Review on Cable Matters Serial Adapter RS232 by Brian Schultz

I use it to run an old computer controlled radio. (PCR-1000) Using Windows 7 and quick installation of the adapter driver. Pay attention to the communication port assigned to it, it is initially set to 11. You can easily change it in Device Manager. Choose the advanced option and select the mapping number required for your device. I switched mine to com port 2. The radio worked right away. So far it has been very reliable. Also, if you change the USB ports, the driver will reinstall and reassign port 11
