C. Sending 3M iD Marker Data to GPS (Capture-Transmit Mode / Mode 2
)
Menu [6] + COM Setup [SK:3] + GIS
Locators that have marker locating capability (indicated by ‘iD’ in the model number
or description) can be configured to send 3M™ iD Marker data directly to some GPS
devices. When an iD marker is located and read, the information read from the iD
marker, with feature and attribute data, is sent to the GPS device and is stamped with
latitude, longitude and date/time data. The data acquired during this logging process can
be uploaded to GIS mapping software. For more information and detailed instructions
pertaining to specific GPS devices, refer to www.3M.com/dynatel for GPS instruction
sheet.
D. Path Mapping with GPS
The 3M™ Dynatel™ Locator 7500 Series cable and pipe locators are compatible with
hand-held GPS devices and now have the ability to map the path of underground target
facilities. While measuring the depth to the target, the technician can automatically log
the coordinates of the path on the GPS device. These logged points contain the Trace
template that can have valuable information regarding the facility (owner, utility, size,
etc.) and the method used to find the path (frequency, current, and measured depth).
In order to transmit the path information to a GPS device, the GPS device has to have
the ability to accept information on one of its com ports at 4800 Baud. Using the manual
supplied with the GPS device, configure the com port of the GPS to communicate with
the receiver.
