GPS Menu
The GPS menu is used to setup the DAQlink III for GPS position and timing.
Normally an external GPS unit is used. The baud rate selection is made with the Baud
rate software switch.
To use the standard Garmin GPS unit sold from Seismic Source, select External and
19.2K baud rate.
The GGA string should appear when the correct baud rate has been selected.
Press the “Get Position” button to verify that the GPS unit has a valid position and the
GPS PPS pulse is wired correctly to the DAQlink III.
