Cable Pin Out

Cable pinout for connecting Fanuc CNC

Sometimes file transfer will not run, even if all the settings are correct.
The following procedure may correct the problem, especially if you're running the machine via DNC:
Check to make sure your FIFO buffers disabled on the PC.
You access the settings in Control Panel -> System -> Hardware tab -> Device Manager.
Find your COM ports and double click the one you are communicating with.
Click the tab for Port Settings then Advanced. Uncheck the FIFO buffers.
Having this turned on can cause problems with RS232 transfer, especially DNC.
Once you have ConnectCNC and your CNC machines communicating, we strongly suggest you take the following precautions:
- Download some programs, the longer the better, from your CNC to the pc. Save them under a temporary filename so you don't overwrite the original files. Examine them for errors such as dropped or changed text.
Do this for the first few programs that you use.

These settings have been collected from users of our software and machine tool distributers. We have listed them to help users of ConnectCNC to communicate between their computers and CNC controls.
Since we have no control over the many variables involved, including such things as cable conditions, modifications to machines, condition of computer hardware, etc., we take no responsibility for any damage caused to programs or machines through the use of this software.
