NMEA 0183
The GNSS Compass supports outputting the version 4.10 compliant NMEA 0183 messages over both Serial and Ethernet connections.
For the serial variant (GC2-SER):
-
Serial data is output on the Auxiliary serial port.
-
Each message can be enabled or disabled and output rates are configurable.
For the Ethernet variant (GC2-POE):
-
Ethernet messages are enabled by default, however can be selectively disabled.
-
NMEA 0183 broadcast packets are sent via multicast to IP address 239.192.0.4.
-
These are sent whenever an Ethernet connection is established and cannot be disabled.
The minimum rate is 1 Hz, except for GPHBT & TSS1 whereby the minimum is as indicated in the table NMEA 0183 output messages supported.
The maximum output rate for any message is 50 Hz.
The NMEA 0183 messages are:
