Hi,
I would like to parse the Lat and Long from an NMEA GGA string coming on COM 1 and then transmit it on COM 2. Is this possible? If so, what are the steps/modules I require? Do I need to use the DDE or OPC Server?
Thanks,
Terry
Hello Terry,
Yes, it is possible. You need
You need:
1. The Enterprise or trial version of the logger;
2. Create 2 different configurations (COM1, COM2);
3. For COM1 activate the "Redirect data" filter plug-in (http://www.aggsoft.com/serial-data-logger/plugins/dataredirect.htm). This plug-in can send data from a parser variable to a port of another configuration;
4. If you need to combine a string from NMEA values, then activate the "Expressions" plug-in, place it before the the "Data redirector" filter plug-in and make a corresponding expression.
OK, that is helpful. How do I parse the NMEA string to give ONLY:
"GGA_Latitude, GGA_Longitude"
In that format?
Thanks again!
What our logger do you use? NMEA logger?
yes, NMEA logger. I can see the variable names but I don't know how to stream ONLY:
"GGA_LATITUDE, GGA_LONGITUDE"
to the output COM port.
I don't want any other data streamed. It's because my program only wants position data streamed in that format; it doesn't recognice NMEA.
Please, look for attached images. I've verified it.
