mLAN Configuration and Troubleshooting Tips

Application Notes
If your mLAN setup exhibits instability, you may
fi
nd these notes useful.
In the mLAN Control Panel:
•
If the audio seems to drop out frequently, the buffers are probably being overrun. Set the number
of buffers to a higher value and increase the buffer length. Note, however, that this will result in
higher latency.
•
For smoother performance without adding latency, try using more buffers with fewer
milliseconds per buffer. For example, instead of 2 buffers with 3 milliseconds each, try 6 buffers
with 1 millisecond each.
•
If the card generally has a dif
fi
cult time settling down, try setting the clock source on the mLAN
Control Panel after all other parameters are set, then click “set”. Note that it can take a few seconds
for the FireWire chain to lock onto the clock source. During these few seconds, you may see a
fl
ashing red timeout error message.
•
It is sometimes helpful to switch the sample rate on the control panel to another sample rate, then
back to the desired rate. This can ‘reset’ the way the mLAN control panel looks for clock in the
FireWire stream. It is also a good idea to switch the sample rate back and forth on the device in
which the mLAN card is installed, when resetting the clock in the control panel.
Note
: It is always necessary to click “Set” after changing any parameter in the mLAN control panel. After
clicking “Set”, it is almost always necessary to reassign the destinations by clicking on the “Select Source”
button under the “Receive” section of the mLAN control panel.
•
If the FireWire card is not plugged into the computer port on boot up, you may get an error from
the mLAN control panel indicating that there is no FireWire card installed, even on a computer
with a built in FireWire port. A restart with the connections intact will resolve this problem.
•
If any recording application using the mLAN ASIO driver is running, the mLAN control panel
will not allow changes, reporting that “some streams are in use”. Close the recording application
and then reopen the mLAN control panel to rectify the problem.
After the changes described above are made, the control panel should settle into smooth operation.
The following additional tips may be useful if you continue to experience dif
fi
culties.
Macintosh OS 9.x:
•
In the Extensions Manager, create an Extensions Set from the OS Base setting; deactivate Apple
Enet and TCP/IP; and activate only those extensions needed for the application you’re running
(for example, you’ll need to active iLok extensions for Nuendo, as well as OMS if you’re using it).
•
Check in the Energy Saver Control Panel’s Sleep Schedule page that all parameters are set to
NEVER.
•
Finally, especially with Titanium PowerBooks, make the FireWire connection
fi
rst, then power up
the KSP8, and
fi
nally power up the computer. Do not turn off the KSP8 until you have powered
down the computer, and do not disconnect FireWire while the computer is on.
