Kenton Killamix Mini - Manual (Page 9)

9
Power the unit on (plug into USB port) whilst holding buttons 7 & 9 pressed down. Allow a
couple of seconds for the USB interface to initialise then release the buttons. Various buttons
will light up depending on the status of various checks made. Ideally buttons 1,2,3,4 & 5 will
light up at this stage, indicating that the unit is completely ready to receive a firmware upgrade.
See later for what to do if this is not the case.
Load the file into your software (if necessary) and start the SysEx file dump from your
computer. The procedure should only take a few seconds. If everything goes as it should, all 9
of the buttons should be lit up when the download procedure has been completed and the
received file has been checked. You now need to press button #9 to confirm that you want to
perform the final irreversible copy operation to complete the upgrade. A few seconds after you
have done this, buttons 1 to 8 will go out leaving button #9 alone lit - indicating that the copy
operation is complete. Only then should you unplug the USB cable – wait 5 seconds then plug
it in again to resume normal operation. The Killamix Mini will now use the upgraded firmware.
You can if you wish check for the new firmware version number (see section above).
If anything goes wrong with the upgrade process, for example the SysEx dump file was
corrupt, or the wrong number of bytes were received, then the process will abort. See error
states below. The following LEDs indicate the status of the upgrade procedure:
123
Firmware upgrade mode (moves onto one of next steps too fast to see this)
1234 Download area for upgrade not blank (error state) – see error #4 info below.
12345 Ready to receive SysEx dump file.
123456 Correct SysEx file dump header identified – waiting for rest of file.
1234567 Checksum failed (error state) – see error #7 info below.
12345678 Complete dump received – will then be checksum checked.
123456789 Complete dump received – checksum OK – ready for button #9 press.
9 only
Indicates that the copy procedure is complete, you can now unplug.
Error state #4 – this will only occur if an incomplete SysEx dump file has previously been
received. The download area will now be erased but you will have to unplug the USB cable
and start again.
Error state #7 – this means that a complete file has been received, but that the file is corrupt.
The download area will be erased but you will have to unplug the USB cable and start again.
If LEDs 12345 remain lit when you have sent the dump, this indicates that no valid dump has
actually been received. Check you have selected the correct port settings on the computer.
Wait 10 seconds in case there is a delay in sending from your computer, then unplug the USB
cable and start again.
If LEDs 123456 remain lit when you have sent the dump, this indicates that an incomplete
dump has been received. Wait 10 seconds in case there is a delay in sending from your
computer, then unplug the USB cable and start again. You will probably end up with error state
#4 at the restart (see above).
Extremely important note
When the SysEx dump file has been successfully received, the checksum verified, and you
have pressed button #9 to confirm upgrade, then the old operating system is erased and the
new one copied to the operational area – this only takes about 1 second, but it is absolutely
essential that power to the unit is maintained during this copy period . For this reason
