RME Tech Info UCX Class Compliant

3. Operation

Activation of the Class Compliant mode

: Connect the UCX to power and switch it on. Turn the encoder

knob in Channel mode until SU appears in the display. Press the knob once to activate Level mode.

Turn the knob until CC is shown in the display, then press and hold the encoder until the display

shows on (pressing the knob again will make the display show oF, indicating CC mode is inactive).

The unit will reboot, all LEDs will light up, after which it will be in Class Compliant mode.

Check if CC mode is active:

CC mode is active when turning the encoder lists not only CC, but also C8

and CA in the display.

Connect the USB cable to the UCX and the Camera Connection Kit. Start the iPad and plug the

Camera Connection Kit into the Dock connector. If everything works as expected, the unit will enter

CC Host mode, indicated by the HOST LED turning off. Audio playback in iTunes will automatically be

performed by the UCX, using analog outputs 1/2 and the phones outputs 7/8 plus SPDIF/ADAT in

parallel (mode C8).

Apps that support MIDI and are ready for Core MIDI (available since iOS 4.2) will offer dialogs to

select the desired UCX MIDI inputs and outputs.

Useful hints

If the unit is not in CC mode, the iPad will detect an incompatible

USB device, and display a message saying “Cannot Use Device –

The connected USB device is not supported”.

When using hard covers as back panel protection for the iPad, the Connection Kit's plug may not fit

completely, causing a loose connection or partial functionality. If in doubt, remove the cover.

No sound: Incorrect output gain settings, see next chapter.

The iPad's volume control is inactive during USB operation.

If the unit does not enter Host mode:

Remove and reconnect the Connection

Kit.

Correct detection and operation of the

Connection Kit itself can be determined

in Settings / General / About. The

adapter will be listed there right after

connection, with additional details like

manufacturer, model number etc.

Connected USB devices, i.e. the UCX

will not be shown here, though.
