Darebee, looks like you do not like to read online help: 1) To assign com ports to machine: Configuration -> Hardware -> Number Ports, restart software Configuration -> Hardware -> [Configuration] Assign COM ports to machines, done. 2) Close Software. This software is used by quite large companies. The operators are at the machine. Simistornij regulyator napryazheniya dlya induktivnoj nagruzki. They fetch their NC Files via remote commands.

Imagine: Someone switches off the software and the machine operators try and try. You can change this behaviour via the security configuration!

Simon cnc services can support you with Program 'Back up' using the DNC Data. The software V24 Link supports you with the administration of CNC. Port (PCI) for a multiserial card for interfacing up to 32 machines. A free USB port.

Drip feed with microsoft terminal??? You mean hyperterminal?

I use it to transfer cnc files by rs-232 serial port. What parameters or how do you get it to drip feed? Do you just slow baud rate? Or use software or hardware handshaking?

Forgive me for asking, i have never tried DNCI used three wires and Xon Xoff communication. I had to set the machine then go to the computer and start feeding the program. I think I was using 4800 Baud. Actually it's the old 'TERMINAL' program, Before Hyper terminal. I confess I didn't figure it out in Hyper. So I don't know how it works there. Back in the day of Windows 3.1.

Waaaay back, I have a copy and how to set it up if your interested. You will want do do some simple tricks to make it comfortable to use; but it does a smooth job. When I was using two iterations of it, one for each machine I was worried what might happen if both machines needed 'code' at the same time. You could watch it stair step up alternating between machines. In 2.5D machining there is time between commands as you mill the side of a part (for instance) which gives plenty of time for Terminal to feed the other machine. I used to run both machines and play Solitare at the same time on an old 286 computer. When the machines needed 'code' the Solitare card being flipped would hang in the air until the machine was fed.

Fun to watch. Thank you for DNC info Xon and Xoff so when machine is ready for more CNC sends ok to send more every so many bits or bytes and computer sends it til given signal to stop. Same as 2 computers sending a file from one to another. Microsoft Terminal I would have to find old Win3.1 computer.

Hyperterminal works although sometimes it malfunctions (not sure why) and computer needs restart. I have other software that came with mastercam for rs-232 sending files. It might DNC if I set Xon and Xoff software flow control. Mastercam software has built in text editor.

I send file to CNC and send it back to computer to see if 'translation' by CNC is ok(edit if needed). Then i send it back to CNC.

So on some machines that use no flow control DNC would not work, but newer machines that use software flow control (handshaking) might be able to DNC. Prototrak Plus mill has no rs-232 flow control. But Prototrak AGE mill I think might have it so maybe can do DNC. This would be useful as Prototrak has memory or file size limit of about 20kb or 330 lines of gcode. Thank you I will try DNC.
