So I just dug up this other thread about the USB and serial cable issues and USCutter support says flat out that the USB to Serial adapters will not work. Like JayDadd101 suggested, they only "carry" Keyspan as they have tested them thoroughly.
I shopped around on USCutter and they sell a USB to Serial RS232 Adapter FTDI Chipset Cable. Immediate issue here, besides being shorter than a toddlers arm, is that it isn't Keyspan?!
They also have these Graphtec 10ft 9-25 Pin Serial RS 232 C Cables.
I should mention that the original USB cord that came with the SC Series cutter did work for a couple of months. However, all along It gave me many warning signs with a number of issues like not responding to the software when trying to send a cut or not finishing a cut it had started.
Any response is greatly appreciated!
