18. GPS Compatibility Operation
A. Communicating with the GPS Unit
Menu [6] + COM Setup [SK:3]
The COM Setup [SK:3] key will toggle through several options to configure the Serial
Port [14] of the locator (depending on the application, or capabilities of the GPS device).
Select from the following options.
NMEA – The Serial Port is configured to receive NMEA signals from a GPS device
(4800 Baud Rate). (Capture Mode/Mode 1)
GIS – The Serial Port is configured to send and receive data to a GPS device that has
GIS mapping capabilities. (Capture/Transmit Mode/ Mode2)
PC – The Serial Port is configured to communicate with a computer for the Dynatel PC
Tool Kit application.
PDA - The Serial Port is configured to only send information if the GPS device only has
the ability to receive information.
B. Capturing the GPS Coordinates (Capture Mode / Mode 1)
Menu/OK [5:Toggle to MAIN MENU] +
[SK:3] + NMEA
If the GPS device is not configured properly, there is an error communicating with the
receiver, or the GPS device has not acquired enough satellites to pinpoint the location, the
receiver will display the message "Insert External Device".
When the receiver is communicating with a GPS
device, the LAT and LONG coordinates received
from the device will appear on the marker locate
display.
Step 1. Locate a marker (See 4. D. Single Marker Locate.)
Step 2. Press Read [SK]
The information from the 3M™ iD Marker, as well as the GPS coordinates, will display
on the receiver display. This information is saved automatically in the Read Marker
History. (See 17. Reviewing Marker Read/Write History)
If the marker is a passive marker (rather than iD) the receiver will display "No iD Marker
Found". The GPS coordinates of the attempt to read the non-iD marker are stored in
the Read Marker History as serial number # 0000-0000-0000. The marker details will
indicate "not an iD marker", but will display the GPS coordinates.
