Customer FAQ

Q 1 .   What's the way of connecting the rs232 port to raspberry pi, I suppose that is using the GPIO pins, is that right?
Answer: No. It’s connecting the RS232 port to Raspberry Pi through USB port. The two RS232 serial ports are USB to Serial bridges. The configuration is like USB -> USB Hub -> USB-to-Serial Bridge + USB ports. It connects directly to the USB output port of the Pi. If you are looking for RS232 serial using GPIO pins, the PI232DB9M is the right solution. http://ableconn.com/products_2.php?gid=30
