Hello all. I have to connect to a Siemens S7-200 CPU 224-XP using a serial connection with DB9 to USB converter. The converter is connected and, according to device manager, all is well. I am using Step 7 Micro/Win so that I can upload what is currently running in the CPU however, it keeps saying "Specified access point not found". I haven't connected to one of these for about 12 years so I don't remember what step I am missing. I have a line down and called tech support however, they want $330 to help me with this legacy junk. I am sure hoping someone here can help. Thank you
