Communication Settings

Settings:
You can have any number of different machines with custom settings. Choose the machine you want to change in the Machine dropdown box.

Then click on Settings - Communication... on the main menu and the settings window of the current machine will be displayed..
 

General Settings:

Serial Format

Check your control documentation for setting these items.
Longer wiring requires lower speeds.

This system relies on the machine control sending a signal to DNC Server when it is ready to receive ("X-ON" or CTS) which most all CNCs would do.

To bypass this and send out a file immediately when pressing the Send button, you would leave this unchecked.

All of these settings are stored in the file DNC.INI under the individual machine. 

Files

Default Read Directory - Directory that shows up in the left directory list when you choose a machine from the drop down Machine list.

Default Save Directory -Directory that shows up in the when you save from the edit window.

Strip Comments When Sending- If this is checked, DNCServer will strip out comments when sending. This is handy for the machines that don't accept comments. Set the beginning and and comment characters to look for. For instance, for Fanuc controls "(" would be the start comment character, and ")" would be the end comment character. If a only a single character is used at the beginning, like "!" to designate a comment, put it in the Start Comment Char and leave the End Comment Char blank, and everything from the start comment char to the end of the line will be stripped out.

Send Extra Characters : You have the option of sending extra characters the control might need at the beginning and end of the file. Special characters can be sent by using the ascii value enclosed in left and right arrows. For example, to send an extra carriage return at the end you would would type in <13> in the box. Your control may need Null characters at the begining or end of the program (like blank leader on a tape). A section of blank tape (feed holes) can be simulated by a series of zero values: <0><0><0><0><0><0><0>. Fanuc controls usually need end of file character: <20>.

Strip Blank Lines -If this is checked, blank lines will be ignored when both receiving and sending files.

Strip Characters : You have the option of stripping any characters that the control might send. Special characters can be stripped by using the ascii value enclosed in left and right arrows. These characters will be stripped at send and receive. Use left and right arrows around the decimal numeric value of special characters, as in <59>.

Char Delay  Keep at 0 unless you have special circumstances where there is no handshaking and you need to slow the pace down to not loose any characters.

Default File Extension - Used for display of files in the open and save dialogs. Change to .* to display all files. Also used with Auto-Save and Receive when no extension is supplied.

---

End Receive File On   - DNCServer automatically looks for these control codes in the files it receives. It stops receiving the file from the control and closes the file when it receives any of these control codes: #20 (DC4) or #3 (ETX) or #4 (EOT). or when it receives a second "%" character. If your control doesn't send these codes, you can set DNC Server to stop receiving when it receives a certain string of characters. You could enter "M30" in this box and file receiving would end when this was found. 

Add After Sending a File   - Most of the time you want to send character #20 to the control to tell it that it is finished sending the file. You can send any other characters in the Machine page.
