1. Audio
connectors
On ES220, a Sub-D 15 connector is used to input two balanced analog signals
and to output two balanced analog signals.
On ES220-L, only one of these two functions is accessible depending on the
configuration selected (for connector pinout see appendix C).
2. Network
connectors
These two EtherCon
TM
Neutrik
TM
RJ45 connectors allow for a steady and
reliable connection to the EtherSound network. The “IN” port allows
connecting the ES220 to the equipment upstream, while the “OUT” port
allows connecting the ES220 to the equipment downstream. When an ES220
receives a descending stream on its “IN” port, it transmits it to its “OUT” port,
after - if required - having injected two EtherSound channels (if this device is
not the last element of the EtherSound chain). When an ES220 receives an
ascending stream on its “OUT” port, it transmits it to its “IN” port, after - if
required - having injected two EtherSound channels (if this device is not the
Primary Master). For more details, see the document “EtherSound Overview”
(available on our Web site).
3. GPIO
connector
This connector allows setup of external control and monitoring devices
through configurable and protected General Purpose Inputs and Outputs. See
appendix D dedicated to the GPIOs for more details.
Note:
the GPIO port is managed by configuration software only.

Power supply connector
4-pin Mini DIN connector (for the connector pinout see it appendix G).
