31. Operation
Activation of the Class Compliant mode: Remove USB and FireWire cable from the UFX. Press
SETUP/REV. Turn encoder 1 until Options appears in the display. Turn encoder 2 until Hard-
ware/Diagnosis appears. Push encoder 2 several times to select the entry CC Mode. Turn en-
coder 2 to switch CC mode on (or off). The UFX reboots, all LEDs light up, after which it will be
in Class Compliant mode.
The option CC Routing offers two different routings of the playback signals. See chapter 34.
Connect the USB cable to the UFX and the Camera Connection Kit. Start the iPhone/iPad and
connect the Camera Connection Kit. If everything works as expected, the unit will enter CC host
mode, indicated by the blue USB LED turning on. Audio playback in iTunes will automatically be
performed by the UFX, using analog outputs 1/2 and the phones outputs 9/10, 11/12, AES and
ADAT (routing Phones).
Apps that support MIDI and are ready for Core MIDI (available since iOS 4.2) will offer dialogs
to select the desired UFX MIDI inputs and outputs.
31.1 Useful hints
If the unit is not in CC mode, the iPhone/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 chapter 34.
The iPhone/iPad 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
UFX will not be shown here,
though.
