3. Hardware description:
1. OFF/ Switch.
2. Micro USB - DC 5V Input.
3. USB Host Port.
4. MIDI OUTPUT.
5. LED indicator for MIDI OUT activity.
6. Power ON LED indicator.
4. Connecting:
1. Connect the Micro-USB (2) in to the DC Power adapter using the provided USB cable.
Make sure the unit is set to "OFF" (3).
2. Plug your USB device in to the USB Host Port (3) before powering CerebelUSB "ON".
3. Press the OFF/ON switch (1). The Power On LED indicator (6) will light up.
4. Connect the MIDI OUT port (4) to the MIDI IN of your desired device.
5. Play some notes or move some faders. When the USB-MIDI data is correctly transmitted to the
MIDI OUT port (4), the MIDI LED Indicator (5) will blink.

NOTE: Disconnecting and connecting USB devices repeatedly can cause improper recognition,
specially when using a HUB. If you experience issues turn CerebelUSB OFF and ON completely.
5. Power:
Even if CerebelUSB shares a 5V connection compatible with a huge amount of devices already available, it
is essential to use only our supplied 5V power adaptor.
Many USB devices are powered through their USB connection so any different voltage might cause
damage to the devices attached in the USB Host port. There is a protection circuitry inside the CerebelUSB
to protect against reverse polarity and over-voltage, but these are not guaranteed to prevent damage to
any attached USB device.
When using a HUB, all the attached devices will share the Power of the Host port. If these devices have a
high power consumption, you might experience a decrease in brightness or improper functioning.
Due to their differences and construction, there are other known issues regarding the use of a HUB.
For example, power drops, failure of recognition of secondary devices, etc. If you experience any issue try
changing to another USB HUB.

NOTE: For DIY applications where more than 5V are required, the unit can handle anything
between 4 to 12 Volts. The onboard power regulator converts the Voltage input in to the 3.3
Volts necessary for powering the internal circuit. Care must be taken due to the fact that any
Voltage applied to the DC Input will be transmitted automatically to the USB Host Port and MIDI
OUT Port, some devices might be permanently damaged if the wrong Voltage is used.
