Frequently Asked Questions - CD8-MLAN YAMAHA

How to install the CD8-MLAN card in my Yamaha console?

Before installing the card, turn off the unit and disconnect the power cable. Discharge static electricity from your body by touching a metal surface. Carefully insert the card into the YGDAI connector of the console. Refer to the console's instruction manual for details.

Which cable to use to connect CD8-MLAN to a computer?

For a serial connection (Windows), use a D-SUB 9-pin to MINI DIN 8-pin cable to connect the SERIAL I/O connector to the computer's RS232C port. For a direct mLAN connection, use a standard 6-pin IEEE 1394 cable.

How to configure the DIP switches?

DIP switch 1 controls the serial port mode: ON for MIDI, OFF for use with mLAN Patchbay (PC). DIP switch 3 sets the model: ON for 02R, OFF for 03D. The other switches are factory set and should not be changed.

What do the LEDs on the card mean?

The mLAN LEDs (green/red) indicate connection status: green = leaf node, off = no connection, red = sound interruption if disconnected. The RT/ERR LED (green/red) indicates whether the card is root (green) or an error (red). The ACTIVE LED (blue) indicates that the relay function is active.

Can I transmit MIDI messages via mLAN?

Yes, set DIP switch 1 to ON (MIDI). For the 02R console, you will need an external device with a TO HOST and MIDI connector. For the 03D, directly connect the SERIAL I/O to the console's TO HOST connector.

What to do if the RT/ERR LED flashes red?

A red flash indicates an error. Check the network topology to avoid loops. If the LED is solid red, remove the faulty device from the bus. Refer to the Error Messages section of the manual for details.

How to use mLAN Patchbay with CD8-MLAN?

Install the mLAN Tools software from the provided CD-ROM. Make sure DIP switch 1 is set to OFF. Connect your computer to the SERIAL I/O port via a serial cable. mLAN Patchbay allows you to route MIDI and audio signals between connected devices.

What sampling rates are supported?

The card supports sampling rates of 44.1 kHz and 48 kHz.

Is the CD8-MLAN card compatible with consoles other than the 02R and 03D?

The card is specifically designed for Yamaha 02R and 03D digital recording consoles. Installation on other models is not guaranteed and could damage the equipment.

What to do in case of sound loss on the mLAN network?

First check the mLAN LEDs: if an LED is red, it means sound is interrupted. Check the connections and make sure no cable is disconnected. If the error persists, restart the main unit and connected devices.

These jacks are used to connect mLAN devices or IEEE1394-compatible devices via IEEE1394 standard (6-pin) cables. Each jack has an LED in the upper left corner to indicate the following statuses. green : The CD8-mLAN or connected device is a "leaf" node.

off : Not connected.

red : If the cable is disconnected, the sound will be interrupted on a connected device or other device.

③ RT/ERR LED

This LED indicates the following statuses.

green : The CD8-mLAN is a "root."

orange : An error has occurred. (IEEE1394 bus-related)

red : An error has occurred. (Other errors)

off : Status other than above.

NOTE Refer to "LED Messages" on page 11 for information on the error indication.

(4) ACTIVE LED

This LED indicates the following statuses.

blue : The relay function is active.

off : The relay function is disabled.

NOTE Since the CD8-mLAN will stop functioning as a bus relay when the power of the main unit is turned off, this LED will also correspond to the power on (lit blue) or off (dark) status.

Connections

Here's how to make connections from the CD8-mLAN to other mLAN devices or to your computer.

Connecting an mLAN (IEEE1394) device

Use an IEEE 1394 standard cable (6 pin) to connect the mLAN (IEEE 1394) jack of the CD8-mLAN to the mLAN (IEEE 1394) connector of the other mLAN (IEEE 1394) device. It is not necessary to turn off the power of the other mLAN (IEEE 1394) device or the 02R/03D before making these connections.

Connecting a Windows computer (serial connection)

Use a serial cable to connect the computer's RS232C jack to the CD8-mLAN's SERIAL I/O jack. At this time, make sure that the power to the computer and the 02R/03D is turned off.

NOTE Make this serial connection in order to input/output MIDI messages, or when using the included Windows software.

Use a standard D-SUB 9P MINI DIN 8P cable.

If you wish to transmit and receive MIDI messages via mLAN, you must also make the following connection.

NOTE In order to transmit and receive MIDI messages via mLAN, you must set DIP switch 1 to "ON (MIDI)."

Connections for transmitting/receiving MIDI messages

For the 02R

If you wish to transmit/receive MIDI messages via the CD8-mLAN installed in an 02R, you will need a separately sold external device (with power supply: e.g., an MU series tone generator) that has a TO HOST connector and MIDI connectors.

① Use an 8-pin system peripheral cable to connect the SERIAL I/O connector of the CD8-mLAN to the TO HOST connector of the external device.
② Use a MIDI cable to connect the MIDI OUT connector of the 02R to the MIDI IN connector of the external device. Similar, connect the MIDI OUT connector of the external device to the MIDI IN connector of the 02R. In this case, set the HOST SELECT switch of the external device to the "PC-2" position.

For the 03D

Use an 8-pin system peripheral cable to connect the SERIAL I/O connector of the CD8-mLAN to the TO HOST connector of the 03D.

NOTE For details on the signal flow, refer to "Internal Configuration of the CD8-mLAN" (p.9).
