10.1.3 TAG notes
Observator MeteoLink and the Observator OMC-140 make use of (NMEA) Tags, which are placed in
front of the basic NMEA senstence to identify the source of the sentence.
This enables the use of multiple simular sensors with identical NMEA sentence ID.
For example multiple wind sensors all transmitting $WIMWV sentences multiplexed in one stream can
still be identified, while without a tag the display would process them as data from 1 sensor.
The TAG “\s:string*hh\” can contains source information of the string.
‘string’ starts with a letter (A= SMART node, B= Basic node & D=OMC-140 Display), followed by the last
three digits of its serial number, followed by the input port.
Examples:
A sensor connected to NMEA 1 port of a SMART node with serial number: OICA-000123 shall result in:
\s:A123P1*hh\
A sensor connected to NMEA 2 port of a Basic node with serial number: OICA-000223 shall result in:
\s:B223P2*hh\
A sensor connected to NMEA 1 port of an OMC-140 with serial number: 1400001203 shall result in:
\s:D203P1*hh\
3rd party equipment designed according the NMEA 0183 standard, will ignore the TAG data
if it has no use for it.
For non compliant equipment the tag data can be disabled via the USB menu:
1. Device settings / 4. Output / 8. Node Info Pass Through
Starting from FW version 2.6 the tag data of the OMC-140 is default disabled on the NMEA output
port (enable via the same USB menu).
