6 [REMOTE] Connector
This 9-pin D-SUB connector allows connection to a Yamaha
AD824 or AD8HR remote head amplifier or an RS-232C/
RS-422 compatible controller such as those from AMX or
Crestron. You can also connect a Yamaha PM5D or DM2000
and control the internal head amps of the DME8i-ES/
DME4io-ES. See “Remote Connection ([REMOTE] Con-
nector)” on page 26 for connection details.
7 EtherSound [IN]/[OUT] Connectors
These connectors input and output audio signals and control
signals between devices. Use an Ethernet cable (CAT5e or
higher category) to daisy-chain multiple DME Satellite
units.
For more about EtherSound connections, refer to pages 24
and 28.
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 30.)
9 [INPUT] Connectors
These Euroblock connectors receive 8-channel analog audio
signals on the DME8i-ES.
These Euroblock connectors receive 4-channel analog audio
signals on the DME4io-ES.
) [OUTPUT] Connectors
These Euroblock connectors output 8-channel analog audio
signals on the DME8o-ES.
These Euroblock connectors output 4-channel analog audio
signals on the DME4io-ES.
Precautions for Using a
Rack-mounted DME Satellite
If several DME Satellite units (or a DME Satellite unit to-
gether with other devices) are installed in a poorly-ventilated
rack, the heat generated by each unit may raise the tempera-
ture inside the rack, preventing the DME Satellite from per-
forming as designed. When mounting DME Satellite units
in a rack, please leave one rack space vacant for every two
units. You can attach a ventilation panel to this space or leave
it open to prevent excessive heat build-up.
If the temperature inside the rack is expected to rise above 40
degrees Celsius or 104 degrees Fahrenheit (or if the ambient
temperature outside the rack is expected to rise above 30 de-
grees Celsius or 86 Fahrenheit), install a fan kit in the top
row of the rack. The fan must provide airflow of 1.6m
3
/min
or more and static pressure of 5mmH
2
O or more.
NOTE
• The communication status of the EtherSound [IN]/[OUT]
jacks is shown by the front panel [TX/RX] indicators.
•Use a STP (Shielded Twisted Pair) cable to prevent
electromagnetic interference.
