I bought an rs232 usb cable off trademe, as my laptop does not have an rs232 port and my satellite receiver does not have an ethernet port. This cable has a usb plug on one end, and male rs232 on the other. The problem is that my satellite receiver, also has male rs232. So I bought a female/female adapter, to allow the two males to join. But I get nothing from the satellite receiver.
Am I doing this wrong? Do I need to take another approach?
