    DNC Help Please on VMC15

    I have an older 93 VMC15 with 1400-4 cards.. so, this makes it at early 96 firmware.

    I have been trying to get the DNC working. I have finally out grown my little memory area.

    I can load the smaller programs to the machine with Cimco V5 and even ConnectCNC.. I put in the TA,1 and we have great communication..

    However when I go to DNC, I get some strange things.

    Cimco will start to load the program and get to line 320, and the Fadal screen shows it just stops taking any more lines of code.

    ConnectCNC will start to load the program and get to line 290 of the same above program and the Fadal screen shows it stops taking lines of code there.

    I dont get any errors displayed.. it just stops taking lines of code.

    If I start to play with the parity, I start to get errors. If I change the baud rate from 9600, neither program will work. It seems that 9600 is the only setting that wants to work. I dont understand why 4800 wont work really on transferring a program, but it will not.

    I am starting to think I have a bad communication card in the machine, but maybe it is just a software setting.

    here is the few lines of code it is taking via DNC.. if I cut this program to line 5000, I can load it fine and run it as a resident program on the machine.

    It sounds to me like your send settings need to be tweaked.
    I suggest you set send type to line and not to buffer.
    I haven't touched my settings for a few years, so my memory may be off.
    I DNC to my 94 fadal at 19200 baud.
    You have to change the SetP parameter (for baud) and then power down the machine (once you are back to the MDI screen) for it to take.
    I find 9600 baud really starves the control when you have really small moves like when "surfacing"
