The fourth yellow command key will be labeled 
“Read Next”. Press this key to extract the data from 
the other marker.
All the information retrieved from the marker, including the date and time read, is 
saved into the ‘Read History’ file of the receiver. If a hand-held GPS device is used in 
conjunction with the receiver, coordinates can be saved into the Read History also. (See 
Reviewing Marker Read/Write History, Section 17)
17. Reviewing Marker Read/Write History

2.  Press  Marker Details [SK] to view all data that 
was retrieved from the marker.
3.  Press  Read History [SK] to return to list or press 
Exit  [SK] to return to Data/Template review 
display.

18. GPS Operation
A. Communicating with the GPS Device
Menu [6] + COM Setup [SK:3]
The Com Setup [SK:3] display will toggle through several options to configure the 
Serial Port [15] ([14] on 2250M) of the receiver (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 data to and receive data from 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.
Log Prompt = On – Before the receiver returns to locate mode, a verification screen 
will appear on the receiver display asking if you want to log this point. Press Locate/OK 
[5] to send data to the GPS device.
Log Prompt = Off – When the receiver returns to locate mode, the locate information 
will be sent automatically to the GPS device.
B.  Capturing the GPS Coordinates (Capture Mode / Mode 1)
Menu [6] + COM Setup [SK:3] + NMEA
If the GPS device is not configured properly, there is an error communicating with the 
receiver, or the GPS has not acquired enough satellites to pinpoint the location, the 
receiver will display the message “Insert External Device”. 
						

							78-8130-6150-0 Rev G 53
When the receiver is communicating with a GPS 
device, the LAT and LONG coordinates received 
from the GPS device will appear on the marker 
locate display.
1. Locate a marker (See 13.C, Single Marker Locating.)
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.
C.  Sending 3M iD Marker Data to GPS (Capture-Transmit Mode / Mode 
2)
Menu [6] + COM Setup [SK:3] + GIS
Receivers that have marker locating capability (indicated by ‘iD’ in the model number) 
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 M-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 to 
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 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.
If ArcPad
™ Software is the mapping software on the mobile device, download the 3M 
software application script from the website:  www.3M.com/dynatel
With ArcPad
™ application installed, the receiver will send the path information (locate 
frequency, depth, current, and trace template information) into the software program as a 
logged point and can be saved as a .shp file.

1. Creating Trace Templates
The easiest way to create a Trace template is using the 3M™ Dynatel™ PC Tools 
Software. The 3M™ Dynatel™ PC Tools software is available free of charge at www.3M.
com/dynatel under the Software section; 2550/2573/2250M/2273M/1420 Locator PC 
Tools xx.x.x (EXE xx.xMB).
•  Create a TRACE template.
•  Save and download the template to the receiver.
Up to four Trace Templates can be stored on the Receiver.
Each Trace template is limited to 132 user editable characters.
The trace template appears in table format: two columns with six lines.
The first column is limited to 8 characters and the second column is limited to 14 
characters. In addition to the 132 character table, the receiver will send a sequence 
number, the frequency, the measured depth of the conductor, and the current to the GPS.
2. Select Com Port Setting
Menu [6] + Com [SK:3] + GIS [SK] (or PDA [SK])
If the GPS device has the ability to send NMEA coordinates on its com port and has the 
ability to receive information at 4800 baud, set the receiver’s com port to GIS.
If the GPS device only has the ability to receive information, set the com port of the 
receiver to PDA mode.
Log Prompt = On: Before the receiver returns to locate mode, a verification display 
will display on the receiver with the trace template information that will be sent to the 
GPS device. This information can be modified and confirmed. Press OK to send to the 
GPS device.
Log Prompt = Off: When the receiver returns to locate mode, the trace template and 
locate information will be sent automatically to the GPS device.
3. Sending Path Information to GPS Device
1.  Establish communication with the GPS device.
2.  Set COM port on receiver.
3.  Locate target utility.
4.  Measure depth to target utility.
 
− If Log prompt is activated, when the Locate/OK [5] button is pressed (or after a 
five second delay), a display will appear that displays the path information.
5.  Press  Locate/OK  [5] to send the information to the GPS device, or Exit  to abort the 
exchange.
