Navilock GPS PDA receivers have an MD6 universal connector. The connection assignment of this connector is identical for the U-blox, Sony, GLONASS and SiRF chipsets. To connect the GPS receiver to a serial port, you need this specific connection cable. It is connected to the power supply with the PS2 socket of the Notebook, tablet PC or similar. The PS2 connection is a pure power connection and does not route any data channels. The data protocol is made available via the SUB-D9 connector.
