About CobraNet
About
CobraNet is …
An audio networking system developed by Cirrus Logic, Inc. that allows real-time transmission and
reception of uncompressed digital audio signals via a Fast Ethernet network cable. The network can
simultaneously handle up to 64 input and output channels, for a total of 128 channels (64 channels if
repeater hubs are used). The maximum number of channels than can be handled in practical situations
may be lower due to performance limitations imposed by the equipment used and the condition of the
audio signal.
Currently, the CobraNet network will handle 16, 20, or 24-bit audio at sampling rates of 48 or 96 kHz.
The CobraNet network is capable of transmitting control data at the same time as the audio signals. The
types of control data transmitted are determined by the equipment used.
The CobraNet network imposes a 5.33-millisecond (2.67 milliseconds or 1.33 milliseconds with some
settings) latency on transferred audio signals. Latency and bit depth can be set via the CobraNet
Manager application.
Refer to the CobraNet home page for more details: http://www.cobranet.info/
Bundles
Audio is transmitted over the CobraNet network in units known as “bundles.” These bundles are
processed at the receiving end to reconstitute the original audio signals. In the case of the MY16-CII a
bundle can contain up to eight channels. Each bundle is identified by a number from 1 to 65,279, and
audio transmission via the network becomes possible when the same bundle number is specified at both
the transmitting and receiving devices. Bundles can be transmitted and received over the entire network
as long as sufficient network resources are available. The actual number of bundles that can be handled
will depend on the capabilities of the equipment used.
The MY16-CII can use up to 4 output bundles and up to 8 input bundles. Bundle numbers can be
assigned via the CobraNet Manager application.

CobraNet Device CobraNet Device
Two types of bundle can be used with CobraNet: “multicast” bundles and ‘‘unicast’’ bundles. Multicast
bundles can be transmitted from a single device to all devices on the network, while unicast bundles are
transferred from a single transmitting device to a single receiving device or a limited number of receiving
devices.
Unicast bundles are only sent to devices which have been set to the same bundle number as the
transmitting device. Multicast bundles are sent to all devices on the network regardless of their settings,
but only bundles with the specified bundle number(s) are processed. For this reason multicast bundles
make heavy use of network resources and it is recommended that the maximum number of bundles be
limited to 4 (32 channels). Unicast bundles should be employed when it is necessary to handle 5 or more
bundles at a time. It is also possible to set multiple devices to receive the same unicast bundle number,
and depending on the transmitting device up to 4 receiving devices may be able to simultaneously
receive the same bundle. This situation is known as “multi-unicast.” The MY16-CII is capable of handling
multi-unicast bundles.
Different number ranges are used for multicast and unicast bundles: multicast bundles are numbered 1
through 255, while unicast bundles are numbered 256 through 65,279.

Conductor and Performers
A
C
E
D
B
Conductors transmit the
synchronization signal that is received
and used by performers. Clock
synchronization is necessary to
transfer digital audio data to and from
devices outside the CobraNet network.
In this example device C on the
CobraNet network sends the
synchronization signal to external
device E.
Conductor (Transmit) Performer (Receive)
Sync
(Word Clock)
Network
Performer
(Receive)
Performer (Receive)
External Digital Device
On any CobraNet network one device generates a timing signal that all other devices receive and are
synchronized to. The device that generates the synchronization signal is known as the “conductor,” while
all other devices are “performers.”
The conductor for the network is automatically assigned and need not be specified by the operator.
When an MY16-CII is assigned to be the conductor for the network, the LED indicator to the left of the
connector that is connected to the network will flash orange. If the conductor fails for some reason,
conductor status is automatically switched to another device on the network.
Since the conductor transmits the synchronization signal to the performers via the network cable, no
separate word clock cables are required and the total number of cables used by the system is kept to a
minimum. Digital audio devices that are not connected to the network, however, will need to receive a
word clock signal from a device on the network in order to achieve synchronization.
NOTE Digital signals and control data are transmitted and received by all conductor and performer devices on the
CobraNet network.
CobraNet Cables and Network Switch
Category-5 metal cables can be used for runs of up to 100 meters, while multimode optical fiber cables
can be used for runs of up to 2 kilometers.
Always use network switch in a CobraNet network. When using metal cable for connections, be sure to
use Category 5 straight cables.

Control Data
The MY16-CII handles 16 channels of audio input and output that are assigned to bundles that will be
transmitted and received to and from the appropriate network devices.
The MY16-CII can use up to 4 output bundles and up to 8 input bundles.
The maximum number of channels that can be assigned to each bundle is as follows.

* Since 96-kHz audio is handled as two 48-kHz signals combined, the maximum number of channels is halved.
** The audio signal output from the 4th channel will include some aliasing noise, and proper operation cannot be guaranteed.
Please do not use this channel.
NOTE The number of channels per bundled can be changes as shown below.
Depending on the configuration, the maximum number of channels that can be handle may be less than 8.

1 [PRIMARY] and 2 [SECONDARY] Connectors
These are 100Base-TX Ethernet connectors. The MY16-CII provides two Ethernet connectors to allow
construction of redundancy networks employing dual (primary and secondary) circuits. The [PRIMARY]
connector is for connection to the main circuit, while the [SECONDARY] connector is for connection to
the backup circuit.
If a failure occurs on the PRIMARY circuit (e.g. a cable failure, accidental disconnection, network switch
failure, etc.) the SECONDARY circuit will automatically take over. Basic redundancy network setup is
described on page13.
Use STP (Shielded Twisted Pair) cables to protect against electromagnetic interference.
3 [IN USE/CONDUCTOR] Indicators
These are the LED indicators to the left of the [PRIMARY] and [SECONDARY] connectors.
These indicators will light when power has been properly applied to the MY16-CII card. These indicators
will flash when the MY16-CII is operating as the network conductor. If an error occurs on the connected
network, both the [PRIMARY] and [SECONDARY] connector [IN USE/CONDUCTOR] indicators will flash
orange.
If both the [PRIMARY] and [SECONDARY] connector [IN USE/CONDUCTOR] indicators flash orange,
try disconnecting the corresponding Ethernet connectors. The indicator will go out if a cable, network
switch, or other device connected to the network has failed. If the indicator continues flashing orange
even after the cable is disconnected, there may be a fault in the MY16-CII card itself. In this case please
refer the problem to qualified Yamaha service personnel.

4 [LINK/ACTIVITY] Indicators
These are green indicators to the right of the [PRIMARY] and [SECONDARY] connectors. The indicator
for each connector will light or flash slowly when a network cable is properly connected, and will flash
rapidly while data is being properly transferred via the corresponding connector.
5 MAC Address
The MAC (Media Access Control) address allows the CobraNet Manager to differentiate between
individual MY16-CII unuts.

NOTE Redundancy Networks
Redundancy networks employ dual (primary and secondary) circuits. Communication usually occurs over the
primary circuit, but if a failure occurs on the primary circuit – cable failure, accidental disconnection, switch
failure, etc. – the secondary circuit will automatically take over. Redundancy networks offer significantly higher
reliability compared to single-circuit systems.
