OMC-140 Installation Manual Page 28
Q Baro Status (AUTO)
Z NMEA Allow No Checksum (OFF) Port 1 & 2
Once finished leave the menu and save the changes (type 0 until you are asked to save / discard
settings, then choose 1 to save).
If you open the ‘Front’ tab now you should be able to toggle through the parameters corresponding the
enabled data.
Once finished use ‘Save & Exit’ to store your layout.
If you enabled the correct data messages for the correct Sensor ports you are done. But if you are not
sure to which Sensor port the data will be sent you will have to change all Data messages set to ‘On’
back to ‘Auto’ to be save. The display monitors for the expected data and will give a Sensor 1 or 2
warning whenever
expected data (=data set to ‘On’) is missing.
6.4.5 MeteoLink and OMC-140
With the introduction of MeteoLink, Observator Instruments introduced the option to identify the origin of
a sentence in the system by adding a (NMEA compliant) tag in front of the sentence. This way multiple
wind sensors all transmitting MWV messages can be identified in one stream, so up to 4 wind sensors
can be connected to the display via 1 NMEA cable (or UDP). It will also allow this for other sentences.
There is only a selection button available for wind sensors. But you could display multiple temperature
sensors for example.
It does make some things a little more complex. The OMC-140 is default set to auto configure and will
recognize incoming sentences, add them to the input list including the tag id. The display will monitor the
input and warn if messages are missing.
The list for MWV & XDR id’s is limited to 15, if the list is full, no sensors will be added!
This is more than enough for any system, but could lead to issues if you make changes to a system.
You should realize identical sentences with different tag id, are not identical sentences for the display.
For example: if you would replace an OIC-406 temperature Humidity sensor without any changes to the
display configuration, you will have 2 temperature and humidity parameters in your system.
You will notice no temperature & humidity will be displayed, since the OMC-140 display expects data
with the ‘old’ tag id!
To solve this there are several options:
1. Factory reset and (re)configure the display completely
2. Remove unused NMEA sentences (Advanced user login, then Tab NMEA )
Reconfigure temperature & humidity in ‘Front’
Option 1:
This is easy: via Touchscreen go to advanced and use code 0852984.
Downside is you will have to do the complete configuration again (but usually it doesn’t take
much time)
Option 2:
Via Touchscreen go to advanced and login in with 1382
Go to the NMEA tab and check Inc. Sentences under Configuration is set to ‘unlock’
Tap on ‘Clear missing’ (under Incoming Sentences) and again when it pops up large.
Save & exit
Log
in again with 1382 and configure the ‘new’ temperature & humidity
It is recommended to start with an empty list before you make a new configuration!
