GPS The SoundPro has the capability of embedding GPS information into s tudy
headers. To interface a GPS, you need a GPS recei ver with RS-232
communications that conform to NMEA 0183 version 2 and the optional 053-
729 Serial Cable. In many cases, a Male-Male DB-9 null modem connector
will be required as well.
The SoundPro will keep a GPS fix for up to 1 minute before declaring it
invalid at which time “No Fix” will appear if you are in t he “COMM-SET”
menu. In other screens where a RUN may be initiate d, “GPS +” or “GPS-” is
momentarily flashed in the Right Soft key indicating either a valid fix “GPS +”
or an invalid or timed out fix “G PS-”.
NOTE: GPS time can be viewed in the Comm Set screen but is not used in
the instrument or added to session files. Time and dat e stamping in session
files uses information that is manually entered (“ Ti me and date ” on pag e 25)
or downloaded from QSP II (“Information screen” on page 8).

GPS display

You can view GPS data in the Comm-Set screen. T he position coordinates
are stored in each study, when GPS is enabled and can be viewed with DMS
(see page 9 for details.)
