    What baud rate are you communicating at? What feedrate are you programming? How long are the line segments you are interpolating? Sounds like the baud rate is too low for the feedrate you have programmed.

    I'm not familiar with the Meldas 310, but I'm pretty sure there is no such baud rate. 110,300,600,1200,2400,4800,9600 are all pretty standard, but 1240?

    I'm also not familiar with Cimco Edit's DNC settings, but check to see if there's either "Character Send Delay", or "Line Send Delay" or anything like that that could be slowing the transmission down.

    dnc

    sory for this typing ignore . 1200 is true . and i can find these parameters in cimco :

    delay befor each line
    handshake timeout
    breack after receiving character

    are these useful for our problem ? and do you have any good suggest for adjust this parameter ?
    do you have any good software for dnc ?


    and say again tanke you for your help

    Delay Before Each Line sounds like the one. If it's not already, try setting that to 0.

    I'm confused... is your baud rate set to 1200 or 9600? If it's 1200, bump it up to 4800 or 9600. If it's 9600, bump it up to 19200. If your cable is good, and the handshaking is working properly, you shouldn't get overflows.

    handshake timeout

    Go to your Parameters - in/out screen and see what the handshake time out setting is. I know Mitsubishi lets you set this. Bump it up to 200 seconds to see if this helps. check out www.meau.com

    mostafabagheri,

    I checked the Cimco Edit V5 documentation, and the only thing I see that could slow the transmission is the Delay Before Each Line. Did you check to see if that's set that to 0 yet?

    Mitsubishi up/download

    Hutch o7,
    I recently aquired 2 Machning centers with Mitsu MO controls. I use Hyperterm in windows for sending/receiving files. I am running that at 19.2 and with a 50 msec. line delay, it feeds faster error free than at 9600 with no line delay.
    I messed around for a while trying different settings until I got it right. If you are still having trouble let me know and I will send you the settings I use.

    Better you can use micro dnc unit for transferring the program, that will save the space and accurate data transfer
