System Examples

Daisy Chain Connection

In this example an MY16-ES64 EtherSound interface card is installed in a Yamaha M7CL or LS9 digital mixing console and
connected to multiple SB168-ES units. In this type of system an MY16-EX I/O expansion card is also required for each addi-
tional SB168-ES unit connected in the daisy chain (i.e. for three SB168-ES units one MY16-ES64 card and two MY16-EX
cards are required).
The EtherSound [OUT] connector on the MY16-ES64 card is connected to the [IN] connector of the first SB168-ES unit, and
subsequent units are daisy chained as shown in the diagram. A computer can be connected to the EtherSound [IN] connector on
the MY16-ES64 card functioning as Primary Master.

Daisy Chain Characteristics
• Four daisy chained SB168-ES units provide a total of 64 input channels and 32 output channels.
• The computer can remain connected at all times, making it possible to use the AVS-ESMonitor application to control the SB168-ES head ampli-
fiers and continuously monitor the EtherSound network.
• If a connection is broken in a daisy chain network, the signal flow is interrupted at that point and no signal will be transferred beyond that point.

Ring Connection

As in the daisy chain example above, an MY16-ES64 EtherSound interface card is used to connect the digital mixing console to
the SB168-ES units. The EtherSound [OUT] connector is connected to the EtherSound [IN] connector of the subsequent unit,
and the EtherSound [OUT] connector of the final SB168-ES unit is connected back to the EtherSound [IN] connector of the
MY16-ES64 card.

Ring Connection Characteristics
• The EtherSound specifications limit the total number of input and output channels to 64 in this type of network.
• The AVS-ESMonitor application cannot be used during system operation. An EtherSound device with a third port is required to connect a com-
puter running AVS-ESMonitor into the ring.
• A problem at one point in the network will not affect operation of the entire network.
• In ring connections it is particularly important to ensure that all EtherSound devices are running the latest firmware (page 6).
