32. Operation
In factory default setting Interface Mode – Auto the UFX+ will not automatically switch to CC
mode as soon as an iPad or iPhone is connected. Instead it switches to mode USB 2, and
iPhone/iPad show a warning of an unsupported device. The CC mode always has to be acti-
vated manually.
Activation of the Class Compliant mode
: Remove USB and Thunderbolt cable from the UFX+.
Press SETUP/REV. Turn encoder 1 until Options appears in the display. Turn encoder 2 until
Hardware/Diagnosis appears. Push encoder 2 several times to select the entry Interface Mode.
Turn encoder 2 to switch to CC mode. 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 35.
Connect the USB cable to the UFX+ and the Lightning to USB adapter. Start the iPhone/iPad
and plug-in the adapter. If everything works as expected, the unit will enter CC host mode, indi-
cated by the orange USB LED turning on. Audio playback will automatically be performed by
the UFX+, using analog outputs 1/2 and the phones outputs 9/10, 11/12 (with routing option
Phones activated).
Apps that support MIDI and are ready for Core MIDI will offer dialogs to select the desired UFX+
MIDI inputs and outputs.
32.1 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 Kit's/adapter’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 35. Note that the iPhone/iPad volume
control is inactive during USB operation.
If the unit does not enter Host mode: Remove and reconnect the Connection Kit.
Having tested several chinese replicas of the Apple Camera Connection Kit, from 2-in-1 to
5-in-1 adapters, we strongly recommend purchasing the original!
All adapters seemed to work for the simple application of copying photos. Attempting to run the
UFX+ with USB Audio 2.0 was when the problems started. Some of the tested adapters would
not work at all, others only with short cables, and only one adapter came close to the quality of
the original. But as soon as 8-channel recording or 96 kHz playback was initiated, the Apple Kit
always performed much better.
Similar problems with the newer USB to Lightning adapter are not known.
Since 2016 Apple offers another version of the USB to Lightning Adapter, called Lightning to
USB 3 Camera Adapter. It has an additional Lightning port for power supply that charges the
iPhone/iPad even when used with the UFX+.
