The GPS501 can be used as a GPS unit by connecting with a PC or other device which can
interpret NMEA version (3.01) data.
The GPS501 continuously outputs NMEA sentences via the USB socket. This is only
interrupted if it receives a connection request from the Update Software, see PC UPDATES
page 32. (The NMEA output continues after it receives the cancel request.)
