About Console Network and I/O Network
• Console Network
A DSP engine is equipped with a special control
surface terminal. You can connect a control surface to
a DSP engine. A network created by the control surface
and a DSP engine is called a “Console Network.”
•I/O Network
A DSP engine and I/O racks are connected via a
TWINLANe network, using an HY card slot. A
network created by a DSP engine and I/O racks is
called an “I/O Network.”
TWINLANe network
TWINLANe is Yamaha’s proprietary audio transfer
network protocol. With this protocol, 400-channel digital
audio and control signals can be transfered via a single
cable simultaneously.
To connect devices, first install a TWINLANe network
card in an HY card slot of each device, then use fiber optic
cables to connect the TWINLANe network cards in a ring
network topology.
* If the number of connected devices is much larger, or if the
total length of all cables is too long, the listed value may not
apply.
NOTE
Yamaha recommends that you use opticalCON DUO fiber cable
made by Neutrik. In general, fiber optic cables are susceptible to
bending or pulling. Use a fiber optic cable that features a strong
plastic jacket and lock mechanism to avoid cable-related
problems.
About cleaning
If dirt or dust attached to the contact surface of jacks on
the fiber optic cables or connectors on the device, data
may not be transferred properly. Clean the contact surface
of jacks and connectors regularly using a commercially-
available fiber optic cleaning tool.
