I am having Toshiba laptop without com port. Only USB port. Want to down load program from Laptop using serial USB converter. Tried but not succeeded for FX3U80M using Gx developer. But succeeded to down load E300 using E-designer.

So help me to solve how to download using GXdeveloper?USB serial converter working with E-designer.

 

Hi,

I have experienced similliar problem using usb to serial converter. Usb to serial converters use different chips and some converters will work in some applications and not work in other. I would suggest to buy a new and test. In my experince, Manhattan usb to serial works with most applications.

Best regards
