The USB Connect Portable is a communication device that can be used to load and save programs from your CNC Memory and Drip-Feed to most CNC Machines. The USB Connect contains its own DNC firmware and requires no other device or components to work. Because this portable DNC device for CNC machine is not dedicated to one machine, it is the ultimate DNC transfer box standalone solution.

This solution is a great device to back up your DNC Network for when it goes down or to be used as the primary input device in your CNC shop. It supports the high-speed baud rates that HAAS and FADAL controls using Xmodem, plus the USB Connect will work on most CNC controls that support standard serial protocols.

Drip-feed (DNC) large files from the USB Connect is simple. You do not need a CNC software or special cables in order to use this device.  Simply connect the unit, select DNC and press cycle start on your CNC.  Keep in mind, your controller must support this capability.  If your unsure, send us a quick email or give us a call.

-Randy, Fredon Corporation

“They asked me to check if it’s possible to generate programs in 3D CAD software and transfer it directly to the machine…I found a simple device that handles the communication with the CNC machine over the RS232 port and reads/writes to USB.”
