The USB Connect Pendant controller for all CNC’s with any DNC System is a CNC Switch box USB specific model. Provides automatic switch box functions to keep serial port active without interference from USB controls when connected to DNC systems.  Includes 8GB USB Flash Drive, panel-mount  USB connector/waterproof cap, display, USB cable, & power cable.  Powers by 7-28vDC from CNC.

Our USB Connect device acts as an interface between commercially available USB flash memory and any CNC control with an available RS232 port. Machine tool files can be sent from CNC memory to the USB key, USB key to CNC memory or drip-fed (DNC) from the USB key. Flexible DNC firmware is built into the USB Connect unit allowing connection to just about any machine tool CNC control. The pendant mount USB controller kit contains all the necessary hardware to integrate a universal display onto a CNC machine tool pendant.

Increase program storage at the machine with this device. Drip-feed your large files from your memory device or DNC. It is also worth noting you do not need a CNC software or hardware update in order to use this device!
