NMEA 0183 over UDP
The LT-4200 system supports transmission of NMEA 0183 sentences (GNSS position information) via the
LAN interface. The supported protocol is UDP (only broadcast).
The IP destination address will always be the local broadcast address of the LAN. I.e., if the configured LAN
network address/mask is 192.168.1.0/24 the destination address will be 192.168.1.255.
The UDP destination port is user configurable, see Table 22.
The configuration of the NMEA 0183 over UDP is illustrated in section
on page 99. The
Talker ID of the NMEA 0183 sentences can be changed by changing the configuration of the GNSS Receiver.
NOTE
:
Currently it is only possible to send NMEA 0183 sentences (GNSS position information) on
one interface at a time. I.e., selecting CU LAN will disable GNSS on the RS-422 interface and
vice versa.
