PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death
from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are
not limited to, the following:
• Before installing the MY16-CII in an audio device please check to make sure that the device is compatible
with the MY16-CII and check possible restrictions regarding the maximum number of Yamaha and thirdparty expansion cards that can be simultaneously installed. Refer to the operation manual supplied with the
audio device, and/or the Yamaha Pro Audio web site at: http://www.yamahaproaudio.com/
• Do not install the MY16-CII card in any Yamaha products not specified by Yamaha for use with the MY16-CII
to avoid possible electrical shock, fire, or equipment damage.
• Do not attempt to disassemble or modify the card. Do not apply excessive force to card connectors or other
card components. Mishandling of the card may lead to shock, fire hazard, or equipment failure.
• Be sure to disconnect the power cable of the main unit before installing this card (in order to eliminate shock
hazard).
• Turn off all peripheral devices connected to the host device before installation, and unplug all related cables.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others,
or damage to the device or other property. These precautions include, but are not limited to, the following:
• Do not touch the metallic leads (pins) of the circuit board when handling the card. The pins are sharp and
may cause hand cuts.
• Wear a pair of heavy gloves during installation to avoid scratching or cutting your hands on sharp edges.
• Avoid touching exposed connectors and metal parts to minimize the possibility of bad connections.
• Drain all static electricity from your clothing and body before handling the card. Static electricity can damage
the card. Touch an exposed metal part of the host device or other grounded object beforehand.
• Do not drop the card or subject it to physical shock as this can result in breakage and/or malfunction.
• Do not drop screws or other small parts inside the card. If power is applied while screws or similar metal
objects are loose inside the unit the card may malfunction or be damaged. If you cannot retrieve dropped
objects yourself, refer the problem to qualified Yamaha service personnel.

Greetings
Thank you for choosing the Yamaha MY16-CII CobraNet™ INTERFACE CARD.
The MY16-CII is a CobraNet™* expansion card for use with compatible Yamaha professional
audio equipment. Complying to CobraNet™ standards, the MY16-CII allows transmission and
reception of up to 32 channels (16 in/16 out) of uncompressed digital audio data.
* CobraNet™: An audio networking system developed by Cirrus Logic, Inc. that allows real-time
transmission and reception of multiple channels of uncompressed digital audio signals via a Fast
Ethernet (100 megabits/sec.) network. A single network cable can handle a maximum of 64
channels (128 channels bidirectional) of audio data.
In order to take full advantage of the advanced features and performance provided by the
MY16-CII card we urge you to read this manual thoroughly, and keep it in a safe place for further
reference.
Before installing the MY16-CII in an audio device please check to make sure that the device is
compatible with the MY16-CII and check possible restrictions regarding the maximum number of
Yamaha and third-party expansion cards that can be simultaneously installed.

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:
■
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.

Multicast Bundles and Unicast Bundles
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.
Multicast Bundles
Multicast bundles transmitted from device A are
sent to all devices on the network (B through D in
the example).
Unicast Bundles
Unicast bundles are received only by devices set to
receive the same bundle numbers as the transmit
bundle number of the transmitting device A (device
D in this example).
