Can a keyboard be used with the DPO3000/MSO3000?

Yes, for USB keyboard support for editing labels and file names.   No other functions are supported.  The keyboard ENTER does not work, only allows for the typing of the file name. The Accept must still be done from the front panel.   Left and right arrows allow for selection of the character to be edited.
