NMEA Multiplexer with bidirectional SeaTalk and USB Port

The gadgetPool NMEA & SeaTalk Multiplexer is a NMEA-Multiplexer with additional Seatalk port and USB-port.
With this NMEA-Multiplexer you can connect serveral NMEA devices, read data from a SeaTalk network, write Data to your Seatalk network and also connect your PC

  

Multiplexer ports :

  • 4 galvanic isolated NMEA 0183 inputs.
  • 2 NMEA 0183 outputs
  • 1 galvanic isolated SeaTalk port. SeaTalk Data are translated into NMEA sentences, NMEA Data are translated into Seatalk data
  • 1 USB port for PC. With the USB port, a PC can send and receive NMEA Data.

What is a Nmea-Multipelxer good for ?

NMEA devices can send data and/or receive data from other NMEA devices. .

According to NMEA standards, a sender can send it's data to up to 4 receivers.

For a receiver, It is not possible to receive data from more than one sender.
A NMEA receiver can only receive data from one other device at a time.
I.e. With one NMEA input port, a Chart plotter can not receive position from a GPS device and depth data from a depth sounder at the same time.

In order to be able to receive data from more than one NMEA source, a NMEA-Multiplexer has to be placed in between the senders and the receiver.

A NMEA-Multiplexer receives data on separated input ports from different NMEA devices.
It buffers this incoming data, filters them and sends them out well ordered to the receiver.

gadgetPool NMEA-Multiplexer can receive data from :

  • up to 4 NMEA devices ( i.e. GPS, depth sounder, wind instruments, AIS etc.. )
  • 1 board PC via USB
  • 1 SeaTalk network.

The Multiplexer buffers, filters and send this data in proper order to :

  • 1 board PC via USB
  • up to 4 different types of NMEA receivers
  • to the Seatalk network

Housing and terminals

Housing
The multiplexer comes in a nice and sturdy metal housing.
For easy installation and service, all terminals for NMEA, SeaTalk and power supply are detachable

NMEA inputs


NMEA outputs


Update : In the picture above only two NMEA out ports are shown. Meanwhile all 4 NMEA out ports are available.

SeaTalk connection

Currently the following NMEA sentences can be produced based on incoming SeaTalk data:

  • $IIDBT Depth
  • $IIVHW Speed through water
  • $IIMTW Water temperature
  • $IIVLW Total milage, trip milage
  • $IIMWV Wind direction and wind speed
  • $IIHDM Heading magnetic
  • $IIRMC Speed over ground,heading, longitude, latitude , time, date
    Optional an aditional $IIGLL sentence can be sent.
  • $IIRSA Rudder

Power supply

Technical data :

  • Operation voltage : 10-30 Volt DC.
  • Power consumption : 60 mA ( 100 mA max. at full load)
  • Inputs : 4 * NMEA-0183 ( RS-422 ) galvanic isolated
  • Outputs : 4 * NMEA-0183 ( RS-422 )
  • Network : 1 * SeaTalk in/output galvanic isolated
  • Baudrates : 1200 Baud - 38400 Baud ( USB up to 57600 Baud )
  • Memory : 2*4 kB Buffer for each NMEA channel. ( 4kB send/ 4kB receive)
  • PC-interface : 1 * USB virtual serial port for NMEA sending and receiving

Hello Frank Works as advertised. Thank you very much !!! One note: When you compile the source code on one machine and want to copy it to another you still need to install qt5 and the libraries but do not need to compile it again. I needed to change the file permission on the new device to allow execution: pi@raspberry:~ $ sudo chmod 0755 stConfig Obviously it needs to be executed in a graphical environment. Since I use my raspberry headless i was able to run it in a x11vnc session perfectly. Thank you again so much !!! Ralf

Hallo Auch wenn ich noch keine Erfahrungen mit QT5 gemacht habe kann ich gerne versuchen es mit den Sourcen zu compilieren. Gruss Ralf

Hallo, ich bin gerade dabei zu versuchen eine neue Version für den PI zu compilieren. Ist etwas aufwändiger. Ich habe hier mittlerweile QT5 installiert und nun muss ich schauen wie ich das zu einer lauffähigen Version mit allen benötigten Libraries packen kann. Alternativ - wenn die QT Entwicklungsumgebung installiert ist, sende ich gerne sie Sourcen. Gruss Frank

Hallo auch von mir ein riesiges Dankeschön für den gelungenen Muxxer. Ich betreibe ebenfalls den RPi 3 als Nav-Computer an Bord meines Segelbootes und würde diesen gerne zum Konfigurieren des Muxxers nutzen. Bei mir startet stConfigPi ebenfalls nicht. Im Desktop Mode tut sich gar nichts und im Terminal mode gibt es den folgenden Fehler: pi@raspberrypi:~ $ ./stConfigPi Segmentation fault Ich habe qt4 wie folgt installiert: pi@raspberrypi:~ $ sudo apt-get -y update pi@raspberrypi:~ $ sudo apt-get -y install qt4-default qt4-dev-tools qtcreator Da ich nicht weis welche libraries benötigt werden habe ich gesucht und die Folgenden installiert: libqt4-dbg libqt4-dbus libqt4-declarative libqt4-declarative-folderlistmodel libqt4-declarative-gestures libqt4-declarative-particles libqt4-declarative-shaders libqt4-designer libqt4-designer-dbg libqt4-dev libqt4-dev-bin libqt4-help libqt4-network libqt4-opengl libqt4-opengl-dev libqt4-phonon libqt4-ruby libqt4-script libqt4-script-dbg libqt4-scripttools libqt4-sql libqt4-sql-mysql libqt4-sql-odbc libqt4-sql-psql libqt4-sql-sqlite libqt4-sql-sqlite2 libqt4-sql-tds libqt4-svg libqt4-test libqt4-xml libqt4-xmlpatterns libqt4-xmlpatterns-dbg libqtassistantclient-dev libqtassistantclient4 libqtconnectivity1 libqtcontacts1 libqtcore4 libqtcore4-perl libqtcurve-utils2 libqtdbus4 libqtexengine-dev libqtexengine1 libqtfeedback1 libqtgallery1 libqtglib-2.0-0 libqtgstreamer-1.0-0 libqtgstreamer-dev libqtgstreamerui-1.0-0 libqtgstreamerutils-1.0-0 libqtgui4 libqtgui4-perl libqtkeychain1 libqtlocation1 libqtmessaging1 libqtmultimediakit1 libqtnetwork4-perl libqtorganizer1 libqtpublishsubscribe1 libqtruby4shared-dev libqtruby4shared2 libqtscript4-core libqtscript4-doc libqtscript4-gui libqtscript4-network libqtscript4-opengl libqtscript4-phonon libqtscript4-qtbindings libqtscript4-sql libqtscript4-svg libqtscript4-uitools libqtscript4-webkit libqtscript4-xml libqtscript4-xmlpatterns libqtsensors1 libqtserviceframework1 libqtsolutions-soap-2.7-1 libqtsysteminfo1 libqttest4-perl libqtversit1 libqtversitorganizer1 libqtwebkit-dev libqtwebkit-qmlwebkitplugin libqtwebkit4 libqtwebkit4-dbg libqtxdg0 libqtxdg0-dev libqtxml4-perl Ich habe auch versucht QT Creator nach folgender Anleitung abzusetzen: https://www.raspberrypi.org/forums/viewtopic.php?f=31&t=43545 Aber stConfigPi ist ja schon compiliert und sollte im Desktop Modus nativ laufen, korrekt? Ich wäre Ihnen dankbar, wenn sie die Benutzung des Raspberry Pi Config Tools noch kurz erklären könnten. Vielen Dank für Ihre Unterstützung Ralf

Nema Bridge to Wifi to IPAD

Hi I have just completed interfacing the SeaTalk NMEA Bridge128SD with a USR=WIFI module to stream the data on WiFi via the RS232 port. I do all my offshore navigation on an IPAD but then discovered not many racing Apps use wifi, most use bluetooth. I was considering this when I came across an interesting page on Zifigo who make Iregatta offering a limited number of beta test vesions. http://www.zifigo.com/?q=node/666 Looks like an app is on the way, I am hopeful of getting one to evaluate. Maybe some other yacht racing members may find this link interesting. The SeaTalk NMEA Bridge128SD is a well made solution. I am looking forward to playing with it and the race info it provides. Best regards

I can't download the latest firmaware version
Well - I just tried it again and it worked for me. If you still have problems to get, just send me a mail and I can sent it to you. Frank

Thank you but I've not receive your mail Can you send it again ?

Apparently this did not ever make it into a product. I'd still be interested in one, so any other advice or pointers? Thanks, Harri
