2. Setting the Miniplex2-Wi

MPX-Config allows you to adjust the input / output NMEA ports. Mainly IN1 port rate is set at 38400 bps to connect the AIS. IN2 and IN3 ports at 4800 bps for other devices (GPS, Nav Center NMEA 0183). IN4 port can be used to connect a Raymarine SeaTalk network, in this case from the dropdown field Input Mode select «SeaTalk». The data is then translated into NMEA sentences.

Out1 port is generally used for the autopilot. iNavX uses to send NMEA data in order to run autopilot in "Navigation" mode. The Out2 port is used for other instruments (Repeater, chartplotter). Warning, if AIS data are sent to, it will adjust the minimum 38400 bps, or more to avoid overflow, this means saturation of the received data and lock the multiplexer working.

A detailed leaflet of 44 French pages allows a more complex configuration. It is available for download at the top of the page Downloads : some advanced features are used with caution being sure to carefully control what you do, avoid especially go fiddling around in the last tab filters.

    Through a few sentences, I guess this device is not the dishes but must be used to transmit data from navigation devices to an iPad or iPhone on board.
    I still do not see the point and yet there must be a ?
    When that computer specialists speak plain? En Français Normal… just for the boater that I am. Boater on a catamaran Mahe 36, yet I am equipped with hardware and user Furuno autopilot, a sounder, a card reader, an anemometer, of a weather vane with repeater, d'a Macintosh, d’un iPad , Navionics charts on iPad, et the Weather 4Dpro. But here I am overwhelmed, article incompréhensible .
    Multiplexer, firmware, driver, NMEA, Router, FTP, port IN1, bps, this would not talk to me…au secours Francis.
