CobraNet [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.

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 31.)

[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 CAT5 STP (Shielded Twisted Pair) cable to prevent
electromagnetic interference.
