NMEA Input
NMEA_Module

NMEA_String
The name of the NMEA string containing the data
NMEA_Position
The position of the first (Latitude) data item in the NMEA string. Strings are comma separated, the 0’the item will be the string name, the 1’st item the one after that, etc.
Two numbers will in face be read from the NMEA string. It is assumed that Latitude is at the position given by NMEA_Position and that the next number in the NMEA string (i.e. NMEA_Position+1) is the Longitude. Teh latitude and longitude should be in decimal degrees. If conversion of either number fails, the values will be set to null.
