Buffer Size:
The input and output serial buffer size can be
changed. This does not normally need to be changed.
Output Method:
"Send by Char" sends one character at a time
to the CNC control and checks for handshaking between each character.
This is the safest method.
"Send by Line" sends a whole line at a time to the CNC before checking
for handshaking. This uses less processor resources. Needed if you want
to run other programs while sending a file. This could speed up the
sending of programs to the CNC at higher baud rates. Older CNC controls
may not be able to handle this.
Use Subprograms - DNC Server can use Fanuc type subprogram calls when it sends a program to the machine. If this is on, when DNC Server is sending the program, and when it hits a line that has "M98P1111" in it, it will:
- run normally until it hits the line with "M98P1111". Where P1111 is whatever program number to call.
- look through the entire edit window and look for the start of that program. O1111 or :1111
- jump to the next line after that program number.
- continue sending the lines until it hits a line with "M99" in it.
- jumps back in the editor to the line after the original "M98"
- continues sending lines until the next "M98
Maximum sub levels is 5.
The main program and all the subprograms have to be in the editor at
once.
Put the main program at the top of the editor. Put "M30" at the end of
the main program. DNC Server will stop sending when it hits "M30" or the
end of the file.
With this, you could drip feed to a machine a program that had
subprograms.

USB Serial Adapter:
Somtimes when using a USB to Serial converter, the handshaking doesn't get through the converter fast enough, and there can be a buffer overflow error at the CNC control. Try setting the Windows serial buffers as small as posible. Do this by going to: Start Menu - right click on My Computer - Properties.
Hardware Page:
Right click on the communication port.
Port Settings Tab. Advanced Button:Move the buffer trackbars all the way over to the left.
