1.2.5 Filtering sentences
The Smart Dongle allows you to filter the input NMEA 0183 sentences in such a way as to display and
multiplexed together only what is needed.
NMEA 2000 messages (PGN’s) are translated into NMEA 0183
sentences and vice versa. Therefore the filter feature of the multiplexer still works on NMEA 2000 messages,
NMEA 2000 PGN’s are first converted into NMEA 0183 sentences and then filtering and routing is applied.
First the sentence must be acquired in capture mode by pressing the Capture button. With this functionality
the configurator starts listening for 20 seconds (you can also block previously pressing the same button again)
of incoming NMEA sentences on Wi-Fi.
After the capture process is finish all the sentence are displayed in the
filter table as show in the following picture. Sentences could be removed by selecting the sentences and
pressing the Remove Rule/s button. All rules coud be removed by pressing the Remove All button.
The first coloum T.ID in the filter field is the talker identifier the second field Sent.ID is the sentence identifier,
follows the input ports, the division factor and the output ports.
Then check boxes in the green fileld show on wich input the sentence was acquired, where NMEA 0183 input
ports are In1, In2, In3 and In4, the GPS port (depend on dongle type) and the NMEA 2000 translated
messages virtual port N2K. If the input check box is selected the input will be processed by the dongle if not
the sentence will be ignored.
The check box in the red field allows to select wich sentences will be routed to the
NMEA 0183 output (Out
0183), NMEA 2000 output (Out N2K) and WiFi output (Out WiFi). To the NMEA 2000 output is possible to to
route (translate) only sentence from the NMEA 0183 ports.
