FCC Statement for MIDI USB Host
NOTE : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Important
This product will ONLY work with USB devices which are MIDI Class Compliant.
Check in the product manual or contact the manufacturers to establish if the
device you intend to attach is Class Compliant.
If you attach a non class compliant device, it just won’t be recognised. No
damage will be caused to either the host or the device.
Description
The MIDI USB Host has a USB Host port (USB A socket), a MIDI IN and a MIDI OUT
(both 5 pin DIN). MIDI data received at the MIDI IN socket will be sent to the
USB device. MIDI data received from the USB device will be sent to the MIDI
OUT socket.
The MIDI USB Host is powered by a regulated 5V mains adaptor (supplied), and
can supply up to 910mA of buss power to the attached USB device.
Connecting
The supplied USB cable is for connecting the MIDI USB Host Mini-B power socket to the supplied power adaptor ONLY. Note that the Mini-B socket is for power ONLY, it is not a USB port.
It is recommended that you attach your USB device to the MIDI USB Host before
applying power. Then plug-in and power the power adaptor. The active LED
should be lit up. If you apply power with nothing plugged into the MIDI USB
Host, the Active LED will flash steadily; this is to indicate that it is
waiting for a suitable device to be attached. If it is still flashing when you
have attached your device, then it is possible that your device is not class
compliant, however you could try turning off the power and start again.
Some USB MIDI devices have two modes of operation and can be set to operate in
Class Compliant mode even if this is not the default. The Class Compliant mode
might be called “generic driver”, the other mode may be called something like
“advanced driver”. Consult the device manual to see if the mode can be set for
Class Compliant.
If you unplug then re-plug the USB cable connected to the device while it is powered, the device might reconnect but it is not certain.
Power
It is essential to use only the supplied 5V regulated power adaptor. Applying
a voltage higher than 5V to the MIDI USB Host will probably not damage the
MIDI USB Host itself, but it could damage any attached USB device as the 5V is
passed on to the attached USB device for buss power. There is protection
circuitry inside the MIDI USB Host to protect against reverse polarity and
over-voltage, but these should be treated as a last resort and are not
guaranteed to prevent damage to an attached USB device in the event of over-
voltage as the USB buss voltage could rise to 6.5V before being clamped. Care
should be taken to ensure that power adaptors for other pieces of equipment
are not accidentally plugged into the MIDI USB Host.
If the input voltage rises above 6.5 volts then power will be shut off. The LED will go out and the unit will not operate again until power has been removed for at least 60 seconds. This allows time for the thermal fuse to reset.
The supplied multi-region power adaptor will operate over a wide range of voltages and is consequently suitable for use in most parts of the world.
Firmware version Request:
You can send a SysEx message to request the version number of the firmware
currently installed in the unit.
The firmware version request message is – F0 00 20 13 13 60 F7 (hex)
The unit replies with the version number as F0 00 20 13 13 6F xx xx xx xx F7
(hex).
Where xx is a number in ASCII and the leftmost digit is the most significant.
For example – F0 00 20 13 0E 6F 31 32 33 34 F7 (hex) = version number 1234
