Add USB or Ethernet to Your CNC

The USB LAN Connect solutions will eliminate old technology on your CNC machines, increase program storage at the machine, & bring new life to them with our USB solutions. Tired of CNCs with a floppy disk drive? Are you looking to add a USB port or Ethernet to your CNC control to transfer NC programs? Our solutions, available in portable & pendant models, streamline the loading & saving of part programs and can drip-feeding to CNCs.

Our Floppy to USB Emulator acts as a floppy disk drive for machines, is easy to install, and requires no system configuration/debugging. It works on PCs and an extensive list of CNC machines. Call SFA at (877) 611-5825 with your floppy drive Make and model info so we can confirm the ability to emulate!

Installing the USB Connect controller close to the control allows the machine to run at its maximum baud rate. This also adds extra protection from potential damage and saves the operator time running from the PC to the machine to begin operation, as the device will push files to CNC machines.

Store large part program libraries on a single USB flash drive to achieve controllers-to-USB drip-feeding. Enjoy hardware and software flow control, plus Xmodem flow control. Our USB LAN Connect solutions also address Haas USB and Haas RS232 needs!
