Review: Worked perfectly when others didn't - I used this to interface the spindle on my CNC with the control software. I had tried a different one which didn't work, so I ordered this one to give it another try, and it worked perfectly. Used with a Chinese HY VFD and Mach3 software
Review: Este producto fue muy fácil de configurar y usar. Además de su actualización de drivers automática. Lo uso en la configuración de equipos con mod bus interface. Totalmente recomendado.
