I know enough to be dangerous. I am presently fooling around with remote (CAT) rig control. Got the FT-991A working great via USB/USB. I want to do a similar thing with the FT-450D. That will be RS-232/USB. I have a 232/USB converter (D9 to USB) and it is supposed to be the good type (FDHI...FHDI>>>??? you know...NOT the Prolific). My question (and I do have one) is: I received a "Driver" DVD (the mini ones) with the converter. It says nothing except "Driver". Do I need this on the computer (the converter actually will be plugged in to the FT450 serial port)...or can I ignore any additional driver requirement? I wasn't aware that any driver had to be installed for the converter to function. Whew...Thanks!
