3 Data log function
3.1 Introduction
In firmware version 1.00B22 the data log function is included. From this version and up all relevant data
can be logged on a Micro SD card and will be stored per day in .txt files.
The format is compatible with the Observator data loggers and can be read by OMC-Data-Online or
imported in for example Microsoft Excel.
3.2 Data log function settings
The data log function can be enabled using the USB menu, for USB menu connection details see OMC-
140 installation manual.
All log related functions are in the menu 5 SD Log Settings.
1. SD logging On or Off
2. Storage interval 10 minute, 2 minute or 5 second interval
3. Set Date Option to correct the date
Format: =yy/mm/dd (the ‘=’must be included!)
4. Set Time GMT Option to correct the time:
Format: =hh:mm:ss (the ‘=’ must be included!)
* GPS message at noon (if available)
* Once SD logging is selected On GGA message is available; time will be daily synchronized with the
UTC time. Since date is not in the GGA message this will not be synchronized like the time!

3.3 Storage
Once an SD card is inserted and the SD logging function is set On in the USB menu, data will be logged.
All relevant NMEA received data will be stored, see paragraph 3.6 Parameters for more details.
The storage interval can be selected in the USB menu only (changing interval on touch screen doesn’t
change SD settings).
The wind data is the average, minimum and maximum over interval set in the USB-menu unless an
alarm is active.
When an alarm is active the storage interval will be set to 5s. When the alarm is resolved the original set
interval will be used again.
All other data is the raw or actual data of the moment it is stored.
3.4 Functional information
In case the display is not able to write to the SD card, the user is notified with the following message in
the main screen: ‘SD fault’.
On the info tab page the following information is available in the bottom line:
SD card status: SD-Card OK
Insert SD-Card SD-card missing, not accessible or full
Please insert or replace an SD-card
Available space in percentage It will take one Storage interval before the correct value
is displayed (after card-insertion or power cycle).
Storage Interval 5 seconds, 2 minutes
or 10 minutes.

- If you do need to replace the card, use a simular SanDisk Ultra card
Not all SD cards are suitable fort he OMC-140 display!
Contact Observator if in doubt.
- If you do need to format a SD card: use SD-formatter from the SD
Association (www.SDcard.org) instead of the standard Windows format
function!

3.7 Data Format
The data is stored in an identical format as used by Observator data loggers. So the data can be
imported in OMC-Data Online.
Data is stored in .txt file per day.
The file starts with a header followed by data lines.
The header contains the parameter to parameter number link and other data required for OMC-Data
online.
Data is stored per data line format:
D; dd/mm/yy hh:mm:ss;parameter-number;data;status……parameter-number; data;status [CR] [LF]
Example:
T;0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24;25;26;27;28;29;30;31;
