    Why have an NMEA multiplexer?

    Electronic help in navigation is becoming more and more common on boats. Fishermen and competitors can no longer sail without it. Portable computers are genaraly found on board small and medium ships. Marine navigation software that used to be available only to professionals is now available to all in order to use all information coming from instruments. Liesure boats now have access to routing functions as well as establishing polars for a safe and controlled navigation. These programs recive information from only one communication port, the most important being the GPS signal. On board electronics are also sources of NMEA data such as the log, anemometer, wind vane, depth sounder, compass, etc.

    The NMEA transmitor can aslo be used without necessarily being connected to a computer as when more than 2 NMEA sources are transmitted to the the auto pilot. It can combine different brand instruments for the NMEA protocol is standarized for all developers.

  • PCI Cards

    The difference between "H" serial cards and "L" serial cards.

    "H" serial cards work with a communication protocol "128 Byte FIFO", whereas "L" serial cards work with a communication protocol "16 Byte FIFO".

    The FIFO (First In, First Out) manages a waiting line (priority system in which the first objet available was the first object placed).

    So the only difference between FIFO 16 BYTE and FIFO 128 BYTE is speed.

    U-PCI cards consume between 3,3V and 5V whereas PCI cards consume 5V.
