Network
The cable type most commonly used today is CAT5e. For more detailed information, please refer to the
document “
Building ES Networks
”, available on the enclosed CD-ROM and on our web site.
The network connections are established via two Neutrik

receptacles. Connection is very easy: use the connector labeled “IN” to connect the
descending EtherSound stream (
downstream
, coming from the ‘
Clock Source
’), the
connector labeled “OUT” to connect the ascending EtherSound stream (‘
upstream’
).
The Neutrik
TM

TM
RJ45 provide secure connection through a latching
system. To disconnect the cable from the device, press the latch, then withdraw the
cable while maintaining the latch pushed.
Example 1: bi-directional point-to-point transmission of eight audio channels
This application is very easy with EtherSound ES881v2, ES1241v2, and ES16161v2.
Connect a standard Ethernet cable between the “OUT” port of the first Ethernet bridge to the “IN” port of the
second Ethernet bridge. Bring into line the EtherSound channels on the two devices (see the on-line help of
the configuration software).
Example 2: more complex architectures
System topology may be
daisy chain
,
star
, ring, or a combination of star and daisy chain. By default, the first
device in a network, such as an EtherSound ES881v2, provides the master clock for the entire network. This
device is called ‘Clock Source’. Note that in a ring configuration you must configure a device as Clock Source
(this is done by software, the device is then called ‘
Preferred Clock Source’
). Nevertheless, you have the
possibility to synchronize the ‘Clock Source’ device on an external clock by using the ‘
Word Clock In
’ input
and by then providing this clock to the EtherSound bridges downstream from the ‘
Clock Source
’ passing
through the ‘
Word Clock Out
’ outputs.
Connect the “OUT” port with the “IN” port of the following EtherSound device.
Repeat this step for each device in the network. The maximum distance between two devices is 100 meters
(
≈
330 feet). Intermediate switches or fiber optic links may be used to considerably increase this distance.
On ES881v2,
between 44.1 kHz and 48
Preset efault value is 48 kHz.
Note: These operations require opening of the cabinet and shall be done by qualified personnel only.
