You will need this specific connection cable to connect the GNSS receiver to a serial port. It is connected to the power supply using the PS2 socket of the notebook, tablet PC etc. The PS2 connection is purely a power connection and does not carry any data channels. The data protocol is provided via the SUB-D9 plug.
