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 :
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 :
The Multiplexer buffers, filters and send this data in proper order to :
Update : In the picture above only two NMEA out ports are shown. Meanwhile all 4 NMEA out ports are available.
Currently the following NMEA sentences can be produced based on incoming SeaTalk data:
