Does anyone know if you can get cables for a USB to RS232 connection for PC to CNC connection? I did some research and see that there is a cable like that. I just wanted to know if it is possible before I buy anything. I currently have a DB9 to a DB25 and did the pinout for proper connection. If it is possible is there a different pinout for doing this vs. a standard CNC 9pin to 25 pin connection? Any downside to this? Any recommendations on were to get this would be helpful. Would RadioShack carry something like this?
