If your software does not see all of the inputs or outputs of your MOTU interface, launch the interface's console to see if everything is configured properly.

For FireWire interfaces:

• See if "Optical Input" and "Optical Output" are set to none; if they are, change them to the desired format. If you are not using the optical I/O, set them to "None" to save FireWire bandwidth.

For PCI interfaces:

• Use the "Configure Interface" drop-down menu to choose which interface's properties you are viewing.
• Check "Enable Routing".
• For the PCI-424 card, each pair will have a check box to independently enable input and output. Enable each input and output pair you wish to have available. If you are not using input or output pairs, uncheck the "Enable Input" or "Enable Output" box to disable them to save PCI bandwidth.
• For the PCI-324 card, each pair will have a check box to enable its input and a drop-down menu to select "None", "From Computer", or any enabled input pair. To enable the inputs, check the box; to enable the outputs, set them to "From Computer". If you are not using input or output pairs, uncheck the "Enable Input" box and set the output drop-down menu to "None" to disable them to save PCI bandwidth.
• For the 2408/2408mk2/2408mk3, set each bank to be the desired format: Analog, ADAT, TDIF, or S/PDIF. Remember that S/PDIF must be on Bank C.
