5.4 ASCIITime Code Data Formats
This section describes the different time code data format selections available for use with NetC
lock option cards that accept ASCII data streams as inputs or outputs via their RS-485 and RS-
232 interfaces.
Supported are formats like NMEA, BBC, Spectracom, GSSIP, and Endrun.
5.4.1 NMEA GGA Message
The GGA Format provides essential fix data which includes 3D location and accuracy data.
E x a m p l e m e s s a g e :
$GPGGA,123519.00,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47
NOTE: The GGA format does not support precision timing and 1PPS functionality; the WebUI
may permit the selection of Message or PPS Pin as PPS Source, but the NMEA GGA Message
will not use either. If this data is required for your application, use the ZDA Message format
instead (see "NMEA ZDA Message" on page389).
