Sage Digital ENDEC Manual Rev 2.0
12.2.4.2 Relay Always On
If enabled, the ENDEC digital relay is always on, meaning the ENDEC’s digital audio transmitter is always
driving the Digital Audio Out signal. “Always” means after the ENDEC is turned on and starts up. When
the ENDEC is off, and for a short time after it is turned on, the ENDEC relay is OFF, meaning the ENDEC
digital transmitter is bypassed, and Digital Audio In is hardwired to Digital Audio Out.
12.2.4.3 Pass Through
When enabled, the ENDEC copies the Digital Audio In bit stream to the Digital Audio Out bit stream,
except when it is sending an alert.
12.2.4.4 Simulcast
When enabled, the ENDEC will always send an alert on the Digital Audio output at the same time that it
sends an alert on the analog outputs. If Simulcast is not enabled, the digital output can be sent
independently of the analog alert. The digital output is then treated as if it were station 4 on a multi-station
relay panel
12.2.4.5 External Clock
When External Clock is enabled, the ENDEC uses the input stream to derive its digital bit clock, otherwise
it will generate its own clock based on the Clock Rate setting. Note: even if External Clock is enabled,
Clock Rate must also be set to the correct rate.
12.2.4.6 Clock Rate
The ENDEC supports sample rates of 32 kHz, 44.1 kHz, and 48 kHz.
13. Network
While we provided tools to help keep the ENDEC secure, security is ultimately the responsibility of the
user.
The ENDEC is not a security device – if you plan to make the ENDEC available on the Internet, you must
also use a firewall to provide the necessary protection. You also need a firewall if your internal network is
shared with other users not associated with your station, particularly in a university or large corporate
setting.
This section discusses using the Sage Digital ENDEC on a LAN. Read and understand this section on
network security below before using the LAN with your ENDEC.
Important. Use a firewall to protect the ENDEC from unauthorized access.
13.1 ENDEC network use notes
• If the DCHP address type is selected, the ENDEC always attempts to get an IP address. If you do
not want the ENDEC on the LAN, do not connect a cable to the RJ-45 LAN port on the back of the
ENDEC (labeled LAN 10/100).
• NTP (Network Time Protocol) is enabled. The ENDEC does not allow remote control of the NTP
settings via the NTP protocol. It does allow you to specify a list of servers via ENDECSETD.
Time (NTP) Servers. See section 13.2.1, Time (NTP) Servers.
• By default, all control functions that would generate EAS alerts using the LAN are disabled. This
includes the Web server, the automation interface, and the ENDEC PRO/DJ LAN interface. To
