6CobraNet [PRIMARY]/[SECONDARY]
Connectors
The DME Satellite features two CobraNet connectors for
built-in redundancy: one for a primary network connection,
another for a secondary or backup connection. If for some
reason the primary connection fails (e.g., a cable is damaged,
inadvertently disconnected, or a switching hub fails), the sec-
ondary connection automatically kicks in. Audio transmis-
sion is momentarily interrupted, but the duration of
interruption varies depending on the hub performance or
settings, and the system configuration.
7MAC Address
This is the CobraNet’s MAC (Media Access Control) ad-
dress.
8[GPI] Connector
This Euroblock connector provides access to the unit’s GPI
(General Purpose Interface) interface for transfer of control
signals to and from external equipment. It features 8-port in-
put and 4-port output. The +V terminals have an output
voltage of 5 volts. The IN terminal detects voltage changes
from 0V to 5V. The OUT terminals output either signal “L”
or “H” at a TTL level. (See page 34.)
9[INPUT] Connectors
These Euroblock connectors receive 8-channel analog audio
signals on the DME8i-C.
These Euroblock connectors receive 4-channel analog audio
signals on the DME4io-C.
)[OUTPUT] Connectors
These Euroblock connectors output 8-channel analog audio
signals on the DME8o-C.
These Euroblock connectors output 4-channel analog audio
signals on the DME4io-C.
NOTE
•You can check the CobraNet connection status by looking at
the [IN USE/CONDUCTOR] and [LINK ACTIVITY]
indicators. The indicators on both sides to the CobraNet
connectors are turned off.
•Use a STP (Shielded Twisted Pair) cable to prevent
electromagnetic interference.
NOTE
•The PAD will be internally switched on or off when the gain of
the DME8i-C/DME4io-C internal head amp is adjusted
between –6 dB and –5 dB. Keep in mind that noise may be
generated if there is a difference between the Hot and Cold
output impedance of the external device connected to the
INPUT connector when using phantom power.
