MCT U232 P9 is one of a few usb to serail adapters which converts USB +/-5v voltage levels to COM +/-15 voltages. So it can also power COM interfaced devices. This makes it very usable for legacy COM interfaced data-acquisition hardware. I tested new implementation with AWARE Electronics RM-60 radiation meter, which sends pulse via RNG COM line whenever new particle is registered.
