The universal pendant mount USBCNC-SW allows for easy upload and download of CNC g code files to just about any control. DNC functionality is built in for programs that exceed the internal memory size of a machine tool. The USBCNC-SW features automatic electronic switch box functionality. One of the RS-232 ports connects the CNC’s serial port in stand by mode. The USBCNC-SW does not interfere with serial communication with the PC and the CNC’s serial port.
When the USB functionality is activated by using the keypad, the USBCNC-SW switches off that connection and communicates to the CNC with files on a USB flask disk. Once complete, control is transferred automatically back to the PC connection. This features is useful for applications in which a CNC can have connection to a PC or a Calmotion USB controller.
