    XYZ Vulcan Meldas DNC... HOW?

    Hi Guys,
    Trying to get drip feeding to work, but I don't have anyone in the real world to ask, and basic instructions online are scarce, so I'd appreciate a hand!
    I've got upload/download to work, so I thought great, set the tape device to the same as the input/output device in the I/O parameter, go to tape mode, type program number, send from pc, press input, easy money. Not so.
    I've tried this, it just says 'not found', I've also tried dev(1) as well as dev(0).
    Could you tell me where I can find, or tell me, the basic instructions to get this to work, so I can work out if its a parameter setting or if I'm just doing it wrong.
    Many thanks!

    CNC Parameters
    On the RS232 parameter page, choose the device column you
    are going to use for your PC and make sure the following
    settings apply:
    2 to 2 - 4800 (baud)
    3 to 1 (1 stop bit)
    4 to 0 (no parity)
    5 to 1 (even parity)
    6 to 3 (8 data bits)
    7 to 5 (any two characters ends transmission)
    11 to 3 (DC Codes)
    12 to 0 (no DC Code Parity)
    13 to 3 (DC2/DC4 output)
    14 to 1 (CR output)
    15 to 0 (ISO output)
    18 to 0 (no vertical parity check)
    (note: The Mitsubishi Meldas can appear deceiving. The
    parameters will appear not to match between the PC and CNC.
    This is expected)
    PC DNC Settings
    Baud: 4800
    Code: 7 data bits / ASCII Even
    Stop Bits: 1
    EOB: CR/LF
    Handshaking: XON/XOFF
    ADVANCED
    Leader: %CRLF
    Trailer: %
    Skip lines which contain: %
    Additional Notes
    Make sure that when you perform a transfer, you are set to
    transfer on the device number which matches the column you
    set your parameters in.

    HOW TO STOP MITSUBISHI FROM STRIPPING SPACES ON
    INPUT/OUTPUT
    SET BIT 6 OF mpar1 TO 1 (VALID)
    SEE PAGE App 1-11 (APPENDIX 1, PAGE 11)
    BIT 6 ON THAT PAGE SAYS "WORK PROGRAM SPACE IS
    ENABLED"
    PARAMATER IS IN BASE SPEC PARAMATERS. NAMED mpar1
    WILL STILL STRIP SPACES FROM THE COMMENT ON THE OPROGRAM-NUMBER LINE

    Thanks guhl.
    I dont think this is the problem. I can send programs to memory, just not drip feed them. It just says program not found.
