENDEC’s digital output or analog output to the
alternate input on your switch, and trigger the switch from one of the ENDEC’s dry contract closures,
use a relay assigned to PTT.
EAS alert data usually pass through audio processing. If you place the ENDEC in front of profanity
or program delay equipment, be aware that these devices will stretch audio when they rebuild their
buffer. They keep pitch while slowing time – this process will corrupt EAS data making alerts you
relay not decodable. The FCC has certain minimum modulation levels in Part 11.
In a TV station:
a. place the character generator in the video chain and
b. connect the ENDEC to the CGEN with a serial cable. Select the type of character generator on
the DEVICE tab. Many character generator manufacturers provide an interface for Sage
systems that use the serial port and an audio input port to handle both audio and video in the
same box.
11) Connect any other options, such as remote controllers, multi-station relay panels, external switcher or
LED signs.
12) Enable logging. The ENDEC can log to any combination of:
• An attached USB printer
• a LAN-connected network printer
• a list of email addresses
• an FTP server
The ENDEC will always log to its internal FLASH memory.
