Troubleshooting

• There may be a limit on the IEEE 1394 interface of your com-

puter as to the number of ports that can be used simultaneously.

Check how many ports can be used simultaneously.

•Turn off all devices on the mLAN network (except the com-

puter) and re-connect each device one-by-one until the device

causing the problem is found.

•(For Windows) (When removing the mLAN bus from the

[Safely Remove Hardware] setting of the task bar.) Restart the

computer when using mLAN again.

•With Macintosh notebook computers such as the iBook and

PowerBook, always ﬁrst connect the 01X and mLAN cable

then turn on the power of the 01X, before starting up the com-

puter.

•Make sure that you set up the wordclock correctly. Also, make

sure that one node is assigned as master and the other nodes are

assigned as slaves.

........“The mLAN connection does not work.”

■The computer processing speed is too slow.■The computer’s CPU meter indicates a heavy processing load.■Playback response is delayed.

• Make sure your computer satisﬁes the system requirements.

........“System Requirements” (Installation Guide)

•(For Windows) If you do not use the mLAN system, on the task

bar right-click mLAN Manager (mLAN icon), then select OFF

(mLAN quits).

........“Conﬁrming the installation” (Installation Guide)

•Try reducing the number of audio channels in mLAN Auto

Connector or Graphic Patchbay.

•Try increasing the latency value.

........“Changing the Settings after Installation”

(Installation Guide)

•(For Macintosh) If a dual-CPU model awakes from Sleep or

Suspend mode, processing speed may be slowed. In this event,

restart the computer.

•(For Windows) Refer to “Hints when using

audio data (Windows).”..............................Installation Guide

•(For Windows) The condition may improve if you set “Hyper

Threading” to “Disable.”

•(For Macintosh) Turn off virtual memory.

•(For Macintosh) Disable Apple Talk.

■Inconsistency in wordclock, or unable to exit from Auto Connector

•(For Windows) Mobile computers with Intel CPU

SpeedStep™ technology is applied for some CPU’s (CPU for

notebook PC). Please disable the SpeedStep™ technology

when mLAN is employed. SpeedStep™ technology changes

CPU clock dynamically depending on the loading on the CPU

to save the power consumption.

•How to disable the SpeedStep™ technology;

In almost all of the PC’s, BIOS has a function to select

enabling or disabling the SpeedStep™ technology. Please

refer to the PC’s operating manual, or make inquiry to the

PC manufacturer.
