I have an old KIA turn15 w/ Yasnac control. I am trying to download programs to a shop floor computer via RS232 cable. I have the manual BUT it is so difficult to understand/read, I cannot get the settings correct on the computer to be able to send and receive. I am using the DNC function on the editor with my SurfCam. I get a response on the screen while trying to download to the computer, but programs are not downloaded. Any help?
